This revision contains the following changes-
- Updated the existing testing framework for Modifiers for Regression
Testing.
- Tests for Physics modifiers and remaining Generate and Deform modifiers are added.
- The existing `ModifierSpec` is updated with backward compatibility to support Physics Modifiers.
- Now there is support for frame number and giving nested parameters for attributes.
- Some Deform modifiers required Object Operators, e.g. "Bind" in Mesh Deform, so a new class was added to support that functionality.
- A separate class for holding Particles System, they are tested by converting all the particles to mesh and joining it to the mesh they were added.
- Updated the format to add tests for Bevel, Boolean and Operators as
well.

Currently, the random attribute node doesn't work well for most
workflows because for any change in the input data it outputs
completely different results.
This patch adds an implicit seed attribute input to the node, referred
to by "id". The attribute is hashed for each element using the CPPType
system's hash method, meaning the attribute can have any data type.
Supporting any data type is also important so any attribute can be
copied into the "id" attribute and used as a seed.
The "id" attribute is an example of a "reserved name" attribute,
meaning attributes with this name can be used implicitly by nodes like
the random attribute node. Although it makes it a bit more difficult
to dig deeper, using the name implicitly rather than exposing it as an
input should make the system more accessible and predictable.

Since a few versions (even before 2.79) we have an option that allows to restrict the vertex tools to operate only on deform groups. This was originally implemented for working with vertex groups for skeletal animation. In that case it is fortunate to have weight tools operate only on deforming vertext groups (vgroups assigned to bones)
In previous versions of Blender (up to 2.79) we have been able to use this option in Mesh Edit mode regardless of the armature mode. The current implementation (since 2.80 as far as i know) enables this option only when the associated armature is in pose mode. this has a bad consequence:
It is not at all intuitive that you have to put the armature into Pose mode before you can make use of the option in mesh edit mode.
Besides this it is not even necessary in the case when the user wants to restrict the tool only to all pose bones. In that case the armature can safely be kept in Object mode. However, when the tool shall apply only to selected pose bones, then it actually makes sense to have the armature in pose mode (as it is implemented right now)
I do not know why this feature has been restricted as described above. It must have got lost somewhere on the way to Blender 2.90
This patch fixes the issue as it allows to select the "restrict to pose bones" option when the armature is in any mode. I see no downsides of this change, actually this is a fix for a feature that once worked and apparently got forgotten in newer releases.

This tool implements smearing for multires displacement over the limit
surface, similar to how smearing for colors and topology slide works.
When used the displacement values of the vertices "slide" over the
topology, creating the effect of smearing the surface detail.
As the brush just modifies displacement values instead of coordinates,
the total displacement of the affected area doesn't change. This means
that this smearing effect can be used multiple times over the same area
without generating any artifacts in the topology.
When the brush is used with the pinch or expand smear modes,
displacement differences are pushed into the same area, creating hard
surface effects without pinching the topology.
As any other brush that relies on the limit surface (like displacement
erasers), this will work better after using apply base.

Casting pointers from one type to another does change the
value of the pointer in some cases. Therefore, casting a span
that contains pointers of one type to a span that contains
pointers of another type, is not generally safe. In practice, this
issue mainly comes up when dealing with classes that have a
vtable.
There are some special cases that are still allowed. For example,
adding const to the pointer does not change the address.
Also, casting to a void pointer is fine.
In cases where implicit conversion is disabled, but one is sure
that the cast is valid, an explicit call of `span.cast<NewType>()`
can be used.

It's useful to easily see which data-blocks are assets and which not. So just
like we usually show the library linking/override icons, we show the asset icon
there (these are mutually exclusive data-block states).
Uses the `'MAT_SPHERE_SKY` icon, which wasn't used before (except by an
add-on!) and is sorta fitting, but not quite. We should either change this one
or add an own asset icon. Meanwhile this isn't too bad :)
Also adds an internal macro to check if a data-block is an asset, consistent to
how we do it for libraries and library overrides.
This makes it possible to trigger a refresh of the data-block preview,
available next to the preview in the Asset Browser sidebar. The previews get
easily outdated and automatically refreshing it all the time is not an option
because it would be a consistently running, quite expensive process. So a
button to cause a refresh should be reasonable.
This button can also be used to switch back from a custom preview to a
generated one. Although that may not be clear, and we should probably think of
a way to explain that better.

* Move button to browse for a custom preview to the right of the preview, as

* Don't make the details panel a sub-panel. Looked weird because the parent

* Add info icon to "No asset selected", looks a bit friendlier.

If Preferences > Interface > Temporary Editors > File Browser is set to
"Maximized Area", opening a File Browser from a File or Asset Browser as
regular editor would cause some issues. For example after closing the
temporary File Browser, the regular browser would take over the file

used to share the same area data.
Some similar issues may have happend with temporary image editors.
Now, this commit finally separates the space data of temporary maximized
editors from the regular ones. So the editor data is entirely
independent now, as it should be.
This implements a mesh fairing algorithm and implements the fair
operations for Face Set edit. This edit operations create a smooth as
possible geometry patch in the area of the selected Face Set.
The mesh fairing algorithm is designed by Brett Fedack for the addon
"Mesh Fairing": https://github.com/fedackb/mesh-fairing, with some
modifications:
- The main fairing function in BKE_mesh_fair.h does not triangulate
the mesh. For the test I did in sculpt mode results are good enough
without triangulating the topology. Depending on the use and the
result quality needed for a particular tool, the mesh can be
triangulate in the affected area before starting fairing.
- Cotangents loop weights are not implemented yet. The idea is to
also expose the vertex and loop weights in a different function in
case a tool needs to set up custom weights.
This algorithm will also be used to solve the limitations of line
project and implement the Lasso Project and Polyline Project tools.
It can also be used in tools in other areas of Blender, like Edit Mode
or future retopology tools.

