Hi
Is it possible to write custom shaders from scratch with Pov-ray`s language? Is
this something that can be done only by patching the code base?
thanks

Some typical shader effects can be achieved using POV-Ray's various
patterns, most notably the "aoi" and "slope" patterns. Others can be
achieved by smart preprocessing (e.g. proximity patterns). POV-Ray does
not provide a dedicated shader language though, so for some cases it
might be necessary to get your hands dirty on the source code.

clipka, thanks for your answer. I was thinking about writing things like simple
specular shaders, minneart shader etc for tests.

there used to be an unofficial version of POV-Ray, I believe it was
called POVMan, which allowed you to use Renderman-shaders in POV-Ray.
If it still exists, it's probably hopelessly outdated by now, but still,
it might good enough for you.
Let's see if I can find an url for you... nope, seems to be gone. But I
might still have the installation-files somewhere, let's see!
hmm, can't find it, sorry :(

Incredibly enough people keep snapshots of the internet around ;)

Also, the living net still seems to have something on the clothray page
