Using sample Motion Capture files from Stephen McAvoy, I've just finished writing a
program to convert BVH files to POV. Using my program, I can take a BVH file to an
MP3 file in about 15 minutes.
It only creates simple stick figures for the model, nowhere near what Stephen has
done with Poser. However, I've designed it so that I can add better modelling to the
POV file after it's been converted from the BVH file. I just haven't yet.
After the POV files were created, the only manual adjustments I made were to the
height of the ground plane, and the camera position.
I'm still trying to figure out how to get this kind of data to work for my existing
models (see "Counterforce" at the bottom of
http://www.irtc.org/anims/2002-01-15.html )

MP3 ? Everyone thinks mpeg layer 3.
There are some flickering in the movements. Are these present in the
original bvh file as well? Otherwise neat!

Hugo

No, there was none when I looked at it in Poser. I've found that it is common
for some flicking to occur in the files I've looked at and it has to be edited
out. Tom's work is much purer Poving, the animations I posted are IMHO
superficial. I'll append an avi of the first 120 or so frames rendered in Poser
for comparison.

Stephen

You're absolutely right. That was a typo on my part. It should have said MPG.

After looking at Stephen's Skeleton using the same motion file, and the Ballet20
(which I haven't posted due to size) it's clear that my generated pov file is in
error. I'll post again when I have something fixed. (I suspect it has something to
do with LHS vs RHS coordinate systems)
