I waited for about half a minute - 48 seconds were required in fact.
So we have:
standard POV: 6s parse + 59s trace
your kd-tree: 48s parse + 60s trace
Since scenes containing a lot of small objects placed on the surface of
a large object are very common (any landscape with plants, houses, rocks
etc.) i think this is a major problem. In a large size render the parse
time difference will of course not be so important but it would not be
possible to really replace the existing technique with your system with
such a difference.
Also note that in this scene the memory use difference is 186Mb with the
kd-tree vs. 27Mb with standard POV!
