you could set the initial bounding box to infinite size to force
initialization in the first frame and set the real bounding box at the
end of initialization.

For this type of generated geometry I'd suggest either a conservative
guess for the bounding box. If even that is not feasible one could test
the generated geometry inside rendeEnter against the frustum and not
render it if it's outside. Of course, the time for computing the geo is
already wasted at this point.

Thank you for considering to contribute it. I guess it could either
become a contrib library or moved into e.g.
System/NodeCores/Drawables/Misc and become part of the system library.
Thanks,
Carsten
