9155608875 Cleanup: Simplify handling of loop to poly map in normal calculation 
A Loop to poly map was passed as an optional output to the loop normal
calculation. That meant it was often recalculated more than necessary.
Instead, treat it as an optional argument. This also helps relieve
unnecessary responsibilities from the already-complicated loop normal
calculation code.
ddecc6166b GHOST/Wayland: replace roundtrip with dispatch_pending 
Add a non-blocking version wrapper for wl_display_dispatch_pending.

Noticed this when investigating T100855.

Note that performing a round-trip doesn't seem necessary from looking
into QT/GTK & SDL event handling loops.

431d527679 Fix: Curves sculptmode: deduplicate checks for being in mode 
rBa8f7d41d3898 added a "duplicate" check for being in curves sculptmode
unnecessarily afaict (`in_sculpt_curve_mode` in addition to the
previously existing `in_curves_sculpt_mode`).
Over time, the later evolved to also take into account the output of a
viewer node, see rBc55d38f00b8c (the previously existing
`in_curves_sculpt_mode` did not receive this).

This all results in the fact that selection is not drawn with a viewer
node (can be useful though, and there are separate opacity controls for
both selection and the viewer attribute, so these can be used/blended to
everyones liking).

So now deduplicate the check.

b5d4fbb9cc BLI: improve CPPType system 
* Support bidirectional type lookups. E.g. finding the base type of a
  field was supported, but not the other way around. This also removes
  the todo in `get_vector_type`. To achieve this, types have to be
  registered up-front.
* Separate `CPPType` from other "type traits". For example, previously
  `ValueOrFieldCPPType` adds additional behavior on top of `CPPType`.
  Previously, it was a subclass, now it just contains a reference to the
  `CPPType` it corresponds to. This follows the composition-over-inheritance
  idea. This makes it easier to have self-contained "type traits" without
  having to put everything into `CPPType`.

dce36e3e80 UV: implement copy and paste for uv 
Implement a new topology-based copy and paste solution for UVs.

Usage notes:

* Open the UV Editor

* Use the selection tools to select a Quad joined to a Triangle joined to another Quad.
* From the menu, choose UV > UV Copy
 * The UV co-ordinates for your quad<=>tri<=>quad are now stored internally

* Use the selection tools to select a different Quad joined to a Triangle joined to a Quad.
* (Optional) From the menu, choose UV > Split > Selection

* From the menu, choose UV > UV Paste
 * The UV co-ordinates for the new selection will be moved to match the stored UVs.

Repeat selection / UV Paste steps as many times as desired.
For performance considerations, see https://en.wikipedia.org/wiki/Graph_isomorphism_problem

In theory, UV Copy and Paste should work with all UV selection modes.
Please report any problems.

812de962a3 Fix T95335 Bevel operator Loop Slide overshoot. 
If the edge you are going to slide along is very close to in line
with the adjacent beveled edge, then there will be sharp overshoots.
There is an epsilon comparison to just abandon loop slide if this
situation is happening. That epsilon used to be 0.25 radians, but
bug T86768 complained that that value was too high, so it was changed
to .0001 radians (5 millidegrees). Now this current bug shows that
that was too aggressively small, so this change ups it by a factor
of 10, to .001 radians (5 centidegrees). All previous bug reports
remained fixed.

0c1b536c57 DRW: View: Add base for multi-view support 
This implements the base needed for supporting multiple view concurently
inside the same drawcall.

The view used by common macros and view related functions is indexed using
a global variable `drw_view_id` which can be set arbitrarly or read
from the `drw_ResourceID`.

This is needed for EEVEE-Next shadow but can be used for other purpose
in the future.

Note that a shader specialization is needed for it to work. `DRW_VIEW_LEN`
needs to be defined to the amount of view the shader will access.

The number of views contained in a `draw::View` is set at construction
time.

Note that the maximum number of object correctly drawn by the shaders
using multiple views will be lower than thoses who don't.

85cec1deff Asset system: New asset system code module (with files from BKE) 
Adds a new `source/blender/asset_system` directory and moves asset
related files from BKE to it. More asset related code can follow
(e.g. asset indexing, ED_assetlist stuff) but needs further work to
untangle it. I also kept `BKE_asset.h` and `asset.cc` as is, since they
deal with asset DNA data mostly, thus make sense in BKE.

