Anyone know how to obtain the vector that points along the eye direction
(perpendicular to the screen)? I know it in there somewhere, but where.
Could I take two points in the view system ( say (xcenter,ycenter,1) and
(xcenter,ycenter,2), where [xy]center is the center of the viewport) and
inverse transform and then subtract them to get the vector? Is there an
easier way?

Thanks in advance,

Bill Volz
