With the new `attrs_info_get` method, we can get information about
the attributes used in a `GPUShader` and thus have more freedom in the
automatic creation of `GPUVertFormat`s

With libepoxy we can choose between EGL and GLX at runtime, as well as
dynamically open EGL and GLX libraries without linking to them.
This will make it possible to build with Wayland, EGL, GLVND support while
still running on systems that only have X11, GLX and libGL. It also paves
the way for headless rendering through EGL.
libepoxy is a new library dependency, and is included in the precompiled
libraries. GLEW is no longer a dependency, and WITH_SYSTEM_GLEW was removed.
Includes contributions by Brecht Van Lommel, Ray Molenkamp, Campbell Barton
and Sergey Sharybin.

Intel iGPU (HD4000) supports OpenGL 4.4 but doesn't support conservative
depth. (GL_ARB_conservative_depth). This change will only check for the
availability of the extension.

This workaround and the issue was described in D4490. This makes sure
any shader using `shaderCreateInfo` will benefit from the same workaround.

Fix T97449 GPU subdivision: Crash on adding subdivision surface modifier
|
|
This commit removes all EEVEE specific code from the `gpu_shader_material*.glsl`
files. It defines a clear interface to evaluate the closure nodes leaving
more flexibility to the render engine.
Some of the long standing workaround are fixed:
- bump mapping support is no longer duplicating a lot of node and is instead
compiled into a function call.
- bump rewiring to Normal socket is no longer needed as we now use a global
`g_data.N` for that.
Closure sampling with upstread weight eval is now supported if the engine needs
it.
This also makes all the material GLSL sources use `GPUSource` for better
debugging experience. The `GPUFunction` parsing now happens in `GPUSource`
creation.
The whole `GPUCodegen` now uses the `ShaderCreateInfo` and is object type
agnostic. Is has also been rewritten in C++.
This patch changes a view behavior for EEVEE:
- Mix shader node factor imput is now clamped.
- Tangent Vector displacement behavior is now matching cycles.
- The chosen BSDF used for SSR might change.
- Hair shading may have very small changes on very large hairs when using hair
polygon stripes.
- ShaderToRGB node will remove any SSR and SSS form a shader.
- SSS radius input now is no longer a scaling factor but defines an average
radius. The SSS kernel "shape" (radii) are still defined by the socket default
values.
Appart from the listed changes no other regressions are expected.

This option lets specify explicitely how the fragment shader will change
the fragment's depth.

Metal shading language follows the C++ 14 standard and in some cases requires a greater level of explicitness than GLSL. There are also some small language differences:
- Explicit type-casts (C++ requirements)
- Explicit constant values (C++ requirements, e.g. floating point values using 0.0 instead of 0).
- Metal/OpenGL compatibility paths
- GLSL Function prototypes
- Explicit accessors for vector types when sampling textures.

This adds the possibility to use the `gpu_BaryCoord[NoPersp]`
builtin to support barycentric coordinates without geometry shader.
The `BuiltinBits::LAYER` builtin needs to be manually added
to the `GPUShaderCreateInfo` in order to use this feature.
Note: This is only available for shaders using `GPUShaderCreateInfo`.
A geometry shader fallback is generated if the extension
`AMD_shader_explicit_vertex_parameter` is not available.
`NV_fragment_shader_barycentric` was not considered because it is not
present inside the `glew.h` with use and seems to only be available
with vulkan.

The GLSL defines used to make the uniform names unusable for local variable
is being interpreted as recursive on some implementation.
This avoids it by create a second macro avoiding the recursion.
|
|
|
|
This is too much impractical and offers no real benefit.
|
|
Also adds a few things to GPUShader for easily create shaders.
Heavy usage of macros to compose the createInfo and avoid
duplications and copy paste bugs.
This makes the link between the shader request functions
(in workbench_shader.cc) and the actual createInfo a bit
obscure since the names are composed and not searchable.

This slipped through during a rebase.
|
|
In order to use a workaround builtin uniform, we need to count it
just like other uniforms and give it some space in the name buffer.
This also fixes extensions being added after the uniform declaration.
All `#extension` directives are now part of the gl backend.
|
|
All `#entension` directives needs to be first before any other
token. Add missing `;` after uniform declaration.
|
|
This makes optionnal the use of a different interface for the geometry
shader stage output. When the vertex and geometry interface instance name
matches, a `_in` and `_out` suffix is added to the end of the instance name.
This makes it easier to have optional geometry shader stages.

Cause was incorrect logic when generating the resource layout. It the
explicit_location_support setting was ignored and the binding were

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.
