You need to have the planes of the frustrum looking inside (their normals must point to the center). Then the rendering discard can be done by checking if the object is completelly outside of one of any of the six planes of the frustrum. You can do that with a sphere or with a AABB, or any other container where you can calculate the distance (and the side) to the plane.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
