This adds an initial (and already working), generic API for defining, handling and drawing of table UIs.
It supports two types of tables:
* Vertical flow: Rows are all in a vertical stack.
* Horizontal flow: Rows are stacked vertically, until some threshold height is reached. The table is then split into another vertical stack that is drawn next to the former one. Such drawing could be used for the file browser in non-thumbnail mode.
A table is built out of - guess what - rows and columns. The API allows defining new collumns (identified by an id-name) and inserting new rows at any point. When drawing, we draw a cell for each column/row combination, using a custom cell-drawing callback.
The uiTable API will probably get some support for drawing buttons (uiBut) into custom layouts (uiLayout).
The API is written with big data sets in mind. In future we may get a spreadsheet view where data like all vertices of a mesh is displayed. That would result in thousands of rows, the uiTable API should be ready for this.
This includes a few fixes in the MBC_ api.
The idea here is for this to be the only interface the render engines
will deal with for the meshes.
If we need to expose special options for sculpting engine we refactor
this accordingly. But for now we are shaping this in a per-case base.
Note:
* We still need to hook up to the depsgraph to force clear/update of
batch_cache when mesh changes
(I'm waiting for Sergey Sharybin's depsgraph update for this though)
* Also ideally we could/should use BMesh directly instead of
DerivedMesh, but this will do for now.
Note 2:
In the end I renamed the `BKE_mesh_render` functions to `static
mesh_render`. We can re-expose them as BKE_* later once we need it.

We started to run out of bits there, so now we separate flags
which came from __object_flags and which are either runtime or
coming from __shader_flags.
Rule now is: SD_OBJECT_* flags are to be tested against new
object_flags field of ShaderData, all the rest flags are to
be tested against flags field of ShaderData.
There should be no user-visible changes, and time difference
should be minimal. In fact, from tests here can only see hardly
measurable difference and sometimes the new code is somewhat
faster (all within a noise floor, so hard to tell for sure).

Cycles add-on did not actually support reloading correctly.
When you want to correctly reload sub-modules (i.e. modules of an add-on
which is a package), you need to use importlib, a mere import will do
nothing with already loaded modules (RNA classes are sort of
pre-registered when they are evaluated, through the meta-class system).
New options to define the style of the animation paths in order to get
better visibility in complex scenes.
Now is possible define the color, thickness and several options relative
to the style of the lines used to draw motion path.
This way we can stop traversing BVH node early on.
Gives about 2-2.5x times render time improvement with 3 BVH steps.
Hopefully this gives no measurable performance loss for scenes with
single BVH step.
Traversal is currently only implemented for QBVH, meaning old CPUs
and GPU do not benefit from this change.
Similar to the previous commit, the statistics goes as:
BVH Steps Render time (sec) Memory usage (MB)
0 46 260
1 27 373
2 18 598
3 15 826
Scene used for the tests is the agent's body from one of the barber
shop scenes (no textures or anything, just a diffuse material).
Once again this is limited to regular (non-spatial split) BVH,
Support of spatial split to this feature will come later.
The idea is to create several smaller BVH nodes for each of the motion
curve primitives. This acts as a forced spatial split for the single
primitive.
This gives up render time speedup of motion blurred hair in the cost
of extra memory usage. The numbers goes as:
BVH Steps Render time (sec) Memory usage (MB)
0 258 191
1 123 278
2 69 453
3 43 627
Scene used for the tests is the agent's hair from one of the barber
shop scenes.
Currently it's only limited to scenes without spatial split enabled,
since the spatial split builder requires some changes to work properly
with motion steps coordinates.
Also fixed some issues with motion keys calculation:
- Clamp lower and upper limits of curves so we can safely call those
functions for the very first and very last curve segment.
- Fixed wrong indexing for the curve radius array.
- Fixed wrong motion attribute offset calculation.
Mimics how regular triangles are working and makes it more clear where

This is important for the reliable behavior or isnan/isfinite/min/max

Please NEVER EVER use such a statement, it's only causing HUGE

Experimental option for the Reproject Strokes operator to project strokes on to
geometry, instead of only doing this in a planar (i.e. parallel to viewplane) way.
The current implementation is quite rough, and may need to be improved before it
is really ready for use. Potential issues:
* Loss of precision (i.e. stairstepping artifacts) from the 3D -> 2D -> 3D conversion
as we don't have float version of one of the projection funcs
* Jagged depth if there are gaps, since it will default back to the 3d-cursor plane
if no geometry was found (instead of doing some fancy interpolation scheme)
* I'm not sure if it's that useful for adapting GP strokes to deforming geometry yet...
Now the eraser checks if there's an active frame with some strokes in it
before creating a new frame. There's no point in creating a new frame if
there are no strokes in the active frame (if one exists).
This still doesn't help much if there were strokes but they weren't touched though...
This operator adds a new frame with nothing in it on the current frame.
If there is already a frame there, all existing frames are shifted one frame later.
Quite often when animating, you may want a quick way to get a blank frame,
ready to start drawing something new. Or maybe you just need a quick way to
add a "placeholder" frame so that a suddenly-appearing element does not show
up before its time.
If the layers or the colors were renamed, the animation data was wrong
because the data path was not updated.
I also have fixed a possible stroke color name update if the name was duplicated moving
the rename function call after checking unique name.
Avoids possible jumps when one is trying to do some really preciese tweak.
Quite striaghtforward change for mouse input initialization: take Shift
state into account. However, this will interfere with the axis exclusion
which is currently also uses Shift (the feature to move something in a
plane which doesn't have selected axis). This is probably not so commonly
used feature (nobody in the studio even knew of it) and the only downside
now would be that such a constrainted movement will become accurate by
default. That's easy to deal from user side by just unholding Shift key.

To make it faster to try different interpolation curves, there's a new operator
"Remove Breakdowns" which will delete all breakdowns sandwiched by normal
keyframes (i.e. all the ones that the previous run of the Interpolation op created)
This commit introduces the ability to use the Robert Penner easing equations
or a Custom Curve to control the way that the "Interpolate Sequence" operator
interpolates between keyframes. Previously, it was only possible to get linear
interpolation between the gp frames.
Workflow:
1) Place current frame between a pair of GP keyframes
2) Open the "Interpolate" panel in the Toolshelf
3) Choose the interpolation type (under "Sequence Options")
4) Adjust settings (e.g. if you're using "Custom Curve", use the curvemap widget
to define the way that the interpolation proceeds)
5) Click "Sequence" to interpolate
6) Play back/scrub the animation to see if you've got the result you want
7) If you need to make some tweaks, undo, or delete the generated keyframes,
then repeat the process again from step 4 until you've got the desired result.
The "gp_sculpt" settings should be strictly for stroke sculpting, and not abused by
other tools. (Similarly, if other general GP tools need one-off options, those should
go into the normal toolsettings->gpencil_flag)
Furthermore, this paves the way for introducing new settings for controlling the way
that GP interpolation takes place (e.g. with easing equations, or a custom curvemap)
* Reshuffled some blocks of code for better ease of navigation/flow in the file
* Improved some tooltips
* Removed "Helper" tag from some functions that serve bigger roles
* Fixed some errant formatting
The interpolation operators (and their associated code) occupied a significant
portion of gpencil_edit.c (which was getting a bit heavy). So, it's best to split
these out into a separate file to make things easier to handle, in preparation
for some further dev work.
After revert the commit rB4b99958ca12642, the line added at the end of the enum is not necessary anymore because it is replaced by the corresponding element in the list in the right position.
Things like `BLI_uniquename` had nothing, but really nothing to do in
BLI_path_util files!
Also, got rid of length limitation in `BLI_uniquename_cb`, we can use
alloca here to avoid overhead of malloc while keeping free size (within
reasonable limits of course).
Just store bones that could not get renamed to desired flipped name on the
first try into a temp list, and try to rename them a second time.
This is rather simple solution, will induce 'over numbering' in case you
flip a bone to another unselected bone's name (since number will be
incremented in both rename attempts), but think this is acceptable minor
glitch, for a corner case situation that does not have any good
resolution anyway.
Also, set `strip_numbers` option of `BKE_deform_flip_side_name` to
false, otherwise chains of bones with same names would get their numbers
completely messed up after name flipping.

It is quite likely in a triangulated mesh that the actual island edge
belongs to a different triangle than the current pixel; for example
consider corners of a triangulated axis aligned rectangle face that
have the additional edge: a pixel there will have to be assigned to
one of the triangles, but one of the edges of the original rectangle
can only be accessed through the other triangle.
Thus for robust operation it is necessary to do a recursive search.
The search is limited by requiring that it only goes through edges
that bring it closer to the target point, and also by depth as a
safeguard.
Differential Revision: https://developer.blender.org/D2409
The code requires the pixel on the other side of the seam to be assigned
precisely to the expected triangle. This can cause false negatives around
vertices, where a pixel is likely to touch multiple triangles and thus
cannot be said to unambiguously belong to any one of them, so check
distance to the intended triangle and accept the result if it's close.
1. Forcibly symmetrize the neighbor relations, so that if A is neighbor
of B, B is neighbor of A. The existing code is guaranteed to violate
this if texture resolution is different between the sides of a seam.
2. In texture mode dynamic paint adds a 1 pixel wide border around the
islands. These pixels aren't really part of the dynamic paint domain
and thus by design can't have symmetrical neighbor relations. This
means they can't be treated by effects like normal pixels.
The simplest way to handle it in a consistent way is to exclude
them from effects, but add an additional pass that recomputes them
as average of their non-border neighbors, located on both sides of
the seam.
This avoids intersection AABB of different curve primitives
which makes it less ray-to-primitive intersections.
This gives about 30% speedup of hair rendering in the barber
shop scenes here. There is still some work to be done on those
files to solve major speed issues on certain frames.
This way we can have different limits for regular and motion curves
which we'll do in one of the upcoming commits in order to gain some
percents of speedup.
The reasoning here is that motion curves are usually intersecting
lots of others bounding boxes, which makes it inefficient to have
single primitive in the leaf node.
Maximal number of elements is supposed to be inclusive. That is what
it was always meant in this file and what @brecht considered still
the case in 6974b69c61.
In fact, the commit message to that change mentions that we allowed
up to 2 curve primitives per leaf while in fact it was doing up to 1
curve primitive.
Making it real 2 primitives at a max gives about 5% slowdown for the
koro.blend scene. This is a reason why BVHParams.max_curve_leaf_size
was changed to 1 by this change.
Since the beginning of times hair settings in cycles were global for
the whole scene but were located in the particle context. This causes
quite some trickery to get shots set up for the movies here in the
studio by forcing artists to create dummy particle system to change
settings of hair on the shot.
While ideally this settings should be properly become per-particle
system for the time being it will save sweat and blood to move the
settings to scene context.

It is now also possible to enable colored messages using magic

The issue was that we used to compare number of vertices for mesh after the auto
smooth was applied (at the center of the shutter time) with number of vertices
prior to the auto smooth applied. This caused false-positive consideration of a
mesh as changing topology.
Now we do autosplit as early as possible and do it from blender side, so Cycles
does not need to re-implement splitting on it's side.
This way render engine can request mesh to be auto-split and not
worry about implementing this functionality on it's own.
Please note that this split is to be performed prior to tessellation.
Other than implementing a `mid_v3_v3_array` function, this removes

Am pretty sure node update should not touch to Main database like that,

If the active object is in weight paint mode, but some armatures in pose mode, 'manipulate center points' still affects the transformation. See bd2034a749.
Also removed redundant check, we basically did the same check for paint modes twice.
If a very low wetness absolute alpha brush is used with spread and
drying effects enabled, some pixels will rapidly accumulate paint.
This happens because paint drying code applies a minimal wetness
threshold that causes the paint to instantly dry out.
Specifically, every frame the brush adds paint at the specified
absolute alpha and wetness set to the minimal threshold, spread
drops it below threshold, and finally drying moves all paint to
the dry layer. This drastically accelerates the rate of flow of
paint into the affected pixels.
Fortunately, the reason paint spread actually ends up decreasing
wetness turns out to be a simple floating point precision problem,
which can be easily fixed by restructuring the affected expression.

Root of the issue was that opening a new text file would create

This was leaving Text datablocks in inconsitent user count, and
generating asserts in BKE_library area.

Main issue here was that in old usercount system 'user_real' did simply
not allow that kind of thing to work. With new pait of 'USER_EXTRA'

The settings.frame_start rna was clamping frame start to frame end when frame start was bigger than frame end.

This is a hacky fix for a regression introduced sometime after 2.76.
The "Strip Time" setting on NLA Strips could not be edited without the
value immediately jumping back to the current FCurve value (or 0.0 if no
keyframes existed); even enabling autokey wouldn't let you key the property.
Until we have proper overrides (that only lose their values on frame change),
it's best that this setting is editable, even if it does mean it you have to
manually change the frame to see the updated values.
Sometimes it can be useful to be able to keep onion skins visible in the
OpenGL renders and/or when doing animation playback. In particular, there
are two use cases where this is quite useful:
1) For creating a cheap motion-blur effect, especially when the before/after
values are also animated.
2) If you've animated a shot with onion skinning enabled, the poses may end
up looking odd if the ghosts are not shown (as you may have been accounting
for the ghosts when making the compositions).
This option can be found as the small "camera" toggle between the "Use Onion Skinning"

This is the same issue as was fixed with T39486: the adjustment pass
that tries to equalize different widths at either end of an edge
sometimes causes the widths to get bigger and bigger.
The previous fix was to let "clamp_overlap" do double duty as a way
to limit this behavior. But clearly this is undiscoverable, as the
current bug report shows. So I put in an "auto-limiting" mode that
detects when adjustments are going crazy and then acts as if
clamp_overlap were set.
The reason we can't always act as if clamp_overlap is set is that
certain models (e.g., Bent_test in regression tests) look bad if

Over time roll and orbit would scale the quaternion

In practice any errors would be subtle,
but better normalize as other operators do.
Basic idea is to store fileversion in Library datablock, and split again
Main by libraries after lib linking, do_versions_after_liblink on
those separated Mains, and merge again.
This allows to still have correct versions for each data-block in that
second do_versions step.
Note that this is not used currently in master (might be soon, though),
but is needed for 2.8 work.
Main scheduler would be created way before `-t` argument would be
parsed, since it was on forth pass! Moved it to first pass of argparse,
that kind of stuff should be initialized asap on startup.
When linking data-blocks from same library in several steps, the already

Note: only fixed for libraries, I can't imagine how this could happen

Data transfer was not checking if the required geometry existed, thus
causing a segfault when it didn't. This adds the required checks, and
reports errors if geometry is missing.

It's now possible to change the shortcut that enables planar transformation with the transform manipulators (shift+LMB on axis).
This actually fixes the workaround added in rB20681f49801fd. Thing is that we needed to allow using the manipulators, even if a modifier key is held so things like snapping work right away. That's why normal LMB behavior uses KM_ANY. However, event handling would always execute the KM_ANY keymap handler because it's iterated over first. Simply solved this by registering the KM_SHIFT keymap item first, so it has priority over the KM_ANY one.

