vertex shader fetch.
These implementations remove dependency on the Geometry pass by instead invoking one vertex shader instance for each expected output vertex, matching what a geometry shader would emit. Each vertex shader instance is then responsible for calculating the same output position based on its vertex_id as the logic would in the geometry shader version.
SSBO Vertex fetch enables full random-access into a vertex buffer by binding it as a read-only SSBO. This enables each instance to read neighbouring vertex data to perform contextual calculations as a geometry shader would, for cases where attribute Multiload is not supported.

MTLContext provides functionality for command encoding, binding management and graphics device management. MTLImmediate provides simple draw enablement with dynamically encoded data. These draws utilise temporary scratch buffer memory to provide minimal bandwidth overhead during workload submission.
This patch also contains empty placeholders for MTLBatch and MTLDrawList to enable testing of first pixels on-screen without failure.
The Metal API also requires access to the GHOST_Context to ensure the same pre-initialized Metal GPU device is used by the viewport. Given the explicit nature of Metal, explicit control is also needed over presentation, to ensure correct work scheduling and rendering pipeline state.

From the nodes' description: "Retrieve the object that contains
the geometry nodes modifier currently being executed". This was
discussed in the most recent geometry nodes module meeting.
Because the node allows you to retrieve the position of the modifier
object, it has to add a depsgraph relation to object transform.
Expect that modifiers will be reevaluated when moving the object.
In the future, better static analysis of node trees could make this
check smarter.

As with the other uniform methods, a single value is expected.
|

The BMesh selection virtual array was empty. There are a few different
places we could add an "empty" check here, but at the top of the
function is the simplest for now.
|
|
Similar to e5a7470638803fd, the tree currently being edited should be
used for polling and other tests, rather than the node tree at the root
of the node editor's path.
|
|
Also make the disabled hint argument optional.
|
|
This was caused by the vertical/horizontal clasification being done in
NDC space which wasn't respecting the Aspect ratio.
Multiplying the test vector by the target size fixes the issue.

This removes some boilerplate when creating many optional attributes.
|
|
The typed "lookup_or_add_for_write_only" function is meant to do the
same thing as the non-typed version of the function. Instead, it still
initialized values of new attribute arrays, which isn't meant to happen.
Missed in 4c91c24bc7cbe2c4f97be373.
I also had to correct one place that used the "write_only"
function but didn't intialize all values.
|
|
I didn't observe this issue in practice, but since the write_only
version of the attribute API isn't meant to initialize trivial types,
theoretically this could be a problem if the attribute is created
halfway through converting the BMesh to a Mesh.

The BM_mesh_bm_to_me_for_eval() cal be called on the same BMesh
from multiple threads. This adds a restriction that this function
should not modify the BMesh. This started to be violated quite
madly during the generic attributes changes.
This change makes it so that the BMesh is not modified.
The code looks less functional-like, but it solves the threading
conflict.
Ideally the BMesh will be const in the function but doing it now
is a bit tricky due to the other APIs.
The repro case for the crash is a bit tricky to reproduce from
scratch. For those who has access to the Heis production repo
/pro/lib/char/pack_bot/pack_bot.blend file can be used. Simply
add loop to "GEO-leg.R" object and use bevel operator on the
new loop.
There is still some write of the element indices happening in
this function. In theory those could be removed (together with
the dirty index tag clear) but it leads to obscure crashes in
area far away from this one. I've left it unchanged for now as
on 64bit platforms those assignments should not be causing real
issues.

Base it in an existing building blocks rather than having dedicated
structure for it.
No functional changes is expected, just preparing to make the code
more reusable.
|
|
The ID nodes will use the provided component name to maintain
the map-based storage, while the component node itself could
override the empty name with a type name.
This lead to situations when it is not possible to lookup
the operation from its owner parameters.
|
|
Make it so find type of methods receive const pointers and do not
modify graph topology.
The latter was violated in the find_operation() which could have
created an empty component. This is not intended behavior.
No functional changes is expected.

They are not specific to the relations builder and could be

I'm adding some asset APIs/types in C++ that the file-listing code would
use. I prefer porting this code to C++ over adding a C-API for the asset
code.
Includes some minor cleanups that shouldn't change behavior, like using
`MEM_new()`/`MEM_cnew()`, C++ style C-library includes,
`LISTBASE_FOREACH()`, removing unnecessary typedefs, etc.

This functionality was present until Blender 2.80. Basically it adds back the
"+" and "-" buttons in the file browser when it stores an output filepath.
This is useful for someone rendering multiple versions of an animation (or a
composition) to compare.
At the moment this is used for the render output, and the File Output node in
the compositor.

05952aa94d33eeb504fa modified this area incorrectly, transforming
vertices outside of the mesh. That would have been fine, but the mesh
is used to retrieve the bounding box. Instead just avoid duplicating the
positions and normals completely, and avoid using referenced layers
just to be extra safe.

Selection
Regression introduced in rb2ba1cf4b40fc.
The `MLOOPUV_VERTSEL` flag only indicates UV selection without sync.

The extrude node must set the original indices for new faces to "None"
in edge mode as well. Same for new edges in vertex mode.
|
|
Even meshes without any faces must have MPoly and MLoop layers, etc.
This caused a crash in the extrude node when the edit mesh had no faces
(see T101208). Issue with f94130c94b24ac6578.
|
|
Caused due to an inaccuracy when the values of `in` and `out` are too
close.
The solution is to project the value of `in` directly onto the plane.
|
|
Use a consistent order of expressions and formatting.
Also use consistent error message text.

Face sets were not being initialized. I had also
forgotten to remove a dead struct member from
SculptBoundary which was being accessed.

Feeding -1 to BM_ELEM_CD_GET_VOID_P will not return NULL.

Now it's possible to set an offset in the surface reprojection.

After the redo panel is added to animation editors in D14960, many
operators have now been adjusted to appear and function correctly.
A full list of changes is tracked in T98195.
This patch only includes actual usability fixes. It does not do any
changes for the user's convenience, like adding other helpful properties
to operators. This can be done in a follow-up patch.

Add the Redo panel to the dopesheet & NLA editors. This also implicitly
adds it to the timeline editor, since it's a kind of action editor
internally.
This feature is needed for changing advanced properties of animation
operators, such as select grouped (see D14811). But it can also be
useful for existing operators, like precise keyframe position tweaking.
Changes are basically the same as in D6286 (which added the redo panel
for Graph Editor).
Some operators have internal properties that should be hidden. A full
list can be found in T98195. These will be fixed in a follow-up patch.

In large node setup the threading overhead was sometimes very significant.
That's especially true when most nodes do very little work.
This commit improves the scheduling by not using multi-threading in many
cases unless it's likely that it will be worth it. For more details see the comments
in `BLI_lazy_threading.hh`.

The operator did not set the any extrapolation mode of the individual
keyframes, it sets it for the whole f-curve. Change the operator name to
reflect that.
