Hi, Dear all,
When I recently used opengl to write a compute shader(use version 430, not 450 or 460), I encountered a compilation error as follows:
ERROR: 0:50: '' : cannot use layout qualifiers on a function parameter
ERROR: 0:50: '' : compilation terminated
ERROR: 2 compilation errors. No code generated.
Part of the shader code is as follows:
#version 430
#extension GL_ARB_shader_image_load_store : require
layout(binding = 0, r32ui) uniform volatile coherent uimage3D voxelAlbedo;
layout(binding = 1, r32ui) uniform volatile coherent uimage3D voxelNormal;
layout(binding = 2, r32ui) uniform volatile coherent uimage3D voxelEmission;
void imageAtomicRGBA8Avg(layout(r32ui) volatile coherent uimage3D grid, ivec3 coords, vec4 value)
{
//do something.
}
void main()
{
imageAtomicRGBA8Avg(voxelNormal, position, normal);
imageAtomicRGBA8Avg(voxelAlbedo, position, albedo);
imageAtomicRGBA8Avg(voxelEmission, position, emissive);
}
This means that the function can not use layout(r32ui). But in Nvidia card, It can work fine!
How can I deal with this problem? If you have any comments or suggestions, please let me know.
This is the demo:

If you use vs2022, there is a small issue in the code, you need to add a header file in scene_cameras.cpp like this #include <iterator>.
Thank you!
