Watching system monitor on my win98 machine was quite frightening! You
do realise your scene contains 3.2 million cubes at level 5?
Each level uses 20 times as many objects as the previous, level 4 has
160,000 and used 374 megabytes of ram.
3 suggestions come to mind, neither particularly helpful:
1) Stick to level 4
2) Upgrade to a 64 bit machine with gigs of ram
3) Most of the cubes will not be visible. Maybe they could be removed,
but that could then affect the radiosity calculations.
I expect that to be a non-trivial exercise, and better suited to a
recursive macro method of scene generation.
If you didn't want the gaps between the cubes I'd suggest starting with
1 solid cube and cutting holes through it with a recursive macro (I like
recursion!). That would scale by 9x the number of objects per level
instead of 20.
