- Texture creation now requires explicit data type.
- GPU_texture_add_mipmap enable explicit mipmap upload.
- GPU_texture_get_mipmap_size can be used to get the size of a mipmap level
of an existing GPUTexture
- GPU_texture_read let you read back data from a gpu texture.

Original description:
I've encounterd into a problem with blender 2.8.
See the example screenshot (scene, shader setup). For some materials it's not enough to calculate hash based on fragment code and defines. In some cases attribute names may change. And if we change uv set name, for example, vertex shader is not recompiled, and another attribute name inside it is used.

indexbuf generation.
It's cleaner, and actually assert that BMFace is a triangle. Same code
as when generating vertexbuf for flat shading!
|
|
We have to discard the batch in smooth case, because we are modifying
the index buffer (flat shading don't need it, only changes vertex buffer
on redraw, which is safe).
Many thanks to @fclem for his help on debuging/understanding what was
wrong here!

and types.
In an effort to centralize all opengl calls in the codebase, this patch replaces
the raw opengl calls in bf_blenfont with GPUTexture so it's no longer depended
on opengl headers.

this is to highlight areas in the code that still directly do opengl calls or use
opengl types.
This is in preparation for supporting alternative rendering back-ends.

The Eevee AO node supports the new Normal socket, but ignores Distance,
Samples, Inside and Only Local settings.
|
|
This means the shader can now be used for procedural texturing. New
settings on the node are Samples, Inside, Local Only and Distance.

This is important for good texture paint performance.
|
|
|
|
This includes making Eevee match Cycles behavior of inserting an emission
node when linking colors to closures.
|
|
This simplifies code, and will hopefully make UDIM usage of GPUTexture
a little easier.

This commit actually adds some G.main... but at much, much higher level
than the ones it removes, so should still be better ;)
|
|
This introduces a garbage collection system similar to gpu_texture.
|
|
|
|
|
|
Since we are only creating this and never updating, there is no need for
the original approach with the individual data to be updated.
Note we only populate the GPU data when binding the UBO, so we can in the
future easily create the UBOs in a separate thread than the main drawing one.
Also at the moment animated materials are not working. To fix that we need
to free/tag for free the GPUMaterials in BKE_material_eval.
|
|
|
|
|
|
|
|
And for the records, this shoudn't have been added to the
GPU_material_uniform_buffer_tag_dirty function since they are unrelated.
|
|
|
|
This is part of the work needed to refactor the material parameters update.
Now the gpupass cache is polled before adding the gpumaterial to the
deferred compilation queue.
We store gpupasses in a single linked list grouped based on their hashes.
This is not the most efficient way but it can be improved upon later.