Motivation:
- Makes the asset system design more present (term wasn't even used in
  code before).
- An `asset_system` directory is quite descriptive (trivial to identify
  core asset system features) and makes it easy to find asset code.
- Asset system is mostly runtime data, with little relation to other
  `Main`/BKE/DNA types.
- There's a lot of stuff in BKE already. It shouldn't be just a dump for
  all stuff that seems core enough.
- Being its own directly helps us be more mindful about encapsulating
  the module well, and avoiding dependencies on other modules.
- We can be more free with splitting files here than in BKE.
- In future there might be an asset system BPY module, which would then
  map quite nicely to the `asset_system` directory.

Checked with some other core devs, consensus seems that this makes
sense.

9d74da3352 Cycles: improve adaptive sampling for overexposed scenes 
Render time is reduced for overexposed scenes, by taking into account absolute
light intensity for adaptive sampling.

This can negatively affect some scenes where compositing or color management
are used to make the scene much darker or lighter. For best results adjust the
Film > Exposure setting to bring the intensity into a good range, and then do
further compositing and color management on top of that. Note that this setting
is different than color management exposure.

Previously Cycles' adaptive sampling used sqrt(I) to normalize noise level to
conform to a viewer's eye sensitivity. It is great for darker regions of the
image, but also requests too much samples in bright regions, sometimes several
times more than needed. Highlights can tolerate more noise because in most
examples it is still less noticeable then the noise in darker areas in the same
render.

96e93cc70c Mesh: Avoid calculating normals when building BVH tree

They are just calculated in the few places they are actually needed.
This should save at least a few percent of the runtime in some cases
where the normals weren't needed otherwise.

Consume events in a thread to prevent Wayland's event buffer from

From a users perspective this seemed like a crash.

Details:

- This is a workaround for a known bug in Wayland [0].
  Threaded event handling has been if-defed so it can be removed when
  it's no longer needed.

- GTK & QT use threaded event handling to avoid this problem
  (SDL on the other hand doesn't).

- The complexity and number of locks needed to handle events in a
  separate thread is a significant down-side, but as far as I can see
  this is necessary.

- Re-connecting to the Wayland server is possible but not practical as
  the OpenGL context is lost and as far as I can tell it's not possible
  to keep it active (see: D16492).

fc4c8a3647 Cleanup: Move OptiX denoiser code from device into denoiser class 
Cycles already treats denoising fairly separate in its code, with a
dedicated `Denoiser` base class used to describe denoising

(`denoiser_oidn.cpp`), but for OptiX was mostly empty
(`denoiser_optix.cpp`) and denoising was instead implemented in

files and directories, making it a bit awkward to work with. This
patch moves the OptiX denoising implementation into the existing
`OptiXDenoiser` class, so that everything is in one place. There are
no functional changes, code has been mostly moved as-is. To
retain support for potential other denoiser implementations based
on a GPU device in the future, the `DeviceDenoiser` base class was
kept and slightly extended (and its file renamed to
`denoiser_gpu.cpp` to follow similar naming rules as
`path_trace_work_*.cpp`).

15575b953d Merge By Distance: Optimize algorithm to find duplicate polygons 
The most time-consuming operation in merge by distance is to find
duplicate faces (faces that are different but have the same vertices).

Therefore, some strategies were planned to optimize this algorithm:
- Store the corner indices in an array thus avoiding multiple calls of `weld_iter_loop_of_poly_next`;
- Create a map of polygons linked to edges instead of linked to vertices - this decreases the number of connections and reduces the calculation of the intersection of polygon indices.

There are other fields to optimize, like reusing the `wpolys` array
instead of creating a new array of corner offsets. And join some arrays
as members of the same struct to be used in the same buffer.
But for now, it is already a nice optimization. And the new
`poly_find_doubles` function can be reused in the future to create a
generic utility.

The result of the optimization varies greatly depending on the number
of polygons, the size of each polygon and the number of duplicates.
On average it was something around 2 times faster.

21eff2c0ac 3DTexturing: Improve fix seam bleeding for manifold parts of mesh. 
Current implementation had some faulty assumtions and had some work
arounds for crashes that were actually limitation of the implementation.

The main reason for this was that the implementation didn't add new
primitives in the same direction it was already adding. Some when
incorrect behavior was detected it was assumed that the part wasn't
manifold (anymore) and didn't fix that part of the mesh.

The new implementation will extract a solution and use this solution
also as the order to generate primitives in uv space.

