The current code for computing tangents is not exactly fast.
This has been a long-standing issue, and recently came up again with T97378.
The main bottleneck is fetching the mesh data, since it's handled through a callback system and each vertex might have its data queried dozens of times.
I've tried a lot of things to optimize `mikktspace.c`, but unfortunately most weren't that useful:
- Vectorizing SVec3 gives a ~5% speedup, but I'm not sure if the additional ~70 lines of code are worth it
- Keeping an internal copy of the data instead of re-querying all the time helps a lot (~50-60% time reduction), but requires a lot of extra memory (~100 byte per face)
- Going C++ and replacing the internal quicksort with std::sort shows no difference
- Restructuring the entire file to be a header-only library so that the callbacks can be inlined gives ~10% reduction, but is a major change and deviation from the original library
In the end, two simple fixes that actually help remain:
- Don't re-query the number of faces in each loop iteration
- Don't bother looking for identical vertices if there's only one vertex with that hash
With this, time for the test case in T97378 goes from 6.64sec to 4.92sec. It's something I guess.
I feel like completely refactoring this library would not be a bad idea at some point, but for now it does the job...

The uv fix just submitted had a bug where I forgot to wrap around
after adding 1. This apparently worked anyway in a debug build
but not in release build, hence the buildbot tests were failing.
Works for both Cycles and multires bake. Triangles are baked to multiple
UDIM images if they span across them, though such UV layouts are generally
discouraged as there is no filtering across UDIM tiles.
The bake margin currently only works within UDIM tiles. For the extend method
this is logical, for the adjacent faces method it may be useful to support
copying pixels from other UDIM tiles, though this seems somewhat complicated.

Remove need for shadow caustic caster geometry to have a UV layout. UVs were
useful to maintain a consistent tangent frame across the surface while
performing the walk. A consistent tangent frame is necessary for rough
surfaces where a normal offset encodes the sampled h, which should point
towards the same direction across the mesh.
In order to get a continuous surface parametrization without UVs, the
technique described in this paper was implemented:
"The Natural-Constraint Representation of the Path Space for Efficient
Light Transport Simulation" (Supplementary Material), SIGGRAPH 2014.
In addition to implementing this feature:
* Shadow caustic casters without smooth normals are now ignored (triggered
some refactoring and cleaning).
* Hit point calculation was refactored using existing utils functions,
simplifying the code.
* The max number of solver iterations was reduced to 32, a solution is
usually found by then.

This substantially redoes the logic by which bevel chooses, for
the middle segment when there are an odd number of segments,
which face to interpolate in, and which vertices to snap to which
edges before doing that interpolation. It changes the UV layouts
of a number of the regression tests, for the better.
An example, in the reference bug, is a cube with all seams, unwrapped
and then packed with some margin around them, now looks much
better in UV space when there are an odd number of segments.
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.

Python 3.10 has added "soft keywords" [0] to their list of identifiers.

The only soft keywords that Python 3.10 current has are: `match`,

Currently, the `_` soft keyword is ignored from highlighting. It is a
wildcard matching pattern when used with `case` (similar to `default`
for `switch`es in C/C++), but `_` is far more often used in other
contexts where highlighting the `_` might seem strange. For example,
ignoring elements when unpacking tuples (`_, g, _, a = color`).

setup the `MeshRenderData`.
As we do not seemingly have an `MDATA` wrapper, the draw code decides

This adds a new operator that converts all selected curves objects
into hair particle systems on their respective surface objects. Existing
particle systems with the correct name are updated, otherwise a new
particle system is added.
The purpose of the operator is the make the new curve sculpting tools
useful even before all functionality is ported over from the old hair system.
The operator can be found in the `Object > Convert` menu in object mode,
when a curves object is active.

When a `GPencilUpdateCacheNode` is created, it always allocates the
`children` pointer. This should not be freed until the whole cache is
deleted.
The `cache_node_update` would free the `children` pointer in a specific
case, causing a double-free later when the cache was removed.
The current behaviour is to prevent multi-user data from having its
transformation applied.
However in some particular cases it is possible to apply them:
* If all the users of the multi-user data are part of the selection.
* If not all the users are in the selection but the selection is made
single-user.
The active object is used as reference to set the transformation of the
other selected objects.
Note: For simplicity sake, this new behaviour is only available if all
the selection is using the same data.

The idea that curves with two points cannot be cyclic came from some
existing code, but there's not fundamental reason for it, so remove the
check in this function. The case can be handled elsewhere if necessary.
This commit adds calculation of lengths along the curve for each
evaluated point. This is used for sampling, resampling, the "curve
parameter" node, and potentially more places in the future.
This commit also includes a utility for calculation of uniform samples
in blenlib. It can find evenlyspaced samples along a sequence of points
and use linear interpolation to move data from those points to the
samples. Making the utility more general aligns better with the more
functional approach of the new curves code and makes the behavior
available elsewhere.

Fix small cosmetic issues with the reroute node:
1. Remove special case that allowed curved links to attach vertically.
2. Center align the reroute node's label.
The vertically attached node links could lead to kinks in the otherwise
smooth curves. This would break the visual flow and make the link
potentially intersect the node's label.
The center alignment of the label gives more consistent results for
different label lengths and also reduces the chance of the label
interfering with the node links.

