Welcome Dave,
What you want to do is possible. Look in the documentation for
trace, but be warned (gently) that this is an advanced feature. I am
sure someone better versed in Pov-Ray SDL can answer you better.
As for a scripting language you are in luck, Pov-Ray's scripting
language is called SDL, see the document section 3.2 Scene
Description Language and have a look at the tutorial 2.3.10 SDL
tutorial: A raytracer.
Are you using a modeller to create your scene? And if so it is a very
good idea to stop for a moment to become familiar with SDL.