This patch fixes several crashes and improves the overall quality
when fixing seam bleeding. It also adds additional debug tools
(print_debug) implementation in order to find issues faster in the
future.

ae80a6696f Geometry Nodes: don't show warning in modifier with multiple geometry inputs 
Simon mentioned that this gets in the way more than it helps. No geometry

as node instead of as modifier.

In the future we could also allow e.g. choosing an object to pass into a geometry
socket. That has the problem that we'd also have to duplicate other functionality
of the Object Info node (original vs. relative space).
fdcb55b285 Cycles: Switch microfacet code to non-separable shadowing-masking term 
This gives closer results to what I've seen in papers and other renderers when
using the code to precompute albedo later (to replace MultiGGX).

It's usually a tiny difference, the only case where I've seen it matter is
in the `shader/node_group_float.blend` test - but that's a (single-scatter) GGX
closure with 0.9 roughness, so it's not too surprising. In any case, the new
result looks closer to Eevee, so that's good I guess.

Based on "Sampling the GGX Distribution of Visible Normals" by Eric Heitz

Also, this removes the lambdaI computation from the Beckmann sampling code and
just recomputes it below. We already need to recompute for two other cases
(GGX and clearcoat), so this makes the code more consistent.

In terms of performance, I don't expect a notable impact since the earlier
computation also was non-trivial, and while it probably was slightly more
accurate, I'd argue that being consistent between evaluation and sampling is
more important than absolute numerical accuracy anyways.

There is not much documentation on the "snap_point" property, but by

However, this property was still very dependent on Tools settings and

- do not change the state of the snap in the scene and

c5d9938adc Fix T104073: Unable to add more than two strips in one channel 
Originally, function `sequencer_generic_invoke_xy_guess_channel`
looked in what channel the last strip of the same type is and the
channel used for new strip placement. This was changed as a workaround
when sound strips were added below movie strips
(58bea005c5).
Now these workarounds aren't necessary, but the function was left
unchanged.

Current logic is for adding movie strip to channel 1 is:
- Sound is added to channel 1
- Video is added to channel 2
- If there is only video, it is added to channel 1

Since movie may, or may not contain sound, it is not possible to align
added strips in a way that was done before, unless timeline is analyzed
more in detail, but this would be quite inefficient.
Also, note, that the code did not work, if strip is added next to
previous one, so it mostly did not work as intended.

This commit changes:
- Fix alignment not working when strip is added right next to previous
  strip
- Assume that movie strips have sound strip underneath it, so channel
  below last movie strip is picked
- For other strip types, pick channel of the last strip of same type

Ultimately, the code is still rather weak, and better system, like using
channel where strip was manually moved, or concept of "typed channels"
would improve this feature.

This change will use sub-sampling to improve the quality. This is only

keep the user interface reacting as expected.

Another improvement is that image transform is stopped at the moment
it hadn't sampled at least 4 samples for a scan line. In that case we
expect that there are no further samples that would change to result.

In a future patch this could be replaced by a ray/bounding bo intersection
as that would remove some unneeded loops in both the single sampled and

This is required since a valid value is always written in .blend files

The issue was never detected so far because that pointer is explicitely
reset to NULL after filewrite, which includes any memfile undostep
write, and usually existing UI data is re-used instead of loading the

4e9c6929c1 VSE: Handle drivers when duplicating strips 
Most operations where strips are duplicated use `SEQ_animation` API,

When group of strips is duplicated and driver references other strip,
it will still reference original strip. However, this is much better,
than previous behavior, when strip duplication results in "transfer" of
driver from original strip to duplicated one.

89aae4ac82 Node Editor: Controlled node link swapping 
Allow to explicitly swap node links by pressing the alt-key while
reconnecting node links. This replaces the old auto-swapping based on
matching prefixes in socket names.

The new behavior works as follows:

* By default plugging links into already occupied (single input)
  sockets will connect the dragged link and remove the existing one.
* Pressing the alt-key while dragging an existing node link from one
  socket to another socket that is already connected will swap the
  links' destinations.
* Pressing the alt-key while dragging a new node link into an already
  linked socket will try to reconnect the existing links into another
  socket of the same type and remove the links, if no matching socket
  is found on the node. This is similar to the old auto-swapping.

Swapping links from or to multi input sockets is not supported.

This commit also makes the link drag tooltip better visible, when using
light themes by using the text theme color.

