The merge down operator was sometimes copying the wrong frame, which altered the animation.
While merging the layers, it is sometimes needed to duplicate a keyframe,
when the lowest layer does not have a keyframe but the highest layer does.
Instead of duplicating the previous keyframe of the lowest layer, the code
was actually duplicating the active frame of the layer which was the current frame in the timeline.
This patch fixes the issue by setting the previous keyframe of the layer as its active frame before duplication.

Mutex locks for manipulating GHOST_System::m_timerManager from
GHOST_SystemWayland relied on WAYLAND being the only user of the
timer-manager.
This isn't the case as timers are fired from

Resolve by using a separate timer-manager for wayland key-repeat timers.
Resolve a thread safety issue reported by valgrind's helgrind checker,
although I wasn't able to redo the error in practice.
NULL check on the key-repeat timer also needs to lock, otherwise it's
possible the timer is set in another thread before the lock is acquired.
Now all key-repeat timer access which may run from a thread
locks the timer mutex before any checks or timer manipulation.
There were two errors with the function used to convert face sets

This implements two optimizations:
* If the duplication count is constant, the offsets array can be

* Otherwise, extracting the counts from the virtual array is parallelized.

This is both a cleanup and a preparation for the Principled v2 changes.
Notable changes:
- Clearcoat weight is now folded into the closure weight, there's no reason
to track this separately.
- There's a general-purpose helper for computing a Closure's albedo, which is
currently used by the denoising albedo and diffuse/gloss/transmission color
passes.
- The d/g/t color passes didn't account for closure albedo before, this means
that e.g. metallic shaders with Principled v2 now have their color texture
included in the glossy color pass. Also fixes T104041 (sheen albedo).
- Instead of precomputing and storing the albedo during shader setup, compute
it when needed. This is technically redundant since we still need to compute
it on shader setup to adjust the sample weight, but the operation is cheap
enough that freeing up the storage seems worth it.
- Future changes (Principled v2) are easier to integrate since the Fresnel
handling isn't all over the place anymore.
- Fresnel handling in the Multiscattering GGX code is still ugly, but since
removing that entirely is the next step, putting effort into cleaning it up
doesn't seem worth it.
- Apart from the d/g/t color passes, no changes to render results are expected.

Own mistake in d204830107.
For some buttons the type is changed after construction, which means the button
has to be reconstructed. For example number buttons can be turned into number
slider buttons this way. New code was unintentionally overriding the button
type after reconstruction with the old type again.
Use the `SharedCache` concept introduced in D16204 to share lazily
calculated evaluated data between original and multiple evaluated
curves data-blocks. Combined with D14139, this should basically remove
most costs associated with copying large curves data-blocks (though
they add slightly higher constant overhead). The caches should
interact well with undo steps, limiting recalculations on undo/redo.
Options for avoiding the new overhead associated with the shared
caches are described in T104327 and can be addressed separately.
Simple situations affected by this change are using any of the following data
on an evaluated curves data-block without first invalidating it:
- Evaluated offsets (size of evaluated curves)
- Evaluated positions
- Evaluated tangents
- Evaluated normals
- Evaluated lengths (spline parameter node)
- Internal Bezier and NURBS caches
In a test with 4m points and 170k curves, using curve normals in a
procedural setup that didn't change positions procedurally gave 5x
faster playback speeds. Avoiding recalculating the offsets on every
update saved about 3 ms for every sculpt update for brushes that don't
change topology.

No user-visible changes expected.
Essentially, this makes it possible to use C++ types like `std::function`
inside `uiBut`. This has plenty of benefits, for example this should help
significantly reducing unsafe `void *` use (since a `std::function` can hold
arbitrary data while preserving types).
----
I wanted to use a non-trivially-constructible C++ type (`std::function`) inside
`uiBut`. But this would mean we can't use `MEM_cnew()` like allocation anymore.
Rather than writing worse code, allow non-trivial construction for `uiBut`.
Member-initializing all members is annoying since there are so many, but rather
safe than sorry. As we use more C++ types (e.g. convert callbacks to use
`std::function`), this should become less since they initialize properly on
default construction.
Also use proper C++ inheritance for `uiBut` subtypes, the old way to allocate
based on size isn't working anymore.

Currently this conversion (which happens when using modifiers in edit
mode, for example) is completely single threaded. It's harder than some
other areas to multithread because BMesh elements don't always know
their indices (and vise versa), and because the dynamic AoS format
used by BMesh makes some typical solutions not helpful.
This patch proposes to split the operation into two steps. The first
updates the indices of BMesh elements and builds tables for easy
iteration later. It also checks if some optional mesh attributes
should be added. The second uses parallel loops over all elements,
copying attribute values and building the Mesh topology.
Both steps process different domains in separate threads (though the
first has to combine faces and loops). Though this isn't proper data
parallelism, it's quite helpful because each domain doesn't affect the
others.
**Timings**
I tested this on a Ryzen 7950x with a 1 million face grid, with no
extra attributes and then with several color attributes and vertex
groups.
| File | Before | After |
| Simple | 101.6 ms | 59.6 ms |
| More Attributes | 149.2 ms | 65.6 ms |
The optimization scales better with more attributes on the BMesh. The
speedup isn't as linear as multithreading other operations, indicating
added overhead. I think this is worth it though, because the user is
usually actively interacting with a mesh in edit mode.

The recursion depth was checked for equality with a maximum depth,
allowing leaves with more primitives if a certain depth was reached.
However, a single leaf must always use the same material (including
set_smooth), so if a leaf contained multiple materials it was split
anyway. This meant that in the next recursion step the depth was
larger than the cutoff value and it would go back to recursing until
the number of primitives was small enough, ignoring the recursion
depth for the rest of the process.
In certain edge cases this could lead to a stack overflow.
Even with the check changed from 'equality' to 'larger or equal'
this could still fail in the pathological case where every primitive
has another material. But that can't be helped, and it wouldn't

to how other falloffs work. It's now un-inverted

Also exposed the normals falloff smooth steps as

When the "Hide Value" option of a group input is enabled, only its name
is displayed in group nodes. Modifiers should have the same behavior.
However, for modifiers, only showing the name does not make sense
when the user can't edit the value. Therefore the value is not shown at all.
The image manager used to handle OSL textures on the GPU by
default loads images after displacement is evaluated. This is a
problem when the displacement shader uses any textures, hence
why the geometry manager already makes the image manager
load any images used in the displacement shader graph early
(`GeometryManager::device_update_displacement_images`).
This only handled Cycles image nodes however, not OSL nodes, so
if any `texture` calls were made in OSL those would be missed and
therefore crash when accessed on the GPU. Unfortunately it is not
simple to determine which textures referenced by OSL are needed
for displacement, so the solution for now is to simply load all of
them early if true displacement is used.
This patch also fixes the result of the displacement shader not
being used properly in OptiX.

The default Blender USD export currently produces files that trigger
errors in the usdchecker that ships with USD 22.11.
The changes are:
- Set the defaultPrim if no defaultPrim is set. This sets it to the
first prim in the hierarchy which matches the behaviour of Pixar's
referencing (where referencing a USD layer without a defaultPrim will
pick the first prim) as well as matches the logic in Pixar's Maya USD
exporter code.
- Applies the MaterialBindingAPI to prims with material binding
attributes. This is a relatively new requirement for USD as it will
help for efficiency with upcoming changes to Hydra.
- Removes the preview scope in the USD shader hierarchy, because it
is no longer valid for shaders to have any non-container ancestors in
their hierarchy up until the enclosing Material prim.

Removing all OSL script nodes from the shader graph would cause that
graph to no longer report it using `KERNEL_FEATURE_SHADER_RAYTRACE`
via `ShaderManager::get_graph_kernel_features`, but the shader object
itself still would have the `has_surface_raytrace` field set.
This caused kernels to be reloaded without shader raytracing support, but
later the `DEVICE_KERNEL_INTEGRATOR_SHADE_SURFACE_RAYTRACE`
kernel would still be invoked since the shader continued to report it
requiring that through the `SD_HAS_RAYTRACE` flag set because of
`has_surface_raytrace`.
Fix that by ensuring `has_surface_raytrace` is reset on every shader update,
so that when all OSL script nodes are deleted it is set to false, and only
stays true when there are still OSL script nodes (or other nodes using it).

BKE blendfile should not be allowed to deal with DNA deprectaed data, so
move recent check in rB138b3815e528 into BLO readfile, in a new
`blo_read_file_checks` util that is being called at the very end of main
readfile code (`blo_read_file_internal` and `library_link_end`).
rB7f564d74f9ed (6 years ago!) forgot to clear the deprecated
`Window->screen` pointer on file read for recent-enough .blend files.
This is required since a valid value is always written in .blend files
for that pointer, to ensure backward compatibility.
The issue was never detected so far because that pointer is explicitely
reset to NULL after filewrite, which includes any memfile undostep
write, and usually existing UI data is re-used instead of loading the
one from the .blend file, so thedden assert in `blo_lib_link_restore`
would never be triggered.
Now moved the assert at the end of `setup_app_data` to ensure it always
get checked.

When the sort weights are a single value, they have no effect,
so sorting the relevant indices for the element will be wasted work.
The sorting is expensive compared to the rest of the node. In my
simple test of the points of curve node, it became 6 times faster
when the weights are a single value.
On some occasions, as in cases where transform operations are triggered
via gizmos, the constrain orientations that can be toggled with
multiple clicks of X, Y or Z were repeated.
There is no use in maintaining repeated orientations.
Image Transform use linear or nearest sampling during editing and exporting.
This gets sampling is fine for images that aren't scaled. When sequencing
however you mostly want use some sort of scaling, that leads to poorer
quality.
This change will use sub-sampling to improve the quality. This is only
enabled when rendering. During editing the subsampling is disabled to
keep the user interface reacting as expected.
Another improvement is that image transform is stopped at the moment
it hadn't sampled at least 4 samples for a scan line. In that case we
expect that there are no further samples that would change to result.
In a future patch this could be replaced by a ray/bounding bo intersection
as that would remove some unneeded loops in both the single sampled and
sub sampled approach.
Add an `object.modifiers.move()` method, similar to the one
for constraints and some other collections. Currently reordering
modifiers requires using operators, which depend on context.
The implementation is straightforward, except for the need to
make the severity of errors reported by the underlying editor
code into a parameter, so that the new Python API function
reports any problems as Python exceptions, and refactoring
the code to allow aborting a blocked move before making any
changes. I also turn the negative index condition from an assert

When constructing run-time paths native slashes are preferred as WIN32

Originally, function `sequencer_generic_invoke_xy_guess_channel`
looked in what channel the last strip of the same type is and the
channel used for new strip placement. This was changed as a workaround
when sound strips were added below movie strips
(58bea005c5).
Now these workarounds aren't necessary, but the function was left
unchanged.
Current logic is for adding movie strip to channel 1 is:
- Sound is added to channel 1
- Video is added to channel 2
- If there is only video, it is added to channel 1
Since movie may, or may not contain sound, it is not possible to align
added strips in a way that was done before, unless timeline is analyzed
more in detail, but this would be quite inefficient.
Also, note, that the code did not work, if strip is added next to
previous one, so it mostly did not work as intended.
This commit changes:
- Fix alignment not working when strip is added right next to previous
strip
- Assume that movie strips have sound strip underneath it, so channel
below last movie strip is picked
- For other strip types, pick channel of the last strip of same type
Ultimately, the code is still rather weak, and better system, like using
channel where strip was manually moved, or concept of "typed channels"
would improve this feature.
There is not much documentation on the "snap_point" property, but by
code it is possible to note that it serves to set a target snap point
and is of internal use as it is hidden from the Redo panel.
However, this property was still very dependent on Tools settings and
if set to an operator's call, it changes the scene configurations
inadequately.
Therefore,
- remove this dependency from UI for rotation and resize operators,
- do not change the state of the snap in the scene and
- cleanup the code.
Some transform modes are changeable, so callbacks should be reset
together.
Currently the unchanged `transform_matrix` callback is not a major
issue as it is only used for gizmos and gizmos stop updating when
changing the operator type.

In many cases when reading undo memfile, n the 'restore id from old
main' part of the process, the 'id_old' is not set, which means that
the call to `BKE_main_idmap_insert_id` would try to dereference a `nullptr`.
In practice this is likely not an issue (see comment in code for details),
but at least explicitely check for a nullptr `id_old` pointer.
Would deffer actual cleanup of this area for after 3.5 is branched out.
Currently only affects 'UI' IDs (WindowManager, Screen, etc.), but in
the future other types may be affected as well.
NOTE: this is only used in readfile code itself, not in the

Based on "Sampling the GGX Distribution of Visible Normals" by Eric Heitz
(https://jcgt.org/published/0007/04/01/).
Also, this removes the lambdaI computation from the Beckmann sampling code and
just recomputes it below. We already need to recompute for two other cases
(GGX and clearcoat), so this makes the code more consistent.
In terms of performance, I don't expect a notable impact since the earlier
computation also was non-trivial, and while it probably was slightly more
accurate, I'd argue that being consistent between evaluation and sampling is
more important than absolute numerical accuracy anyways.

It's usually a tiny difference, the only case where I've seen it matter is

Simon mentioned that this gets in the way more than it helps. No geometry
sockets currently show up in the modifier panel. People may build node groups
that have multiple geometry inputs that can be used when the group is used
as node instead of as modifier.
In the future we could also allow e.g. choosing an object to pass into a geometry
socket. That has the problem that we'd also have to duplicate other functionality
of the Object Info node (original vs. relative space).
There were two issues:
* The `new_point_counts_per_curve` was one too large, resulting in
`interpolate_from_neighbors` reading invalid memory.
* Writing the counts into the existing offsets array didn't quite work
because there can be a collision at the offset right between the
last old curve and the first new point. There was a race condition
where this value could be read and written at the same time.
When some path property was displayed in the File Browser, clicking the
icon to open a file browser dialog to choose a file/directory would

allow it when the file browser is opened as a normal editor, not as a
dialog.
Current implementation had some faulty assumtions and had some work
arounds for crashes that were actually limitation of the implementation.
The main reason for this was that the implementation didn't add new
primitives in the same direction it was already adding. Some when
incorrect behavior was detected it was assumed that the part wasn't
manifold (anymore) and didn't fix that part of the mesh.
The new implementation will extract a solution and use this solution
also as the order to generate primitives in uv space.

when fixing seam bleeding. It also adds additional debug tools

Make the functions more flexible and more generic by changing the curves
arguments to the curve offsets. This way, theoretically they could become
normal utility functions in the future. Also do a consistency pass over
the algorithms that generate new curves geometry for naming and
code ordering, and use of utility functions. The functions are really
quite similar, and it's much easier to tell this way.
The most time-consuming operation in merge by distance is to find
duplicate faces (faces that are different but have the same vertices).
Therefore, some strategies were planned to optimize this algorithm:
- Store the corner indices in an array thus avoiding multiple calls of `weld_iter_loop_of_poly_next`;
- Create a map of polygons linked to edges instead of linked to vertices - this decreases the number of connections and reduces the calculation of the intersection of polygon indices.
There are other fields to optimize, like reusing the `wpolys` array
instead of creating a new array of corner offsets. And join some arrays
as members of the same struct to be used in the same buffer.
But for now, it is already a nice optimization. And the new
`poly_find_doubles` function can be reused in the future to create a
generic utility.
The result of the optimization varies greatly depending on the number
of polygons, the size of each polygon and the number of duplicates.
On average it was something around 2 times faster.