Add new `BKE_id_is_editable` helper in `BKE_lib_id.h`, that supercedes
previous check (simple `ID_IS_LINKED()` macro) for many editing cases.
This allows to also take into account 'system override' (aka
non-editable override) case.
Ref: {T95707}.
'Delete' was a confusing name, even though it would delete the overrides
it would replace them by linked data.
Adding the 'single' version of that operation made it even more
confusing, since often it has to keep the override ID for sakes of
hierarchy, and just reset it and turn it back into a non-editable system
override.
Ref: {T95707}.
Implement default behavior to decide which overrides remain 'system'
ones, and which become 'user editable' ones, when creating hierarchy
override from 3DView or the Outliner.
3DView:
If from an Empty-instanced collection, only Armature objects in
that collection are user overrides.
If from a set of selected objects, all overrides created from selected
objects are user overrides.
Outliner:
All override IDs created from selected elements in the Outliner are user
overrides.
There is one special case: When a collection is selected, and is
'closed' in the outliner, all its inner armature objects are also user
overrides.
Ref: {T95707}.
When creating with hierarchies, core code only generates system
overrides, responsibility to define 'user overrides' is then for the
higher-level calling code (Editor/Operator-level).
do_version code uses fairly basic euristics, should be good enough here
though in most cases. and can always be refined later if needed.
Ref: {T95707}.
The whole liboverride data is still ignored by override diffing etc.,
but some of their flags should be editable (from script and/or advanced
technical/debug UI). So using a weird combination of flags to achieve
this.
Ref: {T95707}.
This merely adds the flag, exposes it in RMA, and uses it in some of the
most common 'is editable' checks (RNA, `BASE_EDITABLE` macro...).
Next step: do_version and defining systemoverrides at creation.
Ref: {T95707}.
The "dupli" system now has a faster, more powerful, and more flexible
alternative with geometry nodes. Since the point cloud objects haven't
been exposed in the non-experimental UI yet, we can remove the dupli
implementation and the panel for the object type.

Error exposed by ba49345705. Code just assumed that the tree-element

be a pointer to one of the `Main` listbases, so this code would have

For it to work, we also now need to preserve the subdivision loop to

Also the paint flag stored in the 4th dimension of the loop normal buffer
was not properly set for flat shaded faces, leading to other kind of
artefacts and render issues.
The problem was when the stroke had less weights that the total number of vertex groups.
The API checked the total number of groups, but this is not required because `BKE_defvert_find_index` returns NULL is the vertex group index does not exist.
If creating partial hierarchy overrides (from the outliner e.g.), that
need to create extra overrides, those could be re-created everytime,
leading to very bad situation where there would be several overrides of
the same reference ID in the same override hierarchy.
This fix makes it so that existing overrides in a given hierarchy will
always be re-used in case other overrides are added to the hierarchy.

Previously, those methods would destruct and reconstruct
the data structure. While that was more simple in initial
implementation, it has some downsides which are not resolved:
* Already allocated memory is lost. So new memory would have
to be allocated when the data structure is refilled.
* The clearing process itself was slower because it did unnecessary
work.
This simplifies debugging, and can help improve performance
by making it easier for the compiler.

If the `Automatic Constraint` modifier was activated while an axis
constraint was already set, the orientation used would be the default
orientation of the mode and not that of the scene.
This was because the `initSelectConstraint` function was not called in

indirect means.
So the solution is to call `initSelectConstraint` in either case and
remove these "indirect means" of enabling `Automatic Constraint`.
Contrary to the initial intention (in rB9916e0193c36), `TREDRAW_SOFT`

The mask is only used if it's not zero. Adding the normal mask made
it not zero, but it didn't include anything else, so all custom data
layers except normals were removed. The fix is to only add normals
to the mask when it should be used.
As described in T91186, this commit moves mesh vertex normals into a
contiguous array of float vectors in a custom data layer, how face
normals are currently stored.
The main interface is documented in `BKE_mesh.h`. Vertex and face
normals are now calculated on-demand and cached, retrieved with an
"ensure" function. Since the logical state of a mesh is now "has
normals when necessary", they can be retrieved from a `const` mesh.
The goal is to use on-demand calculation for all derived data, but
leave room for eager calculation for performance purposes (modifier
evaluation is threaded, but viewport data generation is not).
**Benefits**
This moves us closer to a SoA approach rather than the current AoS
paradigm. Accessing a contiguous `float3` is much more efficient than
retrieving data from a larger struct. The memory requirements for
accessing only normals or vertex locations are smaller, and at the
cost of more memory usage for just normals, they now don't have to
be converted between float and short, which also simplifies code
In the future, the remaining items can be removed from `MVert`,
leaving only `float3`, which has similar benefits (see T93602).
Removing the combination of derived and original data makes it
conceptually simpler to only calculate normals when necessary.
This is especially important now that we have more opportunities
for temporary meshes in geometry nodes.
**Performance**
In addition to the theoretical future performance improvements by
making `MVert == float3`, I've done some basic performance testing
on this patch directly. The data is fairly rough, but it gives an idea
about where things stand generally.
- Mesh line primitive 4m Verts: 1.16x faster (36 -> 31 ms),
showing that accessing just `MVert` is now more efficient.
- Spring Splash Screen: 1.03-1.06 -> 1.06-1.11 FPS, a very slight
change that at least shows there is no regression.
- Sprite Fright Snail Smoosh: 3.30-3.40 -> 3.42-3.50 FPS, a small
but observable speedup.
- Set Position Node with Scaled Normal: 1.36x faster (53 -> 39 ms),
shows that using normals in geometry nodes is faster.
- Normal Calculation 1.6m Vert Cube: 1.19x faster (25 -> 21 ms),
shows that calculating normals is slightly faster now.
- File Size of 1.6m Vert Cube: 1.03x smaller (214.7 -> 208.4 MB),
Normals are not saved in files, which can help with large meshes.
As for memory usage, it may be slightly more in some cases, but
I didn't observe any difference in the production files I tested.
**Tests**
Some modifiers and cycles test results need to be updated with this
commit, for two reasons:
- The subdivision surface modifier is not responsible for calculating
normals anymore. In master, the modifier creates different normals
than the result of the `Mesh` normal calculation, so this is a bug
fix.
- There are small differences in the results of some modifiers that
use normals because they are not converted to and from `short`
anymore.
**Future improvements**
- Remove `ModifierTypeInfo::dependsOnNormals`. Code in each modifier
already retrieves normals if they are needed anyway.
- Copy normals as part of a better CoW system for attributes.
- Make more areas use lazy instead of eager normal calculation.
- Remove `BKE_mesh_normals_tag_dirty` in more places since that is
now the default state of a new mesh.
- Possibly apply a similar change to derived face corner normals.

