these are a few of my test fly-throughs I made using
a combination of Imagine 1.1, Rayshade 4.0, Jpeg 3.0 and
some simple C code. The images are not in ANIM format, but if you have a
programming language handy (I'm learning Arexx now, and I might have
a program out soon to do this chore in Arexx) you can decompress and
piece the animation together easily using format statements and system
calls. That is how the animation was created in the first place.
I believe that all Amiga aniations should be done somewhat like this
because of these reasons:
+ Its easy to implement.
+ Animation making utilities are available on most machines to piece
frames from several formats together.
+ JPEG 3.0 supports 4 formats which are common to all platforms.
+ The code to automate making the animations from jpeg files is
very easy to write.
+ Since JPEG 3.0 supports quantization of colors and different dithering
patterns as well as pseudo-virtual memory, it is easy to configure the
animation to be displayed on any computer no matter how much memory
the computer has. However, if the animations created are
larger than memory will permit even on 8 colors as 320x200,
then the animation should be split or displayed with some
special direct-from-disk animation displayer...
+ Plus it is very very small. One of my animations is 320x200 in 24-bit
color and 100 frames, this comes to 600K if compressed with a
quality of 80 on JPEG 3.0. Almost as good as MPEG, right?