In this case, the operator gets the particle_system from (buttons)

The reason why none gets found here is that buttons_context() doesnt
have a valid path when called from F9/SCREEN_OT_redo_last, path is
cleared when global undo does a file-read which clears the path (see
lib_link_workspace_layout_restore). It can be recomputed though to be

Previews would be flagged as unfinished when reading. Instead clear the flag
and always consider them finished upon reading. If we wouldn't do this, the
File Browser would keep running the preview updating to wait for the preview to
finish. It could be smarter and also check if there's actually a preview job
running.
Instead, I think it will just display an unfilled buffer for now. Up until
today we wouldn't even know if a stored preview is finished or not, so it would
always assume they are finished. We do the same now, but have the option to
make it smarter.

One of the core design aspects of the Asset Browser is that users can "mount"
custom asset libraries via the Preferences. Currently an asset library is just
a directory with one or more .blend files in it. We could easily support a
single .blend file as asset library as well (rather than a directory). It's
just disabled currently.
Note that in earlier designs, asset libraries were called repositories.
Idea is simple: In Preferences > File Paths, you can create custom libraries,
by setting a name and selecting a path. The name is ensured to be unique. If
the name or path are empty, the Asset Browser will not show it in the list of
available asset libraries.
The library path is not checked for validity, the Asset Browser will allow
selecting invalid libraries, but show a message instead of the file list, to
help the user understand what's going on.

dragging needs to work with just the asset metadata, without direct access to
the data-block itself.
Idea is simple: When dragging an asset, store the source file-path and
data-block name and when dropping, append the data-block. It uses existing drop
operators, but the function to get the dropped data-block is replaced with one
that returns the local data-block, or, in case of an external asset, appends
the data-block first.
The drop operators need to be adjusted to use this new function that respects
assets. With this patch it only works for dragging assets into the 3D view.
Note that I expect this to be a short-lived change. A refactor like D4071 is
needed to make the drag & drop system more future proof for assets and other
use cases.

This makes it possible to turn data-blocks into assets and back into normal

Asset metadata is what turns a regular data-block into an asset. It is a small
data-structure, but a key part of the technical design of the asset system.
The design foresees that asset data-blocks store an `ID.asset_data` pointer of
type `AssetMetaData`. This data **must not** have dependencies on other
data-blocks or data-block data, it must be an independent unit. That way we can
read asset-metadata from .blends without reading anything else from the file.
The Asset Browser will use this metadata (together with the data-block name,
preview and file path) to represent assets in the file list.
Includes:
* New `ID.asset_data` for asset metadata.
* Asset tags, description and custom properties.
* BKE code to manage asset meta-data and asset tags.
* Code to read asset data from files, without reading IDs.
* RNA for asset metadata (including tags)

The geometry-nodes features no longer depend on the point cloud object.
Therefore the point cloud object, although important in the future, can
be postponed until we have render and edit mode fully working.
This reverts commits:
* ea74ed5a7a.
* dc614c68ef.
This implements the design proposed in T83357.
The goal is to allow the geometry nodes modifier on mesh objects to
output instances and potentially other geometry types. Both problems
are tackled by allowing mesh objects to evaluate to a geometry set,
instead of just a single mesh id data block. The geometry set can
contain a mesh but also other data like instances and a point cloud.
I can't say that I'm sure that this commit won't introduce bugs. Mainly
the temporary object creation during rendering seems a bit brittle.
BUT, we can be reasonably sure that this commit will not introduce
regressions (at least not ones, that are hard to fix). This is because
the code has been written in a way that minimizes changes for existing
functionality.
Given that we intend to hide the point cloud object for the next release,
we won't even have to worry about temporary object creation for now.
An important part of the technical design is to make sure that
`ObjectRuntime->data_eval` contains the same data before and after this
patch. This helps to make sure, that existing code paths are impacted as
little as possible.
Instead of fully replacing `data_eval`, there is `geometry_set_eval`,
which contains all the geometry components an object evaluated to
(including the data referenced by `data_eval`).
For now, not much code has to be aware of `geometry_set_eval`. Mainly
the depsgraph object iterator and the instances system have to know
about it.

This is just for convenience since it allows animators to keyframe
outside of the strip's bounds by default. This was likely off by
default before since Syncing Length would undesirably shift the whole
animation after leaving tweak mode (fixed by {D7602}) and the animator
wasn't able to keyframe outside the strip bounds anyways
(fixed by {D7533}). Now it's better if the flag was on by default.
While the animator is still roughly developing their animation NLA-wise
they won't have to worry about strip bound keying failures. When they
are more certain of the strip bounds, they can disable the flag to
prevent affecting the rest of the NLA system.

This changes the way how the mattes are stored in the compositor node. This used to
be a single string what was decoded/encoded when needed. The new data structure
stores all entries in `CryptomatteEntry` and is converted to the old `matte_id`
property on the fly.
This is done for some future changes in the workflow where a more structured
approach leads to less confusing and easier to read code.
Sometimes the geometry nodes modifier does support mapping and
sometimes it does not. We have no infrastruture to determine this ahead
of time currently. In order to support common use cases, it makes sense
to add this flag to the modifier.
One such common use case is to use the mesh as surface that other
things are distributed on. Often, the distribution is controlled by vertex
groups. Therefore, it would be helpful if the modifier is evaluated
when the object is in vertex paint mode. This allows the user to see the
distributed objects while painting.
If the nodes modifier transforms the mesh in any way, vertex painting
might not work as expected anymore, because the `deformMatrices`
callback is not implemented. I'm not sure how this can be solved nicely, yet.
Without this, the modifier evaluation code might remove any
vertex groups from the mesh for performance reasons.
We can't say for sure whether the node group will need the vertex
groups, but it is quite likely.