Reading rest of the code, it's obvious we want to start à YOFF lines
from start of rect2i, so we have to also multiply by number of
components.
Also did some minor cleanup.
Code was not accounting for possibilities that width or height of given
buffers may be smaller than XOFF/YOFF...
Note that I seriously doubt that drop code actually works (as in, gives
expected results) when applied to tiles like it seems to be done
currently, but this is much more complex (and involved) topic.
compiled.
This adds a short message to the smoke, remesh and boolean modifiers' UI
when trying to use them when their compilation was turned off. This was
already implemented for the fluid and ocean simulation modifiers.
This also makes the 'quick fluid' and 'quick smoke' operator abort and
report when trying to use them when unavailable.
This kind of keeps threads "warmer" and should in theory give better
cache coherency bringing some %% of speedup. It was already tested
few months ago and it gave few % speedup in barber shop, but was
reverted due to some bone popping. The popping is now fixed so it
should be fine to use new scheduling policy.
Shuffle existing code, hook it up to the new (& old) viewport.
Also the 3D mouse rotation guide for NEW viewport only. Minor feature not worth enabling for legacy 3D view.
This sets forces to zero, when Nabla is zero and a grayscale texture is
used or texture mode is Gradient or Curl.
Nabla equal to zero was causing a zero division, and forces ended up
being set to `nan`.

Own error when changing order,

- Expand overly dense & confusing delta assignments.
- Replace bit shift with multiply.

which may be useful to add later.
The Progress system in Cycles had two limitations so far:
- It just counted tiles, but ignored their size. For example, when rendering a 600x500 image with 512x512 tiles, the right 88x500 tile would count for 50% of the progress, although it only covers 15% of the image.
- Scene update time was incorrectly counted as rendering time - therefore, the remaining time started very long and gradually decreased.
This patch fixes both problems:
First of all, the Progress now has a function to ignore time spans, and that is used to ignore scene update time.
The larger change is the tile size: Instead of counting samples per tile, so that the final value is num_samples*num_tiles, the code now counts every sample for every pixel, so that the final value is num_samples*num_pixels.
Along with that, some unused variables were removed from the Progress and Session classes.

Quite handy for debugging.
Unfortunately, this doesn't support viewport tweaks yet since those
require GLSL for colorspace conversion. Maybe this will be implemented
as well one day in the future..
They are defined for MSVC but seems to be missing in GCC and CLang-3.8.
Maybe some further tweaks to policy when to define those functions is
needed, but should be fine for now.
I can no longer reproduce crash with neither of the files where
the crash was originally visible. This is something where other
changes (light threshold, sampling) had an effect and made code
to work as it is supposed to. Could have been optimizator issue
or something like that.
Let's see if we hit same issue again.
`IMB_remakemipmap` may 'shrink' the mipmap list without actually freeing
anything, so we need to check all possible levels in `imb_freemipmapImBuf`
to avoid memory leaks, not only those currently used.
Basically all this does is drawing layout previews into the opened layout search menu.
https://youtu.be/RHYWtZP7pyA
The previews are drawn using offscreen rendering so they can't use multi-threading (yet!). But that shouldn't be an issue since only a handful of previews are drawn at the same time. Normally we only need to redraw the preview if a screen layout was changed. Would be nice if PreviewImage could store if it supports threaded rendering.
Previews are saved in files, might be useful if you later want to support appending layouts.
Adds a new file screen_draw.c.
In ccgDM and emDM, looptri array recalculation was being handled
directly by `*DM_getLoopTriArray` (`getLoopTriArray` callback), while
`*DM_recalcLoopTri` (`recalcLoopTri` callback) was doing nothing.
This results in the array not being recalculated when other functions
that depend on the array data called the recalc function.
This moves all the recalculation code to `*DM_recalcLoopTri` and makes
`*DM_getLoopTriArray` call that.
This commit also makes a minor change to the `getNumLoopTri` function,
so that it returns the correct number without having to recalculate the

Most of them are harmless implicit conversions (e.g. Alembic deals with
doubles for storing time information when Blender uses both ints and
floats/doubles) or class/struct mismatch on forward declarations.
This aims at always ensuring that ID.newid (and relevant LIB_TAG_NEW)
stay in clean (i.e. cleared) state by default.
To achieve this, instead of clearing after all id copy call (would be
horribly noisy, and bad for performances), we try to completely remove
the setting of id->newid by default when copying a new ID.
This implies that areas actually needing that info (mainly, object editing
area (make single user...) and make local area) have to ensure they set
it themselves as needed.
This is far from simple change, many complex code paths to consider, so
will need some serious testing. :/
Was a ground work for some more improvements here, but got dragged
to some other studio maintenance job here.
The plan would be to enable exposure/gamma control for fallback mode
which will definitely be really handy for development and might be
handy for cases when OCIO config can not be read.
Crash is due by mismatching loops and faces counts between the Alembic
data and the Blender derivedmesh which does not appear so
straightforward to fix (the crash happens deep in the derivedmesh code).
So for now, try to detect if the topology has changed and if so, both
only read vertices (vertex colors and UVs won't be read, as tied to face
loops) and add a warning message in the modifier's UI to let the user
know.
The idea is simple: cache PD resolution from cache_point_density() RNA
function because that one is supposed to be called while database is
locked for original synchronization.
Ideally we would also pass array size to the sampling function, but
it turned out to be quite problematic because API only accepts int type
and passing size_t might cause some weird behavior.
This is a way to avoid possible memory corruption when render threads works
in parallel with UI thread.
Not guarantees complete safe, but makes things easier to check anyway.
This fixes multiple problems on latest Mac OS + Xcode. Hopefully does not cause any on other platforms.
The Xcode detection logic could use further cleanup. It's checking several old versions that are unsupported for Blender 2.8+ development.
Needed because deps graph can destroy objects from any thread. We ran into the same problem & solved it in GPU_buffers.
Implemented in C++11 since it provides the needed machinery. The interface is in C like the rest of Gawain.
This means editing a property will now always affect all selected objects, bones or sequencer strips. Support for this was added in rBdfbb876d4660 but you had to hold the Alt-key to use it. The old behavior of only editing the active object will not be kept like decided in the 2.8 workflow meeting (reports comming). If you only want to edit the active object, you have to deselect others.
There are still a couple of issues to be resolved (listed below), but having it enabled by default helps testing and getting used to it and should motivate us to fix them ;)
To be fixed:
* Give users hint when edits are applied to all objects/bones/strips ("Applying to x objects") - there are ideas but we need to finalize and implement them
* Make it work better in corner cases (material editing, modifier property editing, etc)
Note: Values usually override the initial value of the object/bones/strips, except of number buttons where it depends if you enter the value (absolute override) or drag the value (add value change). This behavior is consistent with multi-button editing.
To bring the API more into line with the UI (and the general expected behaviour of
Blender when it comes to adding stuff), newly created layers and palettes will be
made the active ones by default. It's possible to override this behaviour still
(e.g. in cases where you're auto-generating a large number of them), but otherwise,
this change will help prevent errors like T50123.
When there were no prior palettes, creating a new one didn't automatically make it active.
This caused problems when trying to rename the color, as the RNA code assumed that if there's
a color, it must come from the active palette.
This commit partially fixes the problem by ensuring that if there are no palettes, the first
one will always be made active.
- Remove 'rotate_m2', unlike 'rotate_m4' it created a new matrix
duplicating 'angle_to_mat2' - now used instead.
(better avoid matching functions having different behavior).
- Add 'axis_angle_to_mat4_single',
convenience wrapper for 'axis_angle_to_mat3_single'.
- Replace 'unit_m4(), rotate_m4()' with a single call to 'axis_angle_to_mat4_single'.
This is no longer needed since moving to MPoly/MLoop data structure.
Also use 3x3 matrix for transforming instead of quaternion
(slightly better performance).
Was giving huge artifacts in the barber shop file here in the studio,
Maybe not fully optimal solution, but committing it for now to have
closer look later.
All objects were being parented to a single instance of each parent
object, instead of their respective instances, when using dupliverts or
dupligroups.
Behavior was caused by the `persistent_id[0]` (vertex/face id) being
ignored when computing `parent_gh` hash, which caused all instances to
have the same hash, and thus only the first one was included.

Was affecting armatures' pose drawing code, could try to draw with
non-updated pose, which may contain NULL bone pointers (e.g. after some
data-block management tool execution, like make local, remapping, etc.).
Main intention is to give some quick way to control scene's memory
usage by clamping textures which are too big. This is really handy
on the early production stages when you first create really nice
looking hi-res textures and only when it all works and approved
start investing time on optimizing your scene.
This is a new option in Scene Simplify panel and it acts as
following: when texture size is bigger than the given value it'll
be scaled down by half for until it fits into given limit.
There are various possible improvements, such as:
- Use threaded scaling using our own task manager.
This is actually one of the main reasons why image resize is
manually-implemented instead of using OIIO's resize. Other
reason here is that API seems limited to construct 3D texture
description easily.
- Vectorization of uchar4/float4/half4 textures.
- Use something smarter than box filter.
Was playing with some other filters, but not sure they are
really better: they kind of causes more fuzzy edges.
Even with such a TODOs in the code the option is already quite
useful.

This will make triple buffer used by default for such configuration.
Ideally we would switch to triple buffer on all platforms, but let's
do it in 2.8 branch and don't open can of worms in master now.
This should solve issues like T49945.
This is very confusing, in fact, and rna tooltip was wrong,
BKE_object_make_local_ex actually ensures we never have several proxies
of same object, since it always clears proxy when it has to copy object
to make it local...
What that RNA function is probably missing, though, is same logic as in
BKE_library_make_local to actually remap proxy from old linked object to
new local one.
I) `clear_proxy` parameter was not assigned to parm in RNA define code,
so 'pyfunc optional' flag was set to `new_id` parameter of `user_remap`
func - super ugly!
II) `clear_proxy` parameter itself, when set to False, would allow to
leave .blend file in invalid state (more than one proxy of same object),
this should never, ever be allowed in RNA API imho. Left the PAI
untouched for now, just disabled any effect from this parameter (hence
always clearing proxy when copying).
There is some define conflict between system headers and clew,
so delay include of clew.h as much as possible.]
This is something which needed to be done in the code before
the refactor, hopefully such change will still work.

On second and third thoughts, this should have been done that way since
the begining, cases were you just delete a few data-blocks without any
serious knowledge of their usages are much, much more frequent than
cases where you are deleting thousands of data-blocks and are sure they
are not used anywhere anymore...
Own fault, but really frustrated that this topic was only raised the day
after 2.78a was released. :(
This has nothing to do here (freeing is not unlinking/remapping!), and
was actually redoing something already taken care of by
`BKE_libblock_relink_ex()` call in `BKE_libblock_free_ex()`.
Also, gives some noticeable speedup when removing datablocks with
do_unlink=True, about 5 to 10% quicker e.g. when deleting all objects
from a py console, in a big production file...
This commit reverts part of a fix for T33275, but things are:
- I can not reproduce the original issue at all, so doesn't seem to
cause any regressions.
- It is really bad idea to do delayed initialization in the threaded
environment, it's a straight way to some nasty issues.
- We can't do things like this anyway because we go more granular,
meaning such a delayed initialization will fail in the case of
having several IK solvers (unless they properly accommodate to
changed bone head).
- Verified the fix with various files from Mango project and all of
them seems to work nice with new depednency graph now (old depsgraph
has some flickering, but it's not related on DEG itself, but on
an environment with lots of proxies and threaded evaluation and it
is not a new behavior).

Was Requested by @monio (see https://rightclickselect.com/p/sculpting/zpbbbc/dyntopo-better-scale-input-in-constant-detail-mode) and I think it's worth testing.
Motivations:
1) GLenum is too broad; tightly-defined enum just for this is safer.
2) enable a Vulkan future
New code should use these instead of GL_FLOAT etc. When all existing code has been updated to use new enum, we can drop compatibility with GLenum values.
Early work towards 10_10_10 format, more to come soon.
Do not set 'real user' to groups every time we run the first clearing loop.
And do fully clear properly LIB_TAG_DOIT (this is not yet enforced in
existing code, but would love to get to that stage in future, so let's
do it at least with new code!).
Basic idea is to split first loop in two, and run checks before making
anything actually local, to detect data-blocks that we can directly make
local (because we are sure they are only used by already/future local
datablocks).
This allows to avoid a lot of overhead in later 'cleanup' steps of this
function, here with barbershop shot it's four times quicker (from 190s to 48s).
We are still far from the instantaneous results of MakeLocal in 2.77,
but in that version main characters lose their connection to their
armature and remain static after makelocal, so guess new code is still
better. ;)
There are probably more optimizations possible here, but would rather
polish this area of code once we get rid of proxies, those really
make it a nightmare to work on.

Before this commit, the brush set was created with the first stroke

Culprit here was once more proxies. Think what was happening here was:
1) Both proxy and proxified armatures' PoseChannels were cleared
(needed after remapping due to Bone pointers being stored in pchans).
2) Proxy PoseChannels got rebuilt in `BKE_pose_rebuild_ex()`, which ends,
in proxy cases, by actually replacing rebuilt pchans by those from
the proxified object... which has not yet been rebuilt.
Fixed the issue by merely adding bone pointer to data copied from
original pchan into new 'from proxy' one... Sounds much, much safer and
sanier anyway, that way we can be sure bone pointer is actually pointing
to a bone of the object's armature (this is supposed to be the same
Armature datablock between proxy and proxified objects, but that may not
be always true especially during makelocal process).
Did similar trick to old dependency graph: tag invisible relations for update.
Might need some re-consideration, see the comment.
This should solve our issues with powerlib addon here in the studio.
New dependency graph expects strict separation between nodes and relations builder,
meaning, if we try to create relation with an object which is not in the graph yet
we'll have an error in depsgraph.
Now, so far object nodes were created from bases of the current scene, which caused
missing objects in graph in certain cases.
Didn't find better approach than to simply ensure object nodes exists when we know
they'll be used by relation builder.
`kernel_path.h` and `kernel_path_branched.h` have a lot of conditional code and
it was kind of hard to tell what code belonged to which directive. Should be
easier to read now.
Caused by 4811b2d356 which caused the event handler hack that is used to fire up the file browser from other operators to fail. Basically the context from before the file browser is opened gets stored and used later for executing the actual file read/write operation (in this case, saving image). This context storage is cleared when exiting an editor since 4811b2d356, which is technically correct, but causes usage of NULLed context data in this case, because the file browser is exited before the file read/write operation is executed.
For now I solved this by moving the fileselect handler to list of normal handlers, instead of modal ones. 4811b2d356 only touches list of modal handlers so we avoid the crash. Ideally we'd completely refactor how the file browser opening works to get rid of these event handler hacks.
Note that I wouldn't be suprised if this causes other regressions, but I couldn't find one so worth a try.
Proxified objects can never be local, we can totally ignore them here.
This 'fixes' the asserts related to usercount when trying to remap poselib
of localized proxified objects (not sure what exactly was going on wrong here,
but proxies are a giant can of worms for sane data-blocks handling anyway :/).
This new `bpy.types.ID.make_local(clear_proxies=True)` allows Python
code to press the "Make Local" button on any ID block. I chose
`clear_proxies=True` as the default, since it's the default behaviour
of `id_make_local()` (defined in `library.c`).
The caller does need to take care of ensuring that linked-in objects
don't refer to local data, and that proxies aren't broken.

