I use OpenGL to do the projection/camera transform. I use the following code to setup the projection matrix:
right = sin ( (double)vp->FOV/2.0 * M_PI/180.0 );
top = right / aspect;
bottom = -top;
left = -right;
glFrustum (left, right, bottom, top, znear.value, zfar.value);
How can I calculate my frustum planes according to this?
Thanx in advance.
Mike