Object previews are really helpful for visual data-block selection, like asset
browsing. Having them be generative should also be quite handy and should work
well enough in many, if not most cases.
What this does is simple:
* Place the object (actually a deep copy of it, for thread safety) in a virtual
.blend into an empty scene/view-layer.
* Add a camera, point it towards the front of the object, assuming that means
pointing towards its +Y axis.
* Use "Camera Fit Frame to Selected" logic to put the object into frame.
* Create a threaded off-screen render.
Of course, such an automatic preview will not work in all situations. E.g. it
currently does a bad job capturing a single plane. We could add options for
more advanced automatic previews, but probably custom previews is more
important, which I committed already (812ea91842).

way smaller areas. This in turn causes Swing+Twist math to produce

If the destination layer hadn't keyframe, a new keyframe was added and later the merge layer strokes were added, but this could change the animation because the new frame replaced the old drawings of the target layer.
Now, before merge the layer, all keyframes are added in the target layer in order to keep the drawings.
This patch introduces a new BKE function that performs a uniform subdivide.
The goal of this function is to subdivide the stroke to reach a target number of points while maintaining its shape, color, and weights.
This is done by repeatedly subdividing the longest edge in the stroke. Every subdivision adds a new point at the exact middle point of an edge.
The function is intended to be used in the interpolation operators to give better results when interpolating between different sized strokes.

pass the data they represent to operators? We currently resort to ugly ad-hoc

to know that it is executed on a tab button that represents a data-block.
A single button can now hand operators a data-block to operate on. The operator
can request it via the "id" context member (`CTX_data_pointer_get_type(C, "id",
&RNA_ID)` in C, `bpy.context.id` in .py).
In this commit, it is already set in the following places:
* Generic RNA button code sets it to the pointed to data-block, if the button
represents a data-block RNA pointer property. (I.e for general data-block
search buttons.)
* Data-block selectors (`templateID`) set it to the currently active data-block.
* The material slot UI-List sets it for each slot to the material it represents.

The way the Outliner integrates operations on selected tree elements is known

unusual way and doesn't use the normal operator system. Instead, changes are

callbacks often implement logic that should not be in the Outliner, but in
entirely different modules. Often these modules already contain the logic, but
as proper operators.
This commit is a step into a hopefully better direction that should allow us to
put actual operators into Outliner context menus. It starts solving the problem
of: How can the Outliner pass selected data to operators. It implements it for

Idea is to keep doing what operators were initially designed to do: Operate on
context.
Operators can now query a "selected_ids" context member
(`CTX_data_selected_ids()` in C, `bpy.context.selected_ids` in .py). If an
Outliner is active, it will generate a list of selected data-blocks as a

wasn't freed.
BLI_str_quoted_substrN didn't unescape the resulting string,
yet all callers were using this with animation paths which are
created using BLI_str_escape().
- Fix BLI_str_quoted_substrN use with escaped strings by calling
BLI_str_unescape().
Note that it's possible we want an a version of this function that
keeps escape characters. This could be added if it's required.
- Fix end quote detection using BLI_str_escape_find_quote
checking for `\"` isn't reliable since an even number of back-slashes
before a quote means it's not escaped.
The issue is caused by stale data on the Mesh Node which is not cleared
during synchronizing since the socket API refactor so that we can detect
changes. However, synchronization only updates the sockets of the Mesh,
so other properties were left with outdated values.
This caused an underflow when computing attribute size for undisplaced
coordinates as it was using the current number of vertices minus the
previous count of subdivision vertices, which at this point should be 0.
Added a simple method to clear non socket data. Also modified
Mesh.add_undisplaced to always use an ATTR_PRIM_GEOMETRY as the data is
not subdivided yet and it avoids any further issues regarding computing
attribute sizes.
This adds deformation types to snake hook and the elastic deformation
type. This mode deforms the mesh using a kelvinlet instead of applying
the displacement directly inside the brush radius, which is great for
stylized shapes sketching.
Changes in rake rotation when using elastic are too strong when set
to 1, so I'll add a nicer way to support rake rotations with smoother
transitions in the future.

* Avoid direct access to `SpaceFile.params`, use a getter instead. This matters
because once the asset-browser changes are in, there will be an alternative

* Rename the function to ensure the parameters. The old name
`ED_fileselect_get_params()` wasn't a mere getter, it would create the

* In some instances, I replaced the old "get" function with the new mere

should be able to assume the selection parameters were created already as

Fix the Assign Automatic Weights operator in weight paint mode when the

either `me->editflag & ME_EDIT_VERTEX_GROUPS_X_SYMMETRY` or
`me->symmetry & ME_SYMMETRY_X`. In this case, the former wasn't working,
so I replaced it with the latter.
Continuation of the work started with 249e4df110. After all display modes
were ported to this new design, this commit starts the (more complex) work on
the individual tree-element types. More concretely it ports animation
tree-elements (action data-blocks, drivers and NLA data).
The commit above explains motivations. In short, we need a better design that's
easier to reason about and better testable.
Changes done here are pretty straight forward and introduce similar class
hierarchy and building patterns as introduced for the display modes already.
I.e. an abstract base class, `AbstractTreeElement` with derived classes for the
concrete types, and a C-API with a switch to create the needed objects from a
type enum. The latter should be replacable with something nicer later on (RAII
based, and type-safer through meta-programming).
Each tree-element type has its own class, with an own header and source file
(okay some closely related types can share a header and source file, like the
NLA ones).
I added some further temporary bits for the transition to the new design, such
as the `TreeElement.type`. It should entirely replace `TreeElement` eventually,
just as `outliner_add_element()` should be quite small by then and easily
replacable by a `TreeBuilder` helper.
Mistake in 35a5dee2ef.
Code would simply assume that the element under the cursor is an Object if it
was an ID (but not a collection).
This wouldn't cause any issues in current code, since the only other ID that
set the direct-data were collections, which are special in that they don't have
a `TreeStoreElem.type` of 0, which is already being checked for here. And if
there was no direct-data set, the object lookup in the View-Layer would
correctly fail too.
I carefully checked and am quite sure for `TSE_ANIMATION_DATA` and
`TSE_NLA_ACTION` the direct-data isn't used at all. This data is stored and
accessed in unsafe ways based on conventions anyway (`void *`). We should aim
for a safer design but it will be difficult to get there. Any removed
complexity will help.
Non-ID tree-elements would cast their data pointer to `ID *` and take the name
and ID-Code from there. The name would actually be overridden a few lines
later, so that didn't cause issues. But the ID-Code stored inside the tree
element kept an undefined value. In practice that probably didn't cause many
issues either, since it's just an undefined value that was very unlikely to
take a valid 16-bit ID-code value, meaning ID-Code checks would simply fail as
they should. Further there typically are other checks to see if the element
actually represents an ID.
However, in theory this may have caused a few random crashes or
data-corruptions.
Modernize loops by using the `for(type variable : container)` syntax.
Some loops were trivial to fix, whereas others required more attention
to avoid semantic changes. I couldn't address all old-style loops, so
this commit doesn't enable the `modernize-loop-convert` rule.
Although Clang-Tidy's auto-fixer prefers to use `auto` for the loop
variable declaration, I made as many declarations as possible explicit.
To me this increases local readability, as you don't need to fully
understand the container in order to understand the loop variable type.

