(...) Well, I know where the camera is, and I can create vectors from the camera to both end-points of the conditional line, and to both control points. I'm pretty sure that the calculation could be done with just this information. However, I'm not (...) (16 years ago, 14-Dec-08, to lugnet.cad.dev)

(...) Is there some 'easy' way to determine if the control points are in or out of frustum? Is there any other way to transform points, without considering the frustum (Well, obviously there is at least one, but it's the long way of calculating the (...) (16 years ago, 14-Dec-08, to lugnet.cad.dev)
