HLSL Shaders

This directory contains shaders using the HLSL shading language. These can be compiled with DXC using e.g. the included compile.py script.

Known issues

• Specialization constants can't be used to specify array size.
• gl_PointCoord not supported. HLSL has no equivalent. We changed the shaders to calulate the PointCoord manually in the shader. (computenbody, computeparticles, particlesystem examples).
• HLSL doesn't have inverse operation (deferred, hdr, instancing, skeletalanimation & texturecubemap examples), these should be done on the CPU
• HLSL interface for sparse residency textures is different from GLSL interface. After translating from HLSL to GLSL the shaders behave slightly different. Most important parts do behave identically though.