This patch implements the vector types (i.e:`float2`) by making heavy
usage of templating. All vector functions are now outside of the vector
classes (inside the `blender::math` namespace) and are not vector size
dependent for the most part.
In the ongoing effort to make shaders less GL centric, we are aiming
to share more code between GLSL and C++ to avoid code duplication.
####Motivations:
- We are aiming to share UBO and SSBO structures between GLSL and C++.
This means we will use many of the existing vector types and others
we currently don't have (uintX, intX). All these variations were
asking for many more code duplication.
- Deduplicate existing code which is duplicated for each vector size.
- We also want to share small functions. Which means that vector
functions should be static and not in the class namespace.
- Reduce friction to use these types in new projects due to their
incompleteness.
- The current state of the `BLI_(float|double|mpq)(2|3|4).hh` is a
bit of a let down. Most clases are incomplete, out of sync with each
others with different codestyles, and some functions that should be
static are not (i.e: `float3::reflect()`).
####Upsides:
- Still support `.x, .y, .z, .w` for readability.
- Compact, readable and easilly extendable.
- All of the vector functions are available for all the vectors types
and can be restricted to certain types. Also template specialization
let us define exception for special class (like mpq).
- With optimization ON, the compiler unroll the loops and performance
is the same.
####Downsides:
- Might impact debugability. Though I would arge that the bugs are
rarelly caused by the vector class itself (since the operations are
quite trivial) but by the type conversions.
- Might impact compile time. I did not saw a significant impact since
the usage is not really widespread.
- Functions needs to be rewritten to support arbitrary vector length.
For instance, one can't call `len_squared_v3v3` in
`math::length_squared()` and call it a day.
- Type cast does not work with the template version of the `math::`
vector functions. Meaning you need to manually cast `float *` and
`(float *)[3]` to `float3` for the function calls.
i.e: `math::distance_squared(float3(nearest.co), positions[i]);`
- Some parts might loose in readability:
`float3::dot(v1.normalized(), v2.normalized())`
becoming
`math::dot(math::normalize(v1), math::normalize(v2))`
But I propose, when appropriate, to use
`using namespace blender::math;` on function local or file scope to
increase readability.
`dot(normalize(v1), normalize(v2))`
####Consideration:
- Include back `.length()` method. It is quite handy and is more C++
oriented.
- I considered the GLM library as a candidate for replacement. It felt
like too much for what we need and would be difficult to extend / modify
to our needs.
- I used Macros to reduce code in operators declaration and potential
copy paste bugs. This could reduce debugability and could be reverted.
- This touches `delaunay_2d.cc` and the intersection code. I would like
to know @howardt opinion on the matter.
- The `noexcept` on the copy constructor of `mpq(2|3)` is being removed.
But according to @JacquesLucke it is not a real problem for now.

- We are aiming to share UBO and SSBO structures between GLSL and C++.
This means we will use many of the existing vector types and others
we currently don't have (uintX, intX). All these variations were
asking for many more code duplication.
- Deduplicate existing code which is duplicated for each vector size.
- We also want to share small functions. Which means that vector
functions should be static and not in the class namespace.
- Reduce friction to use these types in new projects due to their
incompleteness.
- The current state of the `BLI_(float|double|mpq)(2|3|4).hh` is a
bit of a let down. Most clases are incomplete, out of sync with each
others with different codestyles, and some functions that should be
static are not (i.e: `float3::reflect()`).
####Upsides:
- Still support `.x, .y, .z, .w` for readability.
- Compact, readable and easilly extendable.
- All of the vector functions are available for all the vectors types
and can be restricted to certain types. Also template specialization
let us define exception for special class (like mpq).
- With optimization ON, the compiler unroll the loops and performance
is the same.
####Downsides:
- Might impact debugability. Though I would arge that the bugs are
rarelly caused by the vector class itself (since the operations are
quite trivial) but by the type conversions.
- Might impact compile time. I did not saw a significant impact since
the usage is not really widespread.
- Functions needs to be rewritten to support arbitrary vector length.
For instance, one can't call `len_squared_v3v3` in
`math::length_squared()` and call it a day.
- Type cast does not work with the template version of the `math::`
vector functions. Meaning you need to manually cast `float *` and
`(float *)[3]` to `float3` for the function calls.
i.e: `math::distance_squared(float3(nearest.co), positions[i]);`
- Some parts might loose in readability:
`float3::dot(v1.normalized(), v2.normalized())`
becoming
`math::dot(math::normalize(v1), math::normalize(v2))`
But I propose, when appropriate, to use
`using namespace blender::math;` on function local or file scope to
increase readability.
`dot(normalize(v1), normalize(v2))`
####Consideration:
- Include back `.length()` method. It is quite handy and is more C++
oriented.
- I considered the GLM library as a candidate for replacement. It felt
like too much for what we need and would be difficult to extend / modify
to our needs.
- I used Macros to reduce code in operators declaration and potential
copy paste bugs. This could reduce debugability and could be reverted.
- This touches `delaunay_2d.cc` and the intersection code. I would like
to know @howardt opinion on the matter.
- The `noexcept` on the copy constructor of `mpq(2|3)` is being removed.
But according to @JacquesLucke it is not a real problem for now.
I would like to give a huge thanks to @JacquesLucke who helped during this

The issue was caused by Cycles display driver not being able to restore

This is due to the window OpenGL re-activation needing to access window

Defer clearing window manager from the global main to until after all
screens are "exited". This allows Cycles to properly stop rendering,
dispose its OpenGL context, and restore window's drawable context.
It is unclear why it was required to clear window manager list early

there was an early return which then got replaced with an actual logic

rBeed45d2a239a introduced a GPU backend for OpenSubDiv which lets us do
the subdivision at render time. However, some tools might still need to
have the subdivision data available on the CPU side. For this a
subdivision mesh wrapper was also introduced, and is computed whenever a
CPU side mesh is needed. The subdivision settings for this wrapper are
stored during modifier evaluation if GPU subdivision can be done.
The performance regression is due to the fact that although the
subdivision mesh was already computed on the CPU, and no subdivision
wrapper is generated, some checks for creating subdivision data in
`BKE_mesh_wrapper_ensure_subdivision` where still run, one of which is
very expensive.
To fix this we first check the runtime settings of the mesh to see if
subdivision is needed at all.

