Mathematics for Computer Graphics, 2nd edition, by John Vince. End of Story. Best intro book on the subject you can get if you're starting from near zero.
Pre-Calc for dummies is also pretty decent for a less CG-ish, more general easing into maths. It's meant for high-school going to college refreshing students memory or covering some gaps, but it's well laid out to get a quick once over of many things people were taught but never learnt, or simply don't remember. I've had unanimously good feedback from everybody I trained who bothered to write about those. On Mon, Apr 8, 2013 at 10:11 AM, Sam <sbowl...@cox.net> wrote: > You are most likely correct on that.
