OK, Cool. Thanks for this, seems pretty nifty, could you explain what
instructions would be involved and how many, I could work out the misc mips
from this. I am aware of the server limitations involved with Polygons (the
amount of area taking up by complex FPU's could be devoted to misc chips and
sdram) and think if this alternative methord is more viable in chip usage it
would be good.

Ahhm, I think that would be good, you sort of lost me there a bit. From the
sounds of it, it sounds simular to a 3D bitmap idea I had. In the idea I
had a compression scheme for eliminating hollow space and from surfaces,
would that help? Given the size of the screen and compaction would a 20-bit
processor be able to do a nice 3D shooter, given 32-bits could more be done?

Ok. It takes not so much from CPU mights.
Octree-based approach needs division by two when descending tree,
multiplication to determine fitting into level-of-detail, scalar product to
get voxel's visual information and one division for projection.
Division could be non-floating point.
Thanks