These commits moved flags from `eLineArtGPencilModifierFlags` to

from the modifiers `flags` (instead of `calculation_flags`).
This resulted in a false condition (`match_output` was assumed true but

This also fixes the layout of boolean properties with the field toggle

This improves performance in cases where the Set Position node is "turned off"
by passing `false` into the selection input.
It's possible that the node still takes some time in this case currently, because
it is destructing the input fields which may reference geometries that need
to be destructed as well. We could potentially change this node (and others)
so that the field inputs are only requested when the selection is not a

This was not done originally, because one had to iterate over all curves

This adds a new `Interpolate Curves` node. It allows generating new curves
between a set of existing guide curves. This is essential for procedural hair.
Usage:
- One has to provide a set of guide curves and a set of root positions for
the generated curves. New curves are created starting from these root
positions. The N closest guide curves are used for the interpolation.
- An additional up vector can be provided for every guide curve and
root position. This is typically a surface normal or nothing. This allows
generating child curves that are properly oriented based on the
surface orientation.
- Sometimes a point should only be interpolated using a subset of the
guides. This can be achieved using the `Guide Group ID` and
`Point Group ID` inputs. The curve generated at a specific point will
only take the guides with the same id into account. This allows e.g.
for hair parting.
- The `Max Neighbors` input limits how many guide curves are taken
into account for every interpolated curve.

Fixes bug where other islands sometimes get their masks cleared (or
filled) in strange circumstances. Still need to figure out the
correct behavior for spherical falloff.
Mesh islands (shells) are now calculated on an as-needed
basis and cached inside of a temp attribute,
`sculpt_topology_island_key`. This attribute is updated
as needed when geometry changes (e.g. the trim brush)
or when mesh visibility changes.
This replaces the old behavior where the "topology" automasking
mode would walk the entire mesh on every stroke.
The background evaluation samples the sky discretely, so if the sun is
too small, it can be missed in the evaluation. To solve this, the sun is
ignored during the background evaluation and its contribution is
computed separately.
Add an RNA API function that gives an array of the normals for every control point.
The normals depend on the `normal_mode` attribute, which can currently be
minumum twist or Z-up, though more options are planned. Normals are currently
evaluated on the evaluated points and then sampled back to the control points.
Because that can be expensive, a normal mode that only does a first evaluation
on control points may be important
The function is intended to be used by Cycles, so it doesn't have to implement
the calculation of normals itself. They can be interpolated between control points
and normalized.
For best performance, the function should only be called once, since it does the
full calculation for every control point every time it is called.

Based on discussion about T102962, rename the "Face Set Boundaries" node
to "Face Group Boundaries" and the Accumulate Field node's "Group Index"
socket to "Group ID". This convention of "__ Group" and "Group ID" will
be used more in other nodes in the future.
This commit doesn't affect forwards or backwards compatibility.
The reverse iteration added in e091291b5b didn't handle
the case where there are no nodes properly. Thanks to Iliya Katueshenock
for investigating this.
While we do need higher level utilities for copying attributes
between geometries, this currently isn't used and it's not clear
that it will be the right abstraction in the end.
The default when there is no cyclic attribute is that none of the curves
are cyclic. In the mesh to curve node, avoid creating the attribute with
just false to save time and memory usage. Also avoid looking up the
attribute twice in the trim node.
When all the curves are poly curves, skip the work of building a
separate array of offsets for the evaluated points (which are the
same as the control points). This saves 1-4ms on every reevaluation
in test files with many curves.
Standardizing the process of creating a new CurvesGeometry with
different curve sizes based on an existing curves is helpful, since
there are a few methods to simplify the process that aren't obvious
at first, like filling the offsets with sizes directly and accumulating
them to become sizes.
Also, in the trim curves node, avoid creating the curve types attribute
all the time. Use the special API functions for the types which do
some optimizations automatically. Also use a more consistent
method to copy the curve domain data, and correct some comments.
The same logic from D17025 is used in other places in the curve code.
This patch uses the class for the evaluated point offsets and the Bezier
control point offsets. This helps to standardize the behavior and make
it easier to read.
Previously the Bezier control point offsets used a slightly different standard
where the first point was the first offset, just so they could have the same
size as the number of points. However two nodes used a helper function
to use the same `OffsetIndices` system, so switch to that there too.
That requires removing the subtraction by one to find the actual offset.
Also add const when accessing data arrays from curves, for consistency.

This patch adds re-calculation logic (new `BKE_nlastrip_recalculate_blend()` method) to the blend-in/out on transformations to clamp values, and avoid over/under shoot.
The `BKE_nlastrip_recalculate_blend()` encapsulates the existing logic for both the `rna_NlaStrip_blend_in_set()` and `rna_NlaStrip_blend_out_set()` methods into a single BKE method that we an execute as needed. The fact that blend-in is first decreased, is strictly on the order of calculation. My suspicion is that //if// the blend-in / blend-our values were working as intended, the RNA set methods would update in order, and we'd experience the same thing. In short, the choice here was to linearly combine the logic, without making any assumptions of my own.

Caused by {rBeae36be372a6}.
In above commit, `DT_layer_items` shared both `DT_TYPE_MPROPCOL_LOOP` |
`DT_TYPE_MLOOPCOL_LOOP` in a single EnumPropertyItem value "Colors".
This is a bit unusual, but probably allowed.
As a consequence, checks for specific datatypes would fail when selecting
such EnumPropertyItem:
- `DT_DATATYPE_IS_MULTILAYERS` (uses `ELEM` to check distinct entries --
would return false)
- `BKE_object_data_transfer_dttype_to_srcdst_index` (would return
`DT_MULTILAYER_INDEX_INVALID`)
These places have now been corrected to take these "special" values into
account.
Another issue was that multiple EnumPropertyItems with the same value
could be created in dt_add_vcol_layers() if attributes of the same
domain, but different color types are in play (could lead to crashes)
and that has also been corrected.
Also: above commit did not give the choice of transfering color
attributes from the vertex domain (only face corner attributes could be
chosen), this has now been added. DT_layer_vert_items (used from the
modifier) already had this included so this was only an issue when using
the operator outside of the modifiers panel.
Since we now feature two domains, the single "VCOL" in the enum has been
split into "COLOR_VERTEX" and "COLOR_CORNER". This will break existing
scripts calling bpy.ops.object.datalayout_transfer and will be marked as
a breaking change in the release notes.

# Throw deprecation as error and use sys.excepthook to report the user message.
This required a custom exception class to identify the bgl deprecation and a CPython handler function to
be set during python initialization. Although this is the most flexible there was a disconnect between the
exception class, exception function and the excepthook registration.
# A variant how we handle autoexec failures. A flag is stored in Global and when set the user message is reported.

There is a utility method on `CurvesGeometry` to build a map of the
curve for each point. Use that in two more places and make sure its
implementation is multithreaded, which gives a slight speedup
in a simple test file.
When doing partial reloads of asset libraries (only reload assets from
the current file, e.g. after undo re-allocated ID pointers), we'd end up
with assets that don't have their asset data read correctly. It would
execute a branch that didn't set the asset library object necessary to
create and store asset representations.
Steps to reproduce were:
* Open .blend file with geometry node assets in there
* In a geometry node editor, press Shift+A to open the add menu
* Cancel
* Move a node
* Undo
* Press Shift+A again
This allows an engine to perform GPU side view specification and let the
draw manager extract the culling informations (bounds).
To this end, the matrices ubo gets exposed to be able to write to it.
`compute_procedural_bounds()` need to be explicitely called before any
main pass using the culling result.
This abstraction is rarely used. It could be replaced by some more
general "query" API in the future. For now it's easier to just compare
pointers in the Set Position node where this was used.
This is possible now, because mesh positions are stored as flat `float3`
arrays (previously, they were stored as `MVert` with some other data
interleaved).
This changes how we access the points that correspond to each curve in a `CurvesGeometry`.
Previously, `CurvesGeometry::points_for_curve(int curve_index) -> IndexRange`
was called for every curve in many loops. Now one has to call
`CurvesGeometry::points_by_curve() -> OffsetIndices` before the
loop and use the returned value inside the loop.
While this is a little bit more verbose in general, it has some benefits:
* Better standardization of how "offset indices" are used. The new data
structure can be used independent of curves.
* Allows for better data oriented design. Generally, we want to retrieve
all the arrays we need for a loop first and then do the processing.
Accessing the old `CurvesGeometry::points_for_curve(...)` did not follow
that design because it hid the underlying offset array.
* Makes it easier to pass the offsets to a function without having to
pass the entire `CurvesGeometry`.
* Can improve performance in theory due to one less memory access
because `this` does not have to be dereferenced every time.
This likely doesn't have a noticable impact in practice.

As noted in comments, there are a lot of false positives which can't
be conveniently suppressed. Many of these warnings were caused by
`float x, y, z` being passed as `float[3]` using a pointer to `x`.
This makes `GVArrayImpl` and `VArrayImpl` more similar.
Only passing the pointer instead of the span also increases
efficiency a little bit. The downside is that a few asserts had
to be removed as well. However, in practice the same asserts
are in place at a higher level as well (in `VArrayCommon`).
In most cases it is currently not used, so always having it there
causes unnecessary overhead. In my test file that causes
a 2 % performance improvement.
Previously, `ParamsBuilder` lazily allocated an array for an
output when it was unused, but the called multi-function
wanted to access it. Now, whether the multi-function supports
an output to be unused is part of the signature. This way, the
allocation can happen earlier when the parameters are build.
The benefit is that this makes all methods of `MFParams`
thread-safe again, removing the need for a mutex.
`std::get` could not be used due to restrictions on macos.
However, the minimum requirement has been lifted in
{rB597aecc01644f0063fa4545dabadc5f73387e3d3}.
Currently you can retrieve a mutable array from a const CustomData.
That makes code unsafe since the compiler can't check for correctness
itself. Fix that by introducing a separate function to retrieve mutable
arrays from CustomData. The new functions have the `_for_write`
suffix that make the code's intention clearer.
Because it makes retrieving write access an explicit step, this change
also makes proper copy-on-write possible for attributes.
Notes:
- The previous "duplicate referenced layer" functions are redundant
with retrieving layers with write access
- The custom data functions that give a specific index only have
`for_write` to simplify the API

Timecodes were generated from read packets, but applied to decoded

This way delay can be eliminated and timecode files are more reliable.
Effectively this disables two volume modifiers for the new curves
object and the point cloud object types. The aim is to simplify the
process of using these object types to prove out a node-group-based
workflow integrated with the asset browser. We're making the assumption
that these two modifiers were used very rarely on the new curves type
since that wasn't its purpose, so this breaks backwards compatibility.
Similar to the corresponding properties on node sockets, only adjust
the soft range. Because group nodes only have soft limits, groups
should generally be able to accept these inputs anyway. The benefit
of only using a soft range is that it allows choosing a more user-
friendly default range while keeping flexibility.
A proper boolean custom property type is commonly requested. This
commit simply adds a new `IDP_BOOLEAN` type that can be used for
boolean and boolean array custom properties. This can also be used
for exposing boolean node sockets in the geometry nodes modifier.
I've just extended the places existing IDProperty types are used, and
tested with the custom property edit operator and the python console.
Adding another IDProperty type is a straightforward extension of the

Replace the pointers in the MeshEdge with indexes, removing MeshPrimitive and MeshVertex.
Code cleanup proposed by the geometry nodes to make the data structures more reusable by
other areas of Blender as well. Old implementation was to focused to the texture painting.
Initial the idea was to do the same with the data structures in UVIslands, but there some
concerns were raised that requires a different design than expected from a clean-up patch.
Concerns raised about converting UVIslands:
* Maps between UVPrimitive, UVEdge and UVVertex will be stored inside the UVIsland.
During UVIsland extraction detected islands can be merged. When they are merged all
Indexes should be updated.
* It is not possible to pre-allocate all buffers as they grow, what will lead to more re-allocations. The current
implementation uses a VectorList to ensure that re-allocations don't require the data to be
moved to the newly allocated memory. We could store some information about last used
sizes in runtime data to reduce the re-allocation overhead.
* Solution would require index based access inside a VectorList, which might increase the
complexity.
* UVIslands during 3d texturing is used as intermediate data, the final data is stored as PackedPixelRows.
We could proceed converting UVIslands as well, but that would lower the performance noticeably.
3D texturing has performance requirements, so when doing so we should make sure that
it matches that as well.

The mesh positions are now a span, but the convex hull didn't copy

Currently the `MLoopUV` struct stores UV coordinates and flags related
to editing UV maps in the UV editor. This patch changes the coordinates
to use the generic 2D vector type, and moves the flags into three
separate boolean attributes. This follows the design in T95965, with
the ultimate intention of simplifying code and improving performance.
Importantly, the change allows exporters and renderers to use UVs
"touched" by geometry nodes, which only creates generic attributes.
It also allows geometry nodes to create "proper" UV maps from scratch,
though only with the Store Named Attribute node for now.
The new design considers any 2D vector attribute on the corner domain
to be a UV map. In the future, they might be distinguished from regular
2D vectors with attribute metadata, which may be helpful because they
are often interpolated differently.
Most of the code changes deal with passing around UV BMesh custom data
offsets and tracking the boolean "sublayers". The boolean layers are
use the following prefixes for attribute names: vert selection: `.vs.`,
edge selection: `.es.`, pinning: `.pn.`. Currently these are short to
avoid using up the maximum length of attribute names. To accommodate
for these 4 extra characters, the name length limit is enlarged to 68
bytes, while the maximum user settable name length is still 64 bytes.
Unfortunately Python/RNA API access to the UV flag data becomes slower.
Accessing the boolean layers directly is be better for performance in
general.

