I have been trying to figure this out for a while. How can i tell if a
bouding box is in the view frustrum. I know how to tell if a point is
infront of a plane…but how can you tell if the whole bounding box is
infront of the plane? Right now i am just checking if the corners of the
box are in the plane…it works but isnt accurate enough. Do you have
any information on the subject??

Hope that helps.
well, i am just checking all vertices of the box against each of the 6
planes of the view frustum.
if all vertices fall on the outside of a plane then the whole box is
that means if even if all vertices are outside the frustum the box
still may be visible.
this is one of those situations where only one thing can help: PAP,
Pencil And Paper.. and a bit of creativity..
this is a good situation to learn to solve problems yourself..
then again, some dude called marc wrote a great frustum culling tutorial
once, with code.. dunno what his surname was, thought.. and don’t have
the link anymore
I ended up culling entities by bounding spheres…It worked out pretty
good. Allthough it is accurate enough for my entities….I am going to
need to use bounding boxes for culling the quad trees. I am just going
see if i can figure it out. Thanks :) :yes:
