Hi

I am currently implementing culling that uses D3DXVec3Project to determine wether or not a polygon is on screen based on the 2D screen coords returned. This method requires many calculations to determine wether to draw a polygon or not and thus the speed advanatage is lost to some degree. Does any1 know of any articles that implement culling using VB (Not just theory but code as well) that are better?

I think this a long shot but hey its worth a try

Cheers

Dan

PS I have read up on Quadtrees etc. but without VB code I have no idea how to implement them.
