Subject: Lineal algebra problem



Hi, I am having problems with transformation matrices. Suppose the
camera is in the origin (0 0 0) and pointing to positive "z" (0 0 1).
Positive "x" is at the right and positive "y" is up. I need to move the
camera to a point P1 (the look-from) pointing to another point P2 (the
look-to). Is there a general procedure to do this with translations and
rotations?

Thanks
