Function Documentation

Vec4 cross (  Vec4  v1, Vec4  v2 )

Cross product operator. Calculates the normal vector to the plane described by the input vectors. Sets the fourth cell to zero as a cross product will never be a point. Parameters: v1  Input vector (3D). v2  Input vector (3D). Returns: vector to complete right hand frame (or whatever).

float dot (  Vec4  v1, Vec4  v2 )

Calculates the dot product. We're ignoring the fourth cell for the moment. However, if code is written carefully enough, then it may be included again.