Wayland requires the windows surface size is divisible by the surface
scale. This wasn't guaranteed when creating new temporary windows.
This meant opening the preferences could exit Blender with an error
with Hi-DPI configurations.
**Changes**
As described in T93602, this patch removes all use of the `MVert`
struct, replacing it with a generic named attribute with the name
`"position"`, consistent with other geometry types.
Variable names have been changed from `verts` to `positions`, to align
with the attribute name and the more generic design (positions are not
vertices, they are just an attribute stored on the point domain).
This change is made possible by previous commits that moved all other
data out of `MVert` to runtime data or other generic attributes. What
remains is mostly a simple type change. Though, the type still shows up
859 times, so the patch is quite large.
One compromise is that now `CD_MASK_BAREMESH` now contains
`CD_PROP_FLOAT3`. With the general move towards generic attributes
over custom data types, we are removing use of these type masks anyway.
**Benefits**
The most obvious benefit is reduced memory usage and the benefits
that brings in memory-bound situations. `float3` is only 3 bytes, in
comparison to `MVert` which was 4. When there are millions of vertices
this starts to matter more.
The other benefits come from using a more generic type. Instead of
writing algorithms specifically for `MVert`, code can just use arrays
of vectors. This will allow eliminating many temporary arrays or
wrappers used to extract positions.
Many possible improvements aren't implemented in this patch, though
I did switch simplify or remove the process of creating temporary
position arrays in a few places.
The design clarity that "positions are just another attribute" brings
allows removing explicit copying of vertices in some procedural
operations-- they are just processed like most other attributes.
**Performance**
This touches so many areas that it's hard to benchmark exhaustively,
but I observed some areas as examples.
* The mesh line node with 4 million count was 1.5x (8ms to 12ms) faster.
* The Spring splash screen went from ~4.3 to ~4.5 fps.
* The subdivision surface modifier/node was slightly faster
RNA access through Python may be slightly slower, since now we need
a name lookup instead of just a custom data type lookup for each index.
**Future Improvements**
* Remove uses of "vert_coords" functions:
* `BKE_mesh_vert_coords_alloc`
* `BKE_mesh_vert_coords_get`
* `BKE_mesh_vert_coords_apply{_with_mat4}`
* Remove more hidden copying of positions
* General simplification now possible in many areas
* Convert more code to C++ to use `float3` instead of `float[3]`
* Currently `reinterpret_cast` is used for those C-API functions

When rendering in the viewport (or probably on instanced objects, but I didn't
test that), emissive objects whose scale is negative give the wrong value on the
"backfacing" input when multiple sampling is enabled.
The underlying problem was a corner case in how normal transformation is handled,
which is generally a bit messy.
From what I can tell, the pattern appears to be:
- If you first transform vertices to world space and then compute the normal from
them (as triangle light samping, MNEE and light tree do), you need to flip
whenever the transform has negative scale regardless of whether the transform
has been applied
- If you compute the normal in object space and then transform it to world space
(as the regular shader_setup_from_ray path does), you only need to flip if the
transform was already applied and was negative
- If you get the normal from a local intersection result (as bevel and SSS do),
you only need to flip if the transform was already applied and was negative
- If you get the normal from vertex normals, you don't need to do anything since
the host-side code does the flip for you (arguably it'd be more consistent to
do this in the kernel as well, but meh, not worth the potential slowdown)
So, this patch fixes the logic in the triangle emission code.
Also, turns out that the MNEE code had the same problem and was also having
problems in the viewport on negative-scale objects, this is also fixed now.

Incorrect offset was calculated when strip was implicitly retimed (movie
FPS does not match scene FPS). This is because strip playback rate was
not used for offset calculation at all.
Since hold offset is specifying numbers of frames to skip, but at frame
rate of the source, this could result in gap when splitting the strip.
If that occurs, gap is compensated by moving handle to frame where strip
is split.
Happens, for example, when the object has animation, and disabled for
render, and animation render is performed.
The regression has been uncovered by f12f7800c2 which made it so
the dependency graph relies on runtime visibility tracking and
updates (without updating relations).
The optimization from a while ago in the ff60dd8b18 got in a way
of the visibilit updates because it removed relation between two
no-op nodes which belong to different IDs, which make the visibility
tracking impossible.
This change makes it so only relations which belong to the same
component are removed. This matches the expectations of the visibility
tracking (which, actually, also needed to happen at the moment of the
initial optimization commit). Technically, this change could introduce
some performance regression, but with the current design design of the
graph it is not really avoidable.
The idea to gain the best performance is to separate relations which
actually define the execution flow, and which are only needed to
define things like visibility dependencies.
When drawing using the option `Outline` the result stroke

The code that computes and inverts the shutter CDF had some issues that caused
the result to be asymmetric, this tweaks it to be more robust and produce
symmetric outputs for symmetric inputs.
At the first bounce, the diffuse/glossy/transmission weights are stored so that
contributions along the path can be split into the d/g/t indirect passes.
However, volume bounces always set the weight even at indirect bounces, so
even paths that had their first bounce on a purely glossy object would suddenly
start counting towards the diffuse indirect pass after a secondary volume bounce.

During geometry nodes evaluation some sockets can be determined
to be unused, for example based on the condition input in a switch node.
Once a socket is determined to be unused, that information has to be
propagated backwards through the tree to free any memory that may
have been reserved for those sockets already. This is happening before
this commit already, but in a less ideal way.
Determining that sockets are unused early is good because it helps with
memory reuse and avoids copy-on-write copies caused by shared data.
Now, nodes that are scheduled because an output became unused have
priority over nodes scheduled for other reasons.
This allows auto-vectorization to happen when the a multi-function is
evaluated in "materialized" mode, i.e. it is processed in chunks where
all input and outputs values are stored in contiguous arrays.
It also unifies the handling input, mutable and output parameters a bit.
Now they all can use tempory buffers in the same way.
Staging texture update copied over the entire texture, rather than just the region of the texture which had been updated. Also added early-exit for cases where the net texture update extent was zero, as this was causing validation failures.

This was caused by rB0d73d5c1a2, which releases the scene mutex during kernel
loading. However, the reset mutex was still held, which can cause a deadlock
if another thread tries to reset the session, since it will acquire the
released scene mutex and then wait for the reset mutex.
Turns out there's no point in keeping the reset mutex locked after the delayed
reset section, so now we just release it earlier, which resolves the deadlock.
This mainly helps GCC catch up with Clang in terms of field evaluation
performance in some cases. In some cases this patch can speedup
field evaluation 2-3x (e.g. when there are many float math nodes).
See D16942 for a more detailed benchmark.
This moves all multi-function related code in the `functions` module
into a new `multi_function` namespace. This is similar to how there
is a `lazy_function` namespace.
The main benefit of this is that many types names that were prefixed
with `MF` (for "multi function") can be simplified.
There is also a common shorthand for the `multi_function` namespace: `mf`.
This is also similar to lazy-functions where the shortened namespace
is called `lf`.
* `depends_on_context` was not used for a long time already.
* `param_data_indices` is not used since rB42b88c008861b6.
* The remaining data is moved to a single `Vector` to avoid
having to do two allocations when the size signature becomes
larger than fits into the inline buffer.
This avoids a move of the signature after building it. Tthe value had
to be moved out of `MFSignatureBuilder` in the `build` method.
This also makes the naming a bit less confusing where sometimes
both the `MFSignature` and `MFSignatureBuilder` were referred
to as "signature".
* New `build_mf` namespace for the multi-function builders.
* The type name of the created multi-functions is now "private",
i.e. the caller has to use `auto`. This has the benefit that the
implementation can change more freely without affecting
the caller.
* `CustomMF` does not use `std::function` internally anymore.
This reduces some overhead during code generation and at
run-time.
* `CustomMF` now supports single-mutable parameters.
This refactors how devirtualization is done in general and how
multi-functions use it.
* The old `Devirtualizer` class has been removed in favor of a simpler
solution. It is also more general in the sense that it is not coupled
with `IndexMask` and `VArray`. Instead there is a function that has
inputs which control how different types are devirtualized. The
new implementation is currently less general with regard to the number
of parameters it supports. This can be changed in the future, but
does not seem necessary now and would make the code less obvious.
* Devirtualizers for different types are now defined in their respective
headers.
* The multi-function builder works with the `GVArray` stored in `MFParams`
directly now, instead of first converting it to a `VArray<T>`. This reduces
some constant overhead, which makes the multi-function slightly
faster. This is only noticable when very few elements are processed though.
No functional changes or performance regressions are expected.
This implement most of the functions provided by the BLI math library.
This is part of the effort to unify GLSL and C++ syntax. Ref T103026.
This also adds some infrastructure to make it possible to run GLSL shader unit

Some code already present in other libs is being copied to the new libs.
This patch does not make use of the new libs outside of the tests.
Note that the test is still crashing when using metal.
This was limiting the use of the templates with other non internal types
like Ceres types, xithout defining thing like that:
`template<> inline constexpr bool is_math_float_type<mpq_class> = true;`
This breaks backwards compatibility some in that 3 sides will be mapped
differently now, but difficult to avoid and can be considered a bugfix.

This patch implements the matrix types (i.e:float4x4) by making heavy
usage of templating. All matrix functions are now outside of the vector
classes (inside the blender::math namespace) and are not vector size
dependent for the most part.
###Motivations
The goal/motivations of this rewrite are the same as the Vector C++ API (D13791):
- Template everything for making it work with any types and avoid code duplication.
- Use functional style instead of Object Oriented function call to allow a simple compatibility layer with GLSL syntax (see T103026 for more details).
- Allow most convenient constructor syntax and accessors (array subscript `matrix[c][r]`, or component alias `matrix.y.z`).
- Make it cover all features the current C API supports for adoption.
- Keep compilation time and debug performance somehow acceptable.
###Consideration:
- The new `MatView` class can be generated by `my_float.view<NumCol, NumRow, StartCol, StartRow>()` (with the last 2 being optionnal). This one allows modifying parts of the source matrix in place. It isn't pretty and duplicates a lot of code, but it is needed mainly to replace `normalize_m4`. At least I think it is a good starting point that can refined further.
- An exhaustive list of missing `BLI_math_matrix.h` functions from the new API can be found here P3373.
- This adds new Rotation types in order to have a clean API. This will be extended when we port the full Rotation API. The types are made so that they don't allow implicit down-casting to their vector representation.
- Some functions make direct use of the Eigen library, bypassing the Eigen C API defined in `intern/eigen`. Its use is contained inside `math_matrix.cc`. There is conflicting opinion wether we should use it more so I contained its usage to almost the tasks as in the C API for now.

This patch allows the realtime compositor to be limited to a specific
compositing region that is a subset of the full render region. In the
context of the viewport compositor, when the viewport is in camera view
and has a completely opaque passepartout, the compositing region will be
limited to the visible camera region.
On the user-level, this gives the user the ability to make the result of
the compositor invariant of the aspect ratio, shift, and zoom of the
viewport, making the result in the viewport identical to the final
render compositor assuming size relative operations.
It should be noted that compositing region is the *visible* camera
region, that is, the result of the intersection of the camera region and
the render region. So the user should be careful not to shift or zoom
the view such that the camera border extends outside of the viewport to
have the aforementioned benefits. While we could implement logic to fill
the areas outside of the render region with zeros in some cases, there
are many other ambiguous cases where such a solution wouldn't work,
including the problematic case where the user zooms in very close,
making the camera region much bigger than that of the render region.

Using negative blend factors for blending in flipped poses was undesirable.
Instead, the pose blending operator now uses CTRL to flip the pose.
Negative blend values are still allowed, and cause the pose asset to be
subtracted from the current pose. It can quickly break the rig, but for
small adjustments it can be useful.
The slider component can now be told to not use CTRL for toggling stepped
10% increments. This is useful when the operator that uses the slider needs
that modifier key for its own purposes.

Delete empty index files if the modification timestamp indicates a time

possible time zone differences). This will basically make Blender skip
the optimization for .blend files without assets for one load, but even
then the index should still produce faster results than a completely

so sort the triangle index pair to restore behavior exactly identical

Follow up to rB0796210c8df32
Previously cloth self-collision and other code that wants self-overlap
data was using an ordinary BVH overlap utility function. This works,
but is suboptimal because it fails to take advantage of the fact that
it is comparing two identical trees.
The standard traversal for self-collision essentially devolves into
enumerating all elements of the tree, and then matching them to the
tree starting at the root. However, the tree itself naturally partitions
the space, so overlapping elements are likely to be mostly placed nearby
in the tree structure as well.
Instead, self-overlap can be computed by recursively computing ordinary
overlap between siblings within each subtree. This only considers each
pair of leaves once, and provides significantly better locality.
It also avoids outputting every overlap pair twice in different order.

select all fcurve`s keyframes anymore and this wasnt actually an issue
with that particular operator, but instead with another operator that is

keyconflict here is actually wanted behavior).
Channel renaming would not return `OPERATOR_PASS_THROUGH` here anymore
in the case nothing cannot be renamed, so we would not actually reach
the 2nd operator at all (the one selecting all keyframes).
Deeper reason for this is that the renaming operator would actually
"see" a channel that could be renamed (in the case of the report: an
annotation layer), but then cannot proceed, because the "real"
underlying data where the doubleclick happens is an fcurve...
So now exclude non-greasepencil channels in filtering as well where
appropriate by also adding `ANIMFILTER_FCURVESONLY` to the filter there.

and peak memory usage. Even the lockfree allocator used to use a
global atomic variable for the memory usage. When multiple threads
use the allocator at the same time, this variable is highly contended.
This can result in significant slowdowns as presented in D16862.
While specific cases could always be optimized by reducing the number
of allocations, having this synchronization point in functions used by
almost every part of Blender is not great.
The solution is use thread-local memory counters which are only added
together when the memory usage is actually requested. For more details
see in-code comments and D16862.

There are dependencies between shared libraries, and Python modules which are
always installed on Linux and macOS can use these also.
Instead of adding logic for dealing with dependencies and conditional Python
module installs, just always install everything when using precompiled
libraries. This does not affect compile time which would be the main reason to
turn off build options, and it does not affect the case where system libraries
are used.
More automatic and convenient to update existing configurations this way.
Also move into platform_old_libs_update.cmake where similar logic was put
already.
WLROOTS compositors don't run surface leave callbacks,

Use the same `".selection"` attribute for both curve and point domains,
instead of a different name for each. The attribute can now have
either boolean or float type. Some tools create boolean selections.
Other tools create float selections. Some tools "upgrade" the attribute
from boolean to float.
Edit mode tools that create selections from scratch can create boolean
selections, but edit mode should generally be able to handle both
selection types. Sculpt mode should be able to read boolean selections,
but can also and write float values between zero and one.
Theoretically we could just always use floats to store selections,
but the type-agnosticism doesn't cost too much complexity given the
existing APIs for dealing with it, and being able to use booleans is
clearer in edit mode, and may allow future optimizations like more
efficient ways to store boolean attributes.
The attribute API is usually used directly for accessing the selection
attribute. We rely on implicit type conversion and domain interpolation
to simplify the rest of the code.

Avoid saving the 'flipped' operator property of the "apply pose asset"
(`POSELIB_OT_apply_pose_asset`) operator. This caused problems: when
choosing "Apply Pose Flipped" in the asset browser, double-clicking a pose
would cause it to always be flipped.
Interactive blending of poses can now use negative factors (i.e. drag to
the left) to blend in the flipped pose.
This reverts rB6eb1c98b15bb7ea6cf184b08617f24c7afb91b6c where the F key
was used to flip the pose. That was already described as stop-gap
measure, and the new behaviour is more intuitive & direct.
Functionality over-the-shoulder reviewed by @hjalti.
Add a field `is_bidirectional` to sliders (`tSlider`). By defafult this
is `false`; when set to `true` the slider allows negative values.
The allowed ranges are now:
- No overshoot, no bidirectional: `[0, 1]`
- No overshoot, bidirectional: `[-1, 1]`
- Overshoot, no bidirectional: `[0, infinity)`
- Overshoot, bidirectional: `(-infinity, infinity)`
This will be used for the pose library blending operator, where sliding
to the right (postitive) blends as normal, and sliding to the left
(negative) flips the pose before blending.
This is part of D16858. Iterating over all field inputs allows us to extract
all anonymous attributes used by a field relatively easily which is necessary
for D16858.
This could potentially be used for better field tooltips for nested fields,
but that needs further investigation.
This is part of D16858 but is also useful for other purposes.
The changes to the node declaration in this commit allow us to figure
out which fields might be evaluated on which geometries statically (without
executing the node tree). This allows for deterministic anonymous attribute
handling, which will be committed separately. Furthermore, this is necessary
for usability features that help the user to avoid creating links that don't
make sense (e.g. because a field can't be evaluated on a certain geometry).
This also allows us to better separate fields which depend or don't depend
on anonymous attributes.
The main idea is that each node defines some relations between its sockets.
There are four relations:
* Propagate relation: Indicates that attributes on a geometry input can be
propagated to a geometry output.
* Reference relation: Indicates that an output field references an inputs field.
So if the input field depends on an anonymous attribute, the output field
does as well.
* Eval relation: Indicates that an input field is evaluated on an input geometry.
* Available relation: Indicates that an output field has anonymous attributes
that are available on an output geometry.
These relations can also be computed for node groups automatically, but that
is not part of this commit.
This was the case when done via the py-API.
Now also set active_color_attribute / default_color_attribute on newly
created attributes (in case none exist yet).

