Detailed Description

a simple grid like space partitioning. the grid cell size must be given in lenght units. after addition of nodes, the first render call invokes balancer which center spherical cells on the paritioned nodes.

currently used for the VisLog which places many nodes on a large plane.

[package, virtual]

implement this to actually render this node itself. also used to update a node's state.

things not seen also do not update. this is sometimes akward, sometimes useful, eg. a movie not seen does not advance
