Why does this need to be efficient? how many scenes do you have?
aren't bounding boxes for optimisation, eliminating the processing of
what can't be seen, so what you'd achieve is fast processing when none
of the scene is visible!
anyway;
bounding boxs might not be well supported, lower level code, in the
browser and the graphics card might be able to perform the same
optimisation more generally.
The same thing, i think, applies with LODs, but for the browser to do
this generally is more difficult, meaning there should be more
improvment possible by adding these to a scene.
and one more thing;
if VRML things can move, i guess your assuming a fixed scene, but a
general VRML scene bounding box calculator can't exist.