Cryptomatte is a standard to efficiently create mattes for compositing. The
renderer outputs the required render passes, which can then be used in the
compositor to create masks for specified objects. Unlike the Material and Object
Index passes, the objects to isolate are selected in compositing, and mattes
will be anti-aliased.
Cryptomatte was already available in Cycles this patch adds it to the EEVEE
render engine. Original specification can be found at
https://raw.githubusercontent.com/Psyop/Cryptomatte/master/specification/IDmattes_poster.pdf
**Accurate mode**
Following Cycles, there are two accuracy modes. The difference between the two
modes is the number of render samples they take into account to create the
render passes. When accurate mode is off the number of levels is used. When
accuracy mode is active, the number of render samples is used.
**Deviation from standard**
Cryptomatte specification is based on a path trace approach where samples and
coverage are calculated at the same time. In EEVEE a sample is an exact match on
top of a prepared depth buffer. Coverage is at that moment always 1. By sampling
multiple times the number of surface hits decides the actual surface coverage
for a matte per pixel.
**Implementation Overview**
When drawing to the cryptomatte GPU buffer the depth of the fragment is matched
to the active depth buffer. The hashes of each cryptomatte layer is written in
the GPU buffer. The exact layout depends on the active cryptomatte layers. The
GPU buffer is downloaded and integrated into an accumulation buffer (stored in
CPU RAM).
The accumulation buffer stores the hashes + weights for a number of levels,
layers per pixel. When a hash already exists the weight will be increased. When
the hash doesn't exists it will be added to the buffer.
After all the samples have been calculated the accumulation buffer is processed.
During this phase the total pixel weights of each layer is mapped to be in a
range between 0 and 1. The hashes are also sorted (highest weight first).
Blender Kernel now has a `BKE_cryptomatte` header that access to common
functions for cryptomatte. This will in the future be used by the API.

This patch adds support for AOVs in EEVEE. AOV Outputs can be defined in the
render pass tab and used in shader materials. Both Object and World based
shaders are supported. The AOV can be previewed in the viewport using the
renderpass selector in the shading popover.
AOV names that conflict with other AOVs are automatically corrected. AOV
conflicts with render passes get a warning icon. The reason behind this is that
changing render engines/passes can change the conflict, but you might not notice
it. Changing this automatically would also make the materials incorrect, so best
to leave this to the user.
**Implementation**
The patch adds a copies the AOV structures of Cycles into Blender. The goal is
that the Cycles will use Blenders AOV defintions. In the Blender kernel
(`layer.c`) the logic of these structures are implemented.
The GLSL shader of any GPUMaterial can hold multiple outputs (the main output
and the AOV outputs) based on the renderPassUBO the right output is selected.
This selection uses an hash that encodes the AOV structure. The full AOV needed
to be encoded when actually drawing the material pass as the AOV type changes
the behavior of the AOV. This isn't known yet when the GLSL is compiled.
**Future Developments**
* The AOV definitions in the render layer panel isn't shared with Cycles.
Cycles should be migrated to use the same viewlayer aovs. During a previous
attempt this failed as the AOV validation in cycles and in Blender have
implementation differences what made it crash when an aov name was invalid.
This could be fixed by extending the external render engine API.
* Add support to Cycles to render AOVs in the 3d viewport.
* Use a drop down list for selecting AOVs in the AOV Output node.
* Give user feedback when multiple AOV output nodes with the same AOV name

This change solves a bottleneck which was caused by attempt to cache
postprocessed search areas used for tracking. It was a single cache
used by all threads, which required to have some synchronization
mechanism. This synchronization turned out to be making all threads
to idle while one thread is accessing the cache. The access was not
cheap, so the multi-threading did not provide expected speedup.
Current solution is to remove the cache of search areas. This avoids
any threading synchronization overhead because there is no need for
it anymore. The downside is that for certain configurations tracking
became slower when comparing to master branch. There is no expected
slowdown compared to 2.91 release.
The slowdown is mainly experienced when using big search area and
keyframe matching strategy. Other cases should still be within a
ballpark of performance of single-threaded code prior to this change.
The reason why is it so is because while this change makes it so the
image accessors needs to process images multiple times the complexity
of this process is almost the same as all the overhead for the cache
lookup and maintenance.

up red, the color for "input" nodes. This patch introduces two new
colors, one for "Geometry" and one for "Attributes". There are only two
attribute nodes currently, but the next sprint will add two more,
attribute mix, and sample from texture. The attribute nodes are
conceptually different enough from the nodes that modify the geometry
that they deserve their own color.

