Frustum tracing means that the primitives of occluding objects are ray-traced from the light’s point of view to form a shadow on the receiving surfaces. It is a form of ray tracing and, as such ...

I'm looking for an algorithm that efficiently determines whether the box and the frustum intersect.<BR><BR>The simple cases: If one or more of the bbox's corners in the frustum (i.e. the signed ...

My understanding was that glFrustum and gluPerspective were interchangeable, but after a frustrating 2 days, I know empirically this isn't the case.<BR><BR>gluFrustum allows me to set the ...