The core issue is that flushing dependencies are created from an object
to a node tree when it contains e.g. a Texture Coordinate node.
That is an issue because the evaluation of the node tree itself does not
depend on the object (node tree evaluation is essentially a no-op).
Only other systems that parse and evaluate the node tree in a specific
context actually depend on e.g. the position of the referenced object.
It can even be the case that the node tree depends on objects that
the actual evaluator (geometry nodes modifier/material) does not depend
on, because a node is not connected to the output.
Geometry nodes makes the distinction between dependencies to the
node tree and to the evaluator already. Shader nodes do not.
Therefore, shader nodes need a flushing relation from node groups
to their parent node groups.
This brings back some unnecessary updates from rB7e712b2d6a0d
(e.g. when creating a node group from nodes that are not connected
to the output). This is a bit unfortunate, but refactoring how
dependencies work with shader nodes is a out of scope for this fix.

Currently, most node buttons are defined in `drawnode.cc` however,
this is inconvenient because it requires editing many files when adding new nodes.

This commit moves most of the node layout functions for shader nodes into their respected
source/blender/nodes/shader/nodes file.
In the future, these functions will be simplified to node_layout.
Some nodes were left in `drawnode.cc` as this would require duplicating code
while this is likely fine it is best to leave that to a seperate commit.
Some software or processing tools (videogrammetry in this case) may
export malformed files with velocity data even when the frame is empty
for some reason. We need to explicity compare the data size with the
vertex size, and refuse to load the attribute if there is a data size
mismatch.
The dangling pointer caused errors further down the line.
The solution is to simply delete an internal link when one
of the corresponding sockets is removed (just like normal
links are removed as well).

The `lines_adjacency` IBO build in the GPU subdivision case was missing

This relation is intended to ensure that the properties of the IK

Weirdly enough, our 'mono' font already had it, but not the main one.
Copied from DeJaVu sans font.
CC @Tamuna who started the translation for that language.
This implements the design detailed in T92696 to support virtual
filenames for UDIM textures. Currently, the following 2 substitution
tokens are supported:
| Token | Meaning |
| ----- | ---- |
| <UDIM> | 1001 + u-tile + v-tile * 10 |
| <UVTILE> | Equivalent to u<u-tile + 1>_v<v-tile + 1> |
Example for u-tile of 3 and v-tile of 1:
filename.<UDIM>_ver0023.png --> filename.1014_ver0023.png
filename.<UVTILE>_ver0023.png --> filename.u4_v2_ver0023.png
For image loading, the existing workflow is unchanged. A user can select
one or more image files, belonging to one or more UDIM tile sets, and
have Blender load them all as it does today. Now the <UVTILE> format is
"guessed" just as the <UDIM> format was guessed before.
If guessing fails, the user can simply go into the Image Editor and type
the proper substitution in the filename. Once typing is complete,
Blender will reload the files and correctly fill the tiles. This
workflow is new as attempting to fix the guessing in current versions
did not really work, and the user was often stuck with a confusing
situation.
For image saving, the existing workflow is changed slightly. Currently,
when saving, a user has to be sure to type the filename of the first
tile (e.g. filename.1001.png) to save the entire UDIM set. The number
could differ if they start at a different tile etc. This is confusing.
Now, the user should type a filename containing the appropriate
substitution token. By default Blender will fill in a default name using
the <UDIM> token but the user is free to save out images using <UVTILE>
if they wish.

It is common to have fields that contain a constant value. Before this
commit, such constants were represented by operation nodes which
don't have inputs. Having a special node type for constants makes
working with them a bit cheaper.
It also allows skipping some unnecessary processing when evaluating
fields, because constant fields can be detected more easily.
This commit also generalizes the concept of field node types a bit.
Currently, a node either supports lazyness during execution (like the Switch
node), or it doesn't. If it does support lazyness, then every input is computed
lazily. However, usually not all inputs actually have to be computed lazily.
E.g. the boolean switch input is always required, while the other inputs
should be computed lazily.
Better support for such sockets can avoid unnecessary round trips through
the node execution function.
Exposes compare operations via rna emums.
This uses the rna enum to build the search list using
named operations linked to socket A.
This also weights the Math Node comparison operations lower

The logic used to be:
"if collection doesn't have child collection, check if ob is from this one"
The correct logic should be:
"if collection child does not have this ob, then check this collection".
In the past that worked because the `GPUMaterial` referenced the
`ImageUser` from the image node. However, that design was incompatible
with the recent node tree update refactor (rB7e712b2d6a0d257d272e).
Also, in general it is a bad idea to have references between data that is
owned by two different data blocks.
This incompatibility was resolved by copying the image user from the node
to the `GPUMaterial` (rB28df0107d4a8). Unfortunately, eevee depended
on this reference, because the image user on the node was update when the
frame changed. Because the image user was copied, the image user in the
`GPUMaterial` did not receive the frame update anymore.
This frame update is added back by this commit. The main change is that
the image user iterator now also iterates over image users in `GPUMaterial`s
on material and world data blocks. An issue is that these materials don't
exist on the original data blocks and that caused the check in
`build_animation_images` in the depsgraph to give the wrong answer.
Therefore the check is extended.
Right now the check is not optimal, because it results in more depsgraph
nodes than are necessary. This can be improved when it becomes cheaper
to check if a node tree contains any references to a video texture.
The node tree update refactor mentioned before makes it much easier
to construct this kind of run-time data from the bottom up, instead of
scanning the entire node tree recursively every time some information
is needed.
This just skips the entire algorithm when there are cycles.
In the future, cycles could be handled more gracefully in the
algorithm, but for now that's not worth it and is not necessary
to fix the bug.

