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.
