[comp.sys.amiga.graphics] Sculpt 4D Dynamic HiRes Anims

payotte@nro.cs.athabascau.ca (Paul Ayotte) (03/19/91)

With the ability now to take 24 bit Sculpt 4D pics and convert to dynamic
hires with Art Department Pro. I would like to hear from anybody who has
managed to make a animation either from a Sculpt Anim or somehow joining 
a
series of sculpt images together to make a anim. Any suggestions on how 
to
do this, preferably with an anim 'assembler'. <--- bad choice of word.
Anyways mucho thank yous to anybody who can help.

I doubt there is any such animal.  The Amiga is working "overtime" just to
handle a *still* dynamic hi-res picture..640*400 image in 4096 colors.  
DCTV has its own file format and can display full NTSC color.  You convert
hi-res 24bit images to DCTV proprietary format which is close to hires
IFF (except with DCTV "magic code" ntsc information in the first two top
scan lines)..anyhow you can then use the public domain utility MAKEANIM
to string a series of these ostensibly hi-res images togeter to create 
quite an impressive piece of animation.

I think you'll find that making animations in dynamic modes is improbable.  In
order to change the color palette ever interlaced scan line, dynamic modes use
both the copper and the processor 100% of the time.  This means that multi-
tasking must be shut off.  As such there is no processor available to decode
the next frame of an animation.  If the images are already in memory (limiting
greatly the number of frames) it might be possible, but the added overhead is
most probably too much for a 68000 machine.  It might be possible with an
accelerated machine (or 3000) but even then it would be tough.

SHAM images utilize only the copper and can change the palette every other
interlaced scan line (or every non-interlaced one), and that may be a 
reasonable format to attempt animation in, but I don't know of one yet (BTW,
overscan makes even SHAM overhead prohibitive, not for the processor but for
the memory bus).
