In some cases (e.g. using old userpref settings/keymaps)
it was possible to trigger a crash when the wrong GP/Annotation
operators were triggered in the wrong contexts (e.g. using
the old GPENCIL_OT_paint in annotation-only contexts like
all the 2D editors).
This commit resolves several issues that were caused by sloppy
code-churn + features that had been hacked on.
Since most animators find Motion Paths more useful than Armature Ghosting:
* Move Motion Paths before Ghosting settings (less scrolling)
* Collapse Ghosting panel by default
* Open Motion Paths panel by default instead
Pretty minor, from 0.6 to 0.8, but the improvement is noticeable
especially when using a stylus, without overlapping too much with
the buttons and dropdowns in headers.
Rendering OpenGL/Preview is accessible from each editor.
Render settings are accessible from the Film menu when in OpenGL/Preview engine.
It wasn't always predictable especially with Workspaces without or with many viewports.
Also reordering of items, renaming and removal of superfluous icons.
texelFetch return vec4(0.0) if the target pixel is outside the texture
rect. So we mimic the default repeate mode that we have for linear
interpolation.
Fix T56156 Mapping-Node doesn't work
The idea is simple: do not provide full topology to OpenSubdiv, leave
edges creation to OpenSubdiv itself. This solves issues with non-manifold
meshes which were known to fail, including the ones from T52059.
On a positive side we can simplify our side of converter, keeping code
shorter.
it is still possible that we'll need to ensure all loops has same
winding, but that is less things to worry about.
Applies to vertices and edges. Biggest annoyance here is that OpenSubdiv's
topology converter expects that there is no loose geometry, otherwise it
is getting confused.
For now solution is to create some sort of mapping from real Mesh vertex
and edge index to a non-loose-index. Now the annoying part is that this
is an extra step to calculate before we can compare topology, meaning FPS
will not be as great as if we knew for sure that topology didn't change.
Loose edges subdivision is different from what it used to be with old
subdivision code, but probably nice feature now is that endpoints of loose
edges are stay at the coarse vertex locations. This allows to have things
like plane with hair strands, without need to duplicate edge vertices at
endpoints.
All this required some re-work of topology refiner creation, which is now
only passing edges and vertices which are adjacent to face. This is how
topology refiner is supposed to be used, and this is how its validator
also works. Vertices which are adjacent to loose edges are marked as
infinite sharp. This seems to be good-enough approximation for now. In the
future we might tweaks things a bit and push such vertices in average
direction of loose edges, to match old subdivision code closer.
Having 'flag, flag2, flag3' is getting out of hand especially
when we support increasing the size of types.
Make flag2 into an int.
Note, this looses the 'show world' option,
but it's not such an important setting.
This also include a small optimisation (remove of a double loop and half of
the memory allocation for hit points)
This should fix T55946 Crash using knife tool on mesh with large number of

Tried with a 500K vert suzanne and it seems fine.
instead of being ThreadLocal and leading to incorrect usage.
We still enforce no framebuffer when changing context. We can lift this
restriction later.
After clearing motion paths from objects, those objects needed to be
tagged for copy on write so that the copied data (i.e. viewport)
recieve the changes (i.e. removed paths)

Usage of matcap image uniform had different ifdef than definition
of that uniform. Assuming the usage was correct, and the definition
needed an update.
Prevents shader from compilation failure and from aborts in debug
builds.
The idea is to create vertices along the coarse edges once, without
splitting coarse edges on separate ptex faces. This requires some
indexing magic, vertices within a patch are no longer sequential.
Not sure how to make it nicer without such a black magic looking
calculations (which are basically boiling down to mimicking order
of verts/edges creation).
In the current offsets calculation loose verts and edges are not
properly taken into account, but those are causing topology refiner
to fail anyway, so it needs a bit deeper change.

This ignores the scene color managment view settings for solid mode and
lookdev when not using scene lights and world. The scene settings are
intended for tweaking renders and should not affect studio lighting and
matcaps.
There may be cases where a simple sRGB transform is better than Filmic
and we could add configuration for this. Not sure if it really matters
and it may be better if we just assume matcaps and studiolights are all
created for one view transform.

By popular demand, the CLean Keyframes operator will now
leave handles and other interpolation settings untouched.
Previously, it would recreate the keyframes from scratch,
keeping only the frame + value, under the assumption that
the handle information was "bad" (i.e. the source of bumps
and roughness, due to bad hand tweaking). However, since
most animators use this on hand-keyed animation instead of
motion-capture data, this assumption didn't hold, and was
actually overly destructive - wiping out lots of hand-adjusted
curve data.
This is in preparation of upgrading our library dependencies, some of which
need C++11. We already use C++11 in blender2.8 and for Windows and macOS, so
this just affects Linux.
On many distributions this will not require any changes, on some
install_deps.sh will need to be run again to rebuild libraries.

This will ensure origindex is set correct for cases when there is an
array modifier prior to subsurf.
Gathers information about object geometry and textures. Very basic at

Things which needs to be included still:

- Device array sizes. Again, not under artists control, but is added to

- Memory peak at different synchronization stages.

In other parts of blender's codebase World is sometimes called Scene.

While changing the shading normal is a great way to add additional detail to a model, there are some problems with it.
One of them is that at grazing angles and/or strong changes to the normal, the reflected ray can end up pointing into the actual geometry, which results in a black spot.
This patch helps avoid this by automatically reducing the strength of the bump/normal map if the reflected direction would end up too shallow or inside the geometry.

Previously it was ptex faces which were subdividing to the same
resolution. This was looking like more details for non-quad faces,
but was also causing discontinuity in the edge where quad touches

Now ptex faces which are coming from non-quad faces are subdivided
at a half of resolution, matching old behavior and solving
discontinuity problem.

This is a part of the D3504.
The issue was caused by Render Single Layer option enabled, which is
very handy for artists work, so they can hit F12 and see view layer
they are currently working in a final rendered state. This saves a lot
of time since all the "non-interesting" objects are ignored for such
iterations.
However, for the render farm we need to render view layers which are
explicitly set for render, and ignore active view layer.
Reasonable solution seems to be to ignore the Render Single Layer
option when rendering from the command line. It is really something
more like UI behavior option.
Hopefully this will fix issue with camera rig where camera properties

Previously it was calling `BKE_pose_rebuild()`, such thing shall never
be called from drawing code! Hopefully this now works as expected and
that horrible hack is not needed anymore.
`BKE_pose_rebuild()` should (ideally) always trigger a rebuild of the
depsgraph, since it can add or remove posechannels.
This function now takes a Main parameter to ensure that related
depsgraphes are tagged as dirty (kept it optional, for some corner cases).
We should also probably double-check calls to that function, think in
theory it should only be called from depsgraph itself? But for now...
Damped Track by specification attempts to arrive at the desired
direction via the shortest rotation. However with opposite vectors
there are infinitely many valid 180 degree rotations. Currently
it gives up and does nothing.
I think that it would be more reasonable to resolve the ambiguity
arbitrarily, so that Damped Track won't have a weird dead zone.
To make it more predictable I use a local axis.
In addition, the singularity area vicinity has some floating
point precision problems that result in significant jitter.
This applies workarounds for two causes of instability.

GPUFrameBuffers were being free when no context was attached or in the
wrong gl context. This make sure this does not happen again.
You can now safely free any gl resource from any thread (well as long as
it's not used anymore!).
This increases stack memory usage some, and ideally we'd support a dynamic
size. But this is quite difficult on the GPU and hopefully 32 is enough even
for very complex cases.
When editing a Material the depsgraph can throw away the evaluated ID
before the preview job localized the said ID.
To fix this we localize the ID from the main thread.
Also fix WM_OT_previews_ensure crashing because of no depsgraph.
Was only visible when doing command line, since it was happening due to
cache-free policy which was aimed to bring memory usage down.
The issue is that if object with particle system is used as a nested
duplicator multiple times, it will only generate children first time,
and after that its caches are freed. After that duplication system
can not generate any instances, since the path cache is lost.
Now we delay caches free to after all objects are synchronized, which
ensures all instances are generated.
This will increase a memory peak a bit during object synchronization
time, but overall it shouldn't be that bad, since memory footprint
after synchronization will stay the same as before this change.
The ultimate thing to do here would be to drop the whole dependency
graph away, but this will require:
- API on engine side, to inform it to drop the dependency graph.
- Changes in Cycles report system to NOT use evaluated scene to get
scene name (evaluated scene will be gone with dependency graph).
The idea is to use this as a replacement of old CCG, now it is
based on OpenSubdiv. The goal is to reduce any possible overhead
which was happening with OpenSubdiv used by CCG.
Currently implemented/supported:
- Creation from mesh, including topology on OpenSubdiv side,
its refinement.
- Evaluation of limit point, first order derivatives, normal,
and face-varying data for individual coarse position.
- Evaluation of whole patches.
Currently not optimized, uses evaluation of individual coarse
positions.
- Creation of Mesh from subdiv, with all geometry being real:
all mvert, medge, mloop, and mpoly.
This includes custom data interpolation, but all faces currently
are getting separated (they are converted to ptex patches, which
we need to weld back together).
Still need to support lighter weights grids and such, but this
is already a required part to have subsurf working in the middle
of modifier stack.
Annoying part is ifdef all over the place, to keep it compilable
when OpenSubdiv is disabled. More cleaner approach would be to
have stub API for OpenSubdiv, so everything gets ifdef-ed in a
much fewer places.

Currently we don't care that much, since all the work is done in

Main goal is to make API simpler to follow (at least ion terms what
is defined/declared where, as opposite of handful big headers which
includes all the declarations), and also avoid a big set of long and
obscure functions.
Now C-API files are split into smaller ones, following OpenSubdiv
behavior more closely, and also function pointers in structures
used a lot more, which shortens functions names,
UV integration part in GL Mesh is mainly stripped away, it needs
to be done differently. On a related topic, UV coordinates API in
converter needs to be removed as well, we do not need coordinates,
only island connectivity information there.
Additional changes:
- Varying interpolation in evaluator API are temporarily disabled,
need to extend API somewhere (probably, evaluator's API) to inform
layout information of vertex data (whether it contains varying
data, width, stride and such).
- Evaluator now can interpolate face-varying data.
Only works for adaptive refiner, since some issues in OpenSubdiv
itself.
Planned changes:
- Remove uv coordinates from TopologyConverter.
- Support evaluation of patches (as opposite to individual coordinates
as it happens currently).
- Support more flexible layout of varying and face-varying data.
It is stupid to assume varying is 3 floats and face-varying 2 floats.
- Support of second order derivatives.
- Everything else what i'm missing in this list.

Numeric input allowed mix of editing and hotkeys which were interpreted

This meant entering '1.0*3' needed to be typed as '1.0**3'

Pressing '/' gave the reciprocal of the current number
which could be useful.
Test removing this feature, so only full numeric input is supported.
The approach of setting 'refresh' flags on the modifier, and performing
the associated actions when the modifier is being evaluated, is a bad
one. Instead, we use the separation of the original and the evaluated
copy to 'refresh' certain things (because they simply aren't set at all

