On file read we need to update group nodes in case the group they refer to
has changed its inputs and outputs. This had O(n^2) time complexity and was
updating all datablocks even if they did not change.

Comments after code can cause awkward line breaks.
|

Was commented out for literally 10 years.

Similar to previous commit.
Compositing with animation on socket values and image sequences
still works fine.
|
|
The function was calling update() on the time curve, but there
is no update callback on that node. So, effectively the function
was doing nothing.

Apply clang format as proposed in T53211.

No functional change, this adds LIB definition and args to cmake files.
Without this it's difficult to migrate away from 'BLENDER_SORTED_LIBS'
since there are many platforms/configurations that could break when
changing linking order.
Manually add and enable WITHOUT_SORTED_LIBS to try building
without sorted libs (currently fails since all variables are empty).
This check will eventually be removed.
See T46725.

Causes extra-semicolon warning,
we'll need to disable clang-format for this file since it
won't format properly.

We were already getting the designated output node in
'ntreeGPUMaterialNodes()' but this wasnt used in 'ntreeExecGPUNodes()',
instead whatever node was tagged NODE_DO_OUTPUT was executed.
note: this is just the bare minimum to fix the bug, other improvements
previously done in D4482 might follow as a separate commit.

First try to implement T57489. But unfortunately, there is a missing
dependency in the depsgraph that does not trigger the shader update.
|
|
The wrong transformation was used. Add a new matrix specially for this case.
This also fix the Node texture coordinate that was suffering the same issue.
|
|
Pass binormal sign via object info.
|
|
This was caused by the material not tagged to use Diffuse lighting data.

This remove the RGB texture lookups if the curve is only used for "Luma"
correction and does not affect individual RGB channels.
|
|
Allow Python to override this method.

This was already supported for Cycles shader nodes, but now also works for
Eevee and compositing nodes. Instead of a generic NodeCustomGroup, now
there is ShaderNodeCustomGroup and CompositorNodeCustomGroup that can be
subclassed and registered.

User counting now happens before init() and after free() methods, so that
the ID users are in a valid state when Python might modify them. ID user
counting was moved into node.c and simplified.
Patch by Miguel with further refactoring by Brecht. Ref D4370.

Mostly functions wrapping args, not confirming to our style guide.

This is a hacky fix. We just convert the int as a float and use it as such.
This works ok for small int but will not be correct for numbers greater
than 4194303.
Correct support would require deeper change for UBO creation and socket
conversion.

Convention was not to but after discussion on 918941483f7e we agree its
best to change the convention.
Names now mostly follow RNA.
Some exceptions:
- Use 'nodetrees' instead of 'nodegroups'
since the struct is called NodeTree.
- Use 'gpencils' instead of 'grease_pencil'
since 'gpencil' is a common abbreviation in the C code.
Other exceptions:
- Leave 'wm' as it's a list of one.
- Leave 'ipo' as is for versioning.

The issue was that `bNodeSocketValueVector` and `bNodeSocketValueRGBA`
don't store the value at the same location in the struct.
I kept the cases for `SOCK_VECTOR` and `SOCK_RGBA` completely separate
for now, because they only share code by coincidence and not because
they are actually the same. Eventually there could be a "Vector Input"
node similar to the "RGB" node.

This was due to curve being not extrapolated correctly. Also curvemap range
was not taken into account.

Works as expected and mimics Cycles behavior.
The patch is a bit hacky: In order to not touch the lower level function,
we search for the active output inside groups (recursively) and the first
valid one is then copied (or extracted if you want) in the previous parent
nodetree. So we recursively extract the output node back to the main
nodetree while preserving the links through the nodegroups interfaces.
This way everything works as expected in gpu tree evaluation and bsdf
tagging.

The geom shader check was not needed and this uncovered an error in the
GPU_BARYCENTRIC_TEXCO optimization recently commited.

This fixes the general case. It is still not supported for hairs.
Added a hack in the geometry node to avoid unnecessary geometry shader
usage.

The dependency graph now handles updating image users to point to the current
frame, and tags images to be refreshed on the GPU. The image editor user is
still updated outside of the dependency graph.
We still do not support multiple image users using a different current frame
in the same image, same as 2.7. This may require adding a GPU image texture
cache to keep memory usage under control. Things like rendering an animation
while the viewport stays fixed at the current frame works though.

While \file doesn't need an argument, it can't have another doxy
command after it.
