Yes to write a new shader but what about implementing a shader
interpreter/caller in POV-Ray.

Does that mean you need a compiler that will generate the actual CPU/machine
code (platform dependant) for the shader or do you have compilation built into
the renderer & it compiles the shader as an initial stage in rendering.

I thought that shaders were interpreted (seems unlikely now that I think about
it - way too slow)

How do shaders work anyhow.?

Does anyone have the zip/tgz/? of that patch that I mentioned.
