PovClipse is an eclipse editor plugin for Povray (Persistence of Vision Raytracer) scene- and include files. It features syntax highlighting, code folding, code assist, outline view as well as running Povray or MegaPOV using render configurations.
Well just a raytracer in Visual basic 6, thus the name VB6 raytracer. Not because it is easy or logical, but because it is hard. I know this is not the right language to write a raytracer, see it as a stubborn POC that it is still somehow possible.
