We now want to restore FFP support in the renderer. The benefits are:

  1. Possibility to use RTX Remix with it, which will add raytracing support (RTX Remix support #1314).
  2. Possibility to port it to OpenGL (OpenGL Renderer #280), so it can run on even older GPUs and about anywhere.

I wonder if clouds can be replicated using DirectX's volumetric fog or something. Here's an article for OpenGL that shows how to do it without shaders but we can probably replicate that for DirectX.

https://vvise.iat.sfu.ca/user/data/papers/clouds.pdf

That's a very simple example with a bounding box. Another algorithm that is more advanced seems to be using a particle queue:

Here's another library of tutorials and fixed pipeline algorithms we can use to help us with the fixed pipeline renderers:
