    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?

    Thanks.

    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.