Gawain does very strict runtime checking to help us catch coding errors. Final release should disable most of these checks, so I'm disabling now for all non-debug builds.
When writing Blender code that uses Gawain, always make debug builds and test there! "make lite debug" is my favorite.
Right now this only affects other objects in wireframe. The idea is to do something similar for other draw modes, and keep focus on the edit object.

Most of this was already in place, just enabling & adding comments.
One fix was needed to make batch uniforms stick between multiple draws.
Added comments to selection outline; no functional changes there.
After CUDA dynload changes having CUDA toolkit became required
in order to compile Cycles. This only happened due to wrong
default value to the option.
The idea is simple: when falling back to one of the nodes which was partially
handled we "resume" checking outgoing relations from the index which we stopped.
This gives about 15-20% depsgraph construction time save.
This is more proper way to go:
- Avoids re-compilation of all dependent files when implementation changes
without changed API,
- Linker should have much simpler time now de-duplicating and getting rid
of redundant implementations.
The idea here is to address issue that name on it's own is not
always unique: for example, when adding driver operations the
name used for nodes is the RNA path (and multiple drivers can
write to different array indices of the path). Basically, now
it's possible to pass extra integer value to distinguish
operations in such cases.
So now we've already switched from sprintf() to construct unique
operation name to pass RNA path and array index.
There should be no functional changes yet, but this work is
required for further work about replacing string with const
char*.
There is no real reason to have nodes storing heap-allocated name
and description. Doing this increases amount of allocations during
dependency graph building, which usually means somewhat slowness.
We're temporarily loosing some eyecandy in the graphviz visualizer,
but those we can bring back as a part of graphiz dump (which happens
much less often than depsgraph build).
This will happen in multiple commits for the ease of bisect in the
future just in case this causes any regression. This commit contains
ID creation API changes.
Bullet spring constraint already supports rotational springs, but
they are not exposed in blender UI, likely due to a simple oversight.
Supporting them is as simple as adding a few DNA/RNA properties

Previously, it was only possible to choose a single GPU or all of that type (CUDA or OpenCL).
Now, a toggle button is displayed for every device.
These settings are tied to the PCI Bus ID of the devices, so they're consistent across hardware addition and removal (but not when swapping/moving cards).
From the code perspective, the more important change is that now, the compute device properties are stored in the Addon preferences of the Cycles addon, instead of directly in the User Preferences.
This allows for a cleaner implementation, removing the Cycles C API functions that were called by the RNA code to specify the enum items.
Note that this change is neither backwards- nor forwards-compatible, but since it's only a User Preference no existing files are broken.

We have to clear `newid` of all datablocks, not only object ones.
Note that this whole stuff is still using some kind of older, primitive
'ID remapping', would like to see whether we can replace it with new,
more generic one, but that's for another day.
Code would try to add multiple time the same key in `parent_gh` (for this
ghash a lot of dupliobjects may generate same key).
Was making the tool unusable in debug builds.
Also optimise things a bit by avoiding creating parent_gh when only
`use_base_parent` is set.
New code dealing with getting rid of lib-only cycles of data-blocks
could add several time the same datablock to the list of candidates. Now
this is avoided, and pointers are further cleaned up as double-safety
measure.
Feature request during bconf, makes sense to have it even as an hack for

be redone in bmesh once we have proper custom noramls handling in edit mode...
The issue was caused by image ID nodes not being in the depsgraph.
Now, tricky part: we only add nodes but do not add relations yet. Reasoning:
- It's currently important to only call editor's ID update callback to solve
the issue, without need to flush changes somewhere deeper.
- Adding relations might cause some unwanted updates, so will leave that for
a later investigation.
Basically, the problem here was that the transform that's used to bring texture coordinates
to world space is either fetched while setting up the shader (with Object Motion is enabled) or
fetched when needed (otherwise). That helps to save ShaderData memory on OpenCL when Object Motion isn't needed.
Now, if OM is enabled, the Lamp transform can just be stored inside the ShaderData as well. The original commit just assumed it is.
However, when it's not (on OpenCL by default, for example), there is no easy way to fetch it when needed, since the ShaderData doesn't
store the Lamp index.
So, for now the lamps just don't support local texture coordinates anymore when Object Motion is disabled.
To fix and support this properly, one of the following could be done:
- Just always pre-fetch the transform. Downside: Memory Usage increases when not using OM on OpenCL
- Add a variable to ShaderData that stores the Lamp ID to allow fetching it when needed
- Store the Lamp ID inside prim or object. Problem: Cycles currently checks these for whether an object was hit - these checks would need to be changed.
- Enable OM whenever a Texture Coordinate's Normal output is used. Downside: Might not actually be needed.
Animation system has separate fcurves for each of array elements and
dependency graph creates separate nodes for each of fcurve, This is
needed to keep granularity of updates, but causes issues because
animation system will actually write the whole array to property when
modifying single value (this is a limitation of RNA API).
Worked around by adding operation relation between array drivers
so we never write same array form multiple threads.
It was possible to have synchronization issues whe naccumulating smooth
normal to a vertex, causing shading artifacts during playback.
Bug found by Dalai, thanks!
They were not real issues, it's just some areas of code tried to create
relations between non-existing nodes without checking whether such
relations are really needed.
Now it should be easier to see real bugs printed.
Hopefully should be no regressions here.
Some platforms are having hard time using this linker so added an option
to not use it. The options is an advanced one and enabled by default so
should not cause any changes for current users.
Request from Hjalti Hjalmarsson for the animation work.
Basically a common part of the workflow of animation is to change the pose, scrub back and forth a few times and roll back the changes when unsatisfied.
However if you go back and forth too many times the UNDO stack would be full, and it would not be possible to bring back the previous pose.
I'm leaving clip_editor change frames as it is for now. But we can
probably change the behaviour there as well.
Issue here was that py API code was keeping references (pointers) to the
liniked data-blocks, which can actually be duplicated and then deleted
during the 'make local' process...
Would have like to find a better way than passing optional GHash to get
the oldid->newid mapping, but could not think of a better idea.
Radial append/remove had swapped args and *slightly* different behavior.

In scenes with many lights, some of them might have a very small contribution to some pixels, but the shadow rays are traced anyways.
To avoid that, this patch adds probabilistic termination to light samples - if the contribution before checking for shadowing is below a user-defined threshold, the sample will be discarded with probability (1 - (contribution / threshold)) and otherwise kept, but weighted more to remain unbiased.
This is the same approach that's also used in path termination based on length.
Note that the rendering remains unbiased with this option, it just adds a bit of noise - but if the setting is used moderately, the speedup gained easily outweighs the additional noise.

This avoids traversing the archive everytime object data is needed and
gives an overall consistent ~2x speedup here with files containing
between 136 and 500 Alembic objects. Also this somewhat nicely de-
duplicates code between data creation (upon import) and data streaming
(modifiers and constraints).
The only worying part is what happens when a CacheFile is deleted and/or
has its path changed. For now, we traverse the whole scene and for each
object using the CacheFile we free the pointer and NULL-ify it (see
BKE_cachefile_clean), but at some point this should be re-considered and
make use of the dependency graph.

Oh man, is it a compiler bug? Is it something we do stupid?

You only see the color if you use the "modern" viewport option

That said, in the "modern" viewport we have unfreed mem. To be
investigated separately.
There is some precision issues for big magnitude coordinates which started
to give weird behavior of release builds. Some weird memory usage in BVH
which is tricky to nail down because only happens in release builds and GDB
reports all variables as optimized out when trying to use RelWithDebInfo.
There are two things in this commit:
- Attempt to make vectorized code closer to original one, hoping that it'll
eliminate precision issue.
This seems to work for transform_point().
- Similar trick did not work for transform_direction() even tho absolute
error here is much smaller. For now disabled that function, need a more

Rewrite the current range-tree API used by dyn-topo undo
to avoid inefficiencies from stdc++'s set use.
- every call to `take_any` (called for all verts & faces)
removed and added to the set.
- further range adjustment also took 2x btree edits.
This patch inlines a btree which is modified in-place,
so common resizing operations don't need to perform a remove & insert.
Ranges are stored in a list so `take_any` can access the first item
without a btree lookup.
Since range-tree isn't a bottleneck in sculpting, this only gives minor speedups.
Measured approx ~15% overall faster calculation for sculpting,
although this number time doesn't include GPU updates and depends on how
much edits fragment the range-tree.
Existing method was fine for basic polygons but didn't scale well
because its was checking all coordinates for every y-pixel.
Heres an optimized version.
Basic logic remains the same this just maintains an ordered list of intersections,
tracking in-out points, to avoid re-computing every row,
this means sorting is only done once when out of order segments are found,
the segments only need to be re-ordered if they cross each other.
Speedup isn't linear, test with full-screen complex lasso gave 11x speedup.
Totally WIP.
Started with copies of legacy routines, modified to use the new shaders & batch cache. Not all features are implemented; this is why we keep legacy viewport around during development!
Do this for the new dependency graph: was missing handle of OB_UPDATE_TIME in tag update.
Hopefully it's all correct still.
Old dependency graph needs work, but i'm tempting to call it unsupported and move on
to 2.8 branch.
Several ideas here:
- Optimize calculation of near_{x,y,z} in a way that does not require
3 if() statements per update, which avoids negative effect of wrong
branch prediction.
- Optimization of direction clamping for BVH.
- Optimization of point/direction transform.
Brings ~1.5% speedup again depending on a scene (unfortunately, this
speedup can't be sum across all previous commits because speedup of
each of the changes varies from scene to scene, but it still seems to
be nice solid speedup of few percent on Linux and bigger speedup was
reported on Windows).
Once again ,thanks Maxym for inspiration!
Still TODO: We have multiple places where we need to calculate near
x,y,z indices in BVH, for now it's only done for main BVH traversal.

Similar to the previous commit, avoid negative effect of bad branch prediction.

Initialization order of global stats and node types was not strictly

stats after that. This will zero out memory which was allocated from

Material linking might and does change the way how drawObject is calculated

easily.

Previously you had to click the name or icon of an item to select the object (or whatever) and on empty space within the row to set outliner selection.

Attribute names can still be of variable length, as long as the average length does not exceed AVG_VERTEX_ATTRIB_NAME_LEN. Since this includes unused attributes (length = 0) the current avg of 5 might even be too high.
Seems to be a bug in original implementation of a830280: code was always
using tangent space instead of UV map because it had the same name. Now
prefer UVMap over tangent because this is how Cycles works. At least it's
closer to.
Not sure it the save+reload issue is still relevant after this fix, that
needs to be double-checked.
Thanks @dfelinto for looking into the report and simplifying the case.
Should be included into 2.78a.
This allows appending of an entire scene from another blend file into this one,

Column flow layout was abuse ui_item_fit in a weird way, which was
broken for last column items.
Now rather use own code, which basically spread available width as

New functions activate & deactivate immediate mode. Call these when switching context and the internal VAO will be handled properly. VAOs are one of the few things *not* shared between OpenGL contexts.

This gives about 5% speedup on AVX2 kernels (other kernels still
have SSE disabled for math operations) and this solves the slowdown
of koro scene mention in the previous commit.
The title says it all actually. This commit also contains
changes to pass float3 as const reference in affected functions.
This should make MSVC happier without breaking OpenCL because it's
only done in areas which are ifdef-ed for non-OpenCL.
Another patch based on inspiration from Maxym Dmytrychenko, thanks!
This commit basically vectorizes existing code using AVX2 instructions
(without modifying algorithm itself). This gives quite nice speedups:
BMW: -8%
Classroom: -5%
Cat: -5%
Koro: +1%
Barcelona: -8%
That's on Linux machine, reported performance improvement on Windows
goes up to 20%.
Not currently sure why Koro is somewhat slower because it mainly uses
curve intersection tests, could be a time noise? Or osmething with the
cache utilization perhaps? In any case speedup in other scenes makes
me thinking that current state is acceptable for initial implementation.
This is again inspired by Maxym Dmytrychenko.
Based on existing ssef data type and to my knowledge it's also what happens in
Embree nowadays.
Inspired by Maxym Dmytrychenko and required for the upcoming triangle
intersection commit.
Hopefully the copyright message is correct.
When ray hits curve segment with SSS shader it was possible to have
uninitialized hit_P variable used for sampling.
Seems that was a reason of our headache of difference between AVX2
and SSE4 render results here, so now we can revert all the nasty
ifdef-ed inline policies.
Was multiplying matrices backward, so concatenation was broken. Fixed!
Also a way to mix legacy matrix stacks with the new library. Just during the transition! Anything within SUPPORT_LEGACY_MATRIX will go away after we switch to core profile.

Original fix in this area was not really complete (but was the safest at
the release time). Now all the crazy configurations of slots going out
of sync should be handled here.
For now, we merely add an option that sets CXXFLAGS envvar with
'--std=c++11' option.
There is no check done to ensure compatibility with the system
libraries, mainly because:
- It is all but trivial to get this information in a generic and
reliable way.
- Currently even cutting edge distributions may still distribute some c++98
libraries.
- With recent stdlibc++, both ABIs are supported together, which means
that incompatibilities are rather unlikely.
To summarize: if your system is recent and built with gcc-5.1 or more,
you should not experience too much troubles with c++11.
It was possible to have two viewports opened and start using Ctrl-0
to make different objects an active camera for the viewport. This
worked fine for viewports which had decoupled camera from the scene,
but if viewport was locked to scene camera it was possible to run into
situation when two different viewports are locked to scene camera but
had different v3d->camera pointers.
Apparently, the whole G.is_break is not used by OpenGL render, meaning
this flag will not be clear before running the operator. This was
causing missing file output after pressing Esc once for the rest of
Blender session.
Reworked logic in the few places that still called this. Deleted the "GLSL not supported" fallbacks.

Built-in shaders now use uniforms instead of legacy built-in matrices. So far I only hooked this up for new immediate mode.
We use the same matrix naming convention as OpenGL, but without the gl_ prefix, e.g. gl_ModelView becomes ModelView.
Right now it can skip the new matrix stack and use the legacy built-in matrices app-side. This will help us transition gradually from glMatrix functions to gpuMatrix functions.
Still some work to do in gpuBindMatrices. See TODO comments in gpu_matrix.c for specifics.
@zeauro reported this issue:
texture2DRect needs the ARB_texture_rectangle extension.
But isn't that an OpenGL 2.1 feature and should be part of GLSL 1.2+?
This should fix it, and future shaders should do something similar.
We were checking for number of tasks from given pool already active, and
then atomically increasing it if allowed - this is not correct, number
could be increased by another thread between check and atomic op!
Atomic primitives are nice, but you must be very careful with *how* you
use them... Now we atomically increase counter, check result, and if we
end up over max value, abort and decrease counter again.
Spotted by Sergey, thanks!
Got rid of GLU and some matrix manipulation. Everything is shader driven now, drawn with point sprites.

