I am working on a project involving some 3d programming (in AutoLisp), and have managed to muddle through with what I remember of university geometry. I run into basic geometry problems (i.a.: find the 3d point where 2 lines intersect, given only the start points, angles and slope of the lines) which I manage to laboriously and clumsily solve. I'm sure most of these problems have 'canonical' solutions, worked out by graphic programmers. Is there any online resource for algorithms and formulas for typical 3d programming problems?
A good, simple explanation of the theory (and application in 3d graphics) of transformation matrixes would be nice, too.
