It's not always easy to port shader code to POV-Ray script. It can be done, but
things often have to be nested in a funny way.

I hope a future version of POV's SDL more closely resembles GLSL or other
languages, and gives us more access to lower-level data. At the very least, I'd
like to have proper swizzles and maybe a unified approach to definitions (the
function/macro divide is huge sometimes).

I'm not familiar with Martijn S. but I know about IQ, having been into shaders
for a while now. He seems to have developed a good number of functions and
methods for doing things, and even maintains a site where we can learn all about
it. Sometimes I wonder if raymarching might not just surpass triangle rendering
at some point for games and film. Maybe not, but it is more flexible in certain
ways.
