Linear Algebra, Matrices, and 3D math

I realize that it appears that I have not made any real progress on this game for some time now.  I'm finding that there are many principles that I need to learn before trying to tackle 3D.  Part of that is math, which I have been struggling through for a little while.  I highly recommend that anyone who is interested in doing anything 3D learn about linear algebra.  A brief explanation is that it is the math that helps give the illusion of 3D on a 2D surface (like your TV or monitor).  Anyway the learning process is slow as I'm not as young as in times past.  As I have said before this will take a long time, especially since I want to do it right.