Old behavior: tagging ID with DEG_TAG_COPY_ON_WRITE will do copy-on-write
(as requested), but will also flush changes to all operations with depends
on it. This means, for example, tagging object for copy-on-write will force
its modifier stack to be evaluated.
This was needed in the earlier days of copy-on-write when things were not
well defined and when lots of areas were not doing proper tagging.
New behavior: tagging ID with DEG_TAG_COPY_ON_WRITE will only ensure copy
of the dadatblock is up to date, without flushing updates to any dependencies.
This means following things:
- We can update parts of ID without invoking heavy computation of other
parts of same ID. For example, tagging object for COPY_ON_WRITE update
on mode change will not force modifiers stack to update.
- If some dependent datablock is dependent on pointers which are invalidated
by copy-on-write (like, evaluated mesh referencing custom data layers from
original mesh), this will either require explicit tag or explicit relation
in the dependency graph.
Currently can not find a faulty case since tagging of mesh happens with
either 0 (which means, everything) or with GEOMETRY, which also forces
all dependent modifier stacks to be re-evaluated.
This fixes missing PBVH when going into sculpt mode (sculpt mode toggle
was tagging object for COPY_ON_WRITE update, which was forcing modifier
stack to be updated, which was freeing PBVH.
Some other operations might also become faster with this change.
Instead of running code to create a keymap, store them as data.
This allows for keymaps to share content as well as running
transformations at load time.
Now we light with just a user defined HDRI by default, which is useful
for material setup and texture painting and lighting without having to
set up any scene lights.
Previously it would use the scene world without lights by default, which
in some files is just black.
Shortcut strings would be offset to the left to make space for the triangles,
breaking the alignment with other shortcut strings. Now this alignment is kept
by making menus slightly wider if there's a sub-menu triangle visible, making
room for the triangle.
Trying to have a single option for this is too likely to be
insufficient in some cases.
Instead, support object type visibility & selectability per view-port.
Remove depth testing flags from motion path pass drawing,
so that they always appear to draw in "x-ray" style on top
of everything, making it easier for animators to see what
they're doing.
This fixes an issue introduced in d192d72312.
When starting up, the UI hasn't been fully initialised yet, and calling
wm_event_do_depsgraph() can trigger icon updates when the startup file
contains an image, causing a segfault due to a not-yet-initialised ghash
for the icons.
The flag was only used in readfile.c, and resulted in a delayed call to
BKE_ocean_add(); this call is now immediately made instead as it's not
very expensive.
The previous commit only solves the problem when using the default
theme using factory settings. For previously saved themes, there could
still be problems, as the alpha values were still 0.
This commit improves the logic here so that while keyframe points on
unselected F-Curves will still get faded out (to not stick out too much
from the curves they live on), but the effect will not be as pronounced
(i.e. the points will stay visible all the time).
Restore theem setting default for Graph Editor's vertex,
with default alpha set to 1.0. The alpha value here needs
to be non-zero, as the alpha values currently get used
when drawing verts.
This makes it possible to have a single shading nodetree that contains
separate Cycles and Eevee shaders. By default the target is set to All
so shaders are shared.
* Z now goes to solid mode when in lookdev or rendered mode.
* Alt-Z was broken after removal of texture mode, now toggles lookdev mode.
* Simplify code by turning it into a single operator.
This patch will allow users to customize what object types will be drawn by the object mode overlay.
It supports: Empties, Lamps, Cameras, Speakers, Armatures and Lightprobes.
It currently does not support Physics objects due to the overlap it has with other objects types.
Also be aware that in pose mode the armature is drawn, but not by the object mode overlay

Will help entering sculpt mode on file load by making it possible
to fully initialize sculpt session. The goal is to make sure PBVH
exists since the very beginning of file open (missing PBVH is a
reason why object is not visible before first stroke).
This is not enough yet to fully solve the issue, since entering
sculpt mode tags object for Copy-on-Write update, which frees
PBVH.
Added a option to the overlay popover that controls the visibility of
non-renderable objects like lamps, cameras, speakers, armatures, curves
empties and force fields.
After discussion we went for a single option with more detailed check in
the object_mode draw engine.

Textures in 16 bit integer format are sometimes used for displacement, bump and normal maps and can be exported by tools like Substance Painter. Without this patch, Cycles would promote those textures to single precision floating point, causing them to take up twice as much memory as needed.

When switching the workspace in a window that does not yet have a layout
for the newly active workspace, we now duplicate the layout from the
previously active workspace. Previously it duplicated the layout from
the first window in the newly active workspace.
It was a bit odd that the scene was stored per window but not the view
layer. The reasoning was that you would use different view layers for
different tasks. This is still possible, but it's more predictable to
switch them both explicitly, and with child window support manually
syncing the view layers between multiple windows is no longer needed
as often.
* Main windows show a topbar and statusbar, and select a workspace and
scene. They are created with Window > New Main Window.
* Child windows do not show a topbar or statusbar. These follow the
workspace and scene of their parent main window. Created with Window >
New Window or View > Duplicate Area into New Window.
* The purpose of this change is to support multi monitor setups where you
just want to put more editors on the other monitors. Without multiple
topbars and statusbars, working within a single workspace and scene.
Creating multiple main windows is intended to be a concious choice to
do different tasks in different workspaces and scenes.
* Note these changes do not currently affect how the operating system
treats the windows.
* When changing the workspace, the layout in all child windows changes.
This makes sense if we consider child windows to be just a way to
extend the main window across more monitors. In some case it may be
useful to keep the same layout though, we can add an option for this
depending on user feedback.
Node link menus (like shader settings in Material properties) used a slightly
brighter variant of the menu widget. Making it hard to style and match the rest.
Make it use widget_menuiconbut, which is just the menu widget with an icon and no arrows.
Thanks Brecht for the help!
Shading is supposed to be dealing with draw manager batch cached
thingamajigs, but was causing full object update.
This was causing both flickering in sculpt mode (PBVH was removed,
why it was SOMETIMES restored before draw is a mystery), and was
also causing things to be really slow.
Workaround for now until all editors tabs share the dedicated Tab theme
settings under User Interface (which the top bar is currently using).
Thanks SimonStorl-Schulke from devtalk forum for feedback.
This deduplicates the calls for tile (un)mapping and allows to have a target buffer that is different from the source buffer (needed for baking and animation denoising).
Based on discussion with @eyecandy & @venomgfx,
we agreed that Tab drag/click, is too easy to accidentally press
while moving the cursor.
It's also not typical to activate the operator on release which
introduces a small lag switching edit-mode.
This is a shame since in some ways its a nice way to re-use the key,
overall it just feels a little too unpredictable for such an important
action.
This commit makes the following changes.
- Tab: toggles edit-mode.
- Ctrl-Tab: opens pie menu.
- Ctrl-AccentGrave: toggles manipulator.
Note, while AccentGrave isn't always available
this shortcut is not essential.
This is the same approach as 98a0bcd425
applied to soft body simulation. In short, CoW copies share the point cache,
and treat it as read-only except when the depsgraph is active.
This prevents having to wrap each call to sbFree() in an if(ob->soft)
condition and assign ob->soft = NULL after calling.
Furthermore, passing `Object *` allows us to change freeing behaviour
depending on whether the object is an evaluated copy or an original (not
done in this commit yet).
This unifies two almost-identical functions at the expense of having to
add one single 'flag' value at one call.
This makes copy_softbody() aware of the source/dest objects, allowing it
to make a distinction between doing depsgraph evaluation copies and real
object copies. This will be used in an upcoming commit to ensure that
the pointcache is shared between CoW copies, similar to the current
approach for rigidbody simulation.
This is because depth test is set before drawing anything now. There is no
case where we want to draw without depth test that is not selection and
this case is not handle by v3d->zbuf anymore.
UI assume depth test is off by default. The DRWManager assume it's on.
This should fix T55623.
In some cases we want associate use an operator for a tool
for introspection, so we can for eg, automatically
use the same binding for in the popup toolbar.
Space-G/R/S for transform now work as accelerator keys again.
Also Space-E for extrude.
Selected color is now .9 alpha so keyed/animated/driven statuses
show through when widget is active. Assign color for overriden state.
Also fix progress bar not visible.
Make room for Alt-A to be used for de-select.
Discussed with artists in studio & @venomgfx,
- Use Ctrl-Space for animation.
- Use Ctrl-Tab to toggle manipulator.
- Remove mirror transform binding.
it is possible that two threads will request same undo node, only one
of them will initialize the node. The issue is that initialization is
happening outside of a lock, which was making one thread to use non-
initialized node.
If this change is ever a bottleneck, make a lock inside of node.
When playing animations the anti-aliasing was not reset, resulting in
ghosts from previous frames to be drawn. Also when playing animations
and switching to X-Ray mode for the first time would most likely
result in a write to uninitialized memory.
The shortcut labels now use the "Item" theme color. Its contrast for hovered
items is a bit low, but not too bad.
Note that this also changes the color of the little toolbar triangle to be grey
(the same color we use for the keymap label). IMHO that looks better though.
This doesn't update any themes other than the default one.
Part of T54711.
Operators ignored edges along the screen-layout bounds. They should've ignored
those along window bounds instead.
Although the global areas can not be joined/split, the adjacent areas can. So
the menu should still be shown.
Had to change the return value of area joining operator, so that an error report
can show up when trying to join over a global area edge. Think this is fine to
do, but you never know with such stuff.
Preferably we'd gray out the "Join Area" item in the menu when clicking on the
edge of a global area. Unfotunately the operator uses coordinates passed as
operator properties to find the right edge/areas, which we cannot access from
the poll callback.

Original description:
I've encounterd into a problem with blender 2.8.
See the example screenshot (scene, shader setup). For some materials it's not enough to calculate hash based on fragment code and defines. In some cases attribute names may change. And if we change uv set name, for example, vertex shader is not recompiled, and another attribute name inside it is used.
This allows key bindings: link/append and user-preferences
to be accessed via keys - without having to assign keys to each action.
- F1: Context sensitive help.
- F2: File Context Menu.
- F3: Search.
- F4: Window Context Menu.
Other keys F5..10, remain free,
ideally they can be kept for user actions.
This reverts commit 9129319647.
This meant users needed to select everything to see relationship lines,
this isn't always easy since objects can have limit-selection set.
This could be made into an enum option if it's important.
Just like the top-bar, the status-bar can now be hidden/collapsed by dragging
its edge. We display a small line with the editor outline color then, so there
is something that can be dragged up to un-collapse the area again.
This collapsed state is not written to files yet.
For example collapsing the lower part of the topbar with 2x interface scale
would hide the top-bar header region. There were also more asserts when changing
window size and moving area edges afterwards (same assert as in T55298).
Fixes are similar to e626998a26.
With all the recent fixes I've done, area geometry handling should be stable
again. Let's hope I'm right :)
This used to be rather cryptic and it was easy to forget the `+ 1` which in fact
is needed to get the correct width/height, see e626998a26. This should
also fix some minor off-by-one errors.
This reverts commit 357b72e0a7 which caused
the issue, we need a better fix for that cosmetic issue from T50862. For
now displaying keyframes and drivers is the more important one.
Added a compile directive in order to test SH4 in stead of SH2Win.
For now I disabled SH4, it is a bit more clear, but has a small
performance impact. Will check later for a better approach
There is now a manual refresh button on the panel to update the list
of objects in case it changes, and it also gets refreshed when changing
the collection or toggling the use count option.
This is a bit more manual but the previous code of refreshing the
list while evaluating the depsgraph was unreliable.
This also fixes it to take properly take into account visibility, and
to work with linked collections for which index writing was missing.
Access to main database is actually rarely needed, but some custom
'apply' functions do need it (like Collections' overriding of objects or
children collections).
First frame of the TAA is just a regular copy of the previous buffer. so
we write directly to the final buffer and skip the taa shader. We do
init the history buffer via blit so it will be initialized for the other
iterations.
When AA was enabled a new buffer was created. As the composite pass is
already done, we can reuse earlier buffers.
For the deferred rendering we reuse the color_buffer_tx and for the
forward rendering we reuse the transparect_accum_tx.
Most of the times the materials differ due to the object_id. This was an
overhead and resulted in instabilities on Intel graphical cards. This
commit will revert the Material Data UBO and replace it with normal
uniform.
Caused by ca8f787349. This issue is in master actually. Fixing it there
would cause conflicts so won't do that unless needed ;)
Steps to recreate were:
* Split properties editor into two (default startup.blend)
* Move both properties editors to the bottom, so only their headers are visible
* Move the upper edge of the upper properties editor up and down
Although it doesn't happen everytime, you may see the edge between the timeline
and the 3D view move, while the region drawing doesn't update.
What happened is area edge snapping allowed to snap the edge outside of window
bounds (we snap to a 4px grid by default), which screen_vertices_scale
interpreted as window scaling and thus run area size updates.
Referring to ca8f787349. Thought in this case the simple `+ 1` would be
correct, but we need to make the same pixel adjustment as we do in other places.
Simply moving the properties editor of the default startup.blend all the way to
the bottom could trigger this. Calculating limits for area edge moving would use
screen bounds instead of entire window bounds (screen + global bars).
Added assert that should help debugging further issues like this.
This puts the wireframe on top of the weight in weight paint mode,
sculpt mode ...
Wireframe should be colored differently if the object is in paint mode
but it's not there yet.
Unbuffered stdout makes stdout and stderr better synchronised, and helps
when stepping through code in a debugger (prints are immediately
visible). We don't output much to stdout anyway, so this isn't likely to
cause any performance issues.
- TAA is also enabled for Forward rendering
- Uses less GPU memory (removed one history buffer)
- TAA is done after the color management
- consolidated the aa code between forward and deferred rendering
(workbench_effects_aa.c)
I.e. we can now use REPLACE operation directly on items of an RNA
collection, when those items are ID pointers.
Again, mandatory to support new Collection's objects/children override.
To prevent the pointcache from being copied-on-write too (and requiring
copying back), the cache is now shared between the original and
evaluated scenes. Reading from the cache is always allowed; running the
sim and writing to the cache is only allowed when the depsgraph is
active.
Some pointers have moved from RigidBodyWorld (RBO) to
RigidBodyWorldShared (RBOS). writefile.c copies some pointers back from
RBOS to RBO so that the file can still be opened on older Blenders
without crashing on a segfault.
The RigidBodyWorldShared struct is written to the blend file, because it
refers to the PointCache ID block.
The RigidObjectShared struct is runtime-only, and thus not saved to the
blend file.
An RNA getter-function is used to hide the new 'shared' pointer. As a
result the Python API hasn't changed.