When the material is used in several objects, the filter by material is not working as expected because the internal pointers are different due eval version.
Now, the original version of the material is compared to keep same address.
This is analagous to 6a71b2af66 which did the same
thing for mesh data. Two differences are that here the coordinates
are simply `float3`, and we account for the radius if it's available.
Here I observed a similar performance increase, from 50ms
average to 10ms average, with 16 million points, a 5x speedup.
The calculation is about 1.4 times faster when no radius is used, down
to 7.3ms average. Before, the calculation was only 1.2 times faster.
This was caused by a mistake in eb0eb54d96, which removed
the clearing of the curve edit mode pointers that are set when creating
the temporary data for the conversion. If they are not cleared, the
generic ID free function will also free the edit mode data, which is
wrong when the source curve is in edit mode.
At the time of allocating the buffer with vertices in context, we don't
know exactly how many vertices are affected, but we do know that it is
less than or equal to twice the number of vertices killed.
This just moves the relations update to a lower level function that is used
by other functions. Eventually, the special case for this node should be
generalized.
Ever since the instance domain was added, this was exposed, it just
didn't do anything. This patch implements the instances domain in the
delete and separate geometry nodes, where it acts on the top-level
instances.
We act on a mutable instances input, with the idea that eventually
copy on write attribute layers will make this less expensive. It also
allows us to keep the instance references in place and to do less
work in some situations.

since it will make it easier to add an integer mode that only

The calculation to find the factor between two evaluated points assumed
that the points were not at the same location. This assumption is some-
what reasonable, since we might expect `lower_bound` to skip those
point anyway. However, the report found a case where the first two
evaluated points were coincident, and there is no strong reason not
to make this safe, so add a check for 0 length before the division.

If the override system creates an override record for the cache

This is a safe fix that simply aborts the pointless rename attempt.

This evaluator is used in order to evaluate subdivision at render time, allowing for
faster renders of meshes with a subdivision surface modifier placed at the last
position in the modifier list.
When evaluating the subsurf modifier, we detect whether we can delegate evaluation
to the draw code. If so, the subdivision is first evaluated on the GPU using our own
custom evaluator (only the coarse data needs to be initially sent to the GPU), then,
buffers for the final `MeshBufferCache` are filled on the GPU using a set of
compute shaders. However, some buffers are still filled on the CPU side, if doing so
on the GPU is impractical (e.g. the line adjacency buffer used for x-ray, whose
logic is hardly GPU compatible).
This is done at the mesh buffer extraction level so that the result can be readily used
in the various OpenGL engines, without having to write custom geometry or tesselation
shaders.
We use our own subdivision evaluation shaders, instead of OpenSubDiv's vanilla one, in
order to control the data layout, and interpolation. For example, we store vertex colors
as compressed 16-bit integers, while OpenSubDiv's default evaluator only work for float
types.
In order to still access the modified geometry on the CPU side, for use in modifiers
or transform operators, a dedicated wrapper type is added `MESH_WRAPPER_TYPE_SUBD`.
Subdivision will be lazily evaluated via `BKE_object_get_evaluated_mesh` which will
create such a wrapper if possible. If the final subdivision surface is not needed on
the CPU side, `BKE_object_get_evaluated_mesh_no_subsurf` should be used.
Enabling or disabling GPU subdivision can be done through the user preferences (under
Viewport -> Subdivision).

The `BKE_animdata_driver_path_hack()` function has had almost no effect
since rB51b796ff1528, and basically boils down to:
```
return base_path ? base_path : RNA_path_from_ID_to_property(ptr, prop);
```
Since `base_path` was `NULL` in the majority of cases, it's just been
replaced by a direct call to `RNA_path_from_ID_to_property()`. The
conditional now just appears in one remaining case.

Do not allow 3DView operator to run on the liboverride of an

Related to T94226.
Note that this remains fairly exotic, bad idea not recommended cases,
such complex inter-dependencies between different libraries inside a
same liboverride hierarchy is just not possible to handle properly.
rBbd3bd776c893 broke compilation here due to missing type declaration
for basic types as the source file is not including this header. In any
case, it is the responsibility of header files to include headers for
types used by value in function parameters or struct definitions.
If the input mesh had no materials already, the new material would
become the only material on the mesh, meaning the material was
added to all of the faces, instead of just the selected faces.
The mesh primitive nodes in geometry nodes already add an empty
slot by default, so this only affects outside geometry.
The fix is just adding an empty slot before the new slot, so the
non-selected material indices can still point to an empty slot.

It's better to calculate the size of a spline before creating it, and this
should simplify refactoring to a data structure that stores all point
attribute contiguously (see T94193). The mesh to curve conversion is
simplified slightly now, it creates the curve output after gathering all
of the result vertex indices. This should be more efficient too, since
it only grows an index vector for each spline, not a whole spline.
Previously only the float version of the node was connected to.
This adds connection operations for vector sockets, and exposes
the "Steps" socket properly when it's selected.
Caused by capturing local variables by reference in a function that
outlives the scope it was created in. Also use a more generic function
for the first two inputs.
I don't think this has been visible, since I only ran into it after
changing other code that affected this. However, some attributes
can keep a reference to the source component to use when tagging
caches dirty (like the position attribute tagging the normals dirty).
Here, the component was created inside a function, then the attributes
were used afterwards.
Also add some comments warning about this in the header file.
When COM_EXPORT_GRAPHVIZ is enabled, DebugInfo::graphviz
uses a char[1000000] as local variable. When this function

This commit makes freeing a node tree about 25 to 30 times faster.
Freeing a node tree happens whenever it is edited. Freeing a node
tree with about 4000 nodes went from 30-50ms to about 2 ms.
This was so slow before because for every node that was freed
when freeing the node tree, `node_free_node` looped over all
other nodes to detach frames, and then looped over all links to
remove any links connected to the node. That was all pointless
work because everything else is about to be freed anyway.
Instead, move that "detaching" behavior to the dedicated function
for removing a single node, and to the "local" version of the free
function to be safe, since I know less about what that version expects.

