Given a three dimensional triangular mesh M, composed of irregularly sized triangles, is there a program, plugin^{1} or algorithm that will create a new mesh M' with the same overall shape as M but with regularly sized triangles (i.e.:all triangles having similar sizes)?

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.

I need to create some charts (as in bar-, pie-, etc.) for a presentation. I have used Excel (easy but boring), Illustrator and Freehand (slightly more complicated and exciting) for this in the past, but want to expand my repertoire. Are there any really snazzy looking, easy to use charting apps for XP? [more inside]
