OnPreRender seems wrong

OnPreRender would call registerNodeForRendering to register nodes to the corresponding list for later use. in turn, isCulled is called to try to cull away that node. the camera's tranformation is needed in the isCulled, but, quite possibly, the camera HAS NOT been updated when it is used, this is buggy!

That's right. Another problem is the OnPreRender()- OnPostRender() stuff. I don't like it anymore, one of the methods is definately too much. Will be changed in one of the next releases.

rats, my portal rendering system http://www.irrlichtnx.mmdevel.de/phpBB2 ... .php?t=142 (which I still haven't got around to giving a thorough speed test btw) depends on having both those functions, as OnPreRender is never called for nodes culled by the portal rendering.Oh well, I suppose I'd just have to add a new variable or something so I node would know whether or not it should be culled, while always updating its position.

Also, while we're on the topic of OnPostRender, that function needs some modifying so each node does not have to recompute its rotation matrix and do a matrix-matrix multiply every frame, only if its transformation was actually changed in the last frame