Key shortcuts and explanation about how to use the tool should go to the
status bar, but other info can in the header so it's near where the user
is working. This distinction has not been made yet for all operators.
When RNA path was for a collection item, we'd falsly get NULL final
property (and wrong final RNA pointer too).
Own stupid mistake in some previous commit, iirc.
The preview files had all the other collections excluded from the view layer.
Although this fix the problem, it probably means we ignored some existing
2.8 files in recent changes. Which is likely fine anyways given that 2.8 is
experimental.
Assert from BLI_assert by default in debug builds
(instead of just printing a warning).
Some developers ignored this, causing errors for others.
Better debug builds cause hard error so code isn't ignored.
Disabling is still useful when bisecting or testing outdated code.
When meshes has no uv layer, but has a texture assigned there was a uv
layer allocated which was corrupt. When no uv layer is available now
there won't be a vbo created. This might impact performance as the draw
cache does not cache this result.
Current implementation works with at most of 3 layers, but was not
checked during hair drawing leading to reading from uninitialized
memory.
This commit limits it to the number of layers that is used during
compilation of blender.
Based on animator feedback, accidentally not clicking on the manipulator
handle had unpredictable behavior.
This functionality will be moved into the manipulator and made optional
(add an invisible fallback manipulator).
textures were not always drawn as the material did not always include
the image in the hash. Not sure if this will solve all cases, but it
definitely works better with this change.
This translates the gl calls to the new GPU_ wrappers from D3501.
Given it's tedious and repetitive work, this patch does as much as it can with search + replace, the remainder of the gl calls will need to be manually dealt with on a case by case basis.

Now the name/collection filters run when there's some text,
and don't run when the box is empty, thus reducing an extra
step that was needed before these options could be used.
This commit is an experiment in using popovers as a place to house some
of the filtering options for animation editors, in line with what's taking
place in the Outliner with the filtering popover there too.
Right now, the most frequently used/changed options are still available
on the headers (i.e. the "Only Selected"/"Hidden"/search fields), while
everything else (i.e. the per-datablock filters, which were already hidden
behind a collapsed-toggle button before) now live in the popover.
We have to discard the batch in smooth case, because we are modifying
the index buffer (flat shading don't need it, only changes vertex buffer
on redraw, which is safe).
Many thanks to @fclem for his help on debuging/understanding what was
wrong here!
The latest clang compiler (at least the one in Xcode 9.4.1) warns about the register keyword and macro expansions using defined().
Since these warnings come from third party code, we can't address them directly in Blender. Silencing them via #pramgas will
at least keep the warnings during a build down to the ones that are relevant to Blender code.
At the moment it's using a hardcoded gray color that conflicts with
themes using gray for the header text. Instead use a slightly brighter
background color to make it stand, yet still use a theme setting.
Force Fields and Falloff are now simpler and more compact
by removing unnecesary labels (there was a text label just for one option)
Particle Force Fields Falloff is now a sub-panel of each effector type,
rather than just as a section with label.
Move Navigation Manipulator toggle next to Mini Axis as they are related
(and in the future merged into one pulldown) and rename Manipulator

of manipulators. Also move to the first column next to other viewport settings.
- Use per context menu lists to support menu editing.
- Support for different kinds of menu items since this may be needed

BLF' blf_font_width_to_strlen() could easily generate strings with up to
nearly two pixels length over requested limit!
Note that the fiddling between floats and ints values make things really
confusing here... :/
There is still a few limit cases where, even though computed str length
is now always below reauested limit, we still get first letter
disappearing, no idea why currently.
This method is a bit more optimized than the very first one
because it does not rely on the adjacent faces properties.
That said it's still a bit slower than the per vertex method.
createOffscreenContext left the new context bound to the calling thread

Instead of lazy initializing, add UI_popup_menu_end_or_cancel

To find all effectors in the scene, we need to loop over all objects.
Doing this during depsgraph evaluation caused crashes because not all
objects are guaranteed to be evaluated yet.
To fix this, we now cache the relations as part of the dependency graph
build. As a bonus this also makes evaluation faster for big scenes,
since looping over all objects for each particle system is slow.
Fixes T55156.
In stead of a single refresh function that re-init the whole system. The

Silences the following strict flags from external libraries:
- -Wclass-memaccess
- -Wswitch
- -Wtype-limits
- -Wint-in-bool-context
Needed to tweak macro a bit, since the old logic was wrong:
we can not use CXX flags for C compiler, need way more strict
separation between what goes where.
We draw small numbers over the icon of multiple objects of the same type.
Also, we make all inlined elements to be non-clickabled.
For modifiers we still do it the old way. In this case it is more important
to see the order then the ammount.

Again, we cannot actually get rid of G_MAIN global access here, so in

Avoids usage of uninitialized memory when inversion fails.
That uninitialized memory can cause object to become visible when
it is supposed not to or other artifacts like that.
Longer term solution would be to check every instance of invert_m#

extra utility functions).
There was a Full Shading bool that was shared across the WP, VP and TP
modes. This commit makes some changes:
- Replace the bool with a factor. This gives the user more control on
the visibility.
- Also draw it on top of the Material and Rendered mode so the user can
control what he needs. In certain cases you don't want to see the final
rendered material, but the actual texture.
- Removed the skipping of objects when in paint modes. As now the paint

Transform evaluation does depend on that matrix, but relation was never
in dependency graph. It was not even in the old dependency graph, which
makes me wonder how this thing worked reliably to begin with.
Should fix flickering issue in the render farm.
Transform evaluation doesn't not depend on objects which are being duplicated,
so should not be any regressions here.
The whole relation should probably be gone as it's kind of rooting back to
legacy times, but that would need more clear research and investigation and
regression testing.
Removing that stuff should be valid with new depsgraph/modifiers stack
evaluation system... BUT it might not be, so rather have those in
separate own well-isolated commit.
This was actually rather hairy, this code is huge and complicated, easy
to make mistakes...
Good thing is, it will allow for significant simplification and more
(name) cleanup in following commits ;)
I was originally going to just expose the filtering options fo the timeline
too (via popover), to provide full access to the filtering options here too.
However, investigating further, that would've caused problems when trying to
use the Next/Prev Keyframe operators in other editors (see comment in code).
For now, the simpler solution is to just sync the scene-level flag (used for
this option) back to the dopesheet settings (used for generating the summary
channel used for displaying keyframes), to buy some time to investigate more
carefully.
When in forward rendering and Object outline was disabled every render

the use of the texture drawtype is limited. so who should we have it

The calculation of the irradiance buffer was slow. Now it is only
calculated when it is being used (background_alpha > 0.0)
this solves the freeze when switching to LookDev mode.
Also changed the default calculation to use the Spherical Harmonics
calculation. This is able to generate the irradiance buffer fast, but is
less accurate. As the irradiance buffer is only used for visual
guidance speed is more important than accuracy.
Added compile directive to switch between the implementations.
(see STUDIOLIGHT_IRRADIANCE_METHOD)
Disabled caching the irradiance buffer when
STUDIOLIGHT_IRRADIANCE_METHOD_SPHERICAL_HARMONICS is used as it is not

This is a step towards being able to just choose the "Drivers Editor"
from the editor selector, and have everything displayed, ready to use.
Currently there are a few problems to resolve still:
1) This update callback doesn't run when changing the mode via the
editors selector in the UI. (Note: This problem also affects the
Timeline vs Dopesheet, causing a lot of initialisation work to be
skipped)
2) There's some missing redraw/refresh here to cause the properties
region to actually show. You need to resize the window for that to
happen now.
This shouldn't really be part of the windowmanager code. Pulling it out
now, so that we can reuse in RNA when switching display modes,

many cases, resulting in mode changes to the Timeline and back (via other
editors) causing Dopesheet Editors to reset back to "Action Editor" mode.
1) Creating new Dopesheet Editors (e.g. change the default 3D view to
a Dopesheet editor) would default to displaying the "Action Editor",
since mode/mode_prev == 0 represents the "Action Editor" (for backwards
compatability reasons), while mode == 3 is for the "Dopesheet"
2) If you set the Dopesheet Editor to another mode (e.g. "Grease Pencil" mode),
change to another editor (e.g. Shaders), then come back, the mode would
get reset to "Action Editor".
Expose search like in 2.7, we could make it pop on Ctrl+F to save space if needed.

Based on mockups and feedback session with William
- Orientation of the cubemap were not conform cycles and eevee
- one side of the cubemap was flipped, so one side was overlit and the
other side was to dark.
In the outliner there are now icons for it, Ctrl+Click isolates a
single collections.
In the 3D view, Ctrl+H key opens a menu that is more or less the
equivalent of the old layer buttons in the header. Regular Click isolates
the collection, Shift+Click toggle the collection visibility. Pressing
number keys and letters works in this menu, which can help for quickly
selecting a specific collection.
Shortcuts for quick switching by just pressing 1/2/3/.. keys are available
again. The order can be confusing with nested collections, but that seems
unavoidable. The first numbers control the top level collections, and then
sub collections if numbers are left.
Remaining design issues:
* The 3D view menu needs to be improved: support for sub collections,
staying open on shift+click, access from the 3D view header somewhere,
shortcut key display.
* Currently collection hiding just controls per-object hiding, we plan
to separate this state still so alt+H doesn't affect collection hiding.
Note this is now separate from H key hiding, and meant for more persistent
ways to define which objects are relevant to the viewport or render.
This avoids some cases where you'd have to create collection specifically
to hide objects for viewport/render.
H hides selected objects, Shift+H hides unselected objects, and Alt+H
reveals hidden objects.
This hiding state is distinct from restrict viewport and render, and
meant for temporarily hiding objects without affecting more persistent
collection hiding.
Object hiding is per view-layer, same as selection. It affects the
viewport and any preview renders in there, but not final renders.
In the outliner, different icons are now used for temporary hiding, and
restrict viewport and render. Hidden objects are greyed out.
Remaining design issues:
* For lamps we probably still want to keep their effect on the scene,
currently they are fully disabled by hiding. Arguably mesh lights or
even objects being reflected or casting shadows are not that different
but perhaps the special lamp exception from local view should remain.
* We need a feature still to disabled this hiding for specific viewports,
for render or animation preview where you want to see the entire scene
while working in another view.
* We need a new icon for restrict viewport, for now it uses a grid similar
to the 2.4 icon.
* Hiding objects does not preserve selection state as it did in 2.7,
it's probably convenient to support this again?
Validate some cases using G_MAIN instead (I don't think we want to work
on any other Main than G.main one when registering/unregistering nodes
etc.).
And when freeing, all ID not in Main shall now be tagged accordingly, so
we *should* not need to do that stupi search over all ntrees in G.main

Happened when deleting many studiolights at the same time when the
previews were still beging calculated in the background.
Added a free function callback that is filled when the preview is being
generated. This free function will then kill the preview job
This patch also removes icons that are not valid anymore so the user
cannot accidentally render an icon where the studiolight is invalid.
In the end we should use a add/remove function in the studiolight as
currently icons are recalculated too much.
`mesh_get_eval_final` and friends could call `mesh_build_data`, which in
paint/sculpt mode would call `BKE_sculpt_update_mesh_elements` which

Would compare evaluated ob pointer to original one...
Found while investigating some errors in incomming cleanup, but this was
probably generating lost of other issues in some cases...
This is a temp fix for a better system.
Currently the studiolights can be referenced by a WM_job and being freed
via the API. This can happen when removing a studiolight via the
interface.
As the studiolight has no relation with the job, it is hard to detect if
it is still being used. I tried with a Mutex and a Thread Queue but they
were failing.
So the current temp fix is to keep the studiolights in memory until you
close blender. This Must be fixed ASAP! I added this fix so normal cases
can workish.
I moved some code from ED_rigidbody_object_remove() to
BKE_rigidbody_remove_object(), so that calling the latter doesn't leave
the object in rbw->group (causing a crash later on when rebuilding the
depsgraph).
The idea is to only use pointers to particles in original object when
creating an edit structure. The derived mesh we get from evaluated
object.
The rest of the commit is just keeping pointers in sync.
This makes it possible to perform re-evaluation of the scene without
having to re-run the simulation.
The CoW → Orig copy is only performed when the depsgraph is active, so
as to not influence the current scene while rendering in the background.
Alternatively, we could have the CoW copy share the cache with the
original to prevent too much copying of cache data. This will be faster,
but I'm not sure whether we can reliably check the DEG_is_active()
status at CoW copy creation time.
- the result of the SH2-coeffiecients are stored in a bin file (3*9

SculptSession.mode_type wasn't initialized until painting,

rBe0c088f8fb5a introduced offline rendering support on windows, sadly it was trying to use the desktop window for getting a context, which given SetPixelFormat can only be called once for any given HDC was an unfortunate choice.

