Thanks for that article.
Ack that does add quite a bit more processing! So i guess checking all frustum corners to see if they are within my sphere bounds would be the equivalent?
I also do AABB culling, i'm using the AABB pn-vertex optimization (mentioned in the Lighthouse article), not sure how it would work in this case (not sure how to get the pn of a frustum as I could with an AABB).
Has anyone attempted doing something like the pn-vertex optimization for proper large AABB to frustum checking?
Any semi-optimized (like pn-vertex type things) implementations out there?