Python API for moving strips to and from meta strips did not invalidate
strip lookup cache. Because of that, `SEQ_get_seqbase_by_seq()` failed
to lookup origin of strip, which resulted in crash on NULL dereference.
Invalidateion was added to functions `SEQ_edit_move_strip_to_meta()` and
`SEQ_add_meta_strip()`.
Partly a cleanup, but also iterating over spans can be faster than
linked lists. Also rewrite the multi-input socket link counting
to avoid the need for a temporary map. Overall, on my setup the changes
save about 5% (3ms) when drawing a large node tree (the mouse house file).
Small memory allocations are a bottleneck when drawing large node trees.
Avoid them by passing the socket index in the whole tree and getting the
tree from the context rather than allocating structs for the tree, node,
and socket. The performance improvement will be a few percent at most.
This was an oversight in rBdba2d828462ae22de5.
The evaluator uses multiple threads to initialize node states
but it is still in single threaded mode.
`get_main_or_local_allocator` did not return the right allocator
in this case.
During pose blending, when flipping the pose with {key F}, the pose
backup needs to be recreated. Without this, the blending wouldn't be
done properly.
F-for-flipping was introduced in rB6eb1c98b15bb7ea6cf184b08617f24
While blending poses from the pose library, press {key F} to flip the
pose.
Since rBc164c5d86655 removed the "Flip Pose" checkbox, there was no more
way to blend poses flipped.
Note that this is a bit of a stop-gap measure. The goal is to have a
bidirectional blend slider, where dragging to the left flips the pose,
and dragging to the right blends it normally.
As an optimization, dependency graph evaluation skips through
no-op nodes at the scheduling stage. However, that leaves update
flags enabled on the node, and the most problematic one is the
USER_MODIFIED flag, which get flushed to children every time
the no-op node is tagged.
This in turn can cause simulation caches downstream to be
permanently stuck in an outdated state until the depsgraph
is rebuilt and the stuck flag cleared out.

Expose `BKE_pose_apply_action_blend` and a simplified pose backup system
to RNA. This will make it possible to easily create some interactive
tools in Python for pose blending.
When creating a backup via this API, it is stored on the
`Object::runtime` struct. Any backup that was there before is freed
first. This way the Python code doesn't need access to the actual
`PoseBackup *`, simplifying memory management.
The limitation of having only a single backup shouldn't be too
problematic, as it is meant for things like interactive manipulation of
the current pose. Typical use looks like:
- Interactive operator starts, and creates a backup of the current pose.
- While the operator is running:
- The pose backup is restored, so that the next steps always use the
same reference pose.
- Depending on user input, determine a blend factor.
- Blend some pose from the pose library into the current pose.
- On confirmation, leave the pose as-is.
- On cancellation, restore the backup.
- Free the backup.
`BKE_pose_apply_action_blend` is exposed to RNA to make the above
possible.
An alternative approach would be to rely on the operator redo system.
However, since for poses this would use the global undo, it can get
prohibitively slow. This change is to make it easier to prototype
things; further into the future the undo system for poses should be
improved, but that's an entire project on its own.

While the cost of creating AttributeAccessor and finding the "material_index"

Move `pose_backup.cc` from `editors/armature` to `blenkernel`. This is
in preparation of an upcoming change where the pose backup is going to be
owned by the `Object`. This will need to be automatically cleared when the
object is freed, which means that `blenkernel` needs the corresponding
logic.
Technically only the freeing code could be moved, but I felt it made more
sense to keep the related code together.
No functional changes.
The "osl_texture" intrinsic was not implemented correctly. It should handle alpha

There are two underlying issues which got uncovered by the report:
First, is that the poll() function for the operator was using legacy
API which is on its way of removal in the next major version release.
This part is fixed in this patch based on a patch provided by Philipp
Oeser (P3389) with the modification that the `clip` is not accessed
prior to None check. Ended up in a bit annoying one-liner, the entire
function could be refactored to use early returns.
The second issue is that the Python access to the legacy property
was wrong: need to access camera reconstruction instead of accessing
deprecated DNA field.
Some files out there (e.g. in T103441) contain face definitions with
four indices, which the importer code was not expecting. The OBJ
standard spells out up to three indices per face corner; the file in
there must be using some sort of non-standard OBJ syntax extension.
Now the code simply ignores any trailing per-face-corner data.
Similar to T98782 that was about normal indices: some files out there
are technically "wrong" since they refer to UV indices, without ever
defining any UVs. If the file does not have any UVs, simply ignore UV
indices in the OBJ face definitions. Fixes T103212.

This 'requirement' does not seem to be necessary since the Dopesheet is already in Grease Pencil mode and there is an active Grease Pencil Object. It is also not apparent as to why so many Operators depend on it and unintuitive that it controls their function. The 'Only Show Selected' filter button is far away from the Operator buttons in the User Interface Header, so it's difficult to make the association.
If the 'Only Show Selected' IS absolutely required, I believe it should be closer to the DOPESHEET_HT_editor_buttons. Otherwise, I think the requirement should be removed.

The geometry nodes evaluator supports "lazy threading", i.e. it starts out
single-threaded. But when it determines that multi-threading can be
benefitial, it switches to multi-threaded mode.
Now it only creates an enumerable-thread-specific if it is actually using
multiple threads. This results in a 6% speedup in my test file with many
node groups and math nodes.
When these declarations are built without the help of the special
builder class, it's much more convenient to set them directly rather
than with a constructor, etc. In most other situations the declarations
should be const anyway, so theoretically this doesn't affect safety too
much. Most construction of declarations should still use the builder.
Whenever a node group is entered during evaluation, a new compute
context is entered which has a corresponding hash. When node groups
are entered and exited a lot, this can have some overhead. In my test
file with ~100.000 node group invocations, this patch improves performance
by about 7%.
The speedup is achieved in two ways:
* Avoid computing the same hash twice by caching it.
* Invoke the hashing algorithm (md5 currently) only once instead of twice.
Geometry nodes used to log all socket values during evaluation.
This allowed the user to hover over any socket (that was evaluated)
to see its last value. The problem is that in large (nested) node trees,
the number of sockets becomes huge, causing a lot of performance
and memory overhead (in extreme cases, more than 70% of the
total execution time).
This patch changes it so, that only socket values are logged that the
user is likely to investigate. The simple heuristic is that socket values
of the currently visible node tree are logged.
The downside is that when the user changes the visible node tree, it
won't have any logged values until it is reevaluated. I updated the
tooltip message for that case to be a bit more precise.
If user feedback suggests that this new behavior is too annoying, we
can always add a UI option to log all socket values again. That shouldn't
be done without an actual need though because it takes up UI space.

Read the selection attribute on the proper domain using implicit
interpolation rather than just using its oiginal domain that might
not match the domain of the color attribute.
Lazy-function graphs are now evaluated properly even if they contain
cycles. Note that cycles are only ok if there is no data dependency cycle.
For example, a node might output something that is fed back into itself.
As long as the output can be computed without the input that it feeds into,
everything is ok.
The code that builds the graph is responsible for making sure that there
are no actual data dependencies.

Re. T99618.
Use socket indices to keep track of logged values instead of their
identifiers. This decreases memory pressure when there are many
sockets. In cases with many cheap nodes, this can give a relatively
large improvement to overall performance. We observed a 15% increase
in a case with many math nodes and a larger increase in an experimental
softbody node setup. The log is invalidated when we add/remove/move
sockets anyway.
This is the best way I found to make building socket declarations without
the builder helper class work. Besides a vague hope for non-leaky
abstractions, I don't think there's any reason for these fields not to be
accessible directly.

This patch makes sure that each of the expand keymap entries will use consistent "invert" and "use_mask_preserve" properties.
Based on previous discussions we decided to flip the default Mask Expand behavior.
This has multiple benefited:
- The mask creation is more consistent with other masking tools (Always add to existing mask. Mask selected areas)
- It's easier to use expanding for masking face sets (Snapping with `Ctrl`) or building a mask from repeated operations
- It's less likely to mask certain areas unintentionally (Loose mesh islands)
- If the current behavior is desired for an expand operation the user can use `E` & `F` in the modal keymap (Which is less often the case).
If we want to revisit the original design of inverted masking again in the future we should do this via {T97903}.

The Realtime Compositor crashes on undo after an operation like Dissolve
node.
The compositor evaluator stored a reference to the compositor node tree
assuming that it will always be valid. This is not guaranteed, however,
and changes to the node tree can invalidate that reference. So we get
the node tree from the context directly every time to fix the crash.
Such IDs are tagged with the new `LIB_TAG_RUNTIME`. They are essentially
like any other regular ID, except that they do not get written in .blend
files. They also do not make their linked data usages directly linked.
They do be written in undo steps however.
This tag should be ignored in any non-Main IDs (e.g. evaluated data,
`NO_MAIN`, etc.).
This commit also adds a new RNA ID property, `is_runtime`. This is not a
direct mapping to the DNA tag, as a non-main ID will also return True,
and the property is only editable for Main IDs.
Some basic testing for expected behavior of that new tag was also added

When creating a new mesh to change it in some way, the active and

Doing that in the generic "copy parameters for eval" function should

Accessing a mesh with write access can be costly if it is used

This patch implements the Streaks Glare node. Which is an approximation
to the existing implementation in the CPU compositor. The difference due
to the approximation is bearily visible in artificial test cases, but is
less visible in actual use cases. Since the difference is rather similar
to that we discussed in the Simple Star mode, the decision to allow that
difference would probably hold here.
For the future, we can look into approximating this further using a
closed form IIR recursive filter with parallel interconnection and
block-based parallelism. That's because the streak filter is already
very similar to the causal pass of a fourth order recursive filter,
just with exponential steps.

This patch implements the variable size mode of the blur node. This is
not identical to the CPU implementation, but is visually very close.
That's because of two things. First, the Extend Bounds option introduces
a 2px offset that doesn't make sense, which is likely a bug in the CPU
implementation. Second, the CPU implementation approximate the result
using three passes, the first two of which are separable morphological
operators applied on the size input. But this approximation does not
provide an advantage because the last pass is non-separable anyways. So
the GPU implementation does not attempt this approximation for more
accurate and faster results.

This simplifies some memory management, ammortizes some of the many
small allocations when building UI layouts, and simplifies the code
that deals with the groups. `uiBlock` is no longer a trivial type.
In my testing this saved a few ms when drawing a large node tree.
Duplicating context lists took a measurable amount of time when drawing

Previously, the code tried to keep node groups working even if some of

Materials without connections to the output node would crash with OSL
in OptiX, since the Cycles `OSLCompiler` generates an empty shader
group reference for them, which resulted in the OptiX device
implementation setting an empty SBT entry for the corresponding direct
callables, which then crashed when calling those direct callables was
attempted in `osl_eval_nodes`. This fixes that by setting the SBT entries
for empty shader groups to a dummy direct callable that does nothing.
Switching viewport denoising causes kernels to be reloaded with a new
feature mask, which would destroy the existing OptiX pipelines. But OSL
kernels were not reloaded as well, leaving the shading pipeline
uninitialized and therefore causing an error when it is later attempted to
execute it. This fixes that by ensuring OSL kernels are always reloaded
when the normal kernels are too.

Attributes are unifying around a name-based API, and we would like to
be able to move away from CustomData in the future. This patch moves
the identification of active and fallback (render) color attributes
to strings on the mesh from flags on CustomDataLayer. This also
removes some ugliness used to retrieve these attributes and maintain
the active status.
The design is described more here: T98366
The patch keeps forward compatibility working until 4.0 with
the same method as the mesh struct of array refactors (T95965).
The strings are allowed to not correspond to an attribute, to allow
setting the active/default attribute independently of actually filling
its data. When applying a modifier, if the strings don't match an
attribute, they will be removed.
The realize instances / join node and join operator take the names from
the first / active input mesh. While other heuristics may be helpful
(and could be a future improvement), just using the first is simple
and predictable.

The problem was the bake function was using the evaluated
data and must use the original data.
The problem was caused by commit: rBcff6eb65804d: Cleanup: Remove duplicate Bake modifier code.
Fix by Philipp Oeser
Editmode should display the original (non-evaluated) points unless there
is something like an "On Cage" option of a modifier [which none of the
curves modifiers have].
This was not the case since the introduction in rBe15320568a29.
So we now draw the editpoints from the original curves. This also means
that original and evaluated curves might not have the same number of
points, so we have to get independent of `proc_point_buf` since that
would possibly create vertexbuffers of different sizes (compared to the
original curves) which is not allowed for a single batch.
- remove the "pos" alias from the vertex buffer format of proc_point_buf
- instead, create a new "edit_points_pos" vertex buffer
- fill that with the original (un-evaluated) curves positions
- dont request `proc_point_buf` anymore
- rename the editpoints flags buffer to be more consistent
And since original and evaluated points might also be in completely
different positions, we also need to draw connecting lines between those
editpoints to not have them float in thin air. For drawing these in
editmode, a simple polyline was chosen (instead of drawing lines in a
resolution that is take from the old particle system -- which is not
depending on points even but has a hardcoded resolution that can only be
upped by the hair_subdiv scene render setting)
- create appropriate batch and indexbuffer for this
- positions vertex buffer can be reused
- reuse particle edit shader (instead of curve edi shader) to get
segment highlighting
{F14055436}
NOTE: this also removes the broken depth handling and instead makes it
work (also XRay is properly taken into account) by binding the correct
overlay framebuffer.
NOTE: to further clarify the distinction between curves drawing (that is
based on the old partice system drawing) and drawing in editmode, the
corresponding vertexbuffers have been moved out of CurvesEvalCache into
CurvesBatchCache directly.
NOTE: drawing the lines in editmode could be improved (taking the "real"
resolution of splines into account, but since this should happen on the
GPU in a compute shader, this is for later)

- Use __slots__ for KeyframesCo as dynamically assigning new members

Apparently the workaround of checking if the mouse is already inside
the area on the next event doesn't work for some tablets.
Perhaps the order of events or some very small jitter is causing this
issue on tablets. (Couldn't confirm).
Whatever the cause, the solution of checking the timestamp of the event
and thus ignoring the outdated ones is theoretically safer.
It is the same solution seen in MacOS.
Also calling `SendInput` 3 times every warp ensures that at least one
event is dispatched.
This adds a new mirror image extension type for shaders and

and domains in order to give the proper order for the UI list.
That is a different than an index in the group of all attributes.

