A’right, I spent a good part of my weekend working on this, and progress is… embarrasingly low.
Basically, I define a segment as a base (x,y,z), and a vector (x,y,z). Working off of the vector’s orientation to the base, I’m trying to rotate a polygon in coorespondence.
I’m a’right working with two dimensions (working with just XY or just ZY, for a specific example), but once I try… well, three of them (^_^)… I run into terrible trouble.
I’ve yet to find a good “getting to know all this 3d trig” site (or tutorial, etc), though I’d assume they’re out there. Any advice to push me in the right direction?
