vector and matrix math


    Jan 30 2006 | 2:41 am
    with all this talk of 3d coordinate transformations, i was reminded
    how much i forget my basic linear algebra. i don't think i've touched
    an identity matrix or dot product since 10th grade..
    does anyone know of any good resources or references for learning/
    relearning this stuff? actually, what i'm most interested in know is
    why it works, not just how to perform certain operations. i already
    have the red book, but it doesn't seem to go into much detail about
    the math and the whys.
    thanks!