Goals of this refactor:
* More unified approach to updating everything that needs to be updated
after a change in a node tree.
* The updates should happen in the correct order and quadratic or worse
algorithms should be avoided.
* Improve detection of changes to the output to avoid tagging the depsgraph
when it's not necessary.
* Move towards a more declarative style of defining nodes by having a
more centralized update procedure.
The refactor consists of two main parts:
* Node tree tagging and update refactor.
* Generally, when changes are done to a node tree, it is tagged dirty
until a global update function is called that updates everything in
the correct order.
* The tagging is more fine-grained compared to before, to allow for more
precise depsgraph update tagging.
* Depsgraph changes.
* The shading specific depsgraph node for node trees as been removed.
* Instead, there is a new `NTREE_OUTPUT` depsgrap node, which is only
tagged when the output of the node tree changed (e.g. the Group Output
or Material Output node).
* The copy-on-write relation from node trees to the data block they are
embedded in is now non-flushing. This avoids e.g. triggering a material
update after the shader node tree changed in unrelated ways. Instead
the material has a flushing relation to the new `NTREE_OUTPUT` node now.
* The depsgraph no longer reports data block changes through to cycles
through `Depsgraph.updates` when only the node tree changed in ways
that do not affect the output.
Avoiding unnecessary updates seems to work well for geometry nodes and cycles.
The situation is a bit worse when there are drivers on the node tree, but that
could potentially be improved separately in the future.
Avoiding updates in eevee and the compositor is more tricky, but also less urgent.
* Eevee updates are triggered by calling `DRW_notify_view_update` in
`ED_render_view3d_update` indirectly from `DEG_editors_update`.
* Compositor updates are triggered by `ED_node_composite_job` in `node_area_refresh`.
This is triggered by calling `ED_area_tag_refresh` in `node_area_listener`.
Removing updates always has the risk of breaking some dependency that no
one was aware of. It's not unlikely that this will happen here as well. Adding
back missing updates should be quite a bit easier than getting rid of
unnecessary updates though.

This happens because in `SEQ_time_update_sequence` function
`SEQ_get_meta_by_seqbase` returns uninitialized value. This isn't nice,
but it shouldn't happen in first place. Problem is, that
`SEQ_edit_strip_split` does move strips into detached `ListBase`, so
other functions can't see them anymore. Detached `ListBase` is used
solely to preserve relationships during duplication.
Move strips to original `ListBase` immediately after duplication and
return `NULL` if `SEQ_get_meta_by_seqbase` can't find meta strip.
Splitting itself can still rely on fact, that number of original and
duplicated strips is same and they are placed next to each other in
exactly same order at the end of original `ListBase`.
In this commit I changed many loops to range-based for loops.
I also removed some of the redundant iterator variables, using
indexing inside the loop instead. Generally an optimizing compiler

Both {key Alt} editing behavior as well as `Copy To Selected` were not
working on geometry nodes modifiers (even if these matched exactly -
having the same nodegroup - on multiple objects)
Reason is that code checks pointer equality on the discovered properties
[geometry nodes modifier properties are stored as ID properties], but
these are not the same across objects (since these are fetched from
NodesModifierSettings - which are different on different objects).
note: if general custom properties are "API defined" on existing classes,
this was working, we are getting the exact property for different IDs in
this case
Now be more permissive with ID properties not defined on classes in
general and dont check pointer equality for them. For ID properties on
specific IDs (not the ones defined on classes) this //might// be undesired
(havent spotted issues though, even if equally named ID properies with
different types existed -- this then simply does nothing).
For geometry nodes modifiers, new code also checks if the nodegroups are
the same [since generic naming "Input_XXX" is shared for all modifiers --
and starting to copy over things to unrelated modifiers is not desired
here].

This commit adds a search menu when links are dragged above empty
space. When releasing the drag, a menu displays all compatible
sockets with the source link. The "main" sockets (usually the first)
are weighted above other sockets in the search, so they appear first
when you type the name of the node.
A few special operators for creating a reroute or a group input node
are also added to the search.
Translation is started after choosing a node so it can be placed
quickly, since users would likely adjust the position after anyway.
A small "+" is displayed next to the cursor to give a hint about this.
Further improvements are possible after this first iteration:
- Support custom node trees.
- Better drawing of items in the search menu.
- Potential tweaks to filtering of items, depending on user feedback.

Previously we used a `CellValue` class to hold the data for a cell,
and called a function to fill it whenever necessary. This is an
unnecessary complication when we have virtual generic arrays
and most data is already easily accessible that way anyway.
This patch removes `CellValue` and uses `fn::GVArray` to provide
access to data instead.
In the future, if rows have different types within a single column,
we can use a `GVArray` of `blender::Any` to interface with the drawing.
Along with that, the use of virtual arrays made it easy to do a
few other cleanups:
- Use selection domain interpolations from rB5841f8656d95
for the mesh selection filter.
- Change the row filter to only calculate for necessary indices.

This patch refactors the instance-realization code and adds new functionality.
* Named and anonymous attributes are propagated from instances to the
realized geometry. If the same attribute exists on the geometry and on an
instance, the attribute on the geometry has precedence.
* The id attribute has special handling to avoid creating the same id on many
output points. This is necessary to make e.g. the Random Value node work
as expected afterwards.
Realizing instance attributes has an effect on existing files, especially due to the
id attribute. To avoid breaking existing files, the Realize Instances node now has
a legacy option that is enabled for all already existing Realize Instances nodes.
Removing this legacy behavior does affect some existing files (although not many).
We can decide whether it's worth to remove the old behavior as a separate step.
This refactor also improves performance when realizing instances. That is mainly
due to multi-threading. See D13446 to get the file used for benchmarking. The
curve code is not as optimized as it could be yet. That's mainly because the storage
for these attributes might change soonish and it wasn't worth optimizing for the
current storage format right now.

