A studio request actually.
The goal is to cover rather typical situation: when the mesh was
bound to target when the target was on subdivision level 0 but
uses a higher subdivision level for rendering. Example of such
setup is a facial hair bound to the face.
The idea of this change is to use first N vertices from the target
where N is the number of vertices on target during binding process.
While this sounds a bit arbitrary it covers typical modifier setup
used for rigging. Arguably, it is not more arbitrary than using a
number of polygons (which is how the modifier was checking for
changes on target before this change).
Quite straightforward change. A bit tricky part was to not break
the behavior since before this change we did not track number of
vertices sued when binding. The naming I'm also not super happy
with and just followed the existing one. Ideally the variables in
DNA will be prefixed with `target_` but doing it for an existing
field would mean compatibility change, and only using prefix for
the new field will introduce weird semantic where the polygons
count will be even more easily confused with a count on the
deforming mesh.

Make it explicit that counter is about target mesh.
Use DNA rename for it so that the files stay compatible.
Also renamed some purely runtime fields to replace `t`
prefix with `target` as the short `t` is super easy
to miss.

This adds support for X/Y/Z symmetry for all brushes in curves
sculpt mode. In theory this can be extended to support radial
symmetry, but that's not part of this patch.
It works by essentially applying a brush stroke multiple with
different transforms. This is similiar to how symmetry works in
mesh sculpt mode, but is quite different from how it worked in
the old hair system (there it tried to find matching hair strands
on both sides of the surface; if none was found, symmetry did
not work).

When height is limited, it is defined by space occupied by strips,
but at least channels 1 to 7 will be always visible. This allows it to
easily overview timeline content by zooming out to maximum extent in Y
axis and panning in X axis.
More channels can be "created" on demand by moving strip to higher
channel. When strip is removed and highest channel becomes empty, view
will stay as is until it is moved down. Then new highest point is
remembered and it is not possible to pan upwards until strip is moved to
higher channel.
Limiting takes into account height of scrubbing and markers area as
well as scrollers. This means that when zoomed out to maximum extent,
no strips are obstructed by fixed UI element.

The original mistake I made in b9febb54a4 was thinking
that the input curve object data to `BKE_displist_make_curveTypes`
was already copied from the original. I think I misread some of its
`ID` flags. This commit places the result of curves evaluation in a
duplicated curve instead, and copies the edit mode pointers
necessary for drawing overlays. `Curve` needs to know not to
free those pointers.
I still don't have a full understanding of why some of the tactics I've
used work and others don't. I've probably tried around 8 different
solutions at this point, and this is the best I came up with.
The dependency graph seems to have some handling of edit mode
pointers that make the edit mode overlays work if the evaluated
result is only an empty curve created by the evaluated geometry set.
This doesn't work with the current method and I need to set the
edit mode pointers at the end of evaluation explicitly.
We're constrained by the confusing duality of the old curves system
combined with the new design using the evaluated geometry set.
Older areas of Blender expect the evaluated `Curve` to be a copy
of the original, even if it was replaced by some arbitrary evaluated mesh.

The "PROP" in the name reflects its generic status, and removing
"LOOP" makes sense because it is no longer associated with just
mesh face corners. In general the goal is to remove extra semantic
meaning from the custom data types.
This adds support for rendering motion blur for volumes, using their
velocity field. This works for fluid simulations and imported VDB
volumes. For the latter, the name of the velocity field can be set per
volume object, with automatic detection of velocity fields that are
split into 3 scalar grids.
A new parameter is also added to scale velocity for more artistic control.
Like for Alembic and USD caches, a parameter to set the unit of time in
which the velocity vectors are expressed is also added. For Blender gas
simulations, the velocity unit should always be in seconds, so this is
only exposed for volume objects which may come from external OpenVDB
files.
These parameters are available under the `Render` panels for the fluid
domain and the volume object data properties respectively.

This patch contains an initial pixel extractor for PBVH and an initial paint brush implementation.
PBVH is an accelleration structure blender uses internally to speed up 3d painting operations.
At this moment it is extensively used by sculpt, vertex painting and weight painting.
For the 3d texturing brush we will be using the PBVH for texture painting.
Currently PBVH is organized to work on geometry (vertices, polygons and triangles).
For texture painting this should be extended it to use pixels.
{F12995467}
Screen recording has been done on a Mac Mini with a 6 core 3.3 GHZ Intel processor.
# Scope
This patch only contains an extending uv seams to fix uv seams. This is not actually we want, but was easy to add
to make the brush usable.
Pixels are places in the PBVH_Leaf nodes. We want to introduce a special node for pixels, but that will be done
in a separate patch to keep the code review small. This reduces the painting performance when using
low and medium poly assets.
In workbench textures aren't forced to be shown. For now use Material/Rendered view.
# Rasterization process
The rasterization process will generate the pixel information for a leaf node. In the future those
leaf nodes will be split up into multiple leaf nodes to increase the performance when there
isn't enough geometry. For this patch this was left out of scope.
In order to do so every polygon should be uniquely assigned to a leaf node.
For each leaf node
for each polygon
If polygon not assigned
assign polygon to node.
Polygons are to complicated to be used directly we have to split the polygons into triangles.
For each leaf node
for each polygon
extract triangles from polygon.
The list of triangles can be stored inside the leaf node. The list of polygons aren't needed anymore.
Each triangle has:
poly_index.
vert_indices
delta barycentric coordinate between x steps.
Each triangle is rasterized in rows. Sequential pixels (in uv space) are stored in a single structure.
image position
barycentric coordinate of the first pixel
number of pixels
triangle index inside the leaf node.
During the performed experiments we used a fairly simple rasterization process by
finding the UV bounds of an triangle and calculate the barycentric coordinates per
pixel inside the bounds. Even for complex models and huge images this process is
normally finished within 0.5 second. It could be that we want to change this algorithm
to reduce hickups when nodes are initialized during a stroke.

