AniVision is still being developed. More docu and explanation will be available here once a first public beta version is published.
Meanwhile the animation description grammar and the POV command comment grammar are available.
Here is a sample AniVision source file (the one which I am currently using for testing).

Currently, there is only a tech preview for those interested available.
But be warned: There is really little you can do with that. Only C++ programmers may have fun with it. Please send me comments and suggestions if you tried it out. But don't send me complaints if you can't get it working.

2004/03/20: Flying along Vallis Marineris

The first serious film was rendered: Flying along Vallis Marineris on Mars.
There is a little making-of to show how things were done.
NOTE: Do not expect that you can do much more with the current version of AniVision (0.3.5) than presented there.

2003/12/21: First film rendered!

But don't expect anything exciting. It's just a proof of concept "moving object over checkered plane".

Of course, only the source code is available.

Requirements:

• The devel platform is linux-ix86-gnu, others may or may not work. Other Linux-gnu platforms should work, though.
• In order to build AniVision, you need a recent version of GCC (>=3.2 will do), as a developer you also need recent versions of flex (>=2.5.31) and bison (>=1.875).
• AniVision depends on HLib. You will need to compile HLib-1.0.0 prior to compiling AniVision (and not 0.9.9g or earlier).

Source:		anivision-0.3.5a.tar.gz   [555kb gzipped source tarball]
Version:		0.3.5a   (2004-05-22)
Author:		Wolfgang Wieser   (report bugs here)
License:		GNU GPL (Version 2)
Requires:		HLib-1.0.0

Here is the previous version in case you cannot get the current one running:

Source:		anivision-0.3.5.tar.gz   [552kb gzipped source tarball]
Version:		0.3.5   (2004-03-25)
Author:		Wolfgang Wieser   (report bugs here)
License:		GNU GPL (Version 2)
Requires:		HLib-0.9.9g

Build: First, build hlib as described in hlib's BUILD file. Do not install hlib, just build it in a dir called hlib-build. Then, unpack the AniVision tarball so that the anivision-0.x.y dir is on the same level as hlib-build. Create a build dir called anivision-build and from there run configure as usual, followed by either
make ADDFLAGS="-fmessage-length=$COLUMNS -g -O0 -Wno-switch -fno-omit-frame-pointer" all
...or...
make ADDFLAGS="-fmessage-length=$COLUMNS -O2 -Wno-switch -Wno-inline" all
Then, run make check_core with the same ADDFLAGS= passed to get an idea what is being done...

Good luck.
