# Geometry

I'm having some problems calculating movements in 3-dimensional space. Are there any good, fast, introductionary documents out on the net on geometry in 3-dimensions (Euclidian.)

what kind of 3D geometry, do you mean basic Vector and Matrices math ?
Or some more specific stuff like collision detection ?

Well anything, really, but focus on vectors vould be nice. I've sometimes tried to figure out how to calculate a new position given a starting point and a vector point/reference(??) a desired length. I havent gotten anywhere using plain trigonometry. Also rotating something that isn't level has puzzled me a bit, although I think I'm close to managing that using plain trigonometry.

Well, I could explain it in great detail, but I'm lazy so I'll just give you a link ;-)

Is collision detection easy/feasible in VB? Do you know of any site or book that may help me with that?