Calling `foreach_field_input` on a highly nested field (we do that

That is because the same node may be visited many times.
This made Blender freeze on some setups that should work just fine.
Now every field keeps track of its inputs all the time. That replaces
the exponential algorithm with constant time access.
This allows to use fewer evaluations (30 msec down to 23 for me) while giving more accurate results (3x-10x less relative absolute error) compared to classic ray marching.
Not a massive difference, but meh, it's better. For Cycles the speedup doesn't really matter much, but I also have a patch for Eevee support.
I've also tried Gauss-Legendre and Gauss-Lobatto - the latter was always worse, while the former was slightly better at 2deg elevation but notably worse on 15deg.

When loading huge images (30k) blender crashed with a buffer overflow.
The reason is that determine the length of a buffer was done in 32bit

This patch adds a new function to do the correct calculation in 64bit.
It should be added to other sections in blender as well. But that should
be tested on a per case situation.
When rendering volume surfaces in unbounded worlds the volume stepping can produce large values. If used with a magic texture node the values can results in a Inf float which when used in a sin or cos produces a NaN.
To fix this the input values are mapped into the periodic range of the sin and cos functions (-2*PI 2*PI) this stops the possibility of a Inf occurring and thus the NaN. It also improves the accuracy and smoothness of the result due to loss of precision when large values are summed with smaller ones effectively removing the parts of the smaller number (i.e. those in the -2PI to 2PI range) that result in variation of the output of sin and cos.

This was an issue with the mixed list of external assets and assets from
the current file. When closing the File Browser to select the custom
preview image, the assets from the current file would be cleared for
reread, to make sure we display up-to-date file data. That is because
the workspace of the temporary File Browser was deleted, causing a
change in the file data (main data-base). The reread would happen in a
background thread, meaning it might not finish before the custom preview
operator runs and queries the active asset. So the preview operator
would get the wrong active asset from context.
Two fixes were needed:
* Make sure current file data is reread before the operator runs, by
doing this partial rereading on the main thread.
* Ensure the asset list (in fact file list) order stays consistent over
rereads. If multiple assets with the same name were shown, the
operator might also have gotten the wrong asset, also leading to a
crash.
Additionally the file operation handler should probably poll before
executing, to fail gracefully at least (not crash).
A crash happened when `instance_id_attribute` further down in the
function was null. This issue was probably introduced when the
id attribute starting using generic attribute handling.

The type conversions do not depend on other files in the nodes

The `node_storage` functions to retrieve const and mutable structs

The original move to c++ that the other commits depended upon had some issues
that should be fixed before committing it again. The issues were reported in
T93797, T93809 and T93798.
We should also find a better rule for not using c-style casts going forward,

Error in d5efda72f5. Was changing an iteration that would free items
to an iterator that is not safe for use in such cases.
There still seem to be significant issues with the rendering, but that's
a separate issue to be fixed.
Issue is that external engine uses the gpu info. but overwrote the
instance data. The draw manager would then detect instance data and
required the engine type to have a instance free callback.
The solution is to save some space in the engine data to hold an empty
and unused instance_data attribute to comply with `ViewportEngineData`
struct.
In the original design draw engines had to copy with a limitation that
they were not allowed to reuse complex data structures between drawing
calls. Data that could be reused were limited to:
- GPUFramebuffers
- GPUTextures
- Memory that could be removed calling MEM_freeN (storage list)
- DRWPass
This is fine when the storage list contains arrays or structs but when
more complex data types (vectors, maps) etc wasn't possible.
This patch adds instance_data that can be reused between drawing calls.
The instance_data is controlled by the draw engine and doesn't need to
be limited as described above.
When an engines stores instance_data it must implement the
`DrawEngineType.instance_free` callback to free the data.
The patch originates from eevee rewrite. But was added to master as the
image engine rewrite also has a need for it.

The resample node didn't handle the case of when a spline didn't have
any evaluated points. For poly and Bezier splines we should never hit
this case, but it is expected when the number of NURBS control points
is smaller than its order, so we have to handle the case here.
It's not that obvious what to do in this case, there are a few options:
- Remove the bad splines from the result
- Generate empty splines for those inputs
- Skip resampling the bad splines, copy them to the result
- Arbitrarily generate single point splines
I chose option three, just skipping the "bad" splines. Since the node
already has a selection input, this can be described by just extending
that. "Splines with no evaluated points are implicitly deselected."
The first option would probably be valid too though.

Above commit was trying to get the vertexgroup from the mesh that is

When can it be NULL, when is is non-NULL?
`editbmesh_calc_modifiers` only passes in a non-NULL mesh to

- a non-deform-only modifier is handled currently
- a non-deform-only modifier preceeds the current modifier
- a deform-only modifier preceeds the current modifier (and the current
one depends on normals)

This puts all static functions in geometry node files into a new

compile times significantly
- The namespace name is derived from the file name.
That makes it possible to write some tooling that checks the names later on.
The filename extension (cc) is added to the namespace name as well.
This also possibly simplifies tooling but also makes it more obvious that this namespace is specific to a file.
- In the register function of every node, I added a namespace alias namespace `file_ns = blender::nodes::node_shader_*_cc`;.
This avoids some duplication of the file name and may also simplify tooling, because this line is easy to detect.
The name `file_ns` stands for "file namespace" and also indicates that this namespace corresponds to the current file.

As a followup to 338c1060d5, apply the same change to the node
drawing callback. This helps to simplify code when the complexity
of a callback isn't necessary right now.
Currently there are a few callbacks on `bNodeType` that do the same
thing for every node type except reroutes and frame nodes. Having a
callback for basic things complicates code and makes it harder to
understand, and reroutes and frames are special cases in larger way.
Arguably frame nodes shouldn't even be drawn like regular nodes,
given that it adds a case of O(N^2) looping through all nodes.
"Unrolling" the callbacks makes it easier to see what's happening,

`GeometrySet` contains at most one component of each type.
Previously, a map was used to make sure that each component
type only exists once. The overhead of a map (especially with
inline storage) is rather large though. Since all component types
are known at compile time and the number of types is low,
a simple `std::array` works as well.
Some benefits of using `std::array` here:
* Looking up the component of a specific type is a bit faster.
* The size of `GeometrySet` becomes much smaller from 192 to 40 bytes.
* Debugging a `GeometrySet` in many tools becomes simpler because
one can easily see which components exists and which don't
The problem is that `current_mask` can become `selection.size()`.
The loop could also be refactored to break out of it when the end
of the selection is reached. This can be done separately.

