I am working on a 3d engine and I now have to deal with culling. I plan on doing this by testing to see if an objects bounding box is in the view frustum, to do this I need to figure out how to create the 6 planes of the view frustum. I am using directX 8, and I have a view matrix and a projection matrix. How do I create the view frustum planes? Once I have the 6 planes of the view frustum how do i check to see if an object is within the planes? Go on an Intense Rampage

There is a link to an article at
