Just for the heck of it, I took the TrueSpace .cob file for the Gila monster
I used last round in the IRTC and converted it into a number of different
formats.  Here's how they compare in size:

Strata StudioPro (.vis)         1.29M
3D Studio          (.3ds)        1.35M
TrueSpace         (.cob)        1.88M
Imagine              (.iob)         2.64M
DirectX              (.x)            2.75M
Renderman         (.rib)         3.64M
VRML               (.wrl)         4.67M
Wavefront          (.obj)         5.04M
Renderware       (.rwx)         5.54M
AutoCAD          (.dxf)          6.04M
Alias                   (.tri)           7.40M
OpenGL C code (.c)            7.68M
QuickDraw 3D   (.3dm)        8.13M
stereolithography (.stl)           11.8M
POV                   (.pov)        12.6M
Pro/E                  (.slp)          16.8M
Lightscape           (.lp)           19.1M

Interesting - is the quality on each fairly identical?

  How much does it take when converted to the PCM format?

Would the POV file be smaller if there was no white space?  When I type into
CodeMax in POV-Ray's windoze GUI, tabs are converted into spaces.  This can
be changed by pressing alt+enter and finding the check box that changes the
opinion on the language/tabs tab.  The spaces take up more disk space than
tabs.

Good question.  I know that the TrueSpace file, the 3DS file, and the POV
file were very similar, but I can't say for sure about the others (I don't
have all the software to do the renderings).

I'll have to check on that one tomorrow.  I'm not sure if the software I'm
using will export to PCM... actually, I'm not familiar with the PCM format
at all.

You will have to use Warp's Mesh compresison utility to achieve the .pcm
format.

Ah-hah.... I have been to that site.  I've been meaning to check out the
hair growth macro that comes with the compression utility; the example pic's
look pretty good.  I'll check it out when I get home from work tonight and
post the results tomorrow.