Since the collision modifier cannot be disabled, it causes a constant
hit on the viewport animation playback FPS. Most of this overhead can
be automatically removed in the case when the collider is static.
The updates are only skipped when the collider was stationary during
the preceding update as well, so the state is stored in a field.
Knowing that the collider is static can also be used to disable similar

@dfelinto reported crash when setting grid subdivisions too low.
Code was setting color twice and Gawain was catching this. Fix is to only set regular grid color when we have regular grid lines to draw. Then emphasized grid lines are free to set their own color further down.
Previously if the rendering is much faster than saving (for example,
when transcoding stuff via VSE) it was possible to have 100s of frames
in memory.
This isn't ideal because of limited amount of RAM, so need to have
some sort of limit. This is exactly what is implemented in this commit.
By the design of task scheduler it was possible that tasks from somewhere
in the middle of scheduled list will be handled first.
For example, one thread might be iterating over the scheduled list and
ignore tasks because there is other thread is working on task from the
same pool. However, if that other thread finishes task before iteration
is over current thread will pick up task from somewhere in in the middle
of the list.
This isn't a problem in general case, but for movie rendering we do need
to have strict order of frames.
This commit lands the core backend of the Custom Manipulators project onto the blender2.8 branch. It is a generic backend for managinig interactive on-screen controls that can be integrated into any 2D or 3D edito. It's also already integrated into the window-manager and editor code where needed.
NOTE: The changes here should not be visible for users at all. It's really just a back-end patch. Neither does this include any RNA or Python integration.
Of course, there's still lots of work ahead for custom manipulators, but this is a big milestone. WIP code that actually uses this backend can be found in the 'custom-manipulators' branch (previously called 'wiggly-widgets').

This allows appending of an entire scene from another blend file into
this one, even when that blend file contains proxified armatures.
Since the proxified object needs to be linked (not local), this will
only work when the "Localize all" checkbox is disabled. The appended
proxy object should also not be referenced from anything in a library
(for example in a constraint). Referencing it from the appended data
should be fine.

We can't prevent users from using this branch, so I'd say it's reasonable to be a bit careful about what we store to files. In this concrete case we were storing a bit-flag for temporary use (only during early viewport transition) in a bit-field that's saved in files. Doing so would mean we either can't reuse this bit later or we risk breaking files (admittedly, likely in a pretty minor way). Moved the bit-flag to a new bit-field which can be removed later.
Makes it easier to enable it and avoids jumping of the panel when activating/deactivating it (because some panels disappear then). Also changed how panel title is drawn to make it behave like other panels.
We will keep the old system working as long as we can. At the moment even the visibility flags we are getting from the old system. That will continue like this until we have decided on the new UI
The initial idea was to use Ctrl+E to interpolate stroke because this is
similar to Pose breakdown, but the Ctrl+E keymap is used to inverse
grease pencil sculpt effect.

A new option (set in the properties region) allows the user to pick the
"new viewport" for the rendering (in the UI: Modern Viewport).
For now we have a semi-blank file (view3d_draw.c) that can starts to take
over the drawing pipeline.
I can't guarantee we will be able to keep both drawing systems working
through the entire 2.8 development, but it should do for now.
also, we can use branches for some of the viewport development, but it's
better to keep things in 2.8 whenever we can, so people can test it.
New recursive iteration over IDs in BKE_library_foreach_ID_link() was
broken by the infamous nodetree case. We cannot really recusively call
this function in that case, so better to deffer handling of
non-datablock NodeTrees as if real IDs here.
Also fixed initial ID not being stored as handled, in rare cases this
could also lead to infinite looping.

Mostly this is making inlining match CUDA 7.5 in a few performance critical
places. The end result is that performance is now better than before, possibly
due to less register spilling or other CUDA 8.0 compiler improvements.

This change makes it so that when the sequences within a Scene strip are

This is mainly either a copy-paste error (when new file was

1. When adding one pixel border to UV islands prefer grid directions.
This is more logical as it means neighbor pixels will commonly
share a border, opposed to just corners.
2. Don't subtract 0.5 when converting float UVs to int in computing
adjacency across a UV seam. Pixels cover a square with corners
at int positions and adding/subtracting 0.5 is only for dealing
with the center point of a pixel.
3. Use the neighbour_pixel field from the correct pixel, and check
it's not back to the origin point.
4. In the connected UV case, ensure that the returned index actually
refers to a valid active pixel.

The light sampling functions calculate light sampling PDF for the case that the light has been randomly selected out of all lights.
However, since BPT handles lamps and meshlights separately, this isn't the case. So, to avoid a wrong result, the code just included the 0.5 factor in the throughput.
In theory, however, the correction should be made to the sampling probability, which needs to be doubled. Now, for the regular calculation, that's no real difference since the throughput is divided by the pdf.
However, it does matter for the MIS calculation - it's unbiased both ways, but including the factor in the PDF instead of the throughput should give slightly better results.

mul_m4_m4m4(R, A, B) gives us R = AB in general. Existing code assumed the worst, that A and B both alias the output R. For safety it makes internal copies of A and B before calculating & writing R.
This is the least common case. Usually all 3 matrices differ. Often we see M = AM or M = MB, but never M = MM.
With this revision mul_m4_m4m4 is called in exactly the same way but copies inputs only when needed. If you know the inputs are independent of the output use the "uniq" variant to skip the saftety checks.

It's now possible to change the shortcut for invoking the eyedropper while hovering a button (E by default). Also removed the keymap editor entry for the modal eyedropper keymap, it's now automatically appended to the eyedropper shortcut.
This patch changes a couple of things in the video output encoding.
{F362527}
- Clearer separation between container and codec. No more "format", as this is
too ambiguous. As a result, codecs were removed from the container list.
- Added FFmpeg speed presets, so the user can choosen from the range "Very
slow" to "Ultra fast". By default no preset is used.
- Added Constant Rate Factor (CRF) mode, which allows changing the bit-rate
depending on the desired quality and the input. This generally produces the
best quality videos, at the expense of not knowing the exact bit-rate and
file size.
- Added optional maximum of non-B-frames between B-frames (`max_b_frames`).
- Presets were adjusted for these changes, and new presets added. One of the
new presets is [recommended](https://trac.ffmpeg.org/wiki/Encode/VFX#H.264)
for reviewing videos, as it allows players to scrub through it easily. Might
be nice in weeklies. This preset also requires control over the
`max_b_frames` setting.
GUI-only changes:
- Renamed "MPEG" in the output file format menu with "FFmpeg", as this is more
accurate. After all, FFmpeg is used when this option is chosen, which can
also output non-MPEG files.
- Certain parts of the GUI are disabled when not in use:
- bit rate options are not used when a constant rate factor is given.
- audio bitrate & volume are not used when no audio is exported.
Note that I did not touch `BKE_ffmpeg_preset_set()`. There are currently two
preset systems for FFmpeg (`BKE_ffmpeg_preset_set()` and the Python preset
system). Before we do more work on `BKE_ffmpeg_preset_set()`, I think it's a
good idea to determine whether we want to keep it at all.
After this patch has been accepted, I'd be happy to go through the code and
remove any then-obsolete bits, such as the handling of "XVID" as a container
format.

culling. Since Cycles itself doesn't ignore them (nor does Blender
Internal), they should be visible.
Steps to reproduce:
* Go to modifier context in properties editor
* Add modifier, collapse it
* Press down LMB over collapse button of modifier, hold it
* Drag over pin-icon in properties editor (to keep fixed data-block displayed)
* Drag outside of window bounds (should crash)
Also could've solved by getting space data from callback arguments instead of context, but this fix is much nicer (though not totally un-risky).
Is actually a redundant cast since Blender uses -funsigned-char, however I think it's fine to be explicit about it in new code so cast is required to make compiler happy. Am not a fan of -funsigned-char anyway...

There might be some extra missing points here, but it's all rather
a TODO than a real bug and can be tweaked further once issues are
actually discovered.
We raised the minimum to GL 2.1 in Blender 2.77, and dropped support for older GPUs (pre-2012 Intel mostly). On Windows you get a popup message, but on Mac we simply crashed. Every Mac has a builtin software renderer for GL 2.1 so let's use that when the GPU is not capable!
Run blender --debug-gpu to see version detection & software fallback.
Quick fix for now, need to unlock studio here as well.
Proper fix would be to modify API a bit and pass flags which will
prevent expand called on bmain perhaps. But this we should discuss
a bit,
We were calling BLI_remlink and then BLI_insertlinkbefore/after quite often. BLI_listbase_link_move simplifies code a bit and makes it easier to follow. It also returns if link position has changed which can be used to avoid unnecessary updates.
Added it to a number of list reorder operators for now and made use of return value. Behavior shouldn't be changed.
Also some minor cleanup.
Was spawning error popup each time user tried to move a stroke higher or lower than the list allowed. We don't do that anywhere else and it's not really useful info for the user. So rather not bother her.
Idea here is to select the lowest isolation level that wont compromise quality.
By using the lowest level we save memory and processing time. This will also
help avoid precision issues that have been showing up from using the highest
level (T49179, T49257).
This is a pretty simple heuristic that gives ok results. There's more we could
do here, such as filtering for vertices/edges adjacent geometric features that
need isolation instead of checking them all, but the logic there could get a
bit involved.
There's potential for slight popping of edges during animation if the dice
rate is low, but I don't think this should be a problem since low dice rates
really shouldn't be used in animation anyways.

Crashes occured immediately when clicking on "OpenGL render image" because there was only a task pool created previously when it was an animation. Solved it by introducing a variable is_animation to the openglrender and omitting the task_pool call when it's no animation.

Renamed some functions for consistency.
New features:
Create a Batch with immediate mode! Just use immBeginBatch instead of immBegin. You can keep the result and draw it as many times as you like. This partially replaces the need for display lists.
Copy a VertexFormat, and create a VertexBuffer using an existing format.
Resize a VertexBuffer to a different number of vertices. (can only resize BEFORE using it to draw)
Was already done for immediate mode, but rearranged code to make a clean separation. Cleaned up #includes for code that uses this feature.
Added same for batched rendering.
Follow-up to rBddb1d5648dbd
API is nearly complete but untested.
1) create batch with vertex buffer & optional index buffer
2) choose shader program
3) draw!
It was annoyingly slow to do roundtrip from byte OpenGL render to
float render result and back to byte image format (which is used
in 99% of cases for the OpenGL previews),
Now we use render result's rect32 to store render result which is
already supposed to be in the display space.
Gives about 30% speed improvement for OpenGL previews here.
Previously converting from linear space to SRGB was doing rather
slow inverted 1D lookup. Adding explicit inverse LUT gives 20%
speedup of OpenGL render.
Next question is: why do we even bother with sRGB conversion here,
OpenGL is already in the proper space so in theory we can avoid
quite some color space conversions. In any case, having this case
optimized in nice anyway.
New features:
1) Release target that checks for both cuda 7.5 and 8 with WITH_CYCLES_CUDA_BINARIES=ON and CYCLES_CUDA_BINARIES_ARCH=sm_20;sm_21;sm_30;sm_35;sm_37;sm_50;sm_52;sm_60;sm_61 options set.
2) Option to switch between x86 and x64 builds, the default remains (auto detect the architecture) but can be overridden.

- Follows XDG specification more closely,

- Prevents unexpected sizes of config folder, makes disk space used in more
predictable for users way.
- Allows to share kernels across multiple Blender versions,
which makes it easier debugging at the times close to release.
- "Copy Previous Settings" operator will no longer be copying possibly
gigabytes of cached kernels, which used to lead to really nast disk usage
and annoying delays of copying settings.
- In the future we can have some smart logic to clear old unused cached

Using ones complement for detecting if transform has been applied was confusing

Also added a few transforms where they were missing, mostly affecting baking

Now the factor works similar to other Blender areas to make the factor
more consistent for artists. The value 0% means equal to original
stroke, 100% equal to final stroke (50% means half way). Any value below
0% or greater than 100% create an overshoot of the stroke.
The existing code uses the input value count of the first channel

Most of the time, Lamps in Cycles are just a constant emission closure, no texturing etc. Therefore, running a full shader evaluation is wasteful.
To avoid that, Cycles now detects these constant emission shaders and stores their value in the lamp data along with a flag in the shader.
Then, at runtime, if this flag is set, the lamp code just uses this value and only runs the full shader evaluation if it is neccessary.
In scenes with a lot of lamps and with "Sample all direct/indirect" enabled, this saves up to 20% of rendering time in my tests.

The two SVM nodes added with e7ea1ae78c caused a slowdown on AMD cards when rendering with OpenCL, whether displacement was used or not.

When drawing with Grease Pencil "continous drawing" for a long time
(i.e. basically, drawing a very large number of strokes), it could be
possible to cause lower-specced machines to run out of RAM and start
swapping. This was because there was no limit on the number of undo
states that the GP undo code was storing; since the undo states grow
exponentially on each stroke (i.e. each stroke results in another undo
state which contains all the existing strokes AND the newest stroke), this
could cause issues when taken to the extreme.
See commit's comments for details, but this boils down to: do not try to use
purely runtime cache data as a 'real' ID pointer in readcode, it's likely
doomed to fail in some cases, and is bad practice in any case!
Thix fix implies dupliweight's object will be invalid until first scene update

immBegin requires us to know how many vertices will be drawn. Most times this is fine, but sometimes it can be tricky. Do we make the effort to count everything in one pass, then draw it in a second?

After poking around a lot it seems Droid Sans was used during 2.7x series.
(or at least difference between using this font and comparing to previous
splash screens gives none visible difference).
There were two inconsistencies in how 'save image' op initiated its settings:
* It would always use ImBuf->planes value.
* It would always use Image views settings.
Both of those settings should come from scene->r.im_format (as everything else)
when saving render/compo result...
Object coordinates can now be used in the displacement shader and will give
correct results, where as before bump mapping was calculated from the displace
positions and resulted in incorrect shading.
This works by evaluating the shader in two parts, first bump then surface, and
setting the shader state to match what it would be if the surface was
undisplaced for the bump shader evaluation. Currently only `P` is set as if
undisplaced, but other shader variables could be set as well, such as `I` or
`time`. Since these aren't set to anything meaningful for displacement I left
them out of this patch, we can decide what to do with them separately.

