Have you had a trigonometry course yet? If not, a quick search of
the internet turns up plenty of links. This one looks easy enough.

Then you'll probably need to read up on matrix math.

And then finally it's on to "transformation matrices" which combine
trigonometry and matrices. There are about a million links on the
internet for this so you'll have to decide which you like best. You
may also want to search for "homogeneous transformation matrices".
LDRAW.EXE apparently doesn't use them, but they make things a bit
easier for me.
Good luck,
Don