Another option would be to change the way the "attribute index"

be more complex and annoying.

This is essentially a left-over from the initial transition to fields where this was
forgotten. The mesh primitive nodes used to create a named uv map attribute
with a hard-coded name. The standard way to deal with that in geometry nodes
now is to output the attribute as a socket instead. The user can then decide
to store it as a named attribute or not.
The benefits of not always storing the named attribute in the node are:
* Improved performance and lower memory usage when the uv map is not
used.
* It's more obvious that there actually is a uv map.
* The hard-coded name was inconsistent.
The versioning code inserts a new Store Named Attribute node that
stores the uv map immediatly. In many cases, users can probably just
remove this node without affecting their final result, but we can't
detect that.
There is one behavior change which is that the stored uv map will be
a 3d vector instead of a 2d vector which is what the nodes originally created.
We could store the uv map as 2d vector inthe Store Named Attribute node,
but that has the problem that older Blender versions don't support this
and would crash immediately. Users can just change this to 2d vector
manually if they don't care about forward compatibility.
There is a plan to support 2d vectors more natively in geometry nodes: T92765.
This change breaks forward compatibility in the case when the uv map
was used.

The first two dimensions of scrambled, shuffled Sobol and shuffled PMJ02 are
equivalent, so this makes no real difference for the first two dimensions.
But Sobol allows us to naturally extend to more dimensions.
Pretabulated Sobol is now always used, and the sampling pattern settings is now
only available as a debug option.
This in turn allows the following two things (also implemented):
* Use proper 3D samples for combined lens + motion blur sampling. This
notably reduces the noise on objects that are simultaneously out-of-focus
and motion blurred.
* Use proper 3D samples for combined light selection + light sampling.
Cycles was already doing something clever here with 2D samples, but using
3D samples is more straightforward and avoids overloading one of the
dimensions.
In the future this will also allow for proper sampling of e.g. volumetric
light sources and other things that may need three or four dimensions.

While it helps on many scenes, it can be disruptive for existing scenes and
for benchmarks the differences in timing can be confusing. So be a bit more
conservative and only it enable it for new scenes.
This allows choosing the 2d vector type in the Store Named Attribute
node. Similar to byte-colors, there is not a special socket type for this
(currently). In geometry nodes itself, vectors are all still 3d.
The "Loading Asset Libraries" label in the menu would already disappear
before the asset libraries are done loading. It only queried if the
loading was started, not if it was finished. Especially notable when the
asset library was slow to load, e.g. because it is not yet in the asset
index.
The use of a struct for device strings caused the CUDA compiler to
generate byte arrays as the argument type, whereas OSL generated
primitive integer types (for the hash). Fix that by using a typedef
instead so that the CUDA compiler too will use an integer type in the
PTX it generates.