When moving or linking an object to a collection, the report was not

Instead, separate the report into the four possible translations (one

including plurals in languages which use grammatical agreement.

In addition, use BKE_collection_ui_name_get() to get the collection

57552f52b2 Metal: Realtime compositor enablement with addition of GPU Compute. 
This patch adds support for compilation and execution of GLSL compute shaders. This, along with a few systematic changes and fixes, enable realtime compositor functionality with the Metal backend on macOS. A number of GLSL source modifications have been made to add the required level of type explicitness, allowing all compilations to succeed.

GLSL Compute shader compilation follows a similar path to Vertex/Fragment translation, with added support for shader atomics, shared memory blocks and barriers.

Texture flags have also been updated to ensure correct read/write specification for textures used within the compositor pipeline. GPU command submission changes have also been made in the high level path, when Metal is used, to address command buffer time-outs caused by certain expensive compute shaders.

However, if the pool refresh operation occurs between encoding of work and submission, buffer ref-count is prematurely decremented.

fa9fc59b56 Fix T104240: OptiX OSL texture loading broken with displacement 
The image manager used to handle OSL textures on the GPU by
default loads images after displacement is evaluated. This is a
problem when the displacement shader uses any textures, hence
why the geometry manager already makes the image manager
load any images used in the displacement shader graph early
(`GeometryManager::device_update_displacement_images`).
This only handled Cycles image nodes however, not OSL nodes, so
if any `texture` calls were made in OSL those would be missed and
therefore crash when accessed on the GPU. Unfortunately it is not
simple to determine which textures referenced by OSL are needed
for displacement, so the solution for now is to simply load all of
them early if true displacement is used.
This patch also fixes the result of the displacement shader not
being used properly in OptiX.

023277359f Fix T104053: Limit pbvh recursion 
The recursion depth was checked for equality with a maximum depth,
allowing leaves with more primitives if a certain depth was reached.

However, a single leaf must always use the same material (including
set_smooth), so if a leaf contained multiple materials it was split
anyway. This meant that in the next recursion step the depth was
larger than the cutoff value and it would go back to recursing until
the number of primitives was small enough, ignoring the recursion
depth for the rest of the process.

In certain edge cases this could lead to a stack overflow.

Even with the check changed from 'equality' to 'larger or equal'
this could still fail in the pathological case where every primitive
has another material. But that can't be helped, and it wouldn't
realistically happen either.

For continued refactoring of the Mesh data structure. See T103343.
19b63b932d Fix transform gizmo not updating according to state 
Whenever a transform operation is activated by gizmo, the gizmo
modal is maintained, but its drawing remains the same even if the
transform mode or constrain is changed.

So update the gizmo according to the mode or constrain set.

NOTE: Currently only 3D view gizmo is affected
ebe8f8ce71 BMesh: Parallelize BMesh to evaluated Mesh conversion 
Currently this conversion (which happens when using modifiers in edit
mode, for example) is completely single threaded. It's harder than some
other areas to multithread because BMesh elements don't always know
their indices (and vise versa), and because the dynamic AoS format
used by BMesh makes some typical solutions not helpful.

This patch proposes to split the operation into two steps. The first
updates the indices of BMesh elements and builds tables for easy
iteration later. It also checks if some optional mesh attributes
should be added. The second uses parallel loops over all elements,
copying attribute values and building the Mesh topology.

Both steps process different domains in separate threads (though the
first has to combine faces and loops). Though this isn't proper data
parallelism, it's quite helpful because each domain doesn't affect the
others.

**Timings**
I tested this on a Ryzen 7950x with a 1 million face grid, with no
extra attributes and then with several color attributes and vertex
groups.

| File | Before | After |
| Simple | 101.6 ms | 59.6 ms |
| More Attributes | 149.2 ms | 65.6 ms |

The optimization scales better with more attributes on the BMesh. The
speedup isn't as linear as multithreading other operations, indicating
added overhead. I think this is worth it though, because the user is
usually actively interacting with a mesh in edit mode.

See the differential revision for more timing information.

d204830107 UI: Make uiBut safe for non-trivial construction 
No user-visible changes expected.

Essentially, this makes it possible to use C++ types like `std::function`
inside `uiBut`. This has plenty of benefits, for example this should help
significantly reducing unsafe `void *` use (since a `std::function` can hold
arbitrary data while preserving types).

