Re: [Plib-users] cull and draw

[Tony J. <ton...@ya...>]

Hi Steve,

Thanks for the quick response.

Does the answer depend on the size of the world ? I was thinking of a =
large world where there might be a lot of detail/models in the next =
valley etc that you might not bother to draw. Or does the overhead for =
occlusion culling scale with world size in such a way as to still make =
it not profitable - and better off looking for another solution ?

  It only culls to the view frustum.  For outdoor applications, =

  though.