This patch removes the old code and moves the node implementation to

That way we can build a stroke curve of sufficient
length to cover all the verts in the brush radius.
Boundary and corner flags are now stored in their own
attribute instead of in MSculptVert->flag. Note that
the other parts of MSculptVert will eventually become
their own indiviudual attibute (including the ->flag
which is still used by dyntopo).
* Fix memory corruption in sculpt attribute code.
* Fix a few compile errors for particularly pedantic compilers.
* Consolidate a bit of ASAN code in customdata.cc.
* The sculpt code now handles lifetime ownership
of SculptCustomLayer structs. This removes the
need to create temp attributes and get their
SculptCustomLayer reference structs in seperate
steps, as the code can internally update e.g. bmesh
block offsets for all SculptCustomLayer instances.
* Removed ss->custom_layers. The SCULPT_SCL_XXX enums
are no longer used to reference standard attributes
(though they are used, at the moment, to provide names
for them). Instead a new accessor struct, ss->scl,
has pointers to standard attributes (e.g. ss->scl.automasking_factor,
ss->scl.fairing_mask, etc).
This is the final version of the API that will be ported to master
(possibly minus the SCULPT_xxx alias functions that simply call
BKE_sculptsession_XXX equivalents).
Fix the pbvh draw optimization that only sends
active attributes to the GPU. The solution here
is the original sculpt-dev one (somehow this
ended up being removed but not replaced in the
pbvh-eevee patch).
It works by checking every viewport in every
window and if it finds eevee or workbench
in material mode it sets a flag in the pbvh
to forcibly upload all attributes.
Another approach is to simply rewrite pbvh
draw properly inside the draw manager to
begin with.
Save and restore python pointers when
adding or removing customdata layers, this is needed
since tool flags are a customdata layer in sculpt-dev.
Reallocating tool flags shouldn't clear python pointers.
* Fixed two missing break statements.
Amazing what a cascade of bugs this
produced.
* Fixed small bug in BKE_brush_curve_strength_ex.
* The radius scale fix for original normal mode
now applies to all sculpt brushes, not just
the draw brush.
* BKE_brush_curve_strength_ex now takes an argment on
whether to invert the input.
* BKE_brush_curve is now deprecated, it applies prior
behavior of disabling inversion for custom curves
* The standard sculpt brush spot test
API now supports square brushes.
* Supports tip scale x from paint brush.
* TODO: rewrite clay strips and paint
brushes to use standard api.
* Roll texture mapping semi-works.
* Brush mapping (device) curves now use the BrushCurve
API. This prevents having to save a CurveMapping
instance for every single device mapping (of which there
is ~5 or so) in every single channel (>40) for
every single brush (~40-70).
* Fixed regression where temporary attributes weren't being
stripped on file save in all cases.
* Fixed ss->totedges not being set correctly
in all cases. Fixes crash in cloth brush.
* Fix compile errors in alembic and fluid
code.
* Remove a couple of debug ATTR_NO_OPTs.
* Cleaned up a few old bmesh-only pbvh
functions into generic ones.
* Sculpt colors from master is now merged in.
* Implemenation for querying original verts is now
inside pbvh instead of sculpt.
* Still experimental
* PBVHs are cached in a global map keyed by
object name (though at the moment only one pbvh
is cached at a time).
* ss->pmap is now freed managed by pbvh.
* ss->bm is freed by the pbvh cache in some
circumstances but is stilled owned by SculptSession.
* Increased substep count.
* Snake hook now runs dyntopo twice by
inserting it into its commandlist twice,
instead of running over the same nodes and
re-executing it.
* Anchored stroke mode now works with
new brush command system
* Fixed original normal calc for anchored
brushes.
* Added yet more code in my as-yet vain
attempt to enforce seperation of
graphic drivers and ASAN.
backend for BMesh for profiling
purposes
* Purpose is to test the performance of
block vs page vs array CustomData allocation.
* Code is as simple as possible.
* Patches existing BMesh CustomData API.
* Not intended for master.
In an attempt to fix dyntopo artifacts with
snake hook I wrote a new heap implementation
for dyntopo, a min-max heap.
Turns out the seperation of collapse and
subdivision queues was a fundamental design
flaw in DynTopo. Unifiying them in
a single heap is much faster (as much as
2x faster depending on the setup), and
will allow for much cleaner code.
C++ API.
Basic idea is to wrap the C DNA structs
in a C++ wrapper class. Instances of
this class are then passed around by
value.
Rewrote BKE_brush_channelset_get_final_float
and BKE_brush_channelset_get_final_vector to
use these classes. Seems to work, will test
more.
Also, added a bunch of files that git failed
to add in the last merge.
Meed to do a merge so the code is in an
incomplete state. Anyway, I'm going to
move the brush engine code to C++, the
existing C code would never pass code
review.
I figure I can do this incrementally over
the next month or two and then submit a patch.
* Cleaned up naming.
- SCULPT_temp_customlayer_ensure is now
SCULPT_attr_ensure_layer.
- SCULPT_temp_cdata_get is now
SCULPT_attr_vertex_data.
- SCULPT_temp_cdata_get_f is now
SCULPT_attr_face_data
- SCULPT_temp_customlayer_get is now
SCULPT_attr_get_layer.
* Replaced with ss->limit_surface with an
entry in ss->custom_layers.
cache
* Fixed a few bugs in the curvemapping
cache code.
* Fixed bug in how BKE_channelset_compat_load
was copying brush.curve to/from the falloff_curve
brush channel.
now atomic
* bke_pbvh_update_vert_boundary now uses atomics
* This allows dyntopo surface smoothing
(surface_smooth_v_safe) to update vertex boundary
flags inside of a thread. This lessens degenerate
geometry created by hard edged brushes like
clay strips.
Two new automasking modes: "Brush Normal"
and "View Normal."
Brush Normal compares vertex normals to
the initial sculpt normal, while View
Normal of course compares with the
view vector.
Each of these modes have an angular limit
and a falloff. There's also an "original
normal" option, which needs a better name;
"original normal" is actually already taken,
but "automasking original normal" is a lot of
characters. Not sure what to do here.
This brush goes through all
the grids inside each PBVH node under
the brush, converts coordinates to
tangent space, filters out extreme displacements
and then converts back.
Simple, but very effective.
TODO: make this into a mesh filter too.
* BKE_brush_add now calls BKE_brush_sculpt_reset if
ob_mode has OB_MODE_SCULPT set. This should hopefully
eliminate a whole class of bugs I've been chasing.
* Detail enhance is now it's own dedicated toolslot.
This makes it possible to use autosmooth with
detail enhance.
Note the behavior of the smooth brush (which
invokes enhance when pressing control)
is unchanged.
* Fixed a bug with temporary attribute layers being constantly
cleared and reallocated with multires.
* Cleaned up velocity smooth code a bit.
* Pruned various dead #if blocks.
* generate_from_enum_ex in space_toolsystem.py
now takes a special argument to combine enum
items. This is used to make enhance a subtool
of smooth.
* The "boundary smooth" (psuedo-bevel) functionality of
SCULPT_neighbor_coords_average_interior is now its
own function.
* Fixed a few more pedantic gcc errors.
* Volume preservation had wrong bounds in
elastic deform brush leading to wrong
behavior.
* Fixed unprojected_radius channel not
being shown in header when scene radius
unit is on.
* Draw face sets now only fully rebuild draw buffers
in indexed draw modes that require it.
in weighted smooth
* Cached face areas are now updated
in a double buffered fashion;
all threads read from one side of
the buffer while the other is written
to by the threads that own a given
face; the buffers are swapped on
each iteration of a tool that uses
face areas.
* Fixes smooth flickering.
* This was actually kind of annoying; the
vertex->face-area-list code is in pbvh and
relies on edge ordering
around verts, but that order is non-trivial for
PBVH_FACES (relying as it does on a vertex->poly
map). This ordering was calculated entirely in
editors/sculpt_paint/sculpt.c, not callable from
pbvh.
* The solution was to add a helper function to pbvh
for building vertex->edge lists from vertex->poly
maps. This is then used by both sculpt.c and the
vertex->face-area-list code.
* Also improved boundary bevel smooth a bit. I'm
thinking of extracting it from SCULPT_neighbor_coords_average_interior
into its own function and possibly its own brush.
* Paint now has a brush_eval field which
is used in leu of ->brush if non-null.
* This lets us get rid of all the annoying:
`brush = ss->cache ? ss->cache->brush : BKE_paint_brush`
code. Now it's just BKE_paint_brush.
* Used by SCULPT_run_command.
* Also fixed nasty scene spacing bug.
* Fixed PBVH_FACES vcol draw bug.
* Fixed boundary smooth being turned on
if its temp customdata layer exists.
* Fixed unnesting of brush panels from
last commit improperly showing up
in the workspace tab for sculpt
instead of the brush tab.
related fixes
Various fixes so sculpt_init_tool_override_channels
for shift-smooth can replicate the prior behavior:
* Brush spacing will now look up brush channel
spacing directly for sculpt, instead of relying
on copying the channel data into Brush.
* Brush spacing code will now use brush channel
pressure for sculpt. Fixes broken shift-smooth
pen pressure.
* The falloff_curve channel is now automatically
added (before it was only used internally by
command lists, the code was defaulting to
the Brush field otherwise).
* BrushCurve now has an option for custom curve
presets to have negative slopes.
* The Falloff panel now puts the type dropbox
inside the panel header.
* Falloff panel also now uses brush channel data in
sculpt mode.
* falloff_shape is now a brush channel
In a somewhat unrelated change, I also unnested the
Brush Settings subpanels. It's been driving me
insane for a very, very long time. Much more
usable this way.
* Fixed bug where BRUSH_MAPPING_INHERIT was
being or'd to BrushMapping->flag instead
of assigned to ->inherit_mode.
* Fixed smooth_strength_factor
and smooth_strength_projection.
* Also added yet more asan poisoning to mempool
* Added a function to build final inherited brush
channel, BKE_brush_channel_copy_final_data. Takes
BrushMapping->inherit_mode into account.
color filter options from
sculpt-mode-features
* Follows comment in mesh filter's randomize and
uses BLI_hash_int_3d.
* Added a seed parameter.
* Also renamed SCULPT_get_mdyntopo to SCULPT_get_sculptvert.
* PBVH drawing for eevee is now used for
PBVH_FACES as well as PBVH_BMESH.
* PBVH_FACES now uses pbvh draw for eevee rendering
* Refactored gpu_pbvh_gpu_make_vcol_offs into a
more general gpu_pbvh_gpu_make_attr_offs.
This should be a usable alternative to using a generic
attribute gpu system (whether the one that's #ifdef'd out
in gpu_buffers.c, or the new one that hit master
recently).
* Textured workbench draw mode now works for pbvh drawing.
* Fixed nasty stack overflow in dyntopo edge collapse.
* Mask by color now works for dyntopo.
* Attribute and vertex color lists in the UI
now hide temporary CD layers.
* Added a specific op for removing vertex color
attributes.
* Fixed various bugs.
It simply wasn't maintainable to store active/render
vertex color layer as integer indices into the
global attribute list. Making that work would've
required a great deal of boilerplate that would
have to be inserted in lots of places. There
is simply no justification for doing that.
Instead, I've coded an AttributeRef struct that
simply stores a (type, name, domain) triplet to
uniquely reference an attribute layer.
This will be submitted as a patch for master
too.
* Brush input mappings now have three
inheritance mode: "always", "never" and
"channel" (use channel's inheritance mode).
* Note that the UI exposes a single inherit icon,
which just toggles between "always" and
"never," to lessen user confusion.
* Brush mappings default to "never" inheritance
mode.
* Fixed wrong node update flag in bke_pbvh_insert_face_finalize
leading to disappearing parts of the mesh.
* PBVH_BMESH construction is now partially
threaded.
* Fixed n**2 behavior in freelist-based
bmesh id implementation. I'd really
rather get range-tree faster, but
this works as a stopgap.
* Removed a bunch of debug ATTR_NO_OPTs.
* Mesh now has a render_color_index member.
+ We really need an attribute ref system
based on (domain, type, name) triplets.
* RNA uses render_color_index in all three
cases (loop colors, vert colors, and
the generic attribute types).
* PBVH draw uses render_color_index too.
UI list.
* Added an index to Mesh for active color attribute.
This seems janky to me, shouldn't this (along
with the active attribute index) be a
domain, name, cdtype triplet?
* Added a little api to preserve the active attribute
and color indices when changing mesh customdata
layouts. See above comment.
* The vertex color panel is now completely unified.
* TODO: allow setting render color layer (not sure how
to do this).
* Sculpt.brush_stroke now has a property to override
the tool slot.
* Note that this is somewhat different from how this
was typically done in the past. Instead of physically
switching slots we instead load the overriding slot's
brush's channels into ss->cache->tool_override_channels.
Basic idea is based off of {D6515}
* Removed a pointer from a sculpt cloth struct.
Due to padding this doubled the size of the
struct. Hopefully this will be nicer on the L3 cache.
* Fixed a nasty memory leak in the smoothing code with multires.
* Sculpt viewport header is now auto-generated in
much the same way as the workspace buttons
and right click menu.
* Added an API in the python code to insert
bits of UI code after a brush channel, currently
used to add flip colors operator.
* Added icon to add brush channels to header in
brush edit mode.
* Updated input mappings UI.
* BMLog now saves face material indices
* Fixed id corruption in join mesh edge case.
* The mesh->bmesh conversion function now checks
if IDs are corrupted in a bit smarter way:
+ Any id that's greater then 5 times the sum of
total elements with ids is assumed to be corrupt.
Avoids very large allocations for the fast element->id
map, which is a simple lookup table.
+ Alternative is to automatically switch to the slower
GHash id->element map.
+ Sculpt code would have to detect this case and regenerate
IDs?
* The slide relax brush is now internally split into two
seperate commands.
* Basic smoothing now uses fewer iterations, velocity smooth
is used to speed up convergence.
Added a new "auto face set" setting for brushes.
It basically invokes the draw face set tool,
with a few differences:
* The painted face set is fixed by user setting.
* More then one face set can be created,
these are assigned based on distance to
the stroke line.
* TODO: write a proper API for wrangling stroke
curves (should interpolate at least G2!).
The point of this is to enable better hard surface
brushes. Since the settings are extremely finicky
I've added an example of one (based on clay strips)
to startup.blend.
The necassary steps to make a hard brush out of this
are as follows:
1. Autosmooth: ~0.4;
2. Autosmooth radius scale: ~1.5.
3. Auto fset: on.
4. Hard edge mode: on (but turn off inherit).
How silly of me. I had left on
some debug code I wrote for edge collapse.
This particular debug code generated a .obj
format string of the local mesh around an edge
before collapsing edges.
What amazes me is that the performance regression
was only about as bad as the original edge collapse
implementation in DynTopo.
other fixes
* The paint brush now supports accumulate.
* Fixed bug with PBVH_FACES not setting
MSculptVert update flags correctly in
face set draw brush.
* Topology rake now has a mode where it
simply propegates directions from
boundaries.
* Dyntopo is now run before other commands in the
brush command lists.
* Fixed nasty command subspacing bug.
* Added a missing RNA library override flag.
* You can now edit brush input mappings
inside the main workspace brush panels.
* PBVH_CHECK_NAN now limits how many reports
it prints from a given source file.
* Fixed various problems with shift-smooth strength
setting.
* Fixed a NaN in the smoothing code.
* Fixed a nasty bit of memory corruption
* Along the way, added ASAN support to
bmesh customdata blocks.
* Each CD layer is padded by 32 bytes
inside the bmesh data block.
* Also fixed a few minor errors in
mempool's asan support.
* Tried and failed to fix numerical
stability issues with lasso/box
trim brushes.
* Input mappings now take a premultiply factor
to scale the input data prior to evaluation;
* Mapping data can also now be fed through a
(wave) function prior to evaluation.
* The UI now has seperate inputs and outputs
sections for input mapping to avoid confusion.
* Added a distance mapping and implemented the speed
mapping.
* Also fixed original data bug in color filter.
Cleaned up brush channel input mappings:
* BrushMapping now stores .min/.max
* BrushMappingDef .min/max now sets BrushMapping min/max
instead of changing the curve preset bounds.
* Fixed how BKE_brush_channel_eval_mappings evaluates
the mappings stack. Mappings now blend directly
with channel value instead of accumulating a multiplier
that's applied at the end.
* Consequently, BrushMapping->blendmode now defaults to MA_BLEND_MULT.
* Exposed BrushMapping->blendmode in RNA and UI.
Note that it doesn't support every MA_BLEND_ type,
it provides its own EnumPropertyItem list of
supported blendmodes.
* Added a random input method, BRUSH_MAPPING_RANDOM.
* Fixed BRUSH_MAPPING_ANGLE being given data in the wrong
range (all channels should be 0..1, not -pi..pi).
Other changes:
* Improved the uv smooth brush. It's still hidden behind an
experimental pref.
* Added a SCULPT_temp_customlayer_has function to check if a temporary
customdata attribute layer exists.
* Fixed a bunch of broken sliders in the paint_toolsystem_common.py.
* Wrote a new function, SCULPT_reproject_cdata,
to reproject loop customdata after smoothing.
* SCULPT_reproject_cdata is only called if UV
layers exist.
* All of the smoothing tools (hopefully all)
use it.
* This change is necassary to properly support vector
displacement maps in the future; otherwise DynTopo
will introduce lots of noise into the uv tangent
space.
Most of this commit made it in one or two commits ago.
Added a little macro to detect mysterious NaNs reported
by users and that appear to be related to threading.
It's seeded in various places to hopefully catch
where this is happening.
* Paint brush now uses its own temp attribute
layers instead of hijacking MSculptVert->origcolor.
* The various SCULPT_UNDO_XXX enums are now bit flags.
* Fixed anchored/drag drop mode for the paint brushes.
* Color hardening brush now works with dyntopo.
* Added a CD_FLAG_ELEM_NOINTERP flag to the customdata
API. If set it will either copy the first element
in the sources list if CD_FLAG_ELEM_NOCOPY is unset,
or nothing at all if it is.
This necassary to properly support the design
pattern whereby helper custom attributes
reset themselves in each brush stroke by comparing
a per-vertex stroke id with ss->stroke_id, thus obviating
the need to walk the entire mesh at every stroke start.
This commit rewrites much of the core BMLog
serialization logic.
BMLog originally did not support mesh
elements changing their internal topology,
which created ID conflicts in the log. Thus
it was impossible to use much of the BMesh API.
Instead DynTopo had its own implementations of
BM_edge_collapse and triangle edge splitting
that worked by recreating local mesh topology
from scratch.
I got rid of these functions a while ago and
tried to add support for elements changing
topology to BMLog. Unfortunatey I struggled to work
out all of the edge cases, and it turned out easier to
refactor the core serializer methods wholesale.
vertex color drawing.
* Added two buttons to toggle between vertex
and material color modes in workbench drawing
mode.
* They are labeled "Colors" and "Normal" to
avoid confusion; "Vertex" is ambiguous, while
"Material" might be taken to impley "EEVEE."
* For now they only show up if a sculpt paint
brush is active.
* Updated startup.blend so the sculpt layout
has vertex drawing mode on by default.
* BMLog now has a more fine-grained logging
facility to track the call chains
that produce specific log elements.
* Wrote a new function in bmesh_core.c to
dump local geometry around an element to
stdout in .obj format.
* Edge collapse now properly handles the
fact that bmesh handles sharp flags
inversely, i.e. edges *not* marked
with BM_ELEM_SMOOTH are sharp.
* Wrote a new BMLog API that handles elements
undergoing topological changes a bit better.
- BM_log_[edge/face]_[pre/post]
- Idea is to call the _pre before calling
collapse or split edge, then _post afterwards.
- No longer need to assign new IDs
in certain cases to avoid confusing BMLog.
- Other parts of BMLog may now be redundant;
need to check.
* Deleted some #if 0'd code
* Fixed a bug in BLI_smallhash_ensure_p, it didn't properly
set up state for when smallhash is used as a very simple
set.
* Fixed the completely broken shapekey conversion
in BM_mesh_bm_from_me; this bug is most likely
in master as well.
* Note that, while shapekeys now work in dyntopo
it does not represent a complete sculpt layers
implementation; the layers are still stored in
world space.
* The motivation for fixing this was to keep
dyntopo from destroying shapekey data, which
was the only form of custom attributes it didn't
support.
* That was because shapekeys were never being converted
to custom attributes for bmesh to begin with, the
conversion code was quite broken.
In addition to all this, this commit also has
a fix dyntopo collapse fixes.
* BM_edge_collapse now has an option to use
a new collapse implementation that can
handle non-manifold geometry properly.
* The aforementioned implementation is a replacement
for bmesh_kernel_join_vert_kill_edge. Note that
the old code still exists as
bmesh_kernel_join_vert_kill_edge_fast and is used
by default.
* This was always buggy, which is why
I have code that detects and snips off
non-manifold fins.
* Turns out it is more robust to simply allow
non-manifold collapses and clean up geometry
afterwards. IIRC this is how DynTopo (and the
paper it's based off of) originall worked.
* Paint brushes will now support
dyntopo if "dyntopo disabled"
(the one in their brush settings,
not the global setting in the
"Dynamic Topology" panel) is unchecked.
* Fixed dyntopo undo not properly handling
pushing more then one undo type.
This one is an actual error. I
went through the trouble of compiling
in a linux VM and still somehow managed
to miss it.
Also fix wrong range for normal_radius_factor.
interface to mask expand in "selection"
mode.
Leftclick runs normal expand.
Shfit-leftclick subtracts from mask.
Pressing CTRL inverts adding/subtracting
* The dyntopo collapse function now
properly snaps UVs, including at
island boundaries.
* PBVHTriBufs are now split by UVs
(and face sets); this turned out
to be surprising easy.
* Also fixed a few bugs relating to
hiding/revealing stuff.
* Brush radius wasn't being calculated correctly if symmetry was on.
* Unnessed SCULPT_run_commandlist, it now calls
do_symmetrical_brush_actions instead of the reverse.
* Renamed MDynTopoVert to MSculptVert. Old name didn't
make sense given that all three PBVH types now use it.
Mercifully it's never saved in files, and even if it
somehow was saved the CD file loading code checks for
that.
* Fixed very nasty customdata bug where
if the first layer of a given type was
CD_TEMPORARY, then on being stripped out
of the customdata set the active references.
I think I tracked down where this happened, but
just to be safe I also wrote code to detect it and
regenerate the active refs too.
* Fixed rotate brush.
* Fixed mesh filter crashing with automasking on.
Face set extrude now mostly works, thought it's
still buggy and unstable in DynTopo mode.
Interfacing PBVH_BMESH with the BMOp API
turned out to have a few nasty gotchas; the last commit
fixed a lot of things but some rethinking of the basic
design still needs to happen.
The way toolflags reallocated the entire mesh
just to add or remove one pointer from BMEdge/Vert/Face
was highly broken. Now a CD layer is used instead.
* PBVH_UpdateTopology is now properly cleared in all cases.
* BKE_curvemapping_cache.h no longer provides a global curve
cache, the brush system now allocates its own on startup.
* BrushChannel now uses its refine callback to
generate new structs for individual BrushChannelType's.
- It generates a .value member that's a copy of
one of the exisitng float_ bool_ enum_ etc_value members.
- Haven't figured out how to delete the XXX_value members
yet though.
* Drag dot now uses anchored's method
of calculating brush rake angle, this
is much more usable and less numerically
unstable.
* There is now an option ("Smooth Raking" to
smooth rake angles during brushes. This was
a failed effort at fixing drag dot raking
that turned out to be useful for other things.
* Drag dot no longer requests subspacing events
from the brush system. This made a huge
difference in performance and is now on par
with anchored mode.
GCC is giving errors on assigning
integers to char arrays. Naturally
this makes sense, and of course MSVC
doesn't even have a warning to detect
this (I tried enabling them all).
I may go back to clang.
For some reason I have to
take the sqrt of pressure
to match previous behavior,
but for the life of me I can't
find the offending double
multiplication.
* PBVH_FACES now uses MDynTopoVert (have got
to rename it) to store boundary/corner/visibility
flags the same way PBVH_BMESH does.
* Fixed brush add/sub buttons in header not
working
* Fixed inverted brushes feeding negative strength
to sub commands (like autosmooth, which flips it
to sharpen mode).
* Brush editor tab now defaults to old
interface, with two options:
- Advanced, which shows more options
- Edit Mode, which shows workspace visibility buttons
* Hard edge mode (which forcibly sets face set slide to 0
and enables preserve faceset boundarys) now works again.
* Smooth_strength_factor is now a brush channel with
inheritance set to true.
* Alt-smooth now restores the hard edge mode and
smooth_strength_factor from the active brush context.
While both are default inherited from toolsetting defaults,
it can be quite confusing if either have inheritance unset
by the user in the Smooth brush.
* Fixed a particularly nasty memory leak
where the entire process of entering sculpt
mode was being done twice.
* Discovered that range tree is extremely slow.
Got the alternative freelist version up and running,
and replace a usage of GSet with a bitmap. However
the new code is disabled pending further testing.
Literally an order of magnutude improvement.
* Cleaned up the SculptCustomLayer API that is
used for custom data.
* Various SculptCustomLayer references are now maintained
in ss->custom_layers and are updated automatically when
the CD layout changes.
* PBVH_GRIDS now forcibly allocate custom layers in simple_array
mode (i.e. they don't allocated real customdata layers at all).
* SculptCustomLayers can optionally be preserved in the final mesh.
* Fixed handling of CD_TEMPORARY which was broken.
* The layer brush can now split the pbvh during use.
* Persistent base data is now saved as permanent CD layers (except
for PBVH_GRIDS). This is necessary for undo, if we want we can
