Thanks for the help! Sorry it took me a while to get back. I ended up figuring the problem out, turned out he had presented the question in a confusing manner in which we though he told us that we didn't know another point on the plane, just the normal. What he really wanted was for us to assume...
I'd like to be able to deduce it myself, but since I've been stewing on this for too long, a full answer would also be nice. I'm new with vectors, never really used them before. When working in 2D graphics I only used equations for the lines, but the course I'm taking in 3D wants us to use...
Ok, I've been stewing on this problem for a couple weeks now, and it's primarily due to my lack of practice with vectors, but I'm learning how to work with 3D computer graphics and trying to determine when an object hits a plane. Given the normal of the plane N=[nx,ny,nz] and the point at the...