So now, localize funcs do not increment any usercount anymore (since matching BKE_free... ones do

When undo in UV/Image editor and press ESC key, there was segment fault
in Toolsettings because the reference was missing. Now the toolsetting
is loaded from context and not from local operator data.
Was kinda split in two different places (one allowed to modify given path to always get a valid one,
the other only checking for validity of given path), not nice - and broken in asset branch case.
So rather extended a bit FileList->checkdirf to handle both cases (modifying and non-modifying path).
We usually don't silence migh-be-uninitialized warning (which is the only
thing which could explain setting matrix to all zeroes) so we can catch
such errors when using tools like Valgrind.
I don't get warning here and the initializer was wrong, so removing it.
If it-s _REALLY_ needed please do a proper initialization.
Previously, they were in a column alongside the list, but because the lists were
rarely that long, there would always be a large gap left below the list.
This was because the poll callback was checking for the presence of an active layer.
If you just create an empty datablock and try to paste, nothing would happen.
However, this check was kindof redundant anyway, as the operator would add a layer for
you if it didn't find one.
(Later this calculation should be moved into the iteration macro instead, since
it only needs to be applied once per layer along with the diff_mat calculation)
A common problem encountered by artists was that they would accidentally move
the 3D cursor while drawing, causing their strokes to end up in weird places in
3D space when viewing the drawing again from other perspectives.
This operator helps fix up this mess by taking the selected strokes, projecting them
to screenspace, and then back to 3D space again. As a result, it should be as if
you had directly drawn the whole thing again, but from the current viewpoint instead.
Unfortunately, if there was originally some depth information present (i.e. you already
started reshaping the sketch in 3D), then that will get lost during this process.
But so far, my tests indicate that this seems to work well enough.
After the GP v2 changes, it wasn't possible to easily set the thickness of strokes
if you didn't know about the pie menus already. This just exposes the same set of
settings.
Parenting options are not visible there (i.e. they're only for the 3D view),
so reserving space that isn't going to be used in those editors doesn't really
make much sense. Furthermore, those property regions are often quite narrow
too, so it doesn't help too much to keep these settings so narrow there.
transparency.
The issue is that we are rendering to a 0..1 clamped sRGB buffer with
unpremultiplied alpha, where the correct thing to do would be to render
to an unclamped linear premultiplied alpha buffer. Then we would just
make fire purely emissive without affecting the alpha channel at all,
but that doesn't work here.
So for now, draw fire and smoke separately using different shaders and
blend modes, like it used to before the smoke programs were rewritten
(see rB0372b642).
Meshes with Cycles subdivision were being transformed to world space leading to
normals to sometimes be calculated in that space, while they should be in
object space. Also caused dicing to happen at the wrong rate for scaled meshes.
Application code can pass ubytes, Gawain converts to float vec4 expected by shader.
For now the conversion is simple linear. We can add sRGB support later if needed.
General reshuffling of defines and spacing/brace usage for consistency.
In particular:
* When defining types, don't mix pointers and non-pointer types on same line
to avoid confusion
* As much as possible, have all defines at the top of each block instead of
scattered haphazardly throughout the code
Users have been getting a bit confused by the way things are worded/arranged in
the UI. This patch makes a few changes to the UI to make it more clear how to
use subdivision:
- make Subdivide UVs option inactive when adaptive subdivision is enabled as UV
subdivision is currently unsupported
- add "px" to dicing rates in the Geometry Panel
- display the final dicing rate in the modifier
- reworded "Dicing Rate" in the modifier to "Dicing Scale" to make more clear
that this is a multiplier for the scene dicing rate and added a note the the
tooltip pointing the user to that setting in the Geometry Panel

Assigning NULL to scopes' data pointer in 'non-UI readfile' context was terribly wrong for sure,
if we'd really want to reset them here we should freed them first.
But we can rather just ignore them here, those are purely runtime data managed by image editor,
no need to touch them here.
Significant rewrite with some improvements.
Maintain visual hierarchy of the grid:
- emphasized lines draw atop normal lines
- axes draw atop all lines (same as before)
Draw axes only once, not twice.
Return early if nothing to draw.
Single draw call for the default case (grid floor with X and Y axes).
Z axis needs a second draw call because it uses 3D coordinates.

* Stroke editing functions should be in gpencil_edit.c not gpencil_data.c
(the latter is only for handling "CRUD" operations on things like
layers, brushes, and palettes)
* Deduplicate the GP_STROKE_BUFFER_MAX define
Added a way to select all the currently visible strokes that use the same
color as the selected stroke. This can be accessed via the Select Grouped (Shift-G)
operator as an alternative to selecting by layer.
This commit adds optional "pressure" and "strength" arguments to the
stroke.points.add() method. These are given default values of 1.0,
so that old scripts can be ported over to the new API with less effort
while reducing confusion about why auto generated strokes won't appear.
Also reduced number of matrix ops by generating final positions directly.
Also removed a display list (deprecated in modern GL).
Tried to reuse sinval & cosval tables but those values are skewed (last value repeats first value, middle values are squished to compensate). Went with sinf & cosf instead.
Part of T49042
The idea of the change is to avoid queue growing too long
and handle all the operations as quick as possible.
Gives about 3% speedup on one of the barber shots here.
Now we pass streams to Alembic instead of passing the filename string.
That way we can open the stream ourselves with the proper unicode
encoding.
Note that this only applies to Ogawa archive, as HDF5 does not support

Changes from microdisplacement work broke previous support for subdivision
meshes, sometimes leading to crashes; this makes things work again. Files
that contain "patch" nodes will need to be updated to use meshes instead, as
specifying patches was both inefficient and completely unsupported by the new
subdivision code.
Auto-scale is expected to work just fine now.
Only thing changed now is the pivot point for the scale: it is now
the same as rotation pivot, so scaling happens around weighted median
of the translation tracks. This seems to be what is actually required
for the VFX workflow.
Previously, this extension used the translation compensated image centre
as reference point for rotation measurement and compensation. During
user tests, it turned out that this setup tends to give poor results
with very simple track configurations.
This can be improved by useiing the weighted average of the location
tracks for each frame as pivot point. But there is a technical problem:
the existing public API functions do not allow to pass the pivot point
for each frame alongside with the stabilisation data. Thus this
change implements a trick to package a compensation shift into
the translation offset, so the rotation can be performed around
a fixed point (center of frame). The compensation shift will then shift
the image as if it had been rotated around the desired pivot point.
It is common in blender to use 1-based counting for
frame sequences (while 0-based is allowed). Thus
initializing to use frame 1 as reference for stabilization
is likely to produce smooth start values in most cases
values > 1 will zoom in and values < 1 zoom out
Rationale: the changed orientation is more natural
from a user POV and doing it this way is also more
consistent with the calculation of the other
target_* parameters.
Compatibility: This will break *.blend files saved
with the previous version of this patch from the
last days (test period). It will *not* break any
old/migrated files: Previously, the DNA field "scale"
was only used to cache autoscale. Only with the
Stabilisator rework, "scale" becomes a first class
persistent DNA field. There is migration code to
init this field to 1.0
We should treat all three "target" ("expected") parameters in a similar way:
The "influence" control should only work on the measurement part of stabilisation,
i.e. it should only control the automatic part of stabilisation, while
the target parameters are deliberately set by the user and thus should
even be in effect when the automatic stabilsation is turned down.
It used to be so for location and rotation, but for the scale part,
I re-used the existing code for autoscale, which also had the scale influence
work on the autoscale factor. This was sensible in the old version,
since scale_influence was the only way to control the result. But now,
the user has always total control trough the "target_*" parameters
and thus we should prefer to treat all similar.
The little grabby handle in the corner of an area. Now uses 1 draw call
instead of 6.
Also one version of the (+) icon to show a hidden region. Why do we
have multiple versions of this?
Fixed a harmless signed/unsigned error.
Fixed a GL state error that prematurely disabled blending.
Added imm_draw_filled_circle function, which can be used for drawing
other widgets.
Work toward T49042 and T49043
The if branches were reordered when the original patch was
committed, which broke the implicit non-NULL guarantee on link.
To prevent re-occurrence, add a couple of unit tests.
For best results use the latest 3Dconnexion driver. But latest is only
supported on Mac OS 10.9+. We go all the way back to Mac OS 10.6 so
have to deal with older driver versions.
See the original dlclose line for my faulty assumption. Waiting to
unload the driver later fixes the crash. Newer drivers don’t seem to
have this issue.
Also removed WITH_INPUT_NDOF guards as NDOFManager.h takes care of

Scanned Blender code for commonly used glVertex, glColor functions.
Implemented immVertex, immAttrib versions of these to ease transition
away from legacy OpenGL.
Keeping unused gla2D code because it might be useful, or inspire
something useful, for Blender 2.8 development.
Also removed an old Mac driver bug workaround. Disabled this before the
2.77 release and nobody has complained.
Was a concurrent access of pointcache from both particle system and UI (time space).
Pointcache not being threadsafe is really an issue to be addressed for its next version,
for now simply locking spacetime (like we already do with 3DView), not ideal fix
but it's working and safe for release.
This code obviously should also use the cache_fields flag variable,
like the code for reading the lowres data in the same function.
This is because fluid_fields actually represents the old state before
smoke was reallocated to match cache_fields read from the file, and if
it has some fields enabled that aren't allocated any more, it crashes.
This also fixes a reverse glitch: when a file was loaded with
the current frame in the middle of a baked smoke+fire simulation,
smoke appeared immediately, but the fire didn't until the frame
was changed. The reason is the same: after file load no fields
are initially allocated and thus fluid_fields is 0.
ccgDM_drawMappedFacesMat was missig a smooth shade model restore, some other

ifdef’ing out defines in DNA/RNA is not a good idea, was breaking alternative keymaps loading

Errors are caught & reported by our GL debug callback. This gives us way more useful information than sporadic calls to glGetError.

Still used in rna_Image_gl_load because it passes unvalidated input to OpenGL functions.
Still used in gpu_state_print_fl_ex as an exception handling hack -- will rewrite this soon.
The optimism embodied by this commit will not prevent OpenGL errors. We need to analyze what would cause GL to fail at certain points and proactively intercept these failures. Or guarantee they can't happen.

This aligns the behaviour of the file selection with the other

Also set a default file name for the Alembic export operator in case the

This function is only really secure in a very limited amount of cases,

So not worth bothering with it, just always use BLI_strncpy instead.

editor does not show NDOF mappings.
DNA does not change.
On my Mac the compiled binary is 42KB smaller after this change. It
runs fine WITH_INPUT_NDOF on or off.
These latter can cause MSVC debug asserts if the array is empty. With C++11
we'll be able to do this for std::vector later. This hopefully fixes an assert
in the Cycles subdivision code.
Basically title says it all.
The goal is to make platform maintenance easier, so you don't have
to constantly scroll back and forth looking for if() branches to
check which exact platform you're currently working on.
Ideally we also would move option defaults to a platform files,
but that i'm not sure how to implement in a nice way yet.

If the ruler is saved, a new color was created for each ruler. With the

Similar to their 2D counterparts, but are not combined because of

It's becoming annoying to have public API dependent on build type
and everything. Let's just always have API defined and do stubs
in the function implementation instead.
Current implementation more or less indiscriminately links physics
objects to colliders and forces, ignoring precise details of layer
checks and collider groups. The new depsgraph seemed to lack some
such links at all. The relevant code in modifiers suffers from a
lot of duplication.
Different physics simulations use independent implementations of
collision and similar things, which results in a lot of variance:
* Cloth collides with objects on same or visible layer with dupli.
* Softbody collides with objects on same layer without dupli.
* Non-hair particles collide on same layer with dupli.
* Smoke uses same code as cloth, but needs different modifier.
* Dynamic paint "collides" with brushes on any layer without dupli.
Force fields with absorption also imply dependency on colliders:
* For most systems, colliders are selected from same layer as field.
* For non-hair particles, it uses the same exact set as the particles.
As a special quirk, smoke ignores smoke flow force fields; on the other
hand dependency on such field implies dependency on the smoke domain.
This introduces two utility functions each for old and new depsgraph
that are flexible enough to handle all these variations, and uses them
to handle particles, cloth, smoke, softbody and dynpaint.
One thing to watch out for is that depsgraph code shouldn't rely on
any properties that don't cause a graph rebuild when changed. This
was violated in the original code that was building force field links,
while taking zero field weights into account.
This change may cause new dependency cycles in cases where necessary
dependencies were missing, but may also remove cycles in situations
where unnecessary links were previously created. It's also now possible
to solve some cycles by switching to explicit groups, since they are
now properly taken into account for dependencies.

For now simply reshuffle option so they keep proper dependency flow.
Benefits:
- Has an ability to hide tracks lists to work with other sliders around.
Could be really handy to quickly get rid of lenghty lists.
- From a feedback seems to be fitting workflow better.
Things to doublecheck on:
- Feels a bit misordered: first you define whether one want to have
rotation stabilized, then have tracks, then scale options.
While this follows dependency flow (which is really good and which
we should not violate) it has weird feeling on whether things are
really where they have to be.
- Autoscale controls visibility of max-scale, can we just make it
active/inactive instead?
- Autoscale replaces slider with label. Can it be disabled slider
instead to reduce visual jumping (disabled slider prevents user
input)
Hopefully we'll still want to have collapsable box after re-iterating
over this points, so we don't waste bits in DNA.

See this video for UI explanation and demonstration of usage
http://vimeo.com/blenderHack/stabilizerdemo
This proposal attempts to improve usability of Blender's image stabilization
feature for real-world footage esp. with moving and panning camera. It builds
upon the feature tracking to get a measurement of 2D image movement.
- Use a weighted average of movement contributions (instead of a median).
- Allow for rotation compensation and zoom (image scale) compensation.
- Allow to pick a different set of tracks for translation and for
rotation/zoom.
- Treat translation / rotation / zoom contributions systematically in a
similar way.
- Improve handling of partial tracking data with gaps and varying
start / end points.
- Have a user definable anchor frame and interpolate / extrapolate data to
avoid jumping back to "neutral" position when no tracking data is available.
- Support for travelling and panning shots by including an //intended//
position/rotation/zoom ("target position"). The idea is for these parameters
to be //animated// by the user, in order to supply an smooth, intended
camera movement. This way, we can keep the image content roughly in frame
even when moving completely away from the initial view.
A known shortcoming is that the pivot point for rotation compensation is set to
the translation compensated image center. This can produce spurious rotation on
travelling shots, which needs to be compensated manually (by animating the
target rotation parameter). There are several possible ways to address that
problem, yet all of them are considered beyond the scope of this improvement
proposal for now.
Own modifications:
- Restrict line length, it's really handy for split-view editing
- In motion tracking we prefer fully human-readable comments, meaning we
don't use doxygen with it's weird markup and comments are supposed to
start with capital and end with a full stop,
- Add explicit comparison of pointer to NULL.

Work toward T49043, with a side of client vertex arrays.
Not a straightforward port from glVertex to immVertex since Gawain needs

Fixed these not-so-great aspects of grid drawing:
- coarse grids would draw atop some lines from the finer grids
- visible axes would draw atop lines from coarse grid
- axes were drawn even if they weren't in view
- terrible misuse of vertex arrays
- each line issued its own draw call
New code draws each line exactly once. The entire grid is one draw call.
Bonus: I had to / got to learn how the units system works!
New value of 4MB should handle our needs without taking up too many GPU

Old value of 1KB was for observing what happens when the buffer fills up

When updating the max values under stiffness scaling, they clip at the normal stiffness values
as expected, however when updating stiffness values, you could set them higher than the max
values, and the max values weren't updated accordingly. As the stiffness scaling computes using
the absolute difference between the max values and the stiffness values, you got higher
stiffnesses in scaled areas even though your max is actually lower than the normal stiffness.
This diff fixes that behaviour, by updating the max values to be equal to the stiffness whenever
you set a higher stiffness than the max value.
Also, I have initialized the max values to the same as the stiffnesses, as they were previously
just set to zero, and caused the same problem described above.