add special code to remove them on exising sculpt mode.
* The layer brush now uses the SculptCustomLayer API instead of
having seperate bmesh and faces/grids implementations.
* In unrelated changes, fixed curve presets for clay brushes.
- Still need to implement stabilized input mappings, which the
clay thumb brush needs.
* BrushChannelSet is now a pure collection. This
eliminated the annoying brush.channels.channels
paths, and also makes library overriding work.
* Now sure I've done this correctly. Struct extended
collection properties are a bit confusing.
* Move more dyntopo settings to brush channels
* Implemented the unprojected radius hack in
the new brush system. I'm not really happy
with it, but doing it properly is going to
take some thought.
* Added a new curve brush channel type
* Added a BKE_brush_curve_strength_ex method
that just takes preset and curve as arguments,
instead of pulling them from Brush.
* Autosmooth and topology rake now have their
own falloff curves.
* Moved brush settings (in sculpt mode) to
(for now) a new properties editor tab.
* Brush settings can now be individually configured
to show up in the workspace buttons.
* Brush settings can also be reordered.
* The new brush tab has a "preview" subpanel
to preview the workspace settings layout.
This is where settings are reordered.
* Sculpt now has an API to get brush channel settings.
If a sculpt cache exists it will use the channels there
(ss->cache->channels_final), otherwise it pulls them
from a brush and Sculpt toolsettings. Exampes:
float f = SCULPT_get_float(ss, "setting", sd, brush);
itn i = SCULPT_get_int(ss, "setting", sd, brush);
* Improved the UI a bit
* The input device curves for brush channels
now use a copy on write mechanism.
+ It's based on a global cache of curves.
The alternative is to reference count
BrushChannels, which I also implemented
then abandoned.
+ Profiling showed that copying CurveMapping
instances was actually a problem.
* Lots of small fixes to the old<-> new brush setting
conversion code;
* Brush commands can now, sortof, have individual
spacing. The default brush spacing still acts
as a minimum though.
* Added a BLI_ghash_lookup_p_ex method that
returns the key ptr inside the ghash (it
returns the actual key, not a pointer to
Entry.key).
* Added a general 1d CurveMapping preset operator
that uses an RNA path to get the curve.
BrushChannels are now stored in linked lists
instead of simple arrays. This helps to
avoid memory corruption.
I had originally wanted to be able to pass
BrushChannels by value, but that doesn't really
work since they heap allocd data (the input
mapping curves).
Command Lists
* The new system will be based on command lists
generated by (eventually) a node editor.
* For now, the lists will be hardcoded.
* Idea is to make a minimal viable
brush engine that won't cause file breakage
when the upgrade to node-based brushes happen.
Brush Channels
* Wrote new structures and API to wrange
brush parameters: BrushChannel.
* Supports, floats, ints, enums, bitmasks,
with plans for vec3 and vec4.
* This will replace UnifiedPaintStruct,
most of the members of Brush and the
DynTopoSettings struct.
* Brush channels can
be mapped to various input device
channels (e.g. pen pressure); each
mapping has its own associated curve
(CurveMapping instance) and bounds.
Brush channel inheritence chaining
* Brush channels can form inheritence chains
* Channel sets are stored in three places:
in the scene toolsettings, in Brush, and in
individual brush commands.
* Node groups will also have a channel set.
* Channels in each set can be flagged to
inherit from the parent set.
* Inheritence happens in seperate merged
channel sets at runtime. The final
Brush channels live in Brush->channels_final,
while the final command channels live in
BrushCommand->params_final.
design study (note that it's #ifdef'd out).
Basic idea is to put all the sculpt brush code
in a single large template. This template
takes a PBVH adaptor class (of which there
would be three, one per PBVH_XXX type)
as a template argument.
Basically we're using the compiler to generate
three complete copies of every brush implementation.
C++20 concepts are used to validate the pbvh classes.
An example brush implementation:
pbvh->forVertsInRange(
{
.brush = ss->cache->brush,
.radius = radius,
.use_threads = true,
.use_original = false
},
[&offset](auto viter, int node_i, void *userdata) {
//add offset to vertex coordinates
madd_v3_v3fl(viter.co, offset, viter.fade);
},
[](PBVHNode *node, int node_i, void *userdata) {
BKE_pbvh_node_mark_update(node);
});
Seperate enabling PBVH_BMESH from enabling DynTopo:
* Created a new option to globally disabled
DynTopo.
* The DynTopo panel header now reads "Dynamic Mode",
to hopefully signal that turning on PBVH_BMESH is
a seperate step from enabling or disabling DynTopo
itself.
* The first checkbox in the panel is "DynTopo" so it
should be clear enough (it's on by default, with multiple
layers of file versioning checks).
PBVH_BMesh's undo system:
* CD_MESH_ID layers are now permanently saved once
they are created (by default they are not). This
fixed a *lot* of bugs:
Before this the undo system had to save maps between
mesh indices and mesh IDs on transitioning
between sculpt and global undo steps. This was
extremely error prone, and it simply wasn't possible
to cover all of the corner cases
* Note that there is still an odd bug where the first
global undo push after a sculpt step gets ignored,
I dunno what's up with this.
* Dyntopo undo should be nearly (hopefully completely)
bug-free after this commit.
C++20
* Made a few small changes to get blender to compile
with c++20. std::result_of was removed, had to
replace a couple of usages of it with std::invoke_result.
* I'm planning to do some design studies on rewriting
sculpt into C++.
* I strongly suspect we are going to need C++20'a new
concepts feature if we move sculpt into C++.
I'm planning to do some design studies on how
that might work.
* Fixed noise on using autosmooth with tools that use original
coorinates. While this was most prominent with DynTopo,
it did happen with other tools.
* The solution is to smooth the original coordinates as well
as the explicit coordinates if the active tool requires
original data.
* I decided to replace the original coordinates system for
PBVH_FACES and PBVH_GRIDS with the same MDynTopoVert structure
DynTopo uses. The alternative would have been extremely messy
code.
* Todo: Rename MDynTopoVert to. . .SculptInfoVert?
* Todo: Cache boundary flag and corner info in MDynTopoVert->flag
for PBVH_FACES/GRIDS similar to PBVH_BMESH.
* Collapse now uses code from decimate to detect
degenerate cases.
* Remaining, unknown (and rare) degenerate cases
are now detected (via presence of duplicate verts
in faces) and fixed.
* DynTopo fills in undo size properly now,
so undo memory limiting works.
* BLI_table_gset now internally uses a SmallHash instead of
a GHash. Profiling revealed this to be quite a bit
faster.
* This is something of a stopgap until C++-afication of
pbvh, when we'll have our pick of a bunch of
really nice C++ hashmap libs.
* pbvh_collapse_edge bites the dust; dyntopo now uses
BM_collapse_edge. Of the three topology operations
(subdivide edge, collapse edge, dissolve 3/4 valence
vertex) only dissolve still has a dyntopo-specific
implementation.
* Fixed a bunch of annoying memory corruption bugs.
* Non-manifold triangles are now detected in more
places.
SmallHash changes:
* Enabled removal
* Fixed infinite loop bug caused by
improperly counting free*d* cells
versus free cells.
* Added a BLI_smallhash_ensure_p method
that works just like the GHash version.
Sculpt replay system
* Roughed out a simple system to record and
play back sculpt strokes using a simple
text format.
* This is exclusively for
performance profiling and unit tests.
* For each brush stroke the system saves a copy
of the active StrokeCache and PaintStroke
and parts of Sculpt.
This should make profiling DRAM thrashing a lot
easier.
* Changed brush defaults a bit. New defaults
are for organic modeling.
* autosmooth_fset_slide now defaults to 1, so
face set boundaries are smoothed but stick to mesh
surface (if 0 they would function as hard edges).
* Weight by area smooth mode is on by default for all
brushes.
* Cleaned up versioning code and made it
kick in at 3.00:21, with some simple checks to
try and detect existing data from beta testers.
* Also fixed a small crash bug.
* Wrote a simple fix for drawing face sets
in inverse (ctrl) mode with face set automasking
on.
* Various fixes related to hard edges and smoothing.
* Started writing some code to defragment bmesh mempools.
Need to figure out how to avoid triggering excessive
PBVH node rebuilds.
I might write a paper on this. Topology rake now locally
updates a vector field, which it uses to smooth the input
and constrain to mesh (including face set) boundaries.
This can make an enormous difference for things like
smoothing.
Note that this is different from the existing 'curvature rake'
mode, which also builds a field and which is fed into the input
of this new one.
The only oddity is that the field is stored in a CD_PROP_COLOR
since we don't have a CD_PROP_FLOAT4, and this shows up in the UI
(not sure if I'm messing up the CD_TEMPORARY flags or if the UI
doesn't check for them).
* Fixed crash in dyntopo collapse. The
loops around vertex iterator dyntopo uses
doesn't actually work on non-manifold meshes,
or meshes with invalid normals, this was not
being checked in pbvh_bmesh_collapse_edge.
* Rotate tool now works with dyntopo.
* Added a minimal edge API to query edge
boundary states.
* This is necassary because the previous approximation,
testing if two adjacent verts are boundaries, breaks
for triangles.
Added an option to split face set boundaries on mirror
boundaries; currently only DynTopo supports this.
Very useful for making hard edges along mirror lines.
* Sharp edge flags are now supported and are
treated much the same as face set boundaries:
+ Dyntopo preserves them
+ Interior smoothing treats them as boundaries
+ Corners are detected and pinned in smoothing
+ TODO: add a brush flag to ignore sharp boundaries
for smoothing.
* Seams are also preserved, but don't affect smoothing.
* BMLog now saves edges.
* The new edge split function is enabled.
* Dyntopo now pushes new combined BMLog entries in
its top-level function, to avoid scary id reuse
edge cases.
* SCULPT_vertex_is_boundary/corner now take a bitmask
of which types of boundaries you wish to query instead
of check_face_sets.
* New function SCULPT_vertex_is_corner, similar to
SCULPT_vertex_is_boundary it takes argument to
check face sets. PBVH_FACES/GRIDS version is
incomplete. It returns a bitmask of whether
the vert is a boundary corner and/or a face
set one.
* PBVH_BMESH uses a somewhat more expensive
calculation to detect corners of face set islands by
edge angle. This is currently not done for boundary
corners.
Corner pinning now happens in:
* The internal smoother dyntopo uses for stability reasons.
* SCULPT_vertex_neighbor_average_interior.
* Topology rake.
* Dyntopo collapse.
Note that DynTopo always pins face set corners
but everything else only does so if preserve face
sets is on.
* All of the smooth brushes now use the SculptCustomLayer
system for temporary data, so all work with dyntopo now.
* You can now use a flat array in SculptCustomLayer with
PBVH_BMESH (though you have to build the structure manually).
The mesh filter code uses this.
* Smooth (and autosmooth) now have an option to preserve face
set boundaries. Corners are currently not handled.
* Simplify brush has preserve face set boundaries autosmooth
flag set by default.
* SCULPT_vertex_is_boundary now takes an addition argument
for whether to check for face set boundaries.
* Added an option to weight smooth by face areas
* Dyntopo now caches face areas in a CD_PROP_FLOAT layer
* Dyntopo also caches number of edges around verts inside of
MDynTopoVert. To avoid increasing the struct size flag was
made a short.
* Cleanup mode (dissolves 3/4-valence verts) now piggybacks on
subdivide code to build list of verts; this is much faster.
To run, in the python console enter:
bpy.msgbus.pbvh_bmesh_do_cache_test()
The output will be in the regular console. The test
build a half-million vert cube and smooths it. It runs
several passes (all of which perform the same smoothing
operation):
1; Randomized order pass
2. Ordered pass (by vertex clustering)
3. Same as 2 but with a purely data-oriented version
of the bmesh structs.
4. Same as 2, but using a version of the bmesh structs
with all pointers replaced by integer indices.
At least on my laptop #3 and #2 are about a third faster
then #1, and #2 tends to be around 15%.
* Fixed multires apply base feeding bad original coordinates to
deform modifiers.
* Roughed out some code for cache performance testing.
* Wrote skeleton code for a PBVH texel API; hasn't been tested
yet and may be removed.
* Added a limited "fast draw" mode to pbvh drawing
that tries to limit data sent to the GPU.
- Facesets and mask data are disabled.
- Indexed mode is forced.
- Does not work (at all) for multires.
* Finally fixed some outstanding bmesh sculpt undo bugs:
- Forgot to mark pbvh nodes to update their bounds, which
produced a bug I had thought was caused by something else.
- Hopefully fixed a long-standing occasional memory corruption
bug.
This commit fixes boundary brush for multires which
broke two commits ago.
This required implementing the geodesic api for PBVH_GRIDS,
which I did by building topology maps in a rather. . .
haphazard fashion.
Basically I built a vert->edge map and then used it to
derive a pseudo edge to quads mapping (it maps edges
to all the verts in the two surrounding quads except
the edge's own verts).
Just for fun I enabled geodesic mode in mask expand;
it seems to work.
(still a wip)
The boundary brush now builds a geodesic distance
field (from the boundary) from which it derives a tangent
field:
* These now define the rotation plane for bend mode.
* Rotation origins snap to these planes.
There is also typedef'd code for visualization tangents
in a temporary object (note the sculpt object), to enable
define VISBM in sculpt_boundary.c. This will be removed
lated.
Additional changes:
* Added a function to get the number of edges around verts,
SCULPT_vertex_valence_get.
* Added an API to calculate cotangent weights for vert fans,
SCULPT_cotangents_begin (call in main thread first) and
SCULPT_get_cotangents.
* Sculpt neighbors for PBVH_FACES now uses ss->vemap if it exists.
* The Mesh topology mapping code now takes extra parameters for
sorting vert/edge cycles geometrically.
* Similarly, there is now a function to sort BMesh edge cycles,
BM_sort_disk_cycle.
* MDynTopoVert->flag now has a bitflag for when the disk cycle
sorting needs to be redone, DYNVERT_NEED_DISK_SORT.
* The sculpt geodesic code now supports passing in custom vertex
coordinates.
* The geodesic API can also build an optional map of which vertex
in the initial vertex list is closest to any other vertex.
* The PBVH draw subsystem is now told whether any viewports
have drawtype >= OB_MATERIAL before anything in any windows
are drawn. There are no alternatives given the design
constraints of sculpting, where simply uploading data to the GPU
quickly becomes a bottleneck.
* Fixed flat vcol shading mode.
Also:
* added BMLog function to save mesh IDs.
- Used by SCULPT_UNDO_DYNTOPO_BEGIN/END instead of
saving the whole mesh, which was the previous behavior.
* SCULPT_UNDO_DYNTOPO_BEGIN no longer pushes a non-dyntopo
geomtry undo node, as this is no longer necassary.
This greatly speeds up going into/out of sculpt mode
with dyntopo enabled, as before it was copying
the mesh twice.
* PBVH_BMESH now supports faces other then triangles;
* Dyntopo triangulates faces as it finds them.
- I looked into methods of preserving quads and failed to
find anything that worked well in practice; it actually
worked better to use topology rake to align triangles
into quads and then mark diagonal edges for later dissolving
then to try to preserve quads explicitly (I've not
implementated that here, that was research code).
- To avoid excessive cache-destroying loops over vertex-faces,
DynTopo flags which verts have non-triangle faces.
* PBVHTriBuf now builds edge buffers so we can avoid drawing
tesselation phantom edges.
* BMLog also now supports arbitrary faces. It still does not
support edges though.
TODO:
* Fix vcol cell shading mode
* Make sure indexed drawing works
* Face set boundaries are now preserved on dyntopo remeshing.
* MDynTopoVert->flag now has a DYNVERT_FSET_BOUNDARY flag
in addition to DYNVERT_BOUNDARY.
* Instrumented uiBut with ASAN poison regions to hopefully
find the super evil memory corruption bug that's been driving
me insane. It's frustratingly intermittent. There are five
poison regions.
* Prototyped a threaded bmesh->Mesh converter function. It's about
20-30% faster. Currently disabled.
* Tried to fix more of the bugs when stepping between sculpt and
other undo step types in the global undo stack.
instead of leaving that to the client.
Also semi-fixed uninitialized memory bug in bmesh unit test (dunno
how best to memset a C struct in C++ won't won't run afoul of some
random compiler somewhere).
It uses a simple LSCM-like solver; hold ctrl to do simple
laplacian relaxation.
There are some interesting artistic possibilities to using
DynTopo with UV maps, the point of this tool is to help
explore them.
Note that I'm not planning to merge this into master with
the rest of this branch. When the time comes I plan to
move it into a new branch for sculpt research stuff.
pbvh drawing.
* Dyntopo now stores a list of PBVHTriBufs in leaf nodes, one per material
used by the node.
* Actual drawing buffers live in a new mat_draw_buffers PBVHNode member.
A few notes:
* MESH_ID layers are not saved on conversion to Mesh unless
you ask for it in BM_mesh_bm_to_me's params.
* Still need to test the box/lasso trim tools.
* Need to find some way to test loop/edge ids, which aren't
used by dyntopo.
layers to a bmesh at once. Helpful since bmesh customdata
layers are allocated in single blocks, thus adding
layers individually can lead to lots of memory
copying.
bmesh
* System is per element type. So you can have unique ids for verts and
faces, but not edges and loops.
* Supports an optional id to element lookup table.
* Uses single id space for all elements
* Added a new CD_FLAG_ELEM_NOCOPY flag to tell
customdata_bmesh_copy_data to ignore that layer.
* IDs are stored as a temporary customdata layer with
CD_FLAG_ELEM_NOCOPY set.
* Got automasking to work with dyntopo properly.
- AutomaskingCache->factor
has been replaced with the new temp layer API (which works for all
PBVH modes).
- AutomaskingCache->factor is, however, only initialized for
topology and face set boundary modes (if DynTopo is enabled)
since it's probably better to calculate the rest dynamically
in that case.
* Fixed stats bug
* Got threaded mesh->bmesh conversion working (it's disabled
pending further testing however).
Note that SCULPT_dynamic_topology_enable_ex calls BKE_scene_graph_update_tagged,
which in tests was adding ~1 second to conversion time for larger
meshes. Do we need this call?
a new one from scratch, an operation that can be slow despite being
threaded.
PBVH building is a memory bound operation (not just on the CPU side
either, remember the draw buffers have to be fully regenerated too).
Incrementally updating it this way is enormously faster (about as fast
as non-dyntopo undo).
The downside is we don't have the convienience of users regularly
building the pbvh from scratch anymore. Dyntopo does try to
join empty PBVH nodes (which happens after every stroke), but
that's not a complete substitute for a decent tree balancer.
That's on the todo list.
* Wrote a new API for wrangling temporary customdata layers across pbvh types:
- SCULPT_temp_customlayer_ensure: makes sure a (named) customdata
layer exists. Works for multires; since these are temporary
layers we can safely allocate them in a temporary CustomData
structure (in ss->temp_vdata).
- SCULPT_temp_customlayer_get: initializes a special structure,
SculptCustomLayer, that is used to get per elem customdata.
- SCULPT_temp_cdata_get: Uses a SculptCustomLayer ref along with
a SculptVertexRef to look up the data.
* Sculpt code seems to be memory bandwidth bound.
* Some key topology loops will have to be written manually
instead of using BM_ITER.
I wrote a function to re-allocate a bmesh with elements ordered by
PBVH leaf nodes, SCULPT_reorder_bmesh. It's currently disabled.
This is going to take more profiling, but my original proxy refactor
idea might be worth revisiting. Might be more cache efficient.
The good news is that the worst case is the smooth code, which I can speed
up significantly by keeping a bit of state around.
* Sculpt expand now works with dyntopo in more cases
* Fixed various dyntopo face set bugs
Stuff from several commits ago:
* There is now an API to get face sets using SculptFaceRef's.
+ SCULPT_face_set_get
+ SCULPT_face_set_set
* Prototyped a faster geodesic propagation function, but it currently
doesn't work.
* Dyntopo triangulation now preserves face flags (took some work as BM_triangulate_face explicitly prevents selection flags from being preserved).
* Also face smooth flags are no longer being overriden.
* Most of the faceset create operators work (I'm not sure I've tested
all of them though).
* SCULPT_face_set.c now has helper functions that checks if a pbvh
is *not* PBVH_BMESH, in which case it builds a temporary bmesh,
otherwise ss->bm is used (sculpt_faceset_bm_begin and sculpt_faceset_bm_end).
+ Note that some functions were able to use SCULPT_face_set_XXX
instead and avoid bmesh entirely.
reference counted. This fixes various undo bugs caused by dyntopo
needing to execute an undo push but not being able too (e.g. during
file load, and I think it also happens sometimes with global undo).
A much better way of fixing this would be to add unique IDs to mesh
verts and faces, perhaps as a customdata layer.
The root problem is that BMLog assigns unique IDs to mesh elements,
which it does via a series of GHash's. I imagine this is a fairly
serious violation of the undo system's design rules, since it means
BMLogs are tied to specific instances of the bmesh in SculptSession->bm.
There were some hacks to try and get around this, but they were buggy
and needed to push the unstack stack to work, which wasn't possible in
all cases (e.g. if G_MAIN->wm.first->undo_stack is NULL, as it is during
file loading and apparently global undo).
Anyway, long story short each chain of SculptUndoNodes needs some way
to reconstruct their ID GHash's when exiting/entering the chain. The
only way I could think to do this was to make BMLog reference counted,
with BMLogEntry the users.
Like I said, having a proper system to assign unique IDs to mesh
elements would be *much* better.
things that need custom spacing (that is coaser than the brush radius),
and refactored the existing dyntopo spacing code to use it.
* Added option to topology rake to ignore brush falloff settings
(it forcibly uses Smooth falloff).
* Smooth and topology rake support custom spacing now.
+ This is especially important for the clay brush, which works
better at smaller spacings and with a bit of autosmoothing.
Now you can tell it to override the smooth spacing to be coarser,
leading to much better performance.
* Topology rake now has a projection setting similar to autosmooth
which defaults to 1.0 (to preserve current behavior).
The main motivation for this commit was to make topology rake work
better for normal brushes. This is now possible, however it tends to
make the brush slower and also the settings are a bit fiddly.
We might want to make dedicated brush presets for this.
Btw, the UI for brush settings are becoming a real mess. Help!
projection neighboring vertices onto the current smooth vert's normal
plane, multiplied by a "projection" factor. This is extremely similar
to what the surface laplacian produces, but is much simpler, uses
no temporary state and thus can be used in more places.
certain degenerate cases that produce lots of bad geometry (and
also bad PBVHs that slows down the whole mesh).
+ A very small amount of surface smoothing is now applied by dyntopo.
+ The recursive functions that expand the region considered by dyntopo
now ignore "front face only" for depths less then 5.
+ The number of edges dyntopo can split or collapse in one run has been cut in
half to 4k.
- This limit is also now dynamically adjusted by a measure
of how skinny the edges are.
- This required implementing SCULPT_UNDO_GEOMETRY for dyntopo.
That turned out to be more work then I expected. Basically
it writes an entire Mesh to BMLogEntry, which can be swapped
with current bmesh. Tricky part was patching bm log ids.
SCULPT_boundary_info_ensure, instead PBVH_BMESH keeps
track of boundary vert flags internally. This prevents
nasty first-click lag on the smooth brush as well as anything
with autosmooth.
Making multiply layers sequentially can lead to corrupted offsets.
Instead, ensure all layers exist with SCULPT_dyntopo_ensure_templayer
first,
then get all the offsets at once.
- To do this I made a little API to make scratch
customdata layers: SCULPT_dyntopo_[ensure/get]_templayer.
Takes a customdata type and a layer name (e.g.
'__dyntopo_bleh") and returns a customdata offset.
- Note that I also did this for the persistent base code.
* Added a macro to check if a tool supports splitting the PBVH
during a stroke, DYNTOPO_HAS_DYNAMIC_SPLIT. It is in sculpt_intern.h
(for now) to avoid the enormous amount of recompiling that is
triggered if DNA_brush_enum.h is modified.
* TODO: Right now the undo code resets original vertex coordinates for
bmesh PBVH. This means tools that rely on original data (sharp and
layer) can't split the pbvh during the stroke, since that will
allocate new undo nodes and reset original coords.
The solution is to move the original data API entirely out of the undo
code.
for DynTopo. Profiling consistently showed it to be a bottleneck.
I've now written scalar versions of this function four times.
For now I'm committing this inaccuration version. I'm also committing
code for a vectorized version I found in a paper. Still need to rejigger
the dyntopo code to use it though.
This system is designed to inherit settings from scene dyntopo defaults
in a highly flexible way; settings can be individually overridden via the
.inherit bitmask.
At stroke time the scene settings and brush->dyntopo are merged
and stored in brush->cached_dyntopo.
Note that brush->flag has a bit flag, DYNTOPO_DISABLED, with a few
subtlies. It does not switch the PBVH back to PBVH_FACES mode, it
simply disbles dyntopo topology update. It also doesn't inherit from
any default settings. And it's the only setting
that's currently exposed in the UI.
It stores:
- Original coordiates, colors and mask (which were previously four
seperate layers).
- A bitmask with (currently) one bitflag, whether or not a vertex is
on a boundary.
I needed to cache calculating vertex boundary state (which involves
iterating over the edges surrounding a vertex) and got fed up with
having so many CD layers for dyntopo. This struct consolidates them
and saves having yet another layer just to store a flag.
uniform triangle tesselations (dyntopo). This will be used for
a version of topological rake that aligns edge flows to lines of curvature
automatically.
Hopefully this will become a mask filter that can grow/shrink and smooth/
sharpen any mask shape interactively by dragging the pen, like the rest
of the filters.