Not sure why remap call for static override reference ID pointer was put
there, probably a mistake during some merge back in the days...
But this ended up with self_id of libquery data struct still being set
to previous ID pointer, which could randomly generate crap like falsly
reporting indirect data and such, leading to lost reference datablock at
writefile time...
Since we free collection caches when we remap one of their objects, we
also need to tell depsgraph to flush this into the COWs of that
collection, otherwise things like draw code can access freed memory...
There were two issues here, introduced by rB66aa4af836:
* Forgot to change length of some filter_glob var deep in filebrowser code.
* Truncating filter_glob in general can be dangerous, generating
unexpected patterns.
Last point was the root of the issue here, truncating to 63 chars string
left last group as 'match everything' `*` pattern.
To fix that to some extent, added a new BLI_path_extension_glob_validate
helper to BLI_path_util, which ensures we do not have last

By default users want AA in the viewport. For slower systems you want to
be able to turn it off. As in the future we would also like to support
TAA in the viewport we introduced it as a Max Viewport AA settings.

this is actually adding option to add buggy behavior, but.. NPR often
expects buggy behaviors, and its one of the main targets for normal editing.
So think it's reasonable to add that option (disabled by default of

Note that am not really happy with UI, but:
* Not sure where to put it, it's kind of own self-contained area option.
* Don't to make it too much visible, using this should be the exception!
This solves the problem of blocks jumping around when changing modes and
center them to the area (in case of only 2 spacers).

For grouped undo we should not skip the undo push, rather replace the

Before that depsgraph tagging was done from inside notifier listener in

- If there are no viewports, selection tag was not done. Causing possible
issues when object becomes visible.
- Required special trickery to detect which data to tag for update.
- Was causing crash when transforming/selecting markers in clip editor.
This is because selecting marker needed to poke viewport to redraw, since
selected bundles will be displayed differently in viewport.
Moves the preset into a menu for the panel header, so it can be changed

This was causing driver editing popovers to just keep disappearing
whenever you accidentally moved the mouse away, making the popovers
there nearly useless.
After testing with the other popovers we have in other places, I don't
really see why we needed this flag enabled in the first place. You can
still switch between popovers in the topbar by mousing over the others,
and if you want to dismiss without clicking to escape, you can go over a
standard menu instead OR just move back towards the button that spawned it.
Let's just test this out for a while and see how it goes. Maybe we don't
need a more invasive solution here...
There is one legit place in the code where memcpy was used as an
optimization trick. Was needed for older version of GCC, but now
it should be re-evaluated and checked if it still helps to have
that trick.
In other places it's somewhat lazy programming to zero out all
object members. That is absolutely unsafe, at the moment when
less trivial class is used as a member in that object things
will break.
Other cases were using memcpy into an object which comes from
an external library. We don't control that object, and we can
not guarantee it will always be safe for such memory tricks
and debugging bugs caused by such low level access is far fun.
Ideally we need to use more proper C++, but needs to be done with
big care, including benchmarks of each change, For now do
annoying but simple cast to void*.
In C++ it is not really safe to memcpy objects, and newer GCC will warn
about this. However, we don't use our vector for unsafe-to-memcpy objects,
so just explicitly silence that warning.
This support layout.separator_spacer() to be used by headers as a way to
dynamically separate the ui buttons.
Right now no UI file is changed, though we can use this right away in the
timeline, and shortly after in the viewport header (moving settings from
the topbar to it).

This won't ever be used for this operator, as the "edit" operator should
only ever be used for dealign with a single driver - the one under the

While we probably won't be getting a general purpose "Onion Skinning"
overlay anytime soon for meshes, etc. (at least not before the
depsgraph stabilises, and we also get geometry caching working),
for the Grease Pencil integration at least, it makes sense to move
GP objects to using a more general/future-proof solution, instead
of continuing to use a special/dedicated button in the header.
Currently the UI part of this is commented out. Also, the GP branch

The copy/paste driver variables buttons currently only work when used in the

to just hide them for now. Besides, this is probably more of an "advanced"

This fixes the problem where the "Show in Drivers Editor" button would
not actually select and highlight the driver under the mouse.
(TODO: The channels still aren't getting selected properly in the
channels list, but at least the properties show correctly)
Previously, newly created drivers were set to "Scripted Expression"
mode and had their 'expression' field set to the pre-driver value of the
property, so that adding a driver didn't cause the property to immediately
lose its old value (and potentially causing havok in the scene).
However, this had the unintended consequence of making the driver setup
workflow more cumbersome, as you first had to replace that value with
the name of the driver variable before your driver would work.
This commit works around this issue by trying to combine the best of both
worlds (quite literally): Now, the driver expression for drivers created
using Ctrl-D will be "var + <old value>".
Thus, in the simplest case, the driver will do something as soon as you fill
out the driver variable settings (e.g. just filling out the Target Object field
will do it), meaning you get your drivers working faster. Of course, it may now
be necessary to edit out the old-value, and/or it might be a bit more confusing
what/why it's there for newbies. However, the improved ease of setup, and/or
a more tangible example of how an expression may be constructed outweigh the
downsides IMO.
This commit implements a new behaviour for the "Add Driver" functionality
(invoked from the RMB menu on a property, or by pressing Ctrl-D).
Instead of spawning a context menu asking you to pick the way
you want to create a driver, it will now just create a driver on the
property under the mouse and then show the "Edit Drivers" popover so
that you can immediately start editing the properties of this driver.
This way, the whole process is more visual and feels less blocking /
constrained, with less upfront decisions needed immediately.
Notes:
* The new behaviour is equivalent to choosing the "Manually Create (Single)"
and then doing a "Edit Driver" on the property
* Renamed the old "ANIM_OT_driver_button_add" operator to
"ANIM_OT_driver_button_add_menu". It will probably go away
in the near future, but it's better to keep it around for a
while longer still until the new workflow settles down.
The range is 0.25 to 0.75 opacity when the Xray opacity is between 0.0 to 1.0.
This is to avoid loosing completely the sense of occlusion when having no
other solid drawing than the wireframe and loosing the transparency when
xray alpha is at 1.0.
Also replace Bayer (checkerboard) method by interlieved gradient noise to
minimize the chance to loose an occluded line completely.
Other noise function could be tested in the future.
This Fix the problem when multiple objects are selected and one of them
occlude the others. You cannot see clearly what is selected.
With this option, selection is more clear when Xray mode is enabled.
By using equation 7 from the paper, we make the surfaces nearest to the
viewpoint appear more "opaque". This gives better sense of ordering than
the previous weighting function that was really not doing anything.
There was a method explained in the Weighted Blended Order-Independent
Transparency paper to support hardware that does not support per render
target blending function.
So now only 2 geometry passes are required instead of 3 (one being the
outline/depth fill pass).
This also fix how the blending is done. There was some premult confusion
in the implementation.
As in Pose Mode, the idea here it to try to reduce viewport complexity
without requiring users to turn off the overlay completely all the time.
For example, a background prop (e.g. a tree with a tyre hanging off it,
or a branch with hand-placed leaves) won't be cluttering the viewport with
its relationship lines all the time, when you're trying to do something else.
When you really do need to see these lines, you can still select the object
in question, and you'll see the lines for which objects are its children
or what its parent is. And to see all lines, you can still always select all
objects.
This patch reduce the branching in the lamp loop, improving compilation time
noticeably (2372ms to 1785ms for the default shader).
This should not change the appearance of the shader.
Performance impact is negligeable.
This mimics the 'spreadsheet' behavior. Columns and/or rows can have
equal sizes, or adapt to their content - but always in a grid way (i.e.
all items in a same column will always have same available width, and
all items in a same row will always have same available height).
Also, you can fill (order) the grid in a row- or column-major way.
Not used anywhere for now.

This fixes the problem that matcaps have when using a very larg FOV in
perspective view.
This was because it was stupidly using the normal direction which can not
aligned with the view vector under perspective.
So to workaround this problem we don't use the normal as is, but compute
how much it's facing the camera.
This changes how matcaps looks in perspective because they now always use
the full range of the matcap (which is expected).
Pretty straightforward changes, merely mimicking dm-related code,
which was already essentially using either Mesh or BMesh data to
build the PBVH...
Note that we "lose" the subsurf (a.k.a. grid) PBVH case here, but that
one was already dead code in current blender2.8, since final dm is
always a cddm built from evaluated mesh.
Proper fix is pending new code for subsurf/multires area.
Would try to use data from global area for the newly created fullscreen area.
This should not happen, so instead of a global area use first area from layout.
When a CacheFile datablock is copied to an in-main datablock, it means that
the new copy should be independent of the old copy. In this case certain
properties are reset/duplicated. When it is copied to a no-main datablock,
we assume this is a copy-on-write copy that's used for evaluating things,
in which case the handle and object paths are referenced instead of
reset/ duplicated. This prevents us from re-opening the Alembic file every
time a new CoW copy is made.
The same approach is taken when freeing data (only when an in-main datablock
is freed do we actually free the data).
This makes evaluated objects to point to a non-evaluated collection,
which is already really bad. What is even more worse, objects in those
collections are not evaluated either.
Proper solution would be to implement visibility flag for nodes, which
will be set to 0 for transform/geometry components, but which will be
1 for copy-on-write components.
This way we will guarantee consistency of dependency graph.
For now this change is good enough and unlocks production.

I cant test if XIM works,
but this isn't useful to send double events, so disabling for now.
Since we are only creating this and never updating, there is no need for
the original approach with the individual data to be updated.
Note we only populate the GPU data when binding the UBO, so we can in the
future easily create the UBOs in a separate thread than the main drawing one.
Also at the moment animated materials are not working. To fix that we need
to free/tag for free the GPUMaterials in BKE_material_eval.
This make the limited wireframe not a performance problem anymore.
However, this does change the number of edges displayed as the threshold
is now computed per vertex instead of per edges.
For this reason we extended (internaly) the range of the slider so that the
users can hide more edge.
Before that copied collection in copy-on-write were running out
of sync with original ones. This was causing crash with the
following scenario:
- Delete some objects from scene
- Add particle system to an object
- Change particle mode to Hair
Thanks Dalai for debug session! Pair programming ftw!
We now remove the shader for every update.
So at the moment the whole point of UBO (Uniform Buffer Objects) is that they
are more efficient than individual uniforms.
Next steps is a harmless refactor to stopping UBO from referring to original
data in the UBO, and simply copying it.
It would also be interesting to make the final shader more granular as far as
the library and required functions are concerned. Even if this doesn't impact
performance, it should give us smaller easy to debug shaders
(a simple shader now has > 5k lines!).
If performance for animated values is measureable slower after this commit we
can port the shader creation CPU side to the depsgraph - localizing the tree,
hashing, lookup, ...
Additionally we can stick to update the UBO when the material changes but not
its topology. This is very trick because of localized trees. So we will only
re-visit this if profiling hints at any benefit from it.
Notes:
* Really need to address RNA setters case, end up adding way too much
G.main here these days... :/
* Added Main pointer into bAnimContext, helps a lot in anim code ;)
When calling the bpy.ops.poselib.apply_pose() operator from Python, Blender
would deadlock when the rig has drivers.
Similar BPy_{BEGIN,END}_ALLOW_THREADS calls were already in place in the
rna_Scene_update_tagged() function.
This is part of the work needed to refactor the material parameters update.
Now the gpupass cache is polled before adding the gpumaterial to the
deferred compilation queue.
We store gpupasses in a single linked list grouped based on their hashes.
This is not the most efficient way but it can be improved upon later.
Not sure why exactly it is called a cleanup, the code was much more clear
and robust against possible missing return statements which are MANDATORY.
Missing return statement will:
- Cause two different BVH traversals to be run.
Not is happening currently, but if more BVH layouts are added, it will
become a problem.
- It is already causing assert() statements to fail, since functions are
no longer returning when they are supposed to.
If there is any measurable reason to keep this change, let me know.
Otherwise just stick to reliable/tested/robust code.
This reverts commit ba65f7093b.
The issue is that children drawing is done by object mode,
which operates with data from evaluated context. But that
data needs edit mode's cache to be properly updated first.
Makes ADD brush to work.
At some point children particles draw got broken, children are not
visible for until first stroke is done. Still looking into it.
Experiment: let the user be in control of the alpha channel as some rigs
are hard too see during bone selection. Especially rigs that were
designed for 2.79 wireframe mode.
That bug was also likely affecting other cases - basically it was making
auto-keying always key from evaluated ('visual') values, never base,
data values... Added a flag, in some cases we do want evaluated values
here, obviously.
This was no longer working, now this works the same way as
scene.update(), only it applied to the current view layer.
Caused crash running alembic export from Python.
A cavity shader based on SSAO. Works on all workbench deferred passes.