- Group Nodes
- Image input node

Cycles preview rendering could free the image buffers being used by drawing in
another thread due to a race condition. This race condition was unlikely before,
but now that preview renders are started right before we draw the image in the

As we are close to release this is too risky to fix properly, just avoid freeing
the cache for preview renders instead and accept increased memory usage in some

keep the (non-manifold) boundaries of the mesh intact.
Attributes are propagated:
- Point domain goes to face domain and vice versa
- Edge domain and Face corner domain gets mapped to itself
Because of the duality, when the mesh is manifold, the attributes get
mapped to themselves when applying the node twice.

Note that this does not work well with some non-manifold geometry,

When enabling or disabling a Mesh Sequence Cache modifier of an Object
with a hair particle system, the hair would switch positions. This is
caused because original coordinates in Blender are expected to be
normalized, and toggling the modifier would cause the usage of different
orco layers: one that is normalized, and the other which isn't.
This bug exposes a few related issues:
- if the Alembic file did not have orco data,
`MOD_deform_mesh_eval_get`, used by the particle system modifier, would
add an orco layer without normalization
- `MOD_deform_mesh_eval_get` would also ignore the presence of an orco
layer (e.g. one that could have been read from Alembic)
- if the Alembic file did have orco data, the data would be read
unnormalized
To fix those various issues, original coordinates are normalized when
read from Alembic and unnormalized when written to Alembic; and a new
utility function `BKE_mesh_orco_ensure` is added to add a normalized
orco layer if none exists on the mesh already, this function derives
from the code used in the particle system.

we considered the performance trade-off reasonable.
- The performance difference reduces with larger scenes,

the same or slightly better overall performance.

The poll for unlinking calls `nla_panel_context` without providing an
adt pointer, and there is a check for this pointer in
`nla_panel_context` leading to never returning true if it is not
provided. (this is fine if there are tracks already, poll would succeed
in this case, `nla_panel_context` goes a different code path then)
Same call to `nla_panel_context` is also done in the beginning of the
corresponding unlink exec function (but this time providing the pointer
because it is used later), so it makes sense to do the same thing in the
poll function. Equal check is also done in the panel poll function, so
now these are all in sync.

Clearing the parent from the UI using the X (or from python) clears the

Using the Clear Parent operator would leave the `parsubstr` (and thus
`parent_bone`) untouched even though this operator claims to "clear
parenting relationship completely" (it also removes parent deform

So now, also clear `parsubstr` and set back to `PAROBJECT` [which is

Add Apply Constraint, Duplicate Constraint, and Copy To Selected

The shortcuts in the extras menu are also matched to modifiers.
All the here added operators are intended to work exactly like the
analogous ones for modifiers. That means the apply operator should apply
a constraint as if it was first in the list, just like modifiers do. I
have added the same warning message as for modifiers when that happens.
The decision to use this approach of appling the constraint as if it was
first, was made for consistency with modifiers. People are already used
to how it works there. Is also provides more intricate control over the
applied transforms, then just applying all constraints up to that one.
Apply all constraints is already kinda implemented in Bake Animation.

During the processing of a continuous drag event, other mouse move
events may be in the queue waiting to be processed.
But when a mouse wrapping happens, these waiting mouse move events
become out of date as they report a mouse position prior to wrapping.
The current code ignores these events by comparing their `timestamp` to
the time recorded in the last mouse wrapping.
The bug happens because the computed value in
`mach_absolute_time() * 1e-9` for some reason is incompatible with the

The function `BKE_idtype_idcode_is_valid(short idcode)` was used to

For `TEST` blocks, it would actually consider it a `TE` block, which is

This is more of a work-around actually, since there is no real way to

Note that this is not a normal expected situation, and it won't give a
proper resync result anyway, but it might happen in some complicated
corner cases, and also quite often when dealing with older .blend files.
In some cases (advanced, low-level), we also want to remap pointers like

This took more than a day to fully investigate and understand, one of
the reasons being that the probability of the issue to show up was
extremely low, and subjected to very specific random factors.
Root of the issue is that, in some very rare cases, a newly read ID
might get the exact same memory address as the one it had when the blend
file was saved.
In that case, `BKE_workspace_active_set` would return immediately, since
the pointer to the active workspace would remain unchanged. But that
lead to having an unset NULL active layout pointer, which would crash
when attempting to get e.g. the active screen.
For the record, I ran into this when running a specific build (master
with one flag added to the `LIB_ID_CREATE` ones, with value `1 << 3`),
using a specific set of options (`--background --factory-startup -noaudio`),
and passing the .blend file from T80090 as argument.
Remove the attempt to update the active layout pointers of each window
from whithin `direct_link_workspace`.
This piece of code was a nonsense for at least to critical reasons:
* Do not, never, ever, access data from another datablock within the
direct_link_... functions. Just don't. Don't try to be smart.
* Since it was trying (and failing) to update the active layout of every
window for every workspace, it was effectively setting those
`act_layout` pointers to NULL (remapping can only ever happen once,
trying to remap and already remapped new pointer is bound to fail in
any case).
Luckily (and funnily), this piece of code was actually harmless, since
setting the active layout would be overridden/redone later, in
`lib_link_windowmanager`, when updating their `workspace_hook` in
`lib_link_workspace_instance_hook`.
Note that the similar horror with `WorkSpaceDataRelation->parent` (which
points at a window) is kept for now, because that one is needed. Hope to
refactor it soon though.
Although I haven't seen this cause any visible errors, there is some
incorrect handling for setting panel expansion during search:
- Properly check if child panel is active first
- Don't stop traversal at headerless panels that could theoretically
have children
This is part of the Vulkan backend task T68990.
This is mostly a cleanup, however, there is a small change:
We don't use a special Vertex Array binding function for Immediate

This might create a bit more state changes but this could be fixed
