v0.3 has a separate recurse for bounding volumes updates. Eberly (3D
Game Engine Design) recommends performing bounding box checks when on
the way back up the rendering recursion. Is this an option?
In 0.4 graph traversal is done much more flexible, ie. you have various
kinds of traversals. This is done like that because first the design is
cleaner and easier to enhance and second it can be better optimised on
multi processor systems. BTW you cannot easily perform the bbox update
while traversing upwards because the app might change the graph
afterwards (before rendering the next frame) - or do you think of sth
different here?
And I dare to say that the 3DKit is not aimed at games, in games you
need a highly tuned, specific implementation, so the 3DKit is more
designed to serve visualisation, modelling and research needs.
