## HLSL Shaders

This directory contains shaders using the [HLSL shading language](https://docs.vulkan.org/guide/latest/hlsl.html). These can be compiled with [DXC](https://github.com/microsoft/DirectXShaderCompiler) 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.
Add shaders re-implemented in HLSL These were written against the shaders at revision eddd724e7. There have been changes made since then, which will need to be mirrored. See `data/hlsl/README.md` for the current status of each sample. 2020-05-21 10:20:19 +00:00			`## HLSL Shaders`