Until there is a icon made specially for this, the nodetree icon is up
for grabs. Using it in the nodegroup + modifier + editor helps the users
to make a connection on where to edit those modifiers.
The point cloud object is the only one that will support instancing at
first. So we can expose it as a regular object.
It is limited since it has no edit mode. But this is not different than
the volume object.
This commit adds functions to set and get the object's active
modifier, which is stored as a flag in the ModifierData struct,
similar to constraints. This will be used to set the context in
the node editor. There are no visible changes in this commit.
Similar to how the node editor context works for materials, this commit
makes the node group displayed in the node editor depend on the active
object and its active modifier. To keep the node group from changing,
just pin the node group in the header.
* Shortcuts performed while there is an active modifier will affect
only that modifier (the exception is the A to expand the modifiers).
* Clicking anywhere on the empty space in a modifier's panel will make it active.
These changes require some refactoring of object modifier code. First
is splitting up the modifier property invoke callback, which now needs
to be able to get the active modifier separately from the hovered
modifier for the different operators.
Second is a change to removing modifiers, where there is now a separate
function to remove a modifier from an object's list, in order to handle
changing the active.
Finally, the panel handler needs a small tweak so that this "click in panel"
event can be handled afterwards.
The handling of muted nodes is handled at the derived node tree
level now. This is also where expanding node groups is handled.
Muted nodes are relinked and removed from the derived tree
during construction. The geometry node evaluation code does
not have to know about muted nodes this way.
Objects can evaluate to a geometry set instead of a single ID (only point cloud
objects for now). In the depsgraph object iterator, the evaluated geometry
components are expanded into temporary objects.
It's important to note that instanced objects can also contain geometry
components. Therefore, they have to be split up into multiple objects
as well in some cases.
At a high level the iterator works like so:
```
for object in depsgraph:
for component in object:
yield object_from_component(component)
for dupli in make_duplis_list(object):
for component in dupli:
yield object_from_component(component)
```
DEG_iterator_objects_next has been cleaned up, to make this structure
a bit more apparent.
This should not change anything for objects that are not point clouds.
This is the initial merge from the geometry-nodes branch.
Nodes:
* Attribute Math
* Boolean
* Edge Split
* Float Compare
* Object Info
* Point Distribute
* Point Instance
* Random Attribute
* Random Float
* Subdivision Surface
* Transform
* Triangulate
It includes the initial evaluation of geometry node groups in the Geometry Nodes modifier.
Notes on the Generic attribute access API
The API adds an indirection for attribute access. That has the following benefits:
* Most code does not have to care about how an attribute is stored internally.
This is mainly necessary, because we have to deal with "legacy" attributes
such as vertex weights and attributes that are embedded into other structs
such as vertex positions.
* When reading from an attribute, we generally don't care what domain the
attribute is stored on. So we want to abstract away the interpolation that
that adapts attributes from one domain to another domain (this is not
actually implemented yet).
Other possible improvements for later iterations include:
* Actually implement interpolation between domains.
* Don't use inheritance for the different attribute types. A single class for read
access and one for write access might be enough, because we know all the ways
in which attributes are stored internally. We don't want more different internal
structures in the future. On the contrary, ideally we can consolidate the different
storage formats in the future to reduce the need for this indirection.
* Remove the need for heap allocations when creating attribute accessors.

* Dalai Felinto
* Hans Goudey
* Jacques Lucke
* Léo Depoix

The object are not properly mirrored in object mode.
For mirroring an object that has an arbitrary rotation along the X axis
this is the procedure:
1. mirror x location.
2. negate x scale of the
3. negate y and z component of the rotation (independent of which rotation mode is used).
This knowledge applies now for all angles and axes to finally make the
mirror operation work in object mode.
The new mirror function has the downside that it can not (in this form)
be used with proportional editing.
This is no problem since the old behavior can still be replicated by
scaling with -1 along any axis.
The solution to get perfect mirrors can not work for scaling in general,
because in that case there could be scew created.

The idea is to avoid any synchronization needed in the worker threads
and make them to operate on a local data. From implementation detail
this is achieved by keeping track of "wavefront" of markers which are
to be tracked and the tracking result. Insertion of results to the
AutoTrack context happens from main thread, which avoids need in the
lock when accessing AutoTrack.
This change makes tracking of many (300+) about 10% faster on the
Xeon) CPU E5-2699 v4. More speedup will be gained by minimizing
threading overhead in the frame cache.
Another important aspect of this change is that it fixes non-thread
safe access which was often causing crashes. Quite surprising the
crash was never reported.
Log to verbosity level 1 rather than INFO severity.
Avoids a lot of overhead coming from construction of the INFO stream

Makes it more clear whether object is allowed or not allowed to be NULL.
Also, avoids possible access to the different object mode enumerator.

During revision of {D8952} one of the comments was to make a function that converts the render percentage to a factor. This to avoid code duplication. However the duplicated code was already all over the compositor code. So in order to avoid this code duplication for {D8952} I propose to first cleanup the duplicated code and build patch {D8952} based on this clean up.
The method that converts the render percentage to a factor is put in the CompositorContext. Why? The CompositorContext keeps DNA information like the renderdata. DNA, and thus the CompositorContext, keeps the size of the render resolution in percentage (user oriented). The compositor needs the size of the render resolution as a factor. So the CompositorContext seems like the obvious place to have this conversion method.
Why not in de NodeBase? The method could've been added to the nodebase, but I wanted to keep the nodebase as clean as possible and not put simple "conversion" methods into this base class. Also I didn't really like the call flow: you'd always have to get the renderdata size from the context and then convert.
Putting it in the CompositorContext avoids this extra invoke of a call.
Why not in the Converter? See nodebase. And the Converter seems more like a class for "structural" and complex node tree conversions. Not the simple conversions.

By checking if a cell has already been processed in the finding patch

In case where there are coplanar instersections where

merges smaller patch-sixe cells into larger ones.
All this reduces the time to find cells in the cited case by a factor of 10.

While this works well, it can be cumbersome and slow.

This patch implements a solution where these "special" attributes are

The panel title text intersected any buttons in the header because
the label offset retrieved from the layout code was not scaled by

The transform modifiers are confirmed by releasing any button.
Thus, the operation can be falsely confirmed if the button that launched
the operation is released after the modifier has been activated.
Previously the events that confirmed the modifiers were hardcoded.
An option to fix this would be to add custom confirmation keyitens for
specific modifiers. But this can be a bit confusing and would make the
modal keymap even bigger.
So the solution here is to skip the button that launched the operation
when confirming the modifier.
Material indices and smooth states are not destroyed anymore.
If the two incoming meshes use different materials, the materials of

Orthogonalize the constraint target's matrix before decomposing it into

- With the sparse optimization grid cells with a value under the 'Empty Space' value (already present in domain settings) will not be cached.
- The main benefits of this optimization are: Smaller cache sizes and faster playback of simulation data in the viewport.
- This optimization works 'out-of-the-box'. There is no option in the UI to enable it.

