Almost 1:1 identical to UniformBuf implementation.
|
|
This adds detection of the maximum number of shader storage buffer
bindings that is supported on the current platform. This can be
useful to turn off features that require compute shaders but use
more buffer bindings than available.

Some drivers for legacy platforms seem to have issues with compute
shaders, as revealed by T94936. This disables compute shader for the
known drivers where this issue is present. It is not clear if the issue
is Windows only or not, so this disable them for all operating systems.
See T94936 for a list of configurations where the issue is reproducible
or not.

This is an OpenGL 4.3 feature that enables creating a texture using a range
of the same data as another texture.
|
|
This means textures need to have the number of mipmap levels specified
upfront. It does not mean the data is immutable.
There is fallback code for OpenGL < 4.2.
Immutable storage will enables texture views in the future.

This can happen when the attribute has been optimized out by the compiler.
|
|
|
|
Optimized out attributes returns an invalid location `-1` resulting in
an undefined behavior shift.
|
|
|
|
|
|
The check was reversed, leading to less errors being reported.
|
|
Use using instead of typedef, remove redundant string init,
use "empty", address qualified auto, use nullptr.

Currently whenever gl queries are performed for the viewport, a large
1024 byte array is allocated to store the query results (256 of them).
Unfortunately, if any gizmo using a `draw_select` callback is active
(e.g. the transform gizmos), these queries (and allocations) will occur
during every mouse move event.
Change the vector to allow for up to 16 query results before making an
allocation. This provides enough space for every built-in gizmo except
Scale Cage (which needs 27 queries). It also removes unnecessary
allocations from two other related vectors used during query processing.

Use a shorter/simpler license convention, stops the header taking so
much space.
Follow the SPDX license specification: https://spdx.org/licenses

- CMake, GNUmakefile
While most of the source tree has been included
- `./extern/` was left out.
- `./intern/cycles` & `./intern/atomic` are also excluded because they
use different header conventions.
doc/license/SPDX-license-identifiers.txt has been added to list SPDX all
used identifiers.
See P2788 for the script that automated these edits.

To avoid that, we simply filter using a debug group.

This might head lead to a crash when a shader uses both ubo and ssbo.

- Fix image.format conversion to string
- Fix warnings about ARB_conservative_depth not found even if GL > 4.2
- Add `array(type)` define for portable array definition

Thanks to the new `ShaderCreateInfo` we now include source files without
any modification. This let us query which are the source files passed to the
`print_log` function. The log will now include a file with row and column
number which is interpreted as a link in most IDE.
DEBUG_CONTEXT_LINES will add more lines around the error lines for more
context. This is also useful if the error line is imprecise (because of
driver bugs) and the reported line is not sufficient to know the location
of the error.
The DEBUG_DEPENDENCIES option will display the list of included files in
the shader sources. Note that it will not print generated source.
This commit also fixes some issues with unhelpful logs, bogus row & column
numbers, other error format, and bug if row was 0.

This is needed by eevee-rewrite

This will be useful when compute shader will be used more.

Detected on `amdgpu-pro` libGL implementation. The workaround is to not
use explicit location for vertex attributes. This is not a real problem
as we don't rely on them for now.

Bypassing the defines which are only there for error checking.

Using opt-in instead of opt-out to make code easier to read.
Add combined flag enum.
Making restrict an inverse flag option because it is so rare to
use it.

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.
|
|
|
|
It came to light that there is no error checking when trying to read
a framebuffer plane without anything attached to it.
|
|
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.