Node tree update calls in the middle of a socket loop are dangerous, they can change sockets

New dependency graph puts materials to the graph in order to deal with animation

This solves issue when making mesh shared by multiple objects a single

Now we have the 4 component ones first (float4, byte4, half4) followed by the 1 component ones (float, byte, half).
Makes code a bit more consistent and also reduces code a bit when enabling half support on GPU in next commit.
This also exposed a typo in half CPU images for 3D textures, which wasn't used yet, but good to have that one fixed anyway.
Point cache read code contains checks designed to prevent it reading
stale data when the relevant simulation code should instead compute
the next frame from the previous one. However in some situations like
motion blur subframes the simulation can't possibly do it and just
exits. This causes completely incorrect motion blur at or after the
last cached frame.
To fix, add a parameter that tells the cache code whether it should
apply the checks and exit, or read what it can even if stale (true
means exactly same as old behavior).
Doing this in cache rather than clamping the frame number better in
the caller lets it handle the case of incomplete cache that stops
before the official last frame.

Using unit tests is a wrong way to control static behavior of the

better way to draw drop shadows, but that can wait!)
Part of T49043.
This is what I had in mind for D1753.
If you don’t specify a vertex’s color, it will use the color of the
previous vertex. Similar for all other attributes.
This matches the legacy behavior of glColor, glNormal, etc. *except* in
Gawain the first vertex of each immBegin must be fully specified. There
is no “current” color in the new system.
Should be simpler to use now.
Made vertex format structure private. New immVertexFormat() function
clears and returns the format. Devs can start with add_attrib(format...)
and not have to clear it first.
immBindProgram automatically packs the vertex format if needed.
Updated 3D cursor drawing to use new API.
Since the optimal values depend on the device used, this option doesn't make much sense in the XML.
Therefore, it's now specified via the command line, just like the device itself.
glBindAttribLocation does not take effect until the program is
re-linked. In other words I was doing it wrong!
New code gets attrib locations from program, then remembers the attrib
-> location mapping for subsequent draw calls.
The program and VertexFormat are not modified (makes threading and reuse
easier).
There are older ways to give OpenGL hints about buffer invalidation, but
glInvalidateBufferData does exactly what we want. Use this function when
OpenGL 4.3 is available (Windows and proprietary Linux drivers).

Changed messages to the actual GL_FRAMEBUFFER_XXX symbols. These are less friendly and more accurate. Can easily look up what an error means, unfiltered by what a Blender dev thinks it means.
Kept ES error codes around in case we support that one day. Just flip the #if or use a compile-time option.

The first character of the ID type was used to tag IDs for updates which
is weak since different IDs can have the same first character (for
example meshes, materials and metaballs), causing unnecessary updates of
unrelated IDs.
Now we use a unique index per ID type to tag for updates, unifying IDs
arrays indexing along the way.

Depth buffer values are used by the viewport pan and zoom code to
adjust response scaling factors between mouse and viewport movement.
Letting smoke write to the buffer confuses it and causes the camera
to get stuck and move very slowly inside smoke domains, because it
thinks it is very close to an object.
Use simple alternating colored lines instead of stippled overdraw.
Reimplement circ function to not use deprecated GLU (T49042). It also

immBindBuiltinProgram extends Gawain’s immBindProgram to use Blender’s

It uses imm prefix instead of GPU_ so people won’t be tempted to call

this function needs to be in the GPU lib.
Another issue with the modified particle motion blur fix: since
pre and post are used as validity markers, they must be set even
if there is no actual motion, like the original bool flags were.
Otherwise an object starting to move or stopping is interpreted
as having invalid blur data and hidden.
Wasn't copying back local view bytes to object after changing layer.
Steps to reproduce were:
* Split 3D view in default startup.blend
* Enter local view in one of the 3D views
* Move default cube to different layer *in the other 3D view* (the one that's not in local view)
* Try transforming object from 3D View that's in local view (should lag)
Displacement is now a per material setting, which means old files will have to

From source code history, it seems this behavior is a relic of a very
old limitation when the same object couldn't be both a Softbody and a
Collision object. In those times if somehow both modifiers were added
to an object, Softbody auto-disabled itself and buttons were hidden.
Now however there is no problem having both modifiers on an object,
so there is no point hiding the buttons. The same exact buttons are
available on the physics tab in any case.
As reported in T48928, From Dupli UV is not supported for grid
distribution, and running the normal code as usual simply produces
nonsense data, because fuv is used to hold orco instead of
interpolation factors for uv, and num is zero.
Since support won't be added in 2.78, just stop outputting nonsense.

There were two issues here. One is that the fix done originally for this
bug only checks for colliding with the same face as the single preceeding
hit. If the particle hits an edge or vertex of the collider, it in fact
hits two or more faces, so the loop ends up cycling between first two
of them and reaches the max collision limit.
The fix is to disable the collider for the sim step once a permeability
roll succeeds, by adding it to a skip list. Skipping just one face causes
some particles to bounce at odd angles in case of partial permeability.
The second problem was that the collider bounced back a small percentage
of particles, and the cause seemed to be that the code was set to flip
the velocity if the particle was just past the collider but still within
collision distance. Inverting both values causes a half permeable collider
to stop particles, so it seems that this if branch shouldn't bounce at all.

This changes actually lead to 2x slowdown. It's getting a bit annoying
because those are the changes to make pre-maxwell cards render with the
same speed.
The problem happens because smoke collides only with the surface of the
collider and uses incompressible fluid solver. This means that scaling
the collider tries to compress or decompress fluid within the volume of
the collider, which can't be handled by the simulation. Fast rotation
likely also causes transient scaling due to emulation of arcs by chords.
This can be fixed by finding compartments completely isolated by obstacles
from the rest of the domain, and forcing total divergence within each one
to be zero so that equations are solvable. Physical validity is somewhat
dubious, but without this the solver simply breaks down.
From the physics point of view, the effect of the correction should be
similar to opening a hole from every cell to another dimension that lets
an equal amount of air to pass through to balance the change in volume.

Initial report/patch by Alexander Gavrilov (@angavrilov), found more on the road.
Nice demo of why we should use libquery ID looper in read code too - but that's for another day
(also because read code needs to take care of some deprecated pointers sometimes)...
Hating all those not-so-real ID types... Here there were two causes for the issue:
1) Linked shapekey ID was made local twice (once from mesh's make local, once by itself).
Solved by not explicitely making shapekeys (nor any other non-linkable datatype) local.
2) Key->from 'back pointer' to its owner was messing 'still in used' detection of linked data
after localization. Fixed with a hack for now, thinking correct solution might actually
be to not consider this pointer at all in libquery ID looper, since it's nothing like
and actual usage of mesh/lattice/curve.
Again, shapekeys as ID is a joke, those should be mere struct, they have absolutely nothing to do in Main, period. :(
Point 2) still demonstrates the need for better handling of IDs dependencies though,
so far we only hit corner cases, but think there could also be valid cases generating those
'dependency cycles' between IDs (ID a using ID b which uses ID a), this will have to be addressed some day...
This makes no sense since user usually only has release build... And those noisy printings are
behind debug flag anyway, so really no reason to only print them out in debug build.

Note that there are still some lose ends here, since some type are not handled by id_copy

directly and indirectly, localization will fail.
Scene copying might be doable though (maybe with a simple new 'full shalow' mode to existing BKE_scene_copy?),
not sure about sounds and vfonts... Situations where this becomes an issue should be very rare corner cases anyway.
Turns out most BKE_foo_make_local datablock-specific functions are actually doing
exactly the same thing, only two currently need special additional operations
(object and brush ones). So added a BKE_id_make_local_generic instead
of copying same code over and over.
Also, changed a bit how make_local works in case we are localizing a whole library.
We need to do the 'remap' step (from old linked ID to new local one) in the second loop,
otherwise we miss some dependencies. This fixes main part of T48907.
Mainly the changes are related on establishing API to feed UV islands
to OpenSubdiv, so it will know all the connectivity information and
will be able to do proper interpolation.
Island calculation is currently rather slow, not sure how to make it
fast and not use lots of allocations.
Shouldn't be THAT bad, since this code is only runs once when creating
OSD mesh, and it's probably still faster than our orientation code.
Note that issue has several levels here actually, first one was metaball's materials
not being properly copied into new mesh (code was commented out because of some crash it
seems, made it a bit closer to mesh one and got no crash at all...).
Then, we were calling test_object_materials when ob->data is actually *not* new tmpmesh!
Will remove this call completely in next commit (to make it easier to bisect), I cannot see
any case where object would be assigned with newly generated tmpmesh in this func.
A bit work in progress, currently the following limitations:
- Texture shading only, Material shading will come later
- No UVs subdivision yet
- Always uses active UV and currently changing active UV will
not properly update the viewport.
Well, need to start somewhere :)
The flatten brush depended on accumulate being disabled,
Adding dynotopo support for accumulate caused problems for this tool (see T44390).
Enable for existing files.
- remove edge scaling, instead avoid checking intersections with connected edges.
- replace local line intersection functions with BLI_math
- center the projection for more precise calculation.
BKE_previewimg_copy() would simply copy PreviewImage's icon_id, without bothering about
ID one.
When we duplicate an ID, we want to reset its icon_id to zero (and regenerate it on-demand),
not keep same icon_id as original, so added new BKE_previewimg_id_copy helper to handle that.
This probably makes code somewhat slower, but we can't easily know
whether we can use a shortcut and only use directional lighting from
the scene.
Need some better integration between GPU and OpenSubdiv for that.

The warning was clear, the code not as much. The version check in place
here is quite convoluted and could be replaced by including VersionHelpers.h

This however did require that the CreateInstance call actually asked for
ITaskbarList3 and not ITaskBarlist . (You're not really allowed to assign
different interface types to each-other, a roundtrip through QueryInterface
is required there, we were violating spec here by asking for ITaskBarlist and
storing it in ITaskbarList3* )

This diff adds a 6th drawing mode to the Waveform Scope.
The new mode shows the RGB colour channels overlaid as a "Full colour" waveform.
The old "Red Green Blue" mode is renamed "Parade" which is the standard industry
term for RGB channels shown side-by-side.
This full colour style of waveform is very much more useful for colour grading than the
Parade mode and is the default waveform for many artists.

The issue was caused by SSS intersection code gathering all
intersections without check for duplicated ones. This caused
situations when same intersection will be recorded twice in
the case if triangle is shared by several BVH nodes.
Usually this is handled by checking intersection distance
after sorting intersections (in shadow_blocked for example)
but for SSS we don't do such sorting and using number of
intersections to calculate various things.
Didn't find anything smarter than to check intersection
distance in triangle_intersect_subsurface().
This solves render artifacts in the cost of 1.5% slowdown
of extreme case rendering (SSS object filling in whole
FullHD screen).

- In fresnel_dielectric, the differentials calculation sometimes divided by zero.
- When the normal map was (0.5, 0.5, 0.5), the code would try to normalize a zero vector. Now, it just uses the regular normal as a fallback.
- The approximate error function used in Beckmann sampling sometimes overflowed to inf while calculating r^16. The final value is 1 - 1/r^16, however,
so now it just returns 1 if the computation would overflow otherwise.
Also, this fixes a numerical issue where A would be inf.
Since later G is set to 1 if A is larger than 1.6, the code now checks the reciprocal of A for being smaller than 1/1.6 - same effect, but no inf involved.

While it's an extra option added to the interface which might not be

This is high enough memory saver in my opinion which might become

After reformulation of SSS indirect rays it became possible to
try accessing dimension higher than was pre-calculated on scene
preparation.
This is because we're traversing rays backwards, which means we
are using higher dimensions first now.
It was possible to miss bounces termination criteria in this functions,
mainly when max_hits was set to 0.
Made the check more robust in traversal functions (which should not
affect performance, it's an operation of same complexity AFAIK).
Also avoid doing ray-scene intersection from shadow_blocked when
limit of transparent bounces was already reached.
Applying cflags globally can be problematic especially with extern, intern libs.
Now flags from target named will be used when defined,
allowing for developers to define flags for modules they maintain.
Convention is CMAKE_CFLAGS_${UPPERCASE_TARGET_NAME}, (CXXFLAGS for C++).
eg: CMAKE_CFLAGS_BF_BLENDER, CMAKE_CFLAGS_MAKESDNA, CMAKE_CXXFLAGS_CYCLES_KERNEL
On Linux run `make help` for full list of names, MSVC shows these in the solution.
Accessing `bpy.app.binary_path_python does search, then swaps its getset with the string it finds.
This caused a freed pointer to be stored in bpy.app's dictionary.
Fix by using the same string for get/set access.
Recently the snap to edges has been changed to work with coordinates 2d. Thus, the lambda of the snap pointon on edge becomes different from the actual lambda in a 3d edge.
The solution to correct the lambda was this:
```
if (is_persp) {
const float fac = depth_a / (depth_a + depth_b);
lambda *= (1.0f + (fac - 0.5f) * (1.0f - lambda));
````
...
But the lambda was still not very accurate.
Now the function uses the `dist_squared_ray_to_seg_v3` to get the coordinate of the snap point on the edge. And then tests that point.
The accuracy returned to normal values.
from D2104: reference all repeated (and strange) equations (example: mul_m4_m4m4(pmat_local, pmat, obmat)) in the function `precalc_project.
This is useful for maintenance.
Current code changes the selection then then runs ED_armature_sync_selection

Reverting the commit. Not only it did not solve all the cases of proxy popping,
but also broke real cases with single proxy involved.
The snapping functions when performed in the perspective view,
have some problems in the threshold (a distortion) and in the clip plane (the normal is incorrect).
These problems can be only observed when making the snap to edges or to vertices (nearest to ray function).
This patch propose a totally different solution.
The idea is to project the edges of bvh nodes and test the 2d projection of the snap element.
For this it used the BLI_bvhtree_walk_dfs function.
It is important to pay particular attention also to the changes in `ED_transform_snap_object_project_view3d_ex`
- icon_id from ID and PreviewImage were not guaranteed to be in sync.
- PreviewImage one was not reset on file read.
- Through RNA e.g., it was possible to ensure an ID icon via its preview image,

of generating correct 'auto ID icon'.