The mutex was shared between CoW copies of the CacheFile datablock, and
as a result also freed multiple times. It is now only freed when the
original datablock is freed; the CoW copies share the same mutex.
This is a beginning of series of commits which will clearly separate
building IDs which are used as object data from object building.
The goal is to be able to always build whatever ID. Required to make
driver targets to work reliably with copy-on-write concept.
DATA datablock must evaluation must never depend on object it is
used for. If there is something what depends on an object, it must
be done on object level.
At least the actual callback was empty.
When the source mesh doesn't have the primary layers (CD_VERT for vdata,
etc.) the returned mesh also didn't have those layers, even when non-zero
elements were requested (for example requesting 4 vertices would still
result in mvert = NULL).
The ObjectID pass was generating per material per dupli a specific
number for the outline what results in a GPU context switch. In spring scene
01-050 a scene with many trees (duplis) generated 28000 GPU materials.
Now only new materials are created when objectid pass is enabled. Also
added a hard limit to the number of objects for the objectid pass (255)
Basically the outline between objects will not be drawn, but it will be
very hard to detect them also.
Also fixed for XRay mode.
Test this since the popup feels disruptive/flashing when its too large
when set smaller it looks closer to a menu w/ key-accelerators which is
the intention in this case.
It's also more likely the active tool can be placed under the cursor.
The recent change also used the buildtools instead of the regular compiler, you now have to explicitly state what you want to use :
2017 - the standard msvc compiler
2017pre - the msvc compiler from the preview installation
2017b - the msvc compiler from the buildtools installation
The function definitions still reside in DerivedMesh.c. Once we're done
porting all the DerivedMesh use to Mesh, we'll move the still-relevant
functions to mesh_runtime.c. This move is now cumbersome due to shared
statically-declared utility functions in DerivedMesh.c
This helps making things clearer and cleaner. Func returning filepath of
G.main is separate, so that we can easily track its usages, and
hopefully deprecate it at some point. Though that usage of G.main is
likely the less evil one, you nearly always want current blendfile path
in those cases anyway.
When run from make.bat the environment is setup correctly and the VCToolsRedistDir environment variable exists, on later invocations of cmake this may no longer be the case and a warning was emitted about the missing runtime. we can't rely on InstallRequiredSystemLibraries.cmake here since it uses the compiler version to figure out the correct location and it doesn't know how to deal with clang.
Manipulators which aren't explicitly activated via tools are now hidden.
Tool manipulators are kept because it doesn't make sense to interact
with a tool with hidden manipulators.
Material slots are a real pain to get working, due to all the black
magic they do to hide object vs. obdata storage of the material...
Currently hitting an order problem - we need to always set 'link' (to
object or obdata) property of the slot first, before we set its
material... *super-sigh*
- users can use their own matcaps
.config/blender/2.80/datafiles/studiolights/matcap/ folder
- upto 100 matcaps can be loaded
- color of the matcap is influenced by the color of the material/single
color etc. To show the plain matcap use single color at 1.0
- chosing a matcap is at lighting level (flat/studio/matcap)
- matcap only possible in solid mode
- also works for X-Ray mode
As the old matcaps are still in used by the clay engine I didn't remove
it yet.
We are already running out of available flags in main, generic int, and
everytime I work on static override I find new special cases that will
need new specific propflag, so...
Switching the mode was being done per object,
where it should first check all pose bones from all objects.
This also removes code that changes the transform mode
from within the counting function.
This was only needed on transform initialization.

Related change: made it (hopefully) more clear name for flags.
Non-manifold geom was producing inverted result when the camera was inside
the shadow volume.
When rendering non manifold geometry with the depth fail method, we need to
emit the cap as if it was the same geometry with a virtual thickness.
Another way to view it is to imagine having a set of non-manifold geometry
all facing the light.
So for every tri we emit a front cap oriented toward the light and the
back cap pointing away from it (whatever the actual orientation of the tri).
Extrusion pass stay the same as the depth pass method (double the increment
if it's a manifold edge).
In the Python API, any panel becomes a subpanel by setting bl_parent_id
to the name of the parent panel. These subpanels can contain advanced or
less commonly used settings.
Now hairs are shaded properly in workbench and support texturing.
I also added a 10% random normal direction per hair to have a bit more
variation in the shading. This is hardcoded for now.
-expanded build_deps.cmd with 2017 support, it can't locate msvc2017 so needs to be run from developer prompt.
-Newer cmake was unhappy with openal's cmakelists.txt
-collada has warning as error on and errored out on new msvc2017 warnings.
This is a dirty fix. A bit more cleaner approach would be to check if a
context is bound and delay the deletion only in this case.
Also we may want to do this orphan deletion at some other places than
wm_window_swap_buffers.
Do note that it does not match cycles implementation.
Also we could precompute the hash per strand before rendering but that would
suggest it's not per engine specific.
If we make the random value internal to blender then it won't be a matter
because other renderers will have access to the same value.
This is really convenient for development. Either for profiling the
generated shaders or to check if the generated code is correct.
It writes the shaders to the temporary blender session folder.

By default when moving a edge of the screen it always snaps to an invisible grid with unit of 4 pixels.
This was also affecting the snap to the midpoint and adjacent.
The solution was to make the snap to areagrid optional and use values of `origmin` and `origsize` that match the transformations in screen_edit.c.
The fix bit is the split.
But since we are using col.separator() left and right we need this as well.
I still don't think the separators are the way to go, yet may as well be
consistent with the current design in place, thus the extra separator here too.
This commit restores support for Motion Path drawing in 2.8 (as it wasn't ported over
to the new draw engines earlier, and the existing space_view3d/drawanimviz.c code was
removed during the Blender Internal removal).
Notes:
* Motion Paths are now implemented as an overlay (enabled by default).
Therefore, you can turn all of them on/off from the "Overlays" popover
* By and large, we have kept the same draw style as was used in 2.7
Further changes can happen later following further design work.
* One change from 2.7 is that thicker lines are used by default (2px vs 1px)
Todo's:
* There are some bad-level calls introduced here (i.e. the actgroup_to_keylist() stuff).
These were introduced to optimise drawing performance (by avoiding full keyframes -> keylist
conversion step on each drawcall). Instead, this has been moved to the calculation step
(in blenkernel). Soon, there will be some cleanups/improvements with those functions,
so until then, we'll keep the bad level calls.

Since the viewport header now supports transparency, text on pulldowns
can be hard to read if their color matches the viewport content.
Background is drawn using the 'inner' theme color, that was unused until now.
In some heavy rigs matrix inverse can be 10% of computation time. This
reduces it to 2% by using Eigen's optimized 4x4 matrix inverse and SSE

Note there is some talk about changing the position of this (which would be strange in the image editor by the way,
since there we use the bottom for the result of the current pixel when dragging the mouse).
However first I wanted to fix this regardless.
This currently shows panels that were in the 2.79 3D view toolbar
which are now popovers.
In some cases it's useful for these to stay open.
This commit adds a space type to do this.
Note this is currently empty in object mode.
This will currently only work for the RelWithDebInfo configuration since asan
does not support the debug crt. for source line information in the reports,
you need a copy of llvm-symbolizer in the blender folder or set the

6.0.0) llvm-symbolizer does not ship with the binary clang/llvm distribution.

This overlay is showing mesh topology. It is usable with transparency
even if the mesh order can mess up with the expected result (some object
more prominent than others).
Edge thickness and alpha values are hardcoded for now but can easily be
added to theme or object settings.
Only OB_MESH is supported for now.
Creates a simple index buffer with negative indices if the edges is not a
real edge.
Also create the buffer texture representation of this buffer along with the
pos_in_order buffer texture.
This includes:
- Skip OB_RECALC_TIME tag from object duplicate operator
not sure why it is needed: even if original object was
animated, duplicating it will copy evaluated values.
- Don't tag whole ID for update when updating it after
relations rebuilt. Use the same trickery to detect
whether animation is to be re-evaluated or not as is
done for update flag=0.
- Don't tag datablocks which are expanded for update
of copy-on-write.
- Avoid flush along relation from copy-on-write
operation in action. This will not invalidate any
pointers in the copied datablock since we don't
reference anything in the action.
Will cause some bad behavior when object is shared across multiple
visible view layers with different overrides. Accept it for now,
and possibly force single view layer later.
When active dependency graph is evaluated, it will apply animation,
drivers and scalar evaluation data (such as object matrix) to an
original datablock. This way operators and tools can easily read
data from original datablock.
This will simplify porting them to copy-on-write, and solve issues
when some operator will allocate new datablock based on original one,
and will want to read data from it.
This way we allow animation system to make decisions based on which
context dependency graph is coming from, and whether it belongs to
an active edit window or not.
After discussion with Sergey and Dalai, we have decided to remove
this option completely. We're getting to the point where it is almost
impossible to really use 2.8 without COW, and keeping the old option
running ends up diverting dev resources away towards tracking down
and fixing problems with a parallel system that will be going away.
Made the highlights darker (using the defaults of blender 2.7
- sharpness = 50
- spec color = 0.025 (I bumped it to 0.1)
- added a log2 to the frontal camera light to reveal more details of the
mesh
We no longer user scissor for 3D viewport drawing, and some selection
code assumed it still. This also cleans up unnecessary scissor test
switching, we only have it temporarily enabled now.
* depsgraph.ids: all evaluated datablocks in the depsgraph

After more testing, I realised that bendy bone properties should also be grouped,
but probably all other per-bone settings too. Now, just group all of them, since
it's easier for everyone this way.
For many years, animators have been complaining about how keyframing a (transform)
property directly would leave them ungrouped, while keyframing them using a Keying Set
would put them into a group based on the name of the keyingset.
This commit attempts to improve (unify + make consistent) the default behaviour:
* All object transforms now get added to an "Object Transforms" group,
regardless of whether they were added individually via buttons or keyingset
* All bone transforms now get added to a group corresponding to the name of the bone
instead of only the ones added via keyingset
Saves quite a bit of CPU ticks per mesh update, giving measurable
speedup for file from T55228.
Memory usage goes up a it, most likely due to evaluated mesh having
more custom data layers than corresponding DM does.
This introduces a new depsgraph API for getting updated datablocks,
rather than getting it from bpy.data.
* depsgraph.ids_updated gives a list of all datablocks in the depsgraph
which have been updated.
* depsgraph.id_type_updated('TYPE') is true if any datablock of the given
type has been added, removed or modified.
More API updates are coming to properly handle multiple depsgraphs and
finer update granularity, but this should make Cycles work again.
Use the same key for pose & weight paint mode (instead of texture paint)
This makes more sense since pose/weight paint modes
are often used in combination.
This mean you can store data used for drawing inside the object engine
data.
Also fixes T55243 Crash in ASAN debug builds due to use-after-free memory in draw code - instances issue?
This now can shade actual poly strips that mimics cylinders.
This makes hair coverage exact compared to the line method and result in
smoother fading hair.
This does make the sampling a bit more exact but needs more samples to
converge properly.
This new system use transform feedback to compute subdivided hair points
position. For now no smoothing is done between input points.
This new system decouple the strands data (uv, mcol) with the points
position, requiring less update work if only simulation is running.
In the future, we can have compute shader do the work of the feedback
transform pass since it's really what it's meant to. Also we could generate
the child particles during this pass, releasing some CPU time.
draw_hair.c has been created to handle all of the Shading group creations
as well as subdivision shaders.
We store one final batch per settings combination because multiple viewport
or render could use the same particle system with a different subdivision
count or hair shape type.
Hair Particles shape properties are ported from cycles. Thoses properties
have the same defaults and have a do_version of their own. Cycles will use
theses properties instead of its custom ones.
Some realtime engine specific settings are also added to scene->r because
it's much easier to control as global values.
Bumping Version number so cycles can do its own do_version on top of the
default settings.
This mimics the behaviour of DRW_shgroup_empty_tri_batch_create and will
replace it eventually.
The advantage is that it's compatible with transform feedback.
Modifiers stack only get COW/evaluated IDs, so no need to go auery again
DEG for those. Further more, now unified handling of EditBMesh case (was
done on case-by-case basis in a few modifiers, not all for some reason).
We are still missing the ability to get final and cage deformed meshes
when in Edit mode though, this is to be defined/implemented in depsgraph.
This is a first step to have correspondence of legacy derivedDeform
within a new formulation. Only base ground for now to support file
reading, copy-on-write remapping and such.
Support switching non-active objects in/out of a mode from the outliner.
- This allows users to change which objects are in a mode w/o
having to exit the mode and change seleciton.
- Changing the mode of the active object applies to all other objects.
- By convention setting a mode selects, removing de-selects,
this is done for convenience so switching to a mode from object mode
maintains the set of objects in the current mode.
See: T55246
- Use Tab key for search.
- Number keys switch modes.
- The number of the current mode can open a submode menu
(currently only works for edit-mode)
- Ctrl-Tab, Ctrl-Shift-Tab - cycle workspaces.
There is a chance parts of Blender call BKE_object_workob_calc_parent
with ob->parent objects that are outside the depsgraph.
This we can tackle later since these are corner cases anyways,
and this fix fixes all parenting operators in Blender.
This commit fixes a problem the Spring team were having in the shot files 01_030/050 with
the camera rig, where when you tried grabbing/translating the bones of the camera rig,
they would only keep rotating/scaling instead.
The reason for this is that with the multi-object editing support added into the transform
system, this code would now get run for all the other objects that were being included
in Pose Mode, even if no bones from those armatures were selected. Since no valid translatable
bones were found in those other armatures, the transform mode would get reset upon
encountering one of those other bones.
Scene lights are rendered when
- v3d is not available
- or shading type is other then OB_MATERIAL
- or shading type is OB_MATERIAL and use_scene_light is true

This is a hacky fix so that animators can use this tool again with autokey enabled
(which they do all the time). The issue here is that the tool writes the new (0)
values to the original data, but insertkey now reads from evaluated data (so that
keying interpolated values works). However, the cleared values do not get re-evaluated
or flushed before insertkey gets to it (via auto keying), meaning that the wrong values
get keyed.
There may be better solutions for this, but for now, this is the simplest fix that
I can get working.
More MessageBus-related silliness to resolve issue with toggling visibility/mute/locking
status of F-Curves/Groups/etc., as well as other things like modifying active keyframe's
values, or changing properties of F-Modifiers.
I've now ended up just whitelisting in the region subscribers all the animation-related
structs in RNA. But still, that may not be enough to deal with potential issues later
with the property sliders (shown per channel, optionally), which can come from anywhere.