----

I wanted to use a non-trivially-constructible C++ type (`std::function`) inside
`uiBut`. But this would mean we can't use `MEM_cnew()` like allocation anymore.

Rather than writing worse code, allow non-trivial construction for `uiBut`.
Member-initializing all members is annoying since there are so many, but rather
safe than sorry. As we use more C++ types (e.g. convert callbacks to use
`std::function`), this should become less since they initialize properly on
default construction.

Also use proper C++ inheritance for `uiBut` subtypes, the old way to allocate
based on size isn't working anymore.

7f958217ad Curves: Use shared caches for evaluated data 
Use the `SharedCache` concept introduced in D16204 to share lazily
calculated evaluated data between original and multiple evaluated
curves data-blocks. Combined with D14139, this should basically remove
most costs associated with copying large curves data-blocks (though
they add slightly higher constant overhead). The caches should
interact well with undo steps, limiting recalculations on undo/redo.

Options for avoiding the new overhead associated with the shared
caches are described in T104327 and can be addressed separately.

Simple situations affected by this change are using any of the following data
on an evaluated curves data-block without first invalidating it:
- Evaluated offsets (size of evaluated curves)
- Evaluated positions
- Evaluated tangents
- Evaluated normals
- Evaluated lengths (spline parameter node)
- Internal Bezier and NURBS caches

In a test with 4m points and 170k curves, using curve normals in a
procedural setup that didn't change positions procedurally gave 5x
faster playback speeds. Avoiding recalculating the offsets on every
update saved about 3 ms for every sculpt update for brushes that don't
change topology.

73000c792d Cycles: Reorganize Fresnel handling in Microfacet closures 
This is both a cleanup and a preparation for the Principled v2 changes.
Notable changes:
- Clearcoat weight is now folded into the closure weight, there's no reason
  to track this separately.
- There's a general-purpose helper for computing a Closure's albedo, which is
  currently used by the denoising albedo and diffuse/gloss/transmission color
  passes.
- The d/g/t color passes didn't account for closure albedo before, this means
  that e.g. metallic shaders with Principled v2 now have their color texture
  included in the glossy color pass. Also fixes T104041 (sheen albedo).
- Instead of precomputing and storing the albedo during shader setup, compute
  it when needed. This is technically redundant since we still need to compute
  it on shader setup to adjust the sample weight, but the operation is cheap
  enough that freeing up the storage seems worth it.
- Future changes (Principled v2) are easier to integrate since the Fresnel
  handling isn't all over the place anymore.
- Fresnel handling in the Multiscattering GGX code is still ugly, but since
  removing that entirely is the next step, putting effort into cleaning it up
  doesn't seem worth it.
- Apart from the d/g/t color passes, no changes to render results are expected.

8adebaeb7c Modifiers: measure execution time and provide Python access 
The goal is to give technical artists the ability to optimize modifier usage
and/or geometry node groups for performance. In the long term, it
would be useful if Blender could provide its own UI to display profiling
information to users. However, right now, there are too many open
design questions making it infeasible to tackle this in the short term.

This commit uses a simpler approach: Instead of adding new ui for
profiling data, it exposes the execution-time of modifiers in the Python
API. This allows technical artists to access the information and to build
their own UI to display the relevant information. In the long term this
will hopefully also help us to integrate a native ui for this in Blender
by observing how users use this information.

Note: The execution time of a modifier highly depends on what other
things the CPU is doing at the same time. For example, in many more
complex files, many objects and therefore modifiers are evaluated at
the same time by multiple threads which makes the measurement
much less reliable. For best results, make sure that only one object
is evaluated at a time (e.g. by changing it in isolation) and that no
other process on the system keeps the CPU busy.

As shown below, the execution time has to be accessed on the
evaluated object, not the original object.

```lang=python
import bpy
depsgraph = bpy.context.view_layer.depsgraph
ob = bpy.context.active_object
ob_eval = ob.evaluated_get(depsgraph)
modifier_eval = ob_eval.modifiers[0]
print(modifier_eval.execution_time, "s")

    Fixing this for other falloff and hardness could be a future improvement too.
  • The overlay should follow the style of the "Stabilize Stroke" setting.
    It should also only be visible whenever the stroke isn't applied on the surface yet.

  • The stroke is never properly concluded up to the boundary.
    Once the stroke continues on the mesh the stroke will jump to that point instead of starting anew.

  • Performance is also quite worse than regular textured strokes. Even a slower stroke does not fully help avoiding this.
