I am looking to hide / show nodes laid out in a grid and could use a push in the right direction. I currently don't even know what question to ask.
assuming I have a grid of nodes laid out in a x/z grid it seems that if I know where the camera is, what direction it is facing and what the camera parameters are, I should be able to hide noes that are not visible and only show those that are.

any help is appreciated.
object paging system
Re: object paging system
That's what Irrlicht does when you enable culling for nodes (ISceneNode::setAutomaticCulling). EAC_FRUSTUM_BOX would be the one that tries to regard the camera. Note that this function did have some bugs until recently (got patches around 2 months ago in svn trunk branch), although I think it never hid too many, just not enough sometimes.
