I have created a rotation matrix for a specific polygon on a given object. I would like to now determine if any other point in the scene intersects that polygon.
My thought is that I can convert the point in space in to the local coordinates of the rotation matrix and then determine if the z axis is at 0. THis, in theory will determine if the point has intersected with the polygon? Right?
If this is accurate, my question is, how to I convert the coordinates of the point in to the local coordinates of the rotation Matrix?
Thanks for your help.