This patch adds support for IES files, a file format that is commonly used to store the directional intensity distribution of light sources.
The new IES node is supposed to be plugged into the Strength input of the Emission node of the lamp.
Since people generating IES files do not really seem to care about the standard, the parser is flexible enough to accept all test files I have tried.
Some common weirdnesses are distributing values over multiple lines that should go into one line, using commas instead of spaces as delimiters and adding various useless stuff at the end of the file.
The user interface of the node is similar to the script node, the user can either select an internal Text or load a file.
Internally, IES files are handled similar to Image textures: They are stored in slots by the LightManager and each unique IES is assigned to one slot.
The local coordinate system of the lamp is used, so that the direction of the light can be changed. For UI reasons, it's usually best to add an area light,
rotate it and then change its type, since especially the point light does not immediately show its local coordinate system in the viewport.

If the object is manifold and the camera is in the shadow side, we can
use the depth fail method to fix the inverted shadow glitch.
Unfortunately this does not really work for non-manifold.
Implementation details:
We try to be as efficient as we can, we precompute camera near plane
projected into 2D shadow space so we can test for intersection with the
shadow boundbox easily.
As the intersection test is done in 2D it's pretty fast.
Unfortunately, this means the shadow bounds are all aligned to the same
space and are not the smallest bound we could extract.
This new API aim to provide simple function that can be called by the draw
engines during any phase of the draw pipeline. All calls are saved and

The problem was that the particle system modifier was reading ob->derivedDeform
during modifier stack evaluation. Due to the mesh -> DM conversion this was no
longer set leading to wrong results.
In fact we don't really need the deformed mesh, just the original mesh topology
for face/poly index remapping. So the solution is to use that instead.

The registry hack we were using wasn't very reliable, the recommended way to locating visual studio is using vswhere (15.2 and up), using it also allows to switch between the regular and pre-release versions.
Just as with my earlier fix for bones (0492e56fec),
here we're reading evaluated object values into the "i" versions of each transform
property, and using the original/non-evaluated data for the pointers.
XXX:
What's not clear though is what we should be doing with the "BKE_object_where_is_calc()"
calls here. They currently use ob, but that probably shouldn't happen... and ob_eval
should in theory have a more up-to-date version of what it would need to evaluate!
* Added BKE_object_get_evaluated_mesh, which can also be used outside of
Modifier context.
* BKE_modifier_get_evaluated_mesh_from_object is now a dummy wrapper
around BKE_object_get_evaluated_mesh, we do not need anything special
anymore for RENDER quality option, since this is supposed to be handled
at depsgraph level... Maybe we can get rid of it at some point, but kind

* Always use BKE_id_new, unless you have a very good reason to use
lower-level code!
* Prefer to pass actual ID user pointer to functions like id_us_plus & co,

who is the user we increase count for!
Don't store pointers to ViewLayer in the workspace, only names. Add specific
relation type since the generic mechanism makes the code hard to follow.
Integrate with pointer restore for undo and library remapping code to avoid
data going out of sync.
Also add relation automatically if there doesn't exists one yet in
BKE_workspace_view_layer_get, because in general it's really hard to ensure
it will exist when making arbitrary scene changes.

These needed to be using the COW evaluated data, instead of the raw bone
positions.
All other datatypes still need converting to work with this though.
The GPU kernel needs to use atomics for accumulation since all offsets are processed in

This commit adds a new menu entry - "Edit Driver" - the RMB menu that
will show a popover panel displaying the settings for the driver you
activated the menu item on. This shows the popover panel defined in
yesterday's commit (GRAPH_PT_drivers_popover).
It is possible to edit the driver settings from this panel now.
However, do be warned that the functionality presented is highly
WIP still. There are some unresolved issues, such as:
- The popover disappears too easily on any mouse movements/clicks
on anything, making the panel less useful right now than it should.
- The layout still needs refining. Currently the layout that's there
is a bit of a placeholder until we can play around with it a bit
more to see/feel what feels good/right or what is too much.
- The "Open Drivers Editor" on the bottom of the panel doesn't work.
There are some tricky context tricky things that need to happen here
to make that case work, since the operator button won't have the necessary
context info.
The Math node currently has the normal atan() function, but for
actual angles this is fairly useless without additional nodes to handle the signs.
Since the node has two inputs anyways, it only makes sense to add an arctan2 option.

The implementation is pretty straightforward.
In Cycles, sampling the shapes is currently done w.r.t. area instead of solid angle.
There is a paper on solid angle sampling for disks [1], but the described algorithm is based on
simply sampling the enclosing square and rejecting samples outside of the disk, which is not exactly
great for Cycles' RNG (we'd need to setup a LCG for the repeated sampling) and for GPU divergence.
Even worse, the algorithm is only defined for disks. For ellipses, the basic idea still works, but a
way to analytically calculate the solid angle is required. This is technically possible [2], but the
calculation is extremely complex and still requires a lookup table for the Heuman Lambda function.
Therefore, I've decided to not implement that for now, we could still look into it later on.
In Eevee, the code uses the existing ltc_evaluate_disk to implement the lighting calculations.

This reverts commit b4b745b720.
This was causing a problem in 01_025_A.anim.blend from the Spring
production files, where selecting one of Autumn's bones would
result in character jumping back to the origin.
Note the relationship we need is from the geometry/object to the curve data,
not the curve object.
Related to T55167, though when copy-on-write is enabled, we still get a crash.
Otherwise, it's not clear where things are coming from.
FIXME: The icons for datablocks may not always be correct. It uses the
innermost struct's icon instead of the datablock's icon - e.g. Bone
vs Object/Armature. But, that may make more sense for users?
The idea is that we may be able to just take this code and put it into a
new popover panel that gets displayed when called from the UI. This should
at least work well for a first pass test of what we want this UI to look like.
In theory, this should mean that we can get rid of the "Update Dependencies"
button. In practice, there may still be cases where it's still needed
(as somehow, it did end up being needed in the past, even though the RNA
calls should in theory be doing everything needed already).
There are multiple other ways to do it. Leaving this here just made it
easy (and dangerous) to accidentally remove the driver, and was causing
other problems with other layouts.
* Remove "Show Debug Info" option. Everyone has it turned on all the time,
since it's just useful to have
* Make the "Remove Driver" button less prominent. It doesn't happen that much,
so it shouldn't take up as much room
* Make "expressions" textbox wider (i.e. taking up the whole column width)
by separating the label and textbox on separate lines.
* Rename "Add Variable" button to make it clearer to users what "variables"
may be (i.e. they serve as a way to specify Inputs, just like adding a
"Source Data" node in a nodetree)
* Regroup buttons
This is intended to help developers to know how and when to use each shader.

Unmultiplied the final color during compositing. Same as the revealage
buffer would do
Also use the DRW_STATE_ADDITION_FULL as it is aware of premultiplied
colors
The modifier is still quite slow; this could be due to caches being written
to a CoW datablock instead of the original one. More investigation is
needed.
Logic here was a bit broken.
1) We need to send updates even when deselecting bones, not only when we
actually end up select then.
2) Also, when bones are locked for "selectability", they should not be able
to be deselected.
To bring the UI more in line with the proposed design in T54653 for the "Add Drivers"
popup panel (NOTE: this is separate from the "Drivers Editor", in previous commit!),
this commit adds a new panel - "Driven Property" to the Drivers Editor UI.
This basically duplicates the "Active F-Curve" panel (with less options)
to make it easier to see at a glance which property the Drivers Editor is
showing you.
This commit adds an operator, "Show Drivers Editor", to the RMB menu when
clicking on properties.
As per T54653, this will open a new Graph Editor instance in a new/separate
window (much like how the User Preferences show up in a popup window now),
and will configure all the relevant panels so that you can see and edit the
driver settings immediately without doing a lot of the view configuration steps
that were previously needed.
When doing so on a property that is driven, the driver/fcurve for that property
will be made active in the editor, ready for you to start editing its settings
without having to hunt it down again first.
Allows more than one snap mode to be enabled. So different combinations are possible.

Only show hierarchy relationship lines when bone or its parent is selected.
This cuts down the clutter visible in general when relationship lines are
enabled (currently they can't be disabled), which should make it more useful
to keep them on (e.g. constraint lines/hints can still be drawn this way).
As was decided at today's dev kickoff, we're now moving to having
Copy-on-Write enabled by default, as 2.8 is barely functional with
it off.
To run Blender *without* COW (e.g. for testing), use:
--disable-copy-on-write
You need the whole chain of pointers... This was breaking static
overrides of any rig basically.
Note that this kills performances again (adding several hundreds of
thousands more stuff on a blendrig...), need a better way to handle RNA
override walking.
Fixes camera view locking, camera related transitions and movements with the active object as pivot point
Note there can still be problems if the active object is not selectable
Seriously... Not all edges have faces!!!!!!!!
Quick fix to make it possible to load/use customshaped bones again, not
100% sure it is correct, but... At least it does not crash anymore!
- This allows quick, consistent toolbar access
w/o conflicting w/ the keymap.
Where pressing space before a key activates that operator as a tool
instead of running immediately.
- Search can still be accessed by pressing spacebar again.
- When there is no toolbar for a space, operator search still opens.
If a mesh is known to be manifold, then it's not necessary to increment the
stencil buffer 2 times anymore. But we still need to account properly for
degenerate triangles.
In this case, only generate a quad if the tri is facing the lamp. If there
is a degenerate loop, the other edge will either cancel the increment (if
it is also facing the light) or not produce a quad (if not facing).
This will always give the correct count.
Seems that degenerate tris are somewhat widely used in modeling. So we need
to fix this. Test the edges in the geom shader since the adjacency info is
only dependant on topology, not actual vertex placement.
This fixes most of the remaining noise issues. Only a few artifacts appear
on really weird models. So if you want to get rid of the artifacts, fix
your model!
This makes the shadows ~10 times faster in the general case.
This only create extrusion geometry on the outline edges. Also we increment
or decrement the stencil buffer by 2 for each manifold edge and only by 1
for non manifold. This make the algorithm robust yet less heavy than creating
one prism for each triangles.
Operators did not suffer from this problem as they were still just using notifiers
directly. The "proper" fix is to use the new message bus system. But, we've
got enough problems dealing with COW already as it is now... moving on.
The transform code needed to use data from the "_eval" copy of the posebone
instead of the main-db version, otherwise the initial/reset value would be
wrong, causing the jumping.
Without the exception, adding new poses to pose libraries took several seconds
with only <= 4 bones selected. While we may still need this for other cases too,
since bones are such a common use case, it makes sense to provide some level
of optimisation for them.
This now works by getting the RNA Path from the given PointerRNA to go from the
ID block to the data it points to, then uses this path to find the new data
relative to the COW ID.
Note: This currently still has all the debug prints left in - As can be seen,
I was testing this against the earlier PoseBone hack/special case. We may still
need to bring such special cases back in future, since looking up RNA Paths
like this can be slow.
When using copy on write, insert keyframe operators were reading from old
bmain data instead of COW data. This meant that inserting keyframes would
often read old/stale data, resulting in invalid keyframes getting created
(e.g. from last transform operation, instead of actual current state).
This commit makes it so that keyframing operators will ask depsgraph for
the evaluated copy of the data, so that it can read values from that. It
introduces a new function - `DEG_get_evaluated_rna_pointer()`, which when
working correctly/fully, should work just like the other `DEG_get_evaluated_*()`
functions, except it lets you pass in an RNA Pointer.
However, currently, this is only done for Pose Bones (as a dirty hack, since this
is an important/pivotal requirement for production) and/or datablock
properties directly (since we can just use the DEG_get_evaluated_id() directly).
on the datablock.
Committing to a branch for now as this all needs more testing. More work to come
later at a more sane time of day!
Experimental support for using popovers like menus,
use this when the user hold the mouse down
(previously this did nothing).
This means turning frequently accessed menu items into
popovers doesn't add more clicks to the existing use case.
There are still probably other massive problems to solve (i.e. which copies
of data cache/sim gets written/read from for COW eval) that need to be solved
before we can get the sims actually running though.
This adds Eevee render tests using the Cycles files. Currently it must
be enabled by setting WITH_OPENGL_RENDER_TESTS=ON. Once we have reference
images we can enable it by default.
Some of the Cycles and Eevee tests are also currently broken due to