- The node editor's node group always updates, even when there is no

- Pinning disables the drop-down and keeps the same node group

This is designed to work similarly to materials and material slots,

This change will use the image engine to draw the backdrop of the compositor. With this patch the alpha blending will be done in Linear Scene Reference space and shows pure emissive colors.
See differential for an example image.
**Technical changes**
As only the backdrop drawing is done using the draw manager there are some technical changes.
1. The overlay buffer is partly drawn outside the draw manager. When drawing the backdrop image the overlay buffer needs to be masked to simulate premultiplied alpha under.
2. The backdrop of the node editor is done in region pixel space. A `DRWView` is constructed with this space.
3. UDIM textures uses world position to generate the UV coordinates. This has been implemented more strict by the `IMAGE_DRAW_FLAG_USE_WORLD_POS`. When the flag isn't used the local coordinates are used to generate the UV coordinates what is image space.
4. The draw manager now checks the actual `eSpaceType` of the space data to use different code paths. In the future the movie clip editor will be added.
NOTE: The preview images in nodes are drawn in display space and cannot show pure emissive colors. As preview images are used on more locations it is best to fix this in a separate patch.

According to feedback the outliner to properties editor tab switching
was annoying when it always changed tabs on selection, especially for
selecting individual objects. This limits the tab switching behavior to
only when the icons in the outliner are selected.
This commit includes these improvements to operators and how they
relate to the active modifier:
- Shortcuts performed while there is an active modifier will affect
only that modifier.
- Clicking anywhere on the empty space in a modifier's panel will make
it active.
- Clicking anywhere in the empty properties space will clear the
active.
These changes require some refactoring of object modifier code. First
is splitting up the modifier property invoke callback, which now needs
to be able to get the active modifier separately from the hovered
modifier for the different operators. Second is a change to removing
modifiers, where there is now a separate function to remove a modifier
from an object's list, in order to handle changing the active. Finally
the panel handler neeeds a small tweak so that this "click in panel"
event can be handled afterwards.
Adds smooth scrolling with the trackpad for popovers. Also fixes the position of the scroll arrows on high-DPI.

This new discontinuity filter performs actions on the entire Euler

The filter now runs twice on the selected channels, in this order:
- New: Convert X+Y+Z rotation to matrix, then back to Euler angles.
- Old: Add/remove factors of 360° to minimize jumps.
The messaging is streamlined; it now reports how many channels were
filtered, and only warns (instead of errors) when there was an actual
problem with the selected channels (like selecting three or more
channels, but without X/Y/Z triplet).

Similar to how the node editor context works for materials, this commit
makes the node group displayed in the node editor depend on the active

just pin the node group in the header.
There are still missing updates when switching the modifier's node group.
This exposes the operator to set the active modifier as the type icon
in the header of the modifier panels. Tweaks to the widget drawing
code were necessary to use the red alert for non-emboss operator

(which currently uses the property search theme color), requiring
an "active property" field in the PanelType struct.
Previously, it was always outputting an empty geometry in that case.

Cover all atomic functions with unit tests.
The tests are quite simple, nothing special so far. The goal is to:
- Make sure implementation exists.
- Implementation behaves the same way on all platforms
(We had issue when MSVC and GCC were behaving differently in the

- Proper bitness is used for implementation and non-fixed-size

The tests can be extended further to make sure, for example, that
CAS operations do not cast arguments to a more narrow type for
comparison. Considering it a possible further improvement, as it is
better be done being focused on that specific task.
There is an annoying ifdef around 64bit implementation, which uses
same internal ifdef as the header does. This check is aimed to be

The tests seems somewhat duplicate for signed/unsigned variants and

as possible: attempting to do something smart/tricky in the test code
often causes the test code to be a subject of being covered with its

Previously the lock-free tests were actually testing guarded allocator

There seems to be no allocations happening between the initialization

The test are passing locally, so the "should work" has high chance

Previously the only way to use lockfree implementation was to start

Surely, it is not possible to switch implementation once any allocation

Some DNA headers already did this, most did not. Even though many of them would

However, this is a misconception.
`extern "C"` does not cause code to be compiled with C rather than C++! It only
causes the linker to not use C++ function name mangling. See
https://stackoverflow.com/a/1041880.
Because extern DNA headers don't have function declarations, using `extern "C"`

This option joins any stroke with an end near the actual stroke. Now it is not limited to the last stroke, any stroke in the same layer for the actual frame can be joined. The join can join two strokes drawing a third stroke.
If the end and the start of the result stroke are very small, the stroke is changed to be cyclic automatically.
There is a limit distance to join the stroke, if the distance is greater than this value, the strokes are not joined. Actually, a constant, threshold distance is used, but we could expose
as a parameter in the UI in the future.

Note, while the implementation can already randomize attributes, it might

The root cause of this bug is that the function that updates the PBVH
normals is drw_sculpt_generate_calls. As now both the overlays and
mesh can be drawn without using pbvh drawing, the normals were not
updating. This patch forces a normals updates also in the no PBVH
drawing code path of the overlays. This was affecting both shading and
sculpt surface sampling in both flat and smooth shading modes.
Having the sculpt normals being updated by the drawing code is a wrong
design which also causes other issues like:
Brushes that sample the surface and do multiple stroke steps between
redraws will sample invalid normals, creating artifacts during the
stroke clearly visible in some brushes.
Brushes that do not need to sample the surface update the normals on
each redraw. This affects performance a lot as in some cases, updating the
normals takes more time than doing the brush deformation. If flat shading
is being used, this is only necessary to do once after the stroke ends.

