Use a shorter/simpler license convention, stops the header taking so
much space.

While most of the source tree has been included
- `./extern/` was left out.
- `./intern/cycles` & `./intern/atomic` are also excluded because they

To avoid that, we simply filter using a debug group.
|
|
This is then easier to include in other modules.
|

Source files are now only referenced and listed for the driver to ingest.
Shader sources now includes generated data if any.
Also cleans up gpu_shader_dependency_get_builtins casts.

- Scan all static shaders for builtins on startup.
- Add possibility to manually add builtins.
- `ShaderCreateInfo.builtins_` contain builtins from all stages.

This allows to check if a create_info extists based on its name.

This patch migrates the draw manager hair refine compute shader to use
GPUShaderCreateInfo.

This function will be used as the way to build shaders from
create_infos. The previous used method was using a private function.

This is a first part of the Shader Create Info system could be.
A shader create info provides a way to define shader structure, resources
and interfaces. This makes for a quick way to provide backend agnostic
binding informations while also making shader variations easy to declare.
- Clear source input (only one file). Cleans up the GPU api since we can create a
shader from one descriptor
- Resources and interfaces are generated by the backend (much simpler than parsing).
- Bindings are explicit from position in the array.
- GPUShaderInterface becomes a trivial translation of enums and string copy.
- No external dependency to third party lib.
- Cleaner code, less fragmentation of resources in several libs.
- Easy to modify / extend at runtime.
- no parser involve, very easy to code.
- Does not hold any data, can be static and kept on disc.
- Could hold precompiled bytecode for static shaders.
This also includes a new global dependency system.
GLSL shaders can include other sources by using #pragma BLENDER_REQUIRE(...).
This patch already migrated several builtin shaders. Other shaders should be migrated
one at a time, and could be done inside master.
There is a new compile directive `WITH_GPU_SHADER_BUILDER` this is an optional
directive for linting shaders to increase turn around time.
What is remaining:
- pyGPU API {T94975}
- Migration of other shaders. This could be a community effort.

Added optional `name` argument to `GPUShader` constructor
(defaults to `pyGPUShader`), and added `name` getter to `GPUShader`.

Current compiler log parser is to complex to follow. Moving it to its
own compile unit before refactoring.

These were limited to obvious cases. Some less obvious cases
were kept as refactoring might make them necessary in future.

With the compute pipeline calculation can be offloaded to the GPU.
This patch only adds the framework for compute. So no changes for users at
this moment.
NOTE: As this is an OpenGL4.3 feature it must always have a fallback.
Use `GPU_compute_shader_support` to check if compute pipeline can be used.
Check `gpu_shader_compute*` test cases for usage.
This patch also adds support for shader storage buffer objects and device only
vertex/index buffers.
An alternative that had been discussed was adding this to the `GPUBatch`, this
was eventually not chosen as it would lead to more code when used as part of a
shading group. The idea is that we add an `eDRWCommandType` in the near
future.

Resolves occasional glitch/flicker drawing dark buttons in the UI.
Regression in 405a5d3bd7ada5dd5af605b59ba07c7144f144a2
which removed shader unbinding when the batch is drawn.
GPU_shader_bind could run with the sRGB uniform in an unexpected state.

This is work in progress, but it is very useful even as it is.

Modernize loops by using the `for(type variable : container)` syntax.
Some loops were trivial to fix, whereas others required more attention
to avoid semantic changes. I couldn't address all old-style loops, so
this commit doesn't enable the `modernize-loop-convert` rule.
Although Clang-Tidy's auto-fixer prefers to use `auto` for the loop
variable declaration, I made as many declarations as possible explicit.
To me this increases local readability, as you don't need to fully
understand the container in order to understand the loop variable type.
No functional changes.

This was a leftover from the 2.91 GPU module refactor.
This is an exception that should be removed when we remove BGL.

Replace `NULL` with `nullptr` in C++ code.
No functional changes.

This removes the escape color control caracters when the output
does not supports it (i.e: file output, windows cmd).
|
|
Following the most widely used convention for including todo's in
the code, that is: `TODO(name):`, `FIXME(name)` ... etc.
|
|
This makes the GPUContext follow the same naming convention as the rest
of the module.
Also add a static getter for extra bonus style (no need for casts):
- Context::get()
- GLContext::get()
|
|
- Use the syntactic wrap/unwrap method to make code more readable.
- Update comment about hidden struct behind opaque types.
- Cleanup GPUDrawList type.
|
|
This makes more sense as this module has more to it than just
GL extensions.
|
|
No functional changes
|
|
- Print shader type (fragment, vertex, geom)
- Support for Apple + intel error format.
- Handle formatting a bit more gracefully.
|
|
This avoids the misleading inheritance.
Also cleanup by setting the blender::gpu::Shader as active shader to
avoid some casting.
|
|
The shader name is required with the latest changes.
|
|
This follows the GPU module naming of other buffers.
We pass name to distinguish each GPUUniformBuf in debug mode.
Also remove DRW_uniform_buffer interface.

Use macro to get calling function name. Helps debugging shaders.
|

Now error printing only display the line related to the error.
We also put char marker if present.
Example:
```
-- Shader Compilation Errors : MAMaterial --
10414 | node_fresnel(, facingnormal, viewposition, tmp34);
| ^
| error: syntax error, unexpected ',', expecting ')'

This changes the drawing paradigm a bit. The VAO configuration is done
JIT-style and depends on context active shader.
This is to allow more flexibility for implementations to do optimization
at lower level.
The vao cache is now its own class to isolate the concept. It is this
class that is reference by the GLContext for ownership of the containing
VAO ids.
|
|
|
|
This remove the use of batch->program and replace it with batch->shader.
This will allow GL abstraction latter.
