I am accustomed to thinking about projected matrixes as having x,y coordinates, relative to the jit.window. Objects tracked by the camera also have x,y coordinates, so it is easy to detect if the tracked object is in the space of the projected matrix.
I am having trouble thinking about how to apply this to either rotated matrixes, videoplanes, slabs or gridshapes. I guess there is probably an expression that I could write, which will take rotation into consideration.
I'm sure I will figure this out soon, but I'm hoping to find a simple efficient solution, and examples or suggestions would be great.
