From what I can see this is comparing shader languages weighing pros and cons. To use an analogy. Think of Vulkan, Metal, DirectX 12 (DX12) as different database engines. They run compute/render shaders which are incompatible dialects of each other (like Oracle SQL != Postgres SQL != MySQL). WGPU tries to be the ANSI SQL. This an oversimplification ofc. Today most shaders compile to an intermediate form Spir-V which then targets different backends and can lead to some funny translation. > GLSL/HLSL/MSL -> SPIRV -> WGSL -> SPIRV -> GLSL/HLSL/MSL See https://github.com/gpuweb/gpuweb/issues/566 https://github.com/gpuweb/gpuweb/issues/566
