Getting the EXACT viewfrustrum

Hi, i need the EXACT viewfrustrum, for culling, of course.
I retrieved the frustrum once by taking the up/down-FOV (45°) and calculated the left/right-FOV (60°) and then created the frustrum, but it was too small.
So is there another method to get the exact one?


Hi !

There are a number of ways to do it, on Kenny Hoff’s website (I don’t have the URL but you should find it on google easy) has source for it to, also a search for “view frustrum culling” on google should give you a lot of info.


You can find a link in my page on frustum culling…

I dont give you the link directly 'cause I dont know it of the top of my head.
