These are intended to be simple explanations for the high-school math level persion. There are, of course, omissions and simplifications. That's fine. The purpose of all of the tutorials here is to enable people to learn graphics programming and give us more cool code and programs. Since many of the best coders out there haven't got much college math under their belts, (and I'm not convinced anybody understands most of what they do have), I figure if we can reduce the concepts down, the readers will have a true concept of what's going on, not just a manipulation of the symbols.
Submissions gladly accepted.
Other resources: Haven't had a chance to look very far yet, but Programmer's Heaven seems to be building a big database of links and informed me of some technical problems with this site, so they get a link.
