Hello, I would like know how do to know if an object is in the camera field, for instance, I've my object behind me, so behind the camera and not in the camera field, how detect if my object is in the camera field or not (with code, not with eyes ^^).


Thanks a lot.

This will be a pain and a half, the only way to do this is to create a View Frustum Culling method, not only that but you'll need to create an Octree (useful for other stuff like collision) if you want it to run fast when object count is high. All are say is your not going to have fun learning this one. Google 'View Frustum Culling' to learn about it.

A dream is a fantasy, if you achieve that fantasy it was never a dream to begin with.
