While at the AmiExpo in NYC, I picked up a copy of Sculpt 3d from the
Byte-by-Byte booth.  They didn't have Animate 3d ready (is it now?) yet,
but I was pointed to a user's group booth where the people from BbB had
just released a PD page-flipper-delta-compressor animation thingie that
had been used to create the Sculpt 3D demos (rocker, kahnankas - the
BADGE animations).  I've been playing with this stuff and have had a
couple of problems (I hope they're really stupid ones, and I can get on
with it) with the program (DILBM) that diff's two images and creates a
delta file from them:

a) It only seems to work if the source ILBM files are on real (not RAM:) 
   disks. I have 2.5meg, so I don't think I'm running out of memory.  Does 
   this make any sense?
b) Here is the real problem.  DILBM doesn't seem to be able to create
   a delta if the two source files have different color tables.  Since you
   don't have any control of the color table that Sculpt gives an image, this
   seems to rule out any interesting animations (a big purple gizmo suddenly
   appearing in an otherwise yellow scene).

Has anyone else used this package? Any luck? Thanks.