I will have to do a couple more iterations on this api in the upcoming weeks,
but for now it should be good enough.
The API adds an indirection for attribute access. That has the following benefits:
* Most code does not have to care about how an attribute is stored internally.
This is mainly necessary, because we have to deal with "legacy" attributes
such as vertex weights and attributes that are embedded into other structs
such as vertex positions.
* When reading from an attribute, we generally don't care what domain the
attribute is stored on. So we want to abstract away the interpolation that
that adapts attributes from one domain to another domain (this is not
actually implemented yet).
Accessing attributes through this indirection does have a performance penalty.
In later iterations of this API I want to reduce this penalty and extend the API
so that performance critical code does not have to go through the indirection
for every attribute access.
Other possible improvements for later iterations include:
* Actually implement interpolation between domains.
* Don't use inheritance for the different attribute types. A single class for read
access and one for write access might be enough, because we know all the ways
in which attributes are stored internally. We don't want more different internal
structures in the future. On the contrary, ideally we can consolidate the different
storage formats in the future to reduce the need for this indirection.
* Remove the need for heap allocations when creating attribute accessors.

from D9158 didn't consider the case where the collection could no longer
be found in its original view layer (moving a collections betwen scenes).
The fix is to just check if the collection starts in the same scene as
it will be moved to before trying to do the flag syncing. I thought about
this for a while and tried a couple other solutions, but I couldn't come
up with a proper way to support syncing the layer collection flags across
scenes without making too many changes.

Root of the issue is that point caches are added to the object's list
on-demand, which often ends up with them being added only during
depsgraph evaluation, i.e. on COW objects.
This could result in having 'orig' data caches with invalid/unset stack
index at some points (e.g. when reading a file and applying
liboverrides), leading to discarding valid existing disk cache files.
Fact that one of those index is signed, and the other not, does not
help...
While this is very weak, fixing broken PointCache code is out of the
scope of a bug fix, so this patch merely:
* Simplifies and factorizes the code generating the 'extension' part of
caches filenames;
* Ensures `BKE_object_insert_ptcache` is called when needed so that we
always have a valid stack index to generate that filename extension.
This is only a bandaid, but it is simple and should be safe enough for
now.

'updateGLSLCurveMapping()' compares cacheIDs and in certain scenarios,
these are the same when they should not.
- whenever we had multiple viewports that are colormanaged with
curvemappings this worked right (cacheIDs were different)
- for example, this also worked right when the ImageEditor displays a
Render Result or a Compositor Viewer
- but it worked wrong when the Image Editor displays any other Image (or
no Image at all)
- it also worked right if there were multiple Image Editors [and one of
them displays a Render Result e.g]
Now why is this so?
For comparison, the curve mapping's pointer/address is used.
- update_glsl_display_processor frees the curve_mapping, see
BKE_curvemapping_free(global_glsl_state.curve_mapping)
- similar, update_glsl_display_processor creates a new curvemapping, see
BKE_curvemapping_copy(view_settings->curve_mapping)
- now for the situation that a viewport with curvemapping and a viewport
without curvemapping is present and you make changes to the curvemapping
the following happens:
-- curve_mapping_settings->cache_id is set once [to the memory address
of curvemapping before change]
-- change happens
-- viewport 1 frees curvemapping
-- viewport 2 duplicates using BKE_curvemapping_copy, but this one gets
the same address like before the change
-- this means we have different data on the same address with the same
cacheID...
Solution: to really make the cache ID unique we can combine the pointer
with its 'changed_timestamp' [which increases on every change].

This is a technical limitation that will resolved a bit later.
Objects can evaluate to a geometry set instead of a single ID (only point cloud
objects for now). In the depsgraph object iterator, those geometry components
are expanded into temporary objects.
It's important to note that instanced objects can also contain geometry
components. Therefore, they have to be split up into multiple objects
as well in some cases.
At a high level the iterator works like so:
```
for object in depsgraph:
for component in object:
yield object_from_component(component)
for dupli in make_duplis_list(object):
for component in dupli:
yield object_from_component(component)
```
DEG_iterator_objects_next has been cleaned up, to make this structure

This changes the signature of the modifyPointCloud function.
I'm doing that instead of making a new callback, because it requires
changes to significantly fewer files. Eventually it would be good
combine modifyMesh, modifyHair, modifyPointCloud and modifyVolume
into one modifyGeometrySet.
I temporarily disabled the displacement only modifiers for point clouds.
Support can be added back a bit later. I assume those have not been
used anywhere anyway.
The output of point cloud modifiers can not only be another point cloud,
but also a mesh and/or some instances. I added a new geometry_set_eval
field to Object_Runtime. For point cloud objects, the final geometry is
now referenced by that pointer instead of data_eval. The data_eval field
is still initialized after modifier evaluation to make some other code happy.
The evaluated geometry set is not yet passed to the renderer, so a point
cloud is currently rendered empty.
This caused warnings when e.g. building the lite profile because NanoVDB was not disabled, but
OpenVDB was. This Fixes this by setting the "WITH_NANOVDB" flag too.
This node takes an object as input and outputs its location, rotation,
scale and geometry. Right now the loc/rot/scale are extracted from the
objects `obmat`. The geometry is just the mesh in the local space of the
source object.
We will likely need some more control over space transformations
using enums in the node, but those can be added a bit later.
The fundamental difference between object sockets and the
other existing data sockets is that an object is an ID data block.
Changing the value of an object socket also changes the depsgraph.
The modifier has to analyse the node tree to figure out which other
objects it depends on. Currently, this is done very simply by just
looping over all sockets and collecting the objects. In the future
this can be improved by also figuring out what components of
an object are needed.
Instead of passing object pointers around in the node tree, we actually
use a handle. This handle is just a number internally that identifies
a specific object. The conversion between handles and object pointers
is done using a map that is provided by the modifier.
This approach has a couple of benefits. It protects us a bit from passing
around pointers that are not known to the modifier and therefore are
not in the depsgraph. Furthermore, the object pointer can change
while the handle stays the same. This is not important right now, but
is not unlikely to become useful in the future.
The API for how nodes access object pointers is not ideal yet and
will be improved in the future.
Add a new property `co_ui` to Keyframes, the modification of which will

