Hi! I'd like to have a way to detect if a body is visible on the screen or not (ie if it is behind the camera, or far too distant from it).
I have the body as a mesh, from wich i can eventually get the bounding box.
I have the camera position and the LookAt point (as in gluLookAt).

What algorithm can i use? It doesn't matter if it's not 100% precise.
If you have something premade and ready to use, all the best
