   Octree on an animated scene
  I have an animated scene hierarchy (i.e. scene graph), which I plan to cull with frustum culling. How can I generate an Octree that remains current?Obviously building an octree each frame cancels any benefit. Could I move nodes between leaves? or would that leave discrepancies. Maybe I could regenerate only child octree nodes that have had an animation occur within them AND the animation causes the node to leave the leaf. An Range required to alter structure member could be associated with each node maybe?Cheers, JPulham.