This commit removes all EEVEE specific code from the `gpu_shader_material*.glsl`
files. It defines a clear interface to evaluate the closure nodes leaving
more flexibility to the render engine.
Some of the long standing workaround are fixed:
- bump mapping support is no longer duplicating a lot of node and is instead
compiled into a function call.
- bump rewiring to Normal socket is no longer needed as we now use a global
`g_data.N` for that.
Closure sampling with upstread weight eval is now supported if the engine needs
it.
This also makes all the material GLSL sources use `GPUSource` for better
debugging experience. The `GPUFunction` parsing now happens in `GPUSource`
creation.
The whole `GPUCodegen` now uses the `ShaderCreateInfo` and is object type
agnostic. Is has also been rewritten in C++.
This patch changes a view behavior for EEVEE:
- Mix shader node factor imput is now clamped.
- Tangent Vector displacement behavior is now matching cycles.
- The chosen BSDF used for SSR might change.
- Hair shading may have very small changes on very large hairs when using hair
polygon stripes.
- ShaderToRGB node will remove any SSR and SSS form a shader.
- SSS radius input now is no longer a scaling factor but defines an average
radius. The SSS kernel "shape" (radii) are still defined by the socket default
values.
Appart from the listed changes no other regressions are expected.
This adds a new node editor overlay that helps users to see where
named attributes are used. This is important, because named
attributes can have name collisions between independent node

Add a new operator, "Start Tweaking Strip Actions (Full Stack)", which
allows you to insert keyframes and preserve the pose that you visually
keyed while upper strips are evaluating,
The old operator has been renamed from "Start Tweaking Strip Actions" to
"Start Tweaking Strip Actions (Lower Stack)" and remains the default for
the hotkey {key TAB}.
**Limitations, Keyframe Remapping Failure Cases**:
1. For *transitions* above the tweaked strip, keyframe remapping will
fail for channel values that are affected by the transition. A work
around is to tweak the active strip without evaluating the upper NLA
stack.
It's not supported because it's non-trivial and I couldn't figure it
out for all transition combinations of blend modes. In the future, it
would be nice if transitions (and metas) supported nested tracks
instead of using the left/right strips for the transitions. That
would allow the transitioned strips to overlap in time. It would also
allow N strips to be part of the (previously) left and right strips,
or perhaps even N strips being transitioned in sequence (similar to a
blend tree). Proper keyframe remapping through all that is currently
beyond my mathematical ability. And even if I could figure it out,
would it make sense to keyframe remap through a transition?
//This case is reported to the user for failed keyframe insertions.//
2. Full replace upper strip that contains the keyed channels.
//This case is reported to the user for failed keyframe insertions.//
3. When the same action clip occurs multiple times (colored Red to
denote it's a linked strip) and vertically overlaps the tweaked
strip, then the remapping will generally fail and is expected to
fail.
I don't plan on adding support for this case as it's also non-trivial
and (hopefully) not a common or expected use case so it shouldn't be
much of an issue to lack support here.
For anyone curious on the cases that would work, it works when the
linked strips aren't time-aligned and when we can insert a keyframe
into the tweaked strip without modifying the current frame output of
the other linked strips. Having all frames sampled and the strip
non-time aligned leads to a working case. But if all key handles are
AUTO, then it's likely to fail.
//This case is not reported to the user for failed keyframe
insertions.//
4. When using Quaternions and a small strip influence on the tweaked
Combine strip. This was an existing failure case before this patch
too but worth a mention in case it causes confusion. D10504 has an
example file with instructions.
//This case is not reported to the user for failed keyframe insertions. //
5. When an upper Replace strip with high influence and animator keys to

where Quaternion 180 degree rotation limitations prevent a solution.

of an off-by-one error calculating the particles `dietime`.
This value indicates the frame which the particle ceases to exist but

While the last frame was properly written and read from memory,
the `dietime` was set to the last frame causing all the particles to be

This patch adds color attributes to TexPaintSlot. This allows an easier selection

Previously when selecting a paint tool the user had to start a stroke, before the

This adds missing cases to detect edit mode for Curves objects.
Unlike other object types, Curves do not have specific edit data,
rather we edit the original data directly, and rely on `Object.mode`.
For this, `BKE_object_data_is_in_editmode` had to be modified to
take a pointer to the object. This affects two places: the outliner
and the dependency graph. For the former place, the object pointer
is readily available, and we can use it. For the latter, the object
pointer is not available, however since it is used to update edit
mode pointers, and since Curves do not have such data, we can
safely pass null to the function here.
This also fixes the assertion failure that happens when closing a file

Channel data is stored in `SeqTimelineChannel` which can be top-level

Strip properties are completely independent and channel properties are
applied on top of particular strip property, thus overriding it.
Implementation is separate from channel regions in other editors. This
