Description
Computes the pick ray vector.
The pick ray vector is used when selecting 3D objects using the mouse.
X and Y represent the coordinates from which the pick ray vector is calculated.
AProj represents the projection.
RayPos is the position of the pick ray vector, and RayDir--its direction.
