Understood. This sort of linear interpolation isn't too hard (a lot easier than projecting a 3D triangle into 2D, where you have to take perspective into account). But I don't know of a good explanation offhand. Might make a good RBD article. > I'd also like to learn how to write a ray tracer too. I can certainly respect that -- in fact I've done it once or twice, for the same reason. My ray tracer was ridiculously slow compared to, say, POV-Ray, which has been optimized for years. But it did demonstrate the basic principle of how they work. Again it's a little hard to explain in an email, but an article with diagrams and sample code should make it clear. In the latest issue of RBD, the editor (Marc Zeedar) invited readers to request articles they'd like to see. Maybe you should drop him a note.