Campbell, sorry. have to revert this for the time being.
We've missed some very important bits, such as:
- FFmpeg is usually linked against OpenJPEG
- OIIO needs OpenJPEG as well.
For FFmpeg issues we can either disable OpenJPEG there (since
we don't really use it), or bump FFmpeg to version 3.1.1 which
can use either of OpenJPEG 1.5 or 2.1.
For OIIO we do need OpenJPEG support (otherwise Cycles will
not be able to use j2k/j2c textures) and currently there is
NO solution to make OIIO working with OpenJPEG 2.1.
According to Matthias Fauconneau (aka mfv) Larry is working
on the patch to get OIIO work with OpenJPEG 2.1, but it'll
take some time still.
I've tried to look into support of some sort of build system
flag and do ifdefs, but it all becomes quite nasty, especially
with bundled OpenJPEG bumped to 2.1.
Surely such an update is something we'll have to apply to
but at this exact moment it causes quite some pain for all
developers.
Suggest to wait for until OIIO supports OpenJPEG 2.1 and then
go with the updates for real.
Idea looked good, but we have too much custom situations here (some half-fake-sub-ID
being copied with their 'owner', animdata, etc.), let's let datablock copy functions
handle that themselves.
Also allows to safely call BKE_id_expand_local from all copy functions now (only when
copying linked data).
ntree is once more time a PITA - actually, all sub-IDs that get copied together with the 'main' one are
(shapekey was workedaround, as was animdata/action issue, but nodes are more touchy).
For now, better not to touch that, needs careful check & rethink.
Reason is, typically those actions datablock usercounts have already been adjusted in BKE_animdata_copy()
(called by generic iddata copy function).
Think this needs to be reworked a bit too, there are way too much ways to copy animdata currently,
it's rather confusing. But not the goal here, so for now we'll live with the hack!
will be used by both make_local() and copy() datablock functions.
Note that this new func make 'extern' all IDs used by localized datablock,
not only refcounted ones as it used to be in each type's functions (with a few exceptions).
This way restrict can be used for CUDA and OpenCL as well.
From quick tests in areas i've been testing this it might give some
barely measurable %% of speedup, but it increases registers pressure.
So use of this qualifier is still really limited.
Using camel case for variables is something what didn't came from our original
code, but rather from third party libraries. Let's avoid those as much as possible.
Matches better naming of volume traversal files, where we've got
optimized versions of a single step of volume intersection and
traversal which will gather all volume intersections.
BVH traversal is not really that much a geometry and we've got
quite some traversals now. Makes sense to keep them separate in
the name of source structure clarity.
When an edge was collapsed, one of the vertices would be removed.
Edges attached to the deleted vertex wouldn't be considered for collapsing again,
making the outcome from collapsing edges depend on the edge-vertex order.
Use a hash to lookup the final vertex when collapsing edges, instead of skipping them.
The shader sync code used the anisotropic version of the Ashikhmin-Shirley closure for both
Anisotropic and Glossy BSDF, which caused a failed assert because the anisotropic closure
expects an addiitonal SVM node.
Mostly pass bmain and do not check for NULL key, keys' make_local is
suspiciously simple in fact, but think until those behave like real
full-featured IDs, it's doing enough!
* Alt-G, Alt-R, Alt-S --> These don't clear delta transforms by default anymore,
making it possible to use these to properly store a "rest" pose
* Alt-Shift-G, Alt-Shift-R, Alt-Shift-S --> These WILL clear both the normal
transform and the delta, should you need to do so.
At first thought it was own recent work, but think issue is there since ages actually...
Basically, id_make_local() would always localize mesh/curve/lattice shapekeys, even in case
obdata localization actually made a local copy instead of localizing original datablock.
This was causing shapekeys being localized twice, and other odd nasty effects.
libquery now passes an extra flag info to the callback, in case that specific
ID usage is considered as indirect.
In most cases, it's just set from ID_IS_LINKED_DATABLOCK() result on datablock owner,
but in proxy object case we also consider ob->data, materials and pose usages as indirect.
Does not fixes all issues yet, but should already make behavior with proxy object saner.
Now using modern features from libquery/libremap areas.
Provides same kind of fixes/improvements as for BKE_object_make_local() (see rBd1a4ae3f395a6).
Note: this enlightened broken case of proxy objects regarding make_local
(and also whole remapping, in fact). Will be fixed in near future.
Not really happy with this, could lead to a **lot** of callback executions...
But libquery foreach looper must go over **all** ID pointers,
otherwise remapping & co is broken!
A possible fix for future would be to have 'image slots' defined at root of poly/facetex layers,
and just a (short) index in each face/poly item - would also save a reasonable amount of memory...
Now using modern features from libquery/libremap areas.
Also, it should handle much better cases where localized ID was also indirectly used by non-refcounting users
(typical case: object used as modifier/constraint/whatever target from another linked object, previous
code would not take those into account and just localize original object instead of making a local copy.
Would result in local object used by linked one, which would be partially 'undone' on next file reload... Crappy behavior).
And it fixes some obvious errors too (nullifying all proxy pointers unconditionnaly,
some missing refcounted usages cases in extern_local_object(), etc.).
Totally stupid to not pass it, and then let (some) BKE_foo_make_local() use G.main!
Note: unused for now, much more refactoring still to come in make_local area!
Now test_object_materials only handles one object. New test_all_objects_materials
checks the whole bmain->object list for cases where it is actually needed.
Should avoid some useless looping over all objects!
Main issue was that BKE_libblock_relink_ex was pretty much ignoring all those...
Also, unlinking of objects was not handling correctly indirect-related flags.
Refactored code into helper functions to avoid too much duplicated code.
Toggling edit-node after joining objects is redundant as far as I can see -
(dates back to first revision).
Also caused all edges to be drawn w/ meshes, redundant undo step w/ curves.
`my_memcmp` didn't work properly comparing memory sizes not aligned to 4 bytes,
this worked while we used guarded-alloc (which always wrote a guard at the end of each allocation).
Since moving to lockfree allocator it could read uninitialized memory.
It also consistently performed ~10-30% worse then glibc's.
This is typically well optimized, no need to do ourselves.
Scaling a bone on the Y axis (for a stretch effect), wasn't supported by the IK solver.
Support this by solving as uniform scaled bones by matching the X,Z axis to the Y.
Requested by @pepeland, see D2088 for details.
This should allow us to avoid a lot of useless processing when iterating over the
whole main database (unlink/remap/usages checks/etc.).
Note that some ID types report they can use any type for now, due to
fuzzyness/indefined nature of some usages (like constraints/modifiers/game logic,
or ID pointer of nodes...). Maybe we could address this (like e.g. adding defines
in relevant headers to restrict ID types used by constraints, by modifiers, etc.).
But don’t think this is top priority for now.
This commit enables new unaligned BVH builder and traversal for scenes
with hair. This happens automatically, no need of manual control over
this.
There are some possible optimization still to happen here and there,
but overall there's already nice speedup:
Master Hair BVH
bunny.blend 8:06.54 5:57.14
victor.blend 16:07.44 15:37.35
Unfortunately, such more complexity is not really coming for free,
so there's some downsides, but those are within acceptable range:
Master Hair BVH
classroom.blend 5:31.79 5:35.11
barcelona.blend 4:38.58 4:44.51
Memory usage is also somewhat bigger for hairy scenes, but speed
benefit pays well for that. Additionally as was mentioned in one
of previous commits we can add an option to disable hair BVH and
have similar render time but have memory saving.

This commit implements traversal of unaligned BVH nodes.
QBVH traversal is fully SIMD optimized and calculates orientation
for all 4 children at a time, regular BVH might probably be optimized
a bit more.
This is a special builder type which is allowed to orient nodes to
strands direction, hence minimizing their surface area in comparison
with axis-aligned nodes. Such nodes are much more efficient for hair
rendering.
Implementation of BVH builder is based on Embree, and generally idea
there is to calculate axis-aligned SAH and oriented SAH and if SAH
of oriented node is smaller than axis-aligned SAH we create unaligned
node.
We store both aligned and unaligned nodes in the same tree (which
seems to be different from what Embree is doing) so we don't have
any any extra calculations needed to set up hair ray for BVH
traversal, hence avoiding any possible negative effect of this new
BVH nodes type.
This new builder is currently not in use, still need to make BVH
traversal code aware of unaligned nodes.
This seems to be straightforward way to support heterogeneous nodes
in the same tree.
There is some penalty related on 4gig limit of the address space now,
but here's are the thing:
Traversal code was already using ints to store final offset, so
there can't be regressions really.
This is a required commit to make it possible to encode both aligned
and unaligned nodes in the same array. Also, in the future we can use
this to get rid of __leaf_nodes array (which is a bit tricky to do since
trickery in pack_instances().
There are several internal changes for this:
First idea is to make __tri_verts to behave similar to __tri_storage,
meaning, __tri_verts array now contains all vertices of all triangles
instead of just mesh vertices. This saves some lookup when reading
triangle coordinates in functions like triangle_normal().
In order to make it efficient needed to store global triangle offset
somewhere. So no __tri_vindex.w contains a global triangle index which
can be used to read triangle vertices.
Additionally, the order of vertices in that array is aligned with
primitives from BVH. This is needed to keep cache as much coherent as
possible for BVH traversal. This causes some extra tricks needed to
fill the array in and deal with True Displacement but those trickery
is fully required to prevent noticeable slowdown.
Next idea was to use this __tri_verts instead of __tri_storage in
intersection code. Unfortunately, this is quite tricky to do without
noticeable speed loss. Mainly this loss is caused by extra lookup
happening to access vertex coordinate.
Fortunately, tricks here and there (i,e, some types changes to avoid
casts which are not really coming for free) reduces those losses to
an acceptable level. So now they are within couple of percent only,
On a positive site we've achieved:
- Few percent of memory save with triangle-only scenes. Actual save
in this case is close to size of all vertices.
On a more fine-subdivided scenes this benefit might become more
obvious.
- Huge memory save of hairy scenes. For example, on koro.blend
there is about 20% memory save. Similar figure for bunny.blend.
This memory save was the main goal of this commit to move forward
with Hair BVH which required more memory per BVH node. So while
this sounds exciting, this memory optimization will become invisible
by upcoming Hair BVH work.
But again on a positive side, we can add an option to NOT use Hair
BVH and then we'll have same-ish render times as we've got currently
but will have this 20% memory benefit on hairy scenes.
It was initially unsupported because initial idea of checking visibility
of all children was slowing scenes down a lot. Now the idea has changed
and we only perform visibility check of current node. This avoids huge
slowdown (from tests here it seems to be withing 1-2%, but more tests
would never hurt) and gives nice speedup of ray traversal for complex
scenes which utilized ray visibility.
Here's timing of koro.blend:
Without visibility check With visibility check
Original file 4min 20sec 4min 23sec
Camera rays only 1min 43 sec 55sec
Unfortunately, this doesn't come for free and requires extra data in
BVH node, which increases memory usage of BVH nodes by 15%. This we
can solve with some future trickery of avoiding __tri_storage created
for curve segments.
Those unwrap operators are a bit tricky, some are available from both 3DView and UVEditor, others only from 3DView...
Hacked around this by returning Mesh keymap for UV_OT ops for specific 3DView/MeshEditMode context.
This reverts commit 4fd78bb06f.
After further testing, it turns out that these options are less-broken than
I remember them being (and have been hearing about). Specifically, as long
as you disable all 3-axes of a transform component (i.e. all location, all
rotation, all scale) you're not likely to have problems, whereas if you only
disabled one axis (i.e. y-rotation), you may have problems in some cases.
So, restoring these to the UI.
Currently "long keyframes" are only useful for indicating where stationary
holds occur. If however you try to create a "moving hold" (where the values
are slightly different, but in terms of overall effect, it's still a hold)
then it could get tricky to keep track of where these occur.
Now it's possible to tag such keyframes (using the keyframe types - RKEY)
as being part of a moving hold. These will not only be drawn differently
from normal keyframes, but they will also result in a "long keyframe"
being drawn between each pair of them, just like if they had been completely
stationary instead.
Currently the theming/styling of these is a bit rough. They reuse the existing
theme colours for long keyframes.
* Added new operators to take the current transform value (loc/rot/scale or all 3)
and convert/apply that transform to a corresponding delta transform value. By default,
the transform value will be zeroed out again afterwards, so you don't end up with a
double transform.
* These operators can be found in the "Apply" menu (Ctrl-A)
* The "Animated Transforms to Deltas" (which does a similar job, except it adjusts all
existing animation data instead of the current transform) has also been moved to the
Apply menu (it was in the Transform menu instead)
A long requested feature has been to have objects appear in alphabetical order
in the animation editors, so that it is easier to find where they occur. This
commit implements support for this.
The main sticking point has been the performance impact of having this sorting
happening all the time (as the actual list of "bases" cannot be modified, as the
old depsgraph still needs random-looking unsorted order of objects for scheduling
updates). However, it recently occurred to me that perhaps by restricting it to
the one case where the ordering actually matters (i.e. when we're getting the channel
list for drawing all channels, vs operating on them), and adding a toggle to turn the
sorting off in heavy scenes when it might bog down things, that it will probably
be acceptable enough in general. Furthermore, if things get really bad, we can investigate
putting in place some sort of caching scheme for this too - though hopefully the
new depsgraph will make that unnecessary (i.e. it doesn't sort the bases directly anymore).
This commit introduces a scale factor setting for scaling all keyframe indicators
in the Dopesheet Editor up/down, in order to make them easier to select. It is perhaps
most useful for keyframe types which are usually indicated using smaller keyframes
(e.g. breakdown), which may get tricky to quickly select.
To make it easier to synchronise timing across multiple strips, if you add
markers locally to an action, these will show up in the NLA strip in the
NLA Editor. These markings can then be used to line up the start/end of
another strip, or even to make sure that the markers from two different
strips end up lining up.
By default, this is turned on, but it can be disabled (via the View menu)
if it adds too much visual noise.
This breaks any post-versionning (like IPO conversion, python handler, etc.).
rB961ebfa8c40b9909 mentions some Main being do_versionned several times (which is not desired for sure),
will try to reproduce again and find another fix.
Since SDNA was allocated for each undo step,
the new address meant it was considered different and included again.
Add an option not to duplicate the DNA string when calling DNA_sdna_from_data,
as well as avoiding a redundant copy, it writes the same address each time.
Idea is to replace hard-to-track (id->lib != NULL) 'is linked datablock' check everywhere in Blender
by a macro doing the same thing. This will allow to easily spot those checks in future, and more importantly,
to easily change it (see work done in asset-engine branch).
Note: did not touch to readfile.c, since there most of the time 'id->lib' check actually concerns the pointer,
and not a check whether ID is linked or not. Will have a closer look at it later.

Checking if faces exist was a bottleneck,
use a simpler version of this function for triangles.
Gives approx 1.6x overall speedup (when many edges are being collapsed).
When snapping to edge/vert, check the distance to the ray
instead of the screen-space pixel projection.
This also corrects the conversion of `dist_to_ray_sq` to `dist_px` which was being done incorrectly.
While this change was planned, it fixes T48791, caused by error in b01a56ee.
Two were actual bugs, though they existed only in unused code:
* In Freestyle it was unintentionally copying a scene rather than referencing it.
* In BLI_array_store_is_valid there was use of uninitialized memory.
As pointed by Brecht, previous fix in rB61b49de44940 was actually incomplete,
we could still hit float rounding issue and hence same value in more than one consecutive
items of element_sum.
New solution is a bit different, we remove the 'minimal weight' check, and rather simply
ignores an item when the sum of its normalized weight to previous item's sum does not add
anything. Shall be safe and 100% effective this time!
This patch is another step to achieve BI and it's Viewport consistency for cubemap textures.

This patch fixes shortcoming of D2046.
The original behavior without world_space_shading flag is that Texture node expects the reflected vector in view space. But with world_space_shading it should be in world space.
In attached file you will see a simple material setup and a node material analogue.
Simple material must have the same behavior regardless world_space_shading flag.

