How Does Octtree work

Post by playerdark »

Ok, this may sound stupid, but I have no experience with octrees, never used anything. I understand that it helps speed up rendering by culling objects that are not visible from a camera position, but how exactly? And more important, what do I have to provide to make it work? Surely there must be more to it than just adding scenenodes with addOctTreeSceneNode ()

I looked around but unfortunately I didn't really find any good newbie info on that topic here or on the Irrlicht website, so I would appreciate any help

Thanks

well, without going into the the technical details of octtrees: it _is_ just using addOctTreeSceneNode().

sadly, the tree is not saved, so it is recalculated each time on-the-fly...
