I need algorithms to convert from world coordinate system to a eye
coordinate system.  Given a vector in world coordinates that specifies
the z' axis, how do I convert points expressed in the world
coordinates to points expressed in the coordinate system defined by
the given vector.  My problem is two-fold: 1) how do I find the x' and
y' axes given the z' axis (left or right handed), 2) how do I
transform the points once i have the new axes.