Allow use all system threads for frame encoding/decoding. This is very
straightforward: the value of zero basically disables threading.
Change threading policy to slice when decoding frames. The reason for
this is because decoding happens frame-by-frame, so inter-frame threading
policy will not bring any speedup.
The change for threading policy to slice is less obvious and is based on
benchmark of the demo files from T78986. This gives best performance so

calculated as the second further intersecting triangle in the raycast
over the entire mesh. This information will also be used to improve and
create new tools.

When using Optimal Display, some edges are not flagged `ME_EDGEDRAW` |
`ME_EDGERENDER`.
When the modifier is applied through the UI in the modifier stack this is
not an issue because the `modifyMesh` callback is run with
`MOD_APPLY_TO_BASE_MESH` (this will effectively turn of Optimal
Display).
When converting to mesh though, this will just get an evaluated mesh
(where the edge flags are still the same as with the subdivision
modifier).
Now ensure every edge is flagged to draw after conversion.

This adds a Box option to the Text strip's style properties, plus related Box Margin value:
{F9208309}
When enabled the text is placed on top of a solid-filled rectangle of a chosen color, as shown below:
{F9208324}
When the box option is disabled the text strip works the same as it does now. When the box option is enabled the meaning of the Shadow option changes to provide a drop-shadow on the rectangle (and not on the text itself). The latter made more sense to me.
The box margin is specified as a fraction of the image width. The offset of the drop-down box shadow is fixed to a specific fraction of the image width as well.
I tested this feature on a movie of a couple of minutes containing dozens of text strips (all with box background), edge cases like multi-line strings and text overlapping the image edges.

Variables renaned:
- cfra -> timeline_frame
- nr -> frame index
- cfra_over -> overlap_frame
Function seq_give_stripelem_index was renamed to seq_give_frame_index.
Use bool return type where possible instead of int (the return values from fluid object are already boolean instead of int).
Also removed several if guards in API functions. If one of the arguments is in fact invalid / nullptr (should not happen though), it better to catch them directly where they failed and not silently escape them.
Refactor material assignment code such that:
- `build_mat_map()` just returns the built map (instead of relying on
modifying a map passed as parameter),
- `LISTBASE_FOREACH` is used to loop over a `ListBase` (instead of a
hand-crafted for-loop),
- just `return` when not enough material slots can be created (instead
of setting a boolean to false, then doing some useless work, then
checking the boolean),
- reorder some code for clarity, and
- rename `mat_map` to `matname_to_material` so that the semantics are
clearer.
No functional changes.
So a keyframed e.g. location slider would stay yellow/green even if its
corresponding channel was removed.
Needs a appropriate notifier so the listeners (e.g.
buttons_area_listener, view3d_buttons_region_listener) would cause a

This fix makes sure new files save `wmWindow.global_areas` under a different
name, so old Blender versions don't recognize and 0-initialize it.
Since enabling global area writing (ef4aa42ea4), loading a file in old
Blender versions would cause `wmWindow.global_areas` to be read, because there
was already reading code for it and `ScrAreaMap` was in SDNA.
However the `ScrArea.global` of the global areas would be NULL, because it was
*not* in SDNA (`ScrGlobalAreaData` was excluded).
Now, issue is that the code assumes that areas in the global area-map have a
valid ScrArea.global pointer.
Think this was a mistake in rB5f6c45498c92. We should have cleared all this data
on reading, until the global area writing was enabled.

When editbones were selected from the Outliner (and they were connected
to a parent) with the 'Sync Selection' option turned ON, they could not
get duplicated.
For duplication to work, the (connected) parent bone's tip also has to
be selected [which was not the case when selection is done from the
Outliner under above circumstances]. The reason being that
armature_duplicate_selected_exec ->
ED_armature_edit_sync_selection clears the BONE_ROOTSEL flag if the
parent bone's BONE_TIPSEL is not set.
Caused by rB71eb65328078 btw.
The correct "parent-tip-selection" would actually happen in activation
- `tree_element_active_ebone`
-- `tree_element_active_ebone__sel`
but for 'Sync Selection' this happens [also] in
- `outliner_sync_selection_from_outliner`
-- `outliner_select_sync_to_edit_bone`
which did not do the "flushing" to the parent bone's tip
Now use existing dedicated function for this.

Using configue_file(..) would have avoided the breakage from
1daa3c3f0a, caused by buildinfo not properly escaping quotes.
Rely on CMake to escaping strings instead using configure_file().
Use common prefix as this collided with existing API's (eg BLI_voronoi).
Also expand some non-obvious abbreviations:
- 'g' -> 'generic'
- 'vl' -> 'variable_lacunarity'
- 'V' -> 'v3'

"Camera Parent Lock" can be useful when rigging cameras, but it is not
intuitive, and has also generated a lot of confusion (bug reports).
This is because it breaks the fundamental parent <-> child relationship
conventions in Blender, and there is no indication that it's intended
without diving into the preferences.
This commit moves the setting to the object level, and exposes it in
the relations panel in the property editor. It is exposed for every
object type because any object type can be "View Locked" in the 3D view.
The property description is also updated to reflect this change and be
more specific without getting too long.
In the future this could become a more general feature of the transform
system, but for now it is limited to "Lock Camera to View".

- Handle sculpt color undo push nodes properly (shouldn't be hard).
NOTE: I've added a new function, DRW_make_cdlayer_attr_aliases, for

much of the usage of integer indices. Meshes and grids simply store the
index here, but bmesh stores a pointer to a BMVert. This greatly speeds
up DynTopo by reducing the need to maintain flat pointer arrays in bmesh.
To prevent the accidental casting of ScuptVertexRef to indices and vice
versa SculptVertRef is defined as a struct:
typedef struct {intptr_t i} SculptVertRef;
There are also two functions to convert flat index indices to
SculptVertRefs and back:
ScultpVertRef BKE_pbvh_table_index_to_vertex(PBVH *pbvh, int index);
int BKE_pbvh_vertex_index_to_table(PBVH *pbvh, SculptVertRef *ref);
Note that these functions require the aforementioned maintanance of
flat pointer arrays in bmesh, so make sure to call
SCULPT_ensure_vertex_random_access().
Changes:
* Brought back bmesh_mdisps_space_set, written from scratch using
subdiv api, not ccg.
* Wrote a function to smooth multigres grids from within bmesh. I might
not need it; unless anyone thinks of a use for it I'll go ahead and
delete it.
Todo:
* Purge code of all usages of CCG for multires.
This commit:
* Wrote a utility function to dump multires displacements into a (new)
scene object.
* Consequently, I now know that the CCG_based multires code is not
compatible with the OpenSubdiv based code. The former produces gaps
between grids when converting displacements to object space.
