Description
Calculates the cross product between two TPoint3D objects.
This function returns a TPoint3D object. The cross product between two TPoint3D objects is defined in the following example:
pointReturnValue.X:= (aPoint1.Y * aPoint1.Z) - (aPoint1.Z * aPoint2.Y);
pointReturnValue.Y:= (aPoint1.Z * aPoint1.X) - (aPoint1.X * aPoint2.Z);
pointReturnValue.Z:= (aPoint1.X * aPoint1.Y) - (aPoint1.Y * aPoint2.X);