Differential Revision: https://developer.blender.org/D3182
OVERVIEW
* In 2.7 terminology, all layers and groups are now collection datablocks.
* These collections are nestable, linkable, instanceable, overrideable, ..
which opens up new ways to set up scenes and link + override data.
* Viewport/render visibility and selectability are now a part of the collection
and shared across all view layers and linkable.
* View layers define which subset of the scene collection hierarchy is excluded
for each. For many workflows one view layer can be used, these are more of an
advanced feature now.
OUTLINER
* The outliner now has a "View Layer" display mode instead of "Collections",
which can display the collections and/or objects in the view layer.
* In this display mode, collections can be excluded with the right click menu.
These will then be greyed out and their objects will be excluded.
* To view collections not linked to any scene, the "Blender File" display mode
can be used, with the new filtering option to just see Colleciton datablocks.
* The outliner right click menus for collections and objects were reorganized.
* Drag and drop still needs to be improved. Like before, dragging the icon or
text gives different results, we'll unify this later.
LINKING AND OVERRIDES
* Collections can now be linked into the scene without creating an instance,
with the link/append operator or from the collections view in the outliner.
* Collections can get static overrides with the right click menu in the outliner,
but this is rather unreliable and not clearly communicated at the moment.
* We still need to improve the make override operator to turn collection instances
into collections with overrides directly in the scene.
PERFORMANCE
* We tried to make performance not worse than before and improve it in some
cases. The main thing that's still a bit slower is multiple scenes, we have to
change the layer syncing to only updated affected scenes.
* Collections keep a list of their parent collections for faster incremental
updates in syncing and caching.
* View layer bases are now in a object -> base hash to avoid quadratic time
lookups internally and in API functions like visible_get().
VERSIONING
* Compatibility with 2.7 files should be improved due to the new visibility
controls. Of course users may not want to set up their scenes differently
now to avoid having separate layers and groups.
* Compatibility with 2.8 is mostly there, and was tested on Eevee demo and Hero
files. There's a few things which are know to be not quite compatible, like
nested layer collections inside groups.
* The versioning code for 2.8 files is quite complicated, and isolated behind
#ifdef so it can be removed at the end of the release cycle.
KNOWN ISSUES
* The G-key group operators in the 3D viewport were left mostly as is, they
need to be modified still to fit better.
* Same for the groups panel in the object properties. This needs to be updated
still, or perhaps replaced by something better.
* Collections must all have a unique name. Less restrictive namespacing is to
be done later, we'll have to see how important this is as all objects within
the collections must also have a unique name anyway.
* Full scene copy and delete scene are exactly doing the right thing yet.

Without this we need to have the context to get the
(space_type, mode) args for an active tool lookup.
For event handling & poll its more convenient to have direct access.
This piece of code remains annoyingly verbose, but at least now we do
not have anymore twice the same logic duplicated between single array
element handling, and non-array properties.
This patch adds support for:
- Per space-type tools (3D view and edit).
- Per mode tools (object, edit, weight-paint .. etc).
The top-bar shows the last activated tools options, this is a design
issue with using a global topbar to show per-space settings.

We handle doversion for the scene properties, but not for the
view layer overrides.
Overrides will be implemented in a different way via dynamic overrides.
For now this data is completely lost.
For now, do not override/instantiate objects used as boneshapes.
Note that this is a rather poor/dirty hack, it seems Spring char groups
still have a lot of other (unused???) shape objects.
Ideally lib groups should be designed more cleanly for the new Static
Override system, putting only really usable objects into 'main' group,
and placing the others in sub-groups, helpers groups, or so...
*Always* use BKE_library API to handle IDs allocation and freeing,
unless you have a very, very, very good reason not to do so - and
perfectly know what you are doing.
No idea why that was working this morning, now we do not get CoW tag
anymore (which kind of makes sense since it's set *after* copying
happens...), so just resorting to using the NO_MAIN flag instead.
This is a usefull feature that can be used to do a lot of precomputation on
the GPU instead of the CPU.
Implementation is simple and only covers the most usefull case.
How to use:
- Create shader with transform feedback.
- Create a pass with DRW_STATE_TRANS_FEEDBACK.
- Create a target Gwn_VertBuf (make sure it's big enough).
- Create a shading group with DRW_shgroup_transform_feedback_create().
- Add your draw calls to the shading group.
- Render your pass normaly.
Current limitation:
- Only one output buffer.
- Cannot pause/resume tfb rendering to interleave with normal drawcalls.
- Cannot get the number of verts drawn.
Patch D3205 by Kanzaki Wataru
Only implemented in Eevee for now. Collapse a closure to RGBA so we can
do NPR stuff on the resulting color.
Use an emission shader to convert the color back to a closure.
Doing this will break PBR and will kill any SSR and SSS effects the shader
the shader rely on. That said screen space refraction and ambient occlusion
are supported due to the way they are implemented.
There are a few places where DerivedMesh is still used, most notably
when calling the (not yet ported) cloth simulation. There is also still
the use of Object.derivedDeform and Object.derivedFinal. Those places are
marked with a TODO.
Some functions in the editors module were copied to accept Mesh. Those
already had 'mesh' in the name; the copies are suffixed with '__real_mesh'
for easy renaming later when the DM-based functionality is removed.
Locked bones of proxies should not be editable, at all. But lack of
update from linked rest pose in 2.7 allows to pose and animate locked
bones (not to pose them without animation though, or you'd lose your
pose on next file save & reload).
this is used by artists to always lock all their bones in a rig, so that
proxies fully update when lib rig is modified...
For now, restore that broken behavior in 2.8 by not updating proxies
against lib armature in CoW context (makes sense anyway, we are
currently doing a lot of useless thing when copying data for depsgraph
evaluation!).
This patch adds support for clip_planes (ie ignore what is behind a face)...
The idea is to first execute a raycast to get the polygon to which the mouse cursor points.
Then a snap test is done on the vertices or edges of the polygon.
Then with the normal and location obtained in raycast a new clip_plane is created and the snap over the whole scene is processed ignoring the elements behind the clip_plane.

Doing that copy is the right thing, but only if the mesh has its own
deformed_only flag set correctly. This isn't generally the case, so
keeping dm->deformedOnly = 1 is better.
This flag is copied when converting between DM and Mesh.
This flag is set to true in get_mesh(), to mimick the behaviour of

The outliner can redraw quicker without rebuilding the tree, for example when
just moving the mouse and highlighting different items. The way this worked is
that the outliner would be tagged to avoid rebuilding, however if another
operation that does require rebuilding happens in the meantime we could go out
of sync and crash.
Currently all are stacked together, but perhaps if we don't get any other
tools in the meantime, it would make sense to have them separate.
Notes:
* No icons for now...
* There are some 2.8 bugs with the underlying operators (notably multi object)

check how this is all working. Icons are missing currently, but it's a

Previously, the "layers_used" value was getting updated by the drawing code.
However, when using copy on write, the drawing code gets evaluated copies of
the armature data instead of the original data, so any updates here fail to
get flushed to the original data, hence the lack of updates in the UI.
Fixed by moving the calculation to RNA when setting bone layers, as it should

SSR does not work with hair strands. Basically, the rays are too much
random to ever converge properly and just result in a soup of self
inter reflections.
So forcing it to not produce any SSR. Could potentially save some bandwidth
by not rendering hair to the SSR buffers.
This is a hack to properly shade wire hairs. Use stochastic sampling and
let TAA solve the noise.
At least it's way more correct than the previous hack.
Linking/appending in edit mode currently isn't supported. For workspaces it
should probably be, but we can look into supporting this later.
For now gray out buttons in "Add Workspace" menu while in edit mode.
This avoids having to store the tool definition in the operator
properties (on redraw).
Now just set the name, note this means we can't show the keymap in the
tool-tip anymore. This will eventually be shown in the status bar.
This means only one texture to draw to and only one sprite per pixel.
The texture is twice as large and near and far planes are side by side.
The sprite choose the biggest coc to expand to and is redirected to the
area (layer) it belongs to.
The fragment shader discard every pixel that does not belong to the correct
layer.
Due to the scatter operation being done at half resolution, undersampling
is visible at bokeh shape edges (because of the hard cut).
This commit adds a smoothing function to minimize the problem.
Also optimize the bokeh shape parametrization by precomputing a lot of
constants.
This new blending allows background to fill the gaps left by forground
objects. However this has a drawback, background objects that should be
partially occluded in this case can be seen through the blurred objects.
This does not fix the problem of blurred foreground over sharp background.
Also cleanup code to be simpler and remove unused geometry shader.
The Studio lights are now loaded from disk. The location is
`datafiles/studiolights` they need to be JPG for now. JPG cannot store
HDRI color range but they are clamped inside the Workbench
engine for speed reason. I didn't select JP2K as it might not be
enabled.
Users can add upto 20 HDRI files. This limitation is inside the
RNA_space.c Currently the icons are calculated when you first open the
selection box for the HDRI's. We could add them to a background
rendering later.
I added 2 test files a sky texture rendered in Cycles and an HDRI from
cloud.blender.org.
We can not rely on edit->psys, it is not set for particle edit,
and there is some logic deeper inside which does different things

We need to replace those checks with some some HAIR vs. PARTICLES
flag and always set psys pointer.
The idea is that edit mode structure is owned by original object,
and used for drawing. This is a bit confusing, especially since
path cache is also in that structure and needs evaluated object
to calculate cache.
In the future we should split edit data from visualization data,
but that's bigger refactor.

Also, moved RNA sequencer API functions to proper rna_scene_api.c file.
Two things to indicate (which als apply before the DM → M port):
- Face count in the UI is not updated and stays at 0
- When planar mode is used, the result is inverted (mirrored along X)

Bone selection overlay is only available in pose mode.
and when active overrules the selection buffer.
This is currently `tricked` by switching the draw engines, but this is
an exception. Not sure how to solve this in a better way.
After this is solved we can look at how to localize the dim effect to only the objects connected to the active armatures. Currently it dims the whole screen (including background).

Initial add-cube tool which uses the scale cage to resize.
The 3D cursor is currently used to project the cursor onto.
We'll likely have more orientation options in the future.
NOTE: This is all still heavily WIP, and still requires some additional
layout engine magic to make it all nice.
* Moved current frame, and start/end frame buttons to the end
* Put playback controls in the center
* Remove other more obscure buttons (e.g. Frame menu, lock frame to frame range)
More to follow in next commit...
Now all Keying Set and Auto Keyframing settings can be found the in NKEY
Properties Region (right-hand-side hidden tab/drawer).
This way, we have more room to display the full names of the settings,
without clogging up the timeline header.
Bvhtrees take up a lot of memory space, reusing the common bvhtree of looptris to snap to vertices and edges is a good way to save memory.
Unfortunately we have a worsening performance in the snapping operation around 63% (addition to the original time).
But as we often do not need to build a bvhtree of loose verts and loose edges, we have an improvement in cache time :)
Since the CPU time of snapping operations (no matter how higth poly the object is) corresponds to less than 0.01% of all CPU time of a blender frame, that change is not really significant.
Snapping operations on a mesh in edit mode have not changed significantly.

Everything seems to be working without this, which makes since there is no
evaluation-time edit code in master. The only tricky part here would be that
this means we might want to ensure edit structure exists from inside particle
mode in draw manager.
Other point for not having this code in evaluation is that it's possible to
have same object evaluated in different contexts at the same time, and since
edit structures are supposed to be in original object we might run into
threading conflict.
Readcode always set relative paths of indirectly linked libs relative to
*current* .blend file, not to the library using it.
But BKE_library_filepath_set was then setting them relative to their
parent library, breaking checking code (and saved files even :((( ).
in Scene DNA is available in scene.display New DNA Struct DisplayData
Added RNA (scene.display).
We already have scene.display_settings which contains non viewpoert
specific color management settings. I did not merge those two.
Patch should be in line with the ideas that @brecht wrote in T55008.
As I am not in detail aware of the decisions that have been made for the override feature I want a short review if it is in line with the plans.