That way, when we go back and undo to the memfile, said IDs are properly

Otherwise, undo system sees them as unchanged, and just re-use the

----
Motivation
General problems with current design:
* The Outliner tree building code is messy and hard to follow.
* Hard-coded display mode checks are scattered over many places.
* Data is passed around in rather unsafe ways (e.g. lots of `void *`).
* There are no individually testable units.
* Data-structure use is inefficient.
The current Outliner code needs quite some untangling, the tree building seems
like a good place to start. This and the followup commits tackle that.
----
Design Idea
Idea is to have an abstract base class (`AbstractTreeDisplay`), and then
sub-classes with the implementation for each display type (e.g.
`TreeDisplayViewLayer`, `TreeDisplayDataAPI`, etc). The tree-display is kept
alive until tree-rebuild as runtime data of the space, so that further queries
based on the display type can be executed (e.g. "does the display support
selection syncing?", "does it support restriction toggle columns?", etc.).
New files are in a new `space_outliner/tree` sub-directory.
With the new design, display modes become proper units, making them more
maintainable, safer and testable. It should also be easier now to add new
display modes.
This should not change any functionality.
After talking to Brecht, we agreed that it might be good
not to have a class called Geometry for now. In the future
we might want to use a Geometry class as base class for
meshes, curves, etc.
This commit renames the Geometry class to GeometrySet,
because it is essentially a container that can contain
multiple geometries of different types.
This node is similar to the subdivision surface modifier. It subdivides
the mesh component of a geometry. The options have the same meaning
as in the modifier.
Differential Revision: https://developer.blender.org/D9364
Naming based on supported geometry components only works in some cases.
For nodes that work with multiple data types, it's better to categorize
them based on their functionality.
Theoretically the modifier's properties could be changed or removed by
Python, so it may be useful to have errors printed and added to the
modifier in that case.
I kept the check as a separate step from the `compute_geometry`
pass because the object is needed to set the modifier error message.
But it could easily be moved there in the future.
If we add the "name" label manually with uiItemR, we can use the socket
identifier instead of the name for the IDProperty name. This will also
allow us more flexibility in how to draw the settings in the future, and
removes the empty _RNA_UI proprety that was drawn before.
The system for exposing property settings like min, max, default, subtype,
etc. for ID properties is quite convoluted currently, so I won't give a
full description here, but this commit creates the tree of ID properties
needed to store that information. This means that property subtypes like
"angle" or "XYZ" will affect the display in the modifier.
Limitations:
- The _RNA_UI property is displayed in the modifier. This may require a
modification to uiDefAutoButsRNA to fix.
- IDProperties must have unique names, but node sockets don't have
that limitation. This can be solved by adding a "UI name" field to
IDProperties.
We can't use that for now, because the original mesh might be freed
before the new copied mesh. When the original mesh is freed, the shared
layers will be freed as well.
This can probably be improved in the future, so that we can actually
share attribute arrays between meshes. An approach similar to how
geometries and components are shared should work as well.
A geometry now contains zero or more geometry components.
A geometry component is a subclass off GeometryComponent.
Currently, there is a MeshComponent and PointCloudComponent.
A geometry contains at most one component of each type.
Individual components can be shared between multiple geometries
to avoid unnecessary copies. For that, each component has a user
count that determines when the component will be freed and whether
it is mutable.
Code working with geometries can either work with the components
directly, or use the utility functions on the geometry that cover the
most common operations.
In the future, additional component types can be added. For example,
we'll probably need components for curves and volumes.
Furthermore, something like an InstancesComponent can be added,
which contains points with attributes and references a geometry/object/collection
that is instanced on all the points.
The execute callback of a geometry node gets more domain specific
types as parameters now: GeoNodeInputs and GeoNodeOutputs.
Those types are also aware of what node is being executed and can
provide better error messages when they are used incorrectly.
The first is a "Point Distribute" node, which takes a mesh and outputs a
pointcloud, scattering points randomly on the surface based on the input
density. The distribution algorithm is extremely basic at this point, and
doesn't take into account an attribute weight at each vertex.
The second node is a "Point Instance" node, which is mainly a placeholder
until the engineering design for how to work with instancing in geometry
nodes is decided. For now it just runs the same code that the convert
pointcloud to mesh operator uses.
This adds another set of the same mesh functions but for pointclouds.
There are probably better ways to generalize this functionality, but that
may have to be rethought in the future anyway if we want to store
multiple of each type. And anyway it's handy to have a specific set of
"pointcloud" functions available in the node implementations.
This uses the code from the rewritten boolean modifier from 2.91 as a node.
The implementation is about as minimal as it can get, since for now the use
case of this node is mostly to test multiple geometry outputs and inputs.
The boolean code requires a BMesh, so the node converts the input meshes
to BMesh, so the bmesh is added as a dependency to the nodes module.
The settings can only be set via Python currently. The matching between properties
and group inputs is based on the socket identifier (which is e.g. `Input_5`).
Maybe we'll have to use a different matching strategy in the future, will see.
The properties are not used yet, but can already be accessed with Python
using `modifier.settings['setting name']`.
The plan is to use id properties to store the parameters that the modifier
passes into the geometry node group.
Group inputs are not yet exposed in the modifier. For now I just added
a simple float setting that will be passed to every float input of the group.
Inputs of other types have some default value.
We might not want to have all those nodes in a final version.
Some of them have been added with particle nodes in mind.
However, to test the evaluation system it is useful to have a
couple of nodes available.
Those nodes should "just" work, because their implementation
is reused from the particle nodes project.
This adds support for nodes that have a multi-function implementation.
That includes various function nodes like Math, Combine Vector, ...
Furthermore, there is support for implicit conversions now. So it should
work when one connects e.g. a float to an integer and vice versa.
These two functions "snode_notify" and "ED_node_tag_update_id" appear to
be mostly duplicates. However, there is already a case for each type of
built-in node tree, so it makes sense to add one for the geometry node
tree as well. This doesn't solve the update issues for changing number
in buttons, that must be handled somewhere else.
This adds a layer of abstraction between the code calling callbacks
on sockets and the implementation of those callbacks.
This abstraction layer allows some sockets to not implement all
callbacks when those can be derived from some other callback.
This is still very basic and does quite a few unnecessary computations.
Also the error handling is quite weak currently, so when invalid things are
connected, it will probably just crash.
Also the interface that individual nodes have to implement will have to change,
but the current solution is a good starting point.
Only the triangulate node is implemented for now.