Environment lighting (aka ambient) is a key component of any renderer.
It's implemented like the Environment lighting of BI render for Approximate Gather mode. It support "Sky Color" and "White" Environment lighting modes.
It would be great if the user could see actual lighting conditions right in the Blender viewport instead of waiting for the renderer to complete the final image, exporting for external renderer or for a game engine.

This is in fact very hairy situation here... Objects are only refcounted by scenes,
any other usage is 'free', which means once all object instanciations are gone Blender
considers it can delete it.
There is a trap here though: indirect usages. Typically, we should never modify linked data
(because it is essencially useless, changes would be ignored and ost on next reload or
even undo/redo). This means indirect usages are not affected by default 'safe' remapping/unlinking.
For unlinking preceeding deletion however, this is not acceptable - we are likely to end with
a zero-user ID (aka deletable one) which is still actually used by other linked data.
Solution choosen here is double:
I) From 'user-space' (i.e. outliner, operators...), we check for cases where deleting datablocks
should not be allowed (indirect data or indirectly used data), and abort (with report) if needed.
II) From 'lower' level (BKE_library_remap and RNA), we also unlink from linked data,
which makes actual deletion possible and safe.
Note that with previous behavior (2.77 one), linked object would be deleted, including from linked data -
but then, once file is saved and reloaded, indirect usage would link back the deleted object,
without any instanciation in scene, which made it somehow virtual and unreachable...
With new behavior, this is no more possible, but on the other hand it means that in situations of dependency cycles
(two linked objects using each other), linked objects become impossible to delete (from user space).
Not sure what's best here, behavior with those corner cases of library linking is very poorly defined... :(
Also define single callback func typedef, cleaner this way!
Note: maybe we want to do that for the other callbacks too (data, etc.), but will be enough for now.
This is quite tricky situation which combined:
- Boolean modifier which accesses other object's derived mesh
(in fact, it's nothing to do with boolean modifier, any other
modifier which uses other's DM will have same bug).
- Dependency cycles in the scene which is rather russian-roulette
from the cycle solver point of view.
- Multiple instanced objects used as boolean operand.
With all this things combined boolean modifier was accessing operand's derived
mesh which was referencing data from Mesh datablock. The issue is that those
references are becoming invalid after EDBM_mesh_load().
This function already had code to make sure object itself does not end up with
dangling pointers from derived mesh. Make it now so no possible instanced objects
are left with dangling pointers.
And who said it's a good idea to reference something from derived mesh..
The Curves widget has buttons to zoom in on the curve. However the
click detection code doesn't take it into account, and at full zoom
in click on curve is detected very far from the actual visible curve.
Change it to compare the position to the actual line segments
in the UI coordinate space, i.e. with curve zoom applied.
This patch moves the PrintHardwareInfo() function in standalone only, not in embedded. Why? Because you can need this infos for debugging
purpose in "compiled" blender files but it was boring to have it displayed each time you launched embedded. So you can have this infos when you
click standalone or when you run your executable app from a console.

changes in BLI_kdopbvh:
- `BLI_bvhtree_find_nearest_to_ray` now takes is_ray_normalized and scale argument.
- `BLI_bvhtree_find_nearest_to_ray_angle` has been added (use for perspective view).
changes in BLI_bvhutils:

changes in math_geom:
- `dist_squared_ray_to_seg_v3` was added.
other changes:
- `do_ray_start_correction` is no longer necessary to snap to verts.
- the way in which the test of depth was done before is being simulated in callbacks.
Regression caused by own changes to make texture paint more efficient
from workflow point of view.
Now the idea is to use vertex color outside of paint mode, so we don't
break any compatibility here.
For simple cases bitmasks were OK, but didnt work for vert/edge, vert/edge tests.
Tag verts instead, makes logic easier to follow and gives minor speedup.
Make sure we don't perform any implicit address space conversion.
A bit annoying, but less intrusive approaches (like using temp private
variable in .cl kernel) do not work correct here.
Using generic address space will help from code side here, but will
be somewhat slower due to extra things happening as far as i know.
So the error seems to be in cubic_tangent_factor_circle_v3(),
which was introduced with D2001.
I've tweaked the most obvious culprit here - the epsilon factor.
It used to be 10^-7, but I've reduced it down to 10^-5 now,
and it's looking a lot more stable now :)
---------
BTW, about the derivation of the magic 0.390464 factor I briefly subbed back
as a workaround for this bug, see:
http://www.whizkidtech.redprince.net/bezier/circle/
It's probably some numeric precision issue, but until we figure out exactly what's
going wrong here, let's just revert back to the hardcoded value that was used here
successfully for years without issues.
Remapping indirect usage of IDs is forbidden from user space, this is calling for
nice nightmare with libraries handling (and undo crash, among other things).
Not sure why I was 'laxist' about indirect usage cases detection like that,
for now just consider any ID used by another linked datablock as indirect usage case!
Also, added some error/warning reports to Outliner's remap code.
The "W" channel will get a yellowish colour (i.e. a blend between the X/R and
Y/G axis colours), while the XYZ will behave as they do for other transforms.
The create drivers operator should not use the "Transform Channel" variable type
when driving one transform with another on the same object/bone. Otherwise, you
end up with a situation which technically results in a bit of a pseudo-dependency
cycle.
The Ctrl-Shift-C operator to add constraints between a pair of selected items,
for example, between two objects, or between two bones (in the same armature).
This commit makes it possible to use this operator to add a constraint where the
target is a bone from another object - e.g. to make a deform bone follow the control
bone in another armature, or to make an object use a bone as a tracking target.
Usage:
1) Ensure you are in Pose Mode, then select the bone to use as the target
2) Shift-Select the other object and/or the bone that's going to get the constraint
3) Ctrl-Shift-C
Problem was in fact slightly wider, File space was nearly not taking into account
library navigation case and its 'virtual' directoris, except in a few places.
Add a wrapper around BLI_is_dir that also check for lib paths, and used it in
ED_file_change_dir(), such that we now always check path is a
valid directory - in the filebrowser context, not filesytem context. ;)
As far as I can see, the second issue there was that the functions receive a pointer to a member variable of the
ShaderData, which is stored in global memory. However, this means that the pointer points to global memory as well,
therefore OpenCL requires the ccl_addr_space "keyword" in front of the pointer.
With this commit, the OpenCL kernels build on Linux with the Intel CPU OpenCL runtime - however, they already did
without the change and I don't have an AMD card, so I can't really test whether the AMD runtime is happy as well now.
Those (one per ID type!) were uselessly duplicated, and badly inconsistent
(some types were actually unlinking before deletion, others were only working if already unlinked!).
Now we use same func and same API for all types, by default deletion is performed only if ID is no more used,
set `do_unlink` parameter to True to always delete ID even if still in use.
Only exception now is with Scene, since we always want to keep at least one!
Note that this will change default behavior of some types (since unlinking is never done anymore by default).
Exiting Blender during argument parsing would leak memory
(tests, documentation generation, utilities).
While harmless, it hides real leaks which should be resolved.
This commit adds a new distribution to the Glossy, Anisotropic and Glass BSDFs that implements the
multiple-scattering microfacet model described in the paper "Multiple-Scattering Microfacet BSDFs with the Smith Model".
Essentially, the improvement is that unlike classical GGX, which only models single scattering and assumes
the contribution of multiple bounces to be zero, this new model performs a random walk on the microsurface until
the ray leaves it again, which ensures perfect energy conservation.
In practise, this means that the "darkening problem" - GGX materials becoming darker with increasing
roughness - is solved in a physically correct and efficient way.
The downside of this model is that it has no (known) analytic expression for evalation. However, it can be
evaluated stochastically, and although the correct PDF isn't known either, the properties of MIS and the
balance heuristic guarantee an unbiased result at the cost of slightly higher noise.

The RNA properties are still there (in case you really need them), except now
they will not be shown in the UI anymore, as this constraint really didn't
work well/at all when any of those was disabled. Most people shouldn't really
need to worry about this change.
If anyone wants a matrix-math challenge, they're welcome to try getting those
working for real, so that we can show these toggles again.
To get this working the least effort, I've had to expose the helper functions
used by the lasso and circle select keyframe-test callbacks (which are generic)
and expose them for use by the GP keyframe editing code too. Hopefully in time
we clean this all up and just write the code once to operate on "keyframes"
This only works in the Action and Dopesheet modes (which operate on FCurve keyframes).
Support for Grease Pencil and Mask Keyframes though is still pending.
As suggested by mendiobox:
* Don't show "enable editing" in the 3D view. You can already do this by switching
into stroke editing mode here, so no need for the duplication. (In other editors
though, this can't be done yet, so we don't do it)
* Make the "Convert" button into a dropdown so that you don't need to deal with a
a separate popup menu
* In the 3D view, don't show the selection + transform operators that can be easily
found in the menus too (as well as having commonly used shortcuts)
This new operator will delete any GP frame it finds on the current frame, regardless
of whether it's on the active layer or not. It will only remove the frames if the
layer is editable, but otherwise, it will just go for it.
The existing operator is great for use in the panel (where it only applies to the active
frame), but it was not so good for all the other places where tools can be invoked
(e.g. D-X, or Delete) as you're typically thinking about the whole scene more holisticaly
than just caring about a particular layer.
In rare cases intersect would attempt to add edges with the same vertex twice
from edge-vert / edge-edge intersections.
Solve by checking for duplicates when creating vertex-array for these types of intersections
(always under 3x comparisons, so not much overhead).
The function that assigns names to socket types missed an entry, therefore all entries after it were mapped to the wrong name.
Long-term, it might be a better solution to use a map to avoid issues like these, but for now this fix works.
Replaces `G.is_rendering` with `use_render_params` argument.
This is needed for Cycles, which attempts to restore render-preview settings from particles,
after it gets its own particle data, but fails to restore because
`G.is_rendering` was being checked in psys_cache_paths (and other places).
This commit adds operators and Outliner menu entries to reload or relocate a library,
and to delete or replace a datablock.
RNA ID API is also extended to allow ID deletion and remapping from python.

Reviewed by campbellbarton, thanks a bunch.
This commit changes a lot of how IDs are handled internally, especially the unlinking/freeing
processes. So far, this was very fuzy, to summarize cleanly deleting or replacing a datablock
was pretty much impossible, except for a few special cases.
Also, unlinking was handled by each datatype, in a rather messy and prone-to-errors way (quite
a few ID usages were missed or wrongly handled that way).
One of the main goal of id-remap branch was to cleanup this, and fatorize ID links handling
by using library_query utils to allow generic handling of those, which is now the case
(now, generic ID links handling is only "knwon" from readfile.c and library_query.c).
This commit also adds backends to allow live replacement and deletion of datablocks in Blender
(so-called 'remapping' process, where we replace all usages of a given ID pointer by a new one,
or NULL one in case of unlinking).
This will allow nice new features, like ability to easily reload or relocate libraries, real immediate
deletion of datablocks in blender, replacement of one datablock by another, etc.
Some of those are for next commits.
A word of warning: this commit is highly risky, because it affects potentially a lot in Blender core.
Though it was tested rather deeply, being totally impossible to check all possible ID usage cases,
it's likely there are some remaining issues and bugs in new code... Please report them! ;)

In the OSL node compilation code for the Environment Texture, is_linear was used as a socket.
However, there was no socket for it, which caused Blender to crash.
Adding a socket doesn't really make sense since it's an internal value and not a parameter
of the node, so it now just uses the variable directly.
Getting a new edit-derived-bmesh was always creating a deform-vert array, even when it wasn't needed.
Since this was called on redraw, in many cases it was doing it unnecessarily.
Now pass in a custom-data mask and only fill in deform-verts when needed.
Gives noticeable drawing speedup (~10-30% here).
The problem here was that there are five path types internally (diffuse, glossy, transmission, subsurface and volume scatter), but subsurface isn't exposed to the user.
This caused some weird behaviour - if all four types are disabled on the lamp, Cycles doesn't even try sampling it, but if any type was active, the lamp would illuminate
the cube since none of the options set subsurface to zero.
In the future, it might be reasonable to add subsurface visibility as an option - but for now the weird and inconsistent behaviour can be fixed simply by setting both
diffuse and subsurface to zero if the user disables diffuse visibility.
A new option for Font/Text objects vertical alignment:
* Top Base-Line (current mode)
* Top
* Center
* Bottom
The Top is the equivalent as the Top-Baseline with an empty line at the begin of the
text. It's nice to have this option too though, since if we are driving
the alignment via Python we don't want to add extra lines to the text
only to accomodate to the desired vertical alignment.
The Center and Bottom are as intuitive as their name suggest.
When working with text boxes, the vertical alignment only work for
paragraphs that are not vertically full.

BM_face_split_edgenet wasn't correctly detecting boundary vertices to walk over,
since vertices may be attached to boundary edges not part of the newly created face.
rB046adde64f16 was actually pretty useless (and broken), since issue ends up not being
in binary search code, but in generation of the 'summed weights' array used to distribute
particles over mesh items - looks like very small weights could lead to null accumulated
weights, wich was breaking binary search.
Fixed simply by adding a minimal, non-zero weight for mesh items to be allowed to emit particles.
Hopefully we are done with this distribution mess!
It is not possible to use a set split by name as valid input to
check_node_input_traversed - it needs a complete set of all nodes visited so
far. On the other hand, the merge comparison loop should only check nodes that
were not just visited, but found unique. This means that there should really be
two separate data structures.
Without the fix, check_node_input_traversed actually never returns true, so
only nodes without any inputs are processed.
For non-branched path tracing with a GTX 960 and CUDA 7.5, this gives a small reduction
in stack usage but mainly: 8% faster render on BMW, 5% on pabellon, 13% on classroom.
This is an initial commit for half texture support in Cycles.
It adds the basic infrastructure inside of the ImageManager and support for these textures on CPU.
Supported:
* Half Float OpenEXR images (can be used for e.g HDRs or Normalmaps) now use 1/2 the memory, when loaded via disk (OIIO).
ToDo:
Various things like support for inbuilt half textures, GPU... will come later, step by step.

At the moment light shading in Blender is produced in viewspace. Apparently, that's why
shader nodes work with normals in camera space. But it is not convenient for artists.
The more convenient approach is implemented in Cycles where normals are represented in world space.
Blend4Web Team designed the engine keeping in mind shader parameters readability,
so normals are interpreted in world space as well. And now our users have to use some tweaks, like
empty node group with the name "Replace", which is replacing one input by another on the engine side
(replacing working configuration in Blender Viewport by the configuration that has the same behavior in the engine).
This patch adds the ability to switch to world space for normals and lamp vector in BI and Viewport.
This patch is very important to us and we crave to see this patch in Blender 2.7 because
it will significantly simplify Blend4Web material creation workflow.

Note that this only removes the actual dependencies of Cycles on the
particle code in Blender, but not the internal "particle" definition
or the curve type handling inside Cycles. These structures may be in need
of some improvement themselves, but that is out of scope here.
There are a lot of cases here where deciding for removal is a bit tricky.
Many features have options for "use_particles" and similar settings. Only
features which actually store a particle object reference or work on actual
particle data have been removed.