This feature is limited (only byte PPM output, no multi-view),
only works with specific configurations.
This also causes some maintenance overhead
when testing changes to the render pipeline.
There is still an issue with the modified mesh not being updated until you
disable and re-enable the modifier. However, after that it'll now also work
while editing the deformation mesh.
The modifier performed the 'bind' operation not in the bind operator,
but delayed in the mesh evaluation. This saved the result in a CoW copy
instead of in the actual modifier data. The binding operator now follows
the same approach as Mesh Deform: it forces the modifiers to run on the
real (non-CoW) data, making it possible for the modifier to store the
binding data.
This commit also ports the usage of DerivedMesh to Mesh.
Patch description:
- Reports "Nothing selected" only when all objects has no selection
and it is in Separate type(Mode)
- Tested all types (Seperate/By Material/By loose parts)
- Instead of using
```
BKE_view_layer_array_from_objects_in_edit_mode_unique_data
```
I used
```
BKE_view_layer_array_from_bases_in_edit_mode_unique_data
```
Because it needs the "Base" not the "Object" itself.

Gets edit more from the current object and displays it as a path.
this is how both hair and particle edit modes are supposed to work.
This only covers path itself, it doesn't do anything like keys
visualization or selection. However, it's already possible to
comb and such.
Only implements particle mode. There are also some settings to
do soft body and cloth. No idea yet what that all is about.
Copy-on-write is not supported either, this is due to some
edit mode ownership problems which are to be addressed from
dependency graph side.
Shading is dead-simple: uses tangent as a color. This is where
i hope to get some help from Clément.
BLI_bvhkdop functions were not made to work with zero-leaf trees.
Perhaps a better solution would be to modify BLI_bvhkdop to work with zero leaf trees.
But this solution of returning NULL was already used for bvhtrees of looptris.
Some years-old deprecated stuff has now been removed.
Correct solution is probably to use valid defines etc. in own code, but
this is more FFMEPG maintainer task (since it also may change how old
FFMPEG we do support...).
When entering edit mode the texture coordinates is not calculated by
drawcachemesh. For now fallback to solid mode. This gives wrong
artifacts when disabling overlays when in edit mode. We should make it
possible to calculate the UVLOOP from bmesh. This will be done in a next
patch
The actual code is a bit convoluted but allows good and "pseudo efficient"
drawing. (pseudo efficient because rendering instances with that amount of
vertices is really inneficient. We should go full procedural but need to
have bufferTexture implemented first) But drawing speed is not a bottleneck
here and it's already a million time less crappy than the old (2.79) immediate
mode method.
Instead of drawing actual wires with different width we render a triangle
fan batch (containing 3 fans: bone, head, tail) which is then oriented in
screen space to the bone direction. We then interpolate a float value
accross vertices giving us a nice blend factor to blend the colors and
gives us really smooth interpolation inside the bone.
The outside edge still being geometry will be antialiased by MSAA if enabled.
Now we use vcos when provided, and fall back to mesh vertices' co
otherwise.
Deform modifiers usually do not have up-to-date coordinates in Mesh
itself, only in given vcos array!
Aside from identation, seed should change for each object. Otherwise to objects
with a copied mesh would get the exactly same "random" selection.
And we do so in a consistent way so it doesn't vary depending on
object order.

This modifier still has issues that are not related to this port:
- While editing the deformation mesh, the deformed mesh doesn't update.
This update only happens after exiting edit mode, making editing
cumbersome.
- Binding doesn't work yet. It works fine when binding in master and
loading pre-bound in 2.8. This was also an issue before this port, and
will be investigated separately.
This function creates a Mesh struct with a number of vertices/edges/etc.
It allocates the minimal number of CD layers needed.
Currently not yet used, but will be soon in the upcoming
BKE_new_mesh_from_curve_displist().
With changes by me:
* Indentation (tabs)
* Removing RNA_boolean_get tests out of the for loop.
* Continue iterator if no selected vertice.

Some notes here:
* Proximity with non-mesh objects (like curve, see TEST_2 scene in
weightvg testfile) are not working currently. This is known TODO of COW
depsgraph project.
* Proximity modifier is slower, due to some other TODO pending on
BVHTree creation/caching for Mesh.
This commit brings back motion path calculations working on same level
as 2.7x. Caveats:
* You cannot actually see anything, as all the drawing code for motion
paths was removed and not reimplmented in 2.8 draw engines yet
* This doesn't actually use a separate depsgraph instance for fast
background calculations yet. That's a separate topic, and will require
further investigation (probably after code quest, according to original
planning).
* The work here *does* however pave the path forwards towards fully separate
COW evaluation though. We only need to stub in a different depsgraph instance
here to get things working.

Note that custom normals drawing seems to be broken, and there also are
some refresh issues in some cases... But this is same with old DM-based
code, so not related to modifiers themselves probably.
Steps to recreate were:
* Go into fullscreen mode (Alt+F10)
* Open debug menu (Ctrl+Alt+D)
* Set value to 1
* Confirming should crash (at least in debug builds)
Was hidden behind debug values 1, 2 and 3.
Also cleaned up logic in region_azone_edge_initialize. It was using a variable
called is_hidden that actually should've been called is_visible.
Since modifier stack is still primarily based on DM in blender2.8, we
need to copy over 'dirty normals' flag from temp Mesh to DM after
modifier has been evaluated.
Scroll-bars are now hidden unless the cursor approaches them, in which case they
smoothly grow and become more & more visible. Note that since 0d309144020168e55,
scroll-bars are drawn on top of editor contents. There's no more jumping of
buttons when scroll-bars appear.
Technical notes:
* AZones are used to adjust scrollbars based on mouse movements
We may want to support screen level AZones if we want scrollbars to also
smoothly appear when approaching them from a different area.
I also plan to make further changes to AZones to clean up stuff a bit.
* Had to move AZone handling to a post ARegion init stage, since we need the
updated View2D data from there.
* View2D masks and scroller rectangles are now updated on every redraw. It's
cheap to do that though.
Scroll-bars used to draw in a little extra space in the editor, causing
buttons to jump a bit when they appeared/disappeared. Now they draw on
top of the buttons, just small enough to avoid bigger overlaps. Followup commits
will do further adjustments.
With this we can get rid of a hack that was calling the (often Python
defined) panel definition - the panel 'draw' callback - twice.
Note: This rely on the property having a pre-defined default.
Also, be aware that trying to multi-drag and multi-ui-edit is not working
at the moment (T54976).

* Ensure popover does not change direction or location.
* Open popover towards the relevant editor, like pulldown menus.
* Use a bigger maximum assumed size to deal with some corner cases.
* Do proper 3D viewport header refresh on shading mode changes.
In object mode, the axes are drawn like any other wire objects with
depth test and depth write. Thus enabling MSAA to work but not their xray
behaviour.
In edit armature/pose mode, draw smooth line without depth testing. This
produces wrong draw ordering problem but still gives the desired xray
behaviour. We do it outside of the MSAA pass since the xray behaviour is not
compatible with it. But we are drawing smoothed lines so no need for MSAA.
The lines are 2px thick and improve readability.
Now the axes are displayed correctly at the tip of the bone and with the
axes names.
I've made some modifications though:
- Axes are colored. (should not be in object mode but that's TODO)
- Axes ends are not flat arrows anymore. Replaced with a small diamond.
- Axes names are now scale by their respective axes instead of being
affected by other axes.
- Changed axes names "font" to be a bit more sexy.
This is for the 3D viewport and image editor. A remaining issue is
that pulldown menu buttons only show text, which is not visible on
all background colors, so making the header entirely transparent
does not work well at the moment.
There is no object to update anyways, and there is no valid basact when the
nified_findnearest() test fails.
How to reproduce the bug: Try to select linked (L) with selected faces but
withotu mouse hovering any mesh.
Bug introduced on: rBbfc9d426bb95 (original multi-object edit commit).
This makes a few changes:
- Remove the old "overlay" wires.
- Add constraints colors to bones.
- Specify a a new "hint" color per bone. Making selection/Active state
more obvious.
- Unify Octahedral/B-Bones/Envelope shading and colors.
- Change outline size depending on the selection/active state of the bone.
Note that thoses changes are not final and needs review.
This will enable us to do more nice stuff in future commits.
This commit is a temporary commit, it will compile but will crash if
trying to display any armature. Next commit does work.
For some we may add per object overrides, but for most we plan to keep them
strictly per viewport settings. Display settings from the mesh still need to
be moved here, only collections were done to remove that code.
While testing UI_OT_reset_default_button, discovered that using
Reset to Default Values on bone locations didn't work. Turns out
to be missing update on this property. So, this is probably
dependent on the property used.
This was the otherway around before. But since we can have a different size*
for cube texture now, we can compute the correct-ish texture size.
This will give us on average the same texture appearance when we will add
support for real cubemap shadows.
As much as I want to give freedom to the user, 1.5G of vram for a
single shadow is a big of a stability issue.
So limiting to 4096 for now, we may remove this limit in the future.
This mean we can now have different shadow resolutions for both.
However each shadow type keep the same size accross all lamps because of
future "real" Cube Shadowmaps limitation and to save texture sampler slots.
That said the cascade shadow resolution could (in the future) still be
changed to be adjustable per sun lamp.
Existing code checked pose/edit mode to check for transforming in an
objects local space.
This added many similar checks all over the code,
which leads to confusion.
Multi-edit caused a regression in UV transform since where UV's
had the object matrix applied by accident.
Now there is a boolean to use a local matrix,
this allows for any mode to have a 4x4 matrix
applied w/o adding mode specific checks everywhere.
Initial review of the shard shadows in the workbench engine.
Speed optimizations like transform feedback are not implemented yet. I first want this part to be reviewed and merged.
@fclem please check the note in drw_stencil_set it was holding back nequal == 0 as by default DST.stencil_mask was set to 0. questioin is should we remove the whole check or not.

Those should be used in priority when you need to create either a new
datablock in Main, or a new temp one. Lower level BKE_libblock_...
should only be used when you need a very specific, uncommon behavior.
The value of epsilon was never used to create this bvhtree because whenever we activate this constraint, a bvhtree with parameter epsilon 0.0 was created and cached.
Seems to be only related on linked nature of particles.
This is caused by some conflicting optimization done for viewport, which
does not do particles re-calculation if they do not depend on time
(which is crucial for big layout scene grass fields) and particle render
setting switch which was relying on fact that render pipeline will do
particle update via time dependency.
Now we extent an old workaround for invisible objects, which now also
deals with particles in the same way as old dependency graph was dealing
with this: tag object data for update if there is particle system.
There shouldn't be any speed difference between old and new depsgraph,
since tagging was already needed and was happening.
In Blender 2.8 such things should be easier to deal with since the whole
depsgraph is to be evaluated for render engine anyway.
`MREMAP_RAYCAST_APPROXIMATE_BVHEPSILON(ray_radius)` greatly increased the radius making for example that 0.1 becoming 1.5
Now the result is much more predictable.
* Remove the "sync_mode" dropdown from timeline header, and move it into
the Playback menu instead.
* Remove the confusing "Frame Dropping" and "AV Sync" entries from the
Playback menu. These were supposed to be mutually exclusive (or else,
the "sync_mode" menu would break).
* Turn AV Sync on by default
* Commented out the Frame Dropping and Av Sync RNA Properties too.
THere doesn't seem to be any valid reason for these to exist?
Note: This still needs some copy-on-write magic to get the bone pointers
to get remapped properly (e.g. evaluated pose still refers to original
arm->bones, and arm->act_bone isn't getting remapped).
After copying animation data we need to re-map action, otherwise
our original DNA values will go out of symc, causing flickering
when tweaking values on animated node tree.
The idea is to re-use evaluated datablock from within current context.
This relies on the following factors:
- It expects scene to be fully evaluated before preview jobs starts.
- It expects datablocks to be localized.
The workaround removal was wrong, the whole id->adt of a local
copy is to be NULL.
But now instead of modifying original datablock, we tell library
manager to not copy animation data.
This was due to the background being drawn by a batch that had its VAO
generated in the windows "UI" context.
Since we use the DRW ogl context to draw the entire area, we have to
regenerate the VAO for thoses UI batches to be drawn correctly.
Does not yet support applying those operations, only detecting
insertions and generating matching rules was already rather complicated.
Also got rid of ;ost rna_path string allocation in collection diffing
code, could help a bit with speed too.
