Looking at the exported obj file it seems that there is the same number of
triangles but their orientation is different. The connection of their patterns
should be the same but I can't say for sure. The inc file is about 200000 lines
long for the model of the woman. 
I say they are all keyframes because in Poser there is no interpolation between
the imported BVH frames. The position and orientation of each part e.g. Right
upper arm is defined by the BVH file for each frame. If I wanted to increase the
frame rate then Poser would interpolate for me.
I posted this animation at 15fps to cut down on size and render time. I need to
use 15fps for the PAE system that calculates the hair and breast movement. If I
were not utterly sick of this animation I would use 30 fps.
Over the weekend I will do a new one using a different motion at 30 fps.
I hope  have answered your query in an understandable way but I'm no expert.

I would be surprised if they aren't the same, because you're skewing the
same character. It's possible that Poser tries to smooth out some joints
after you have applied the BVH motion, thereby making interpolation
troubleful.

Have you seen:
http://news.povray.org/povray.binaries.animations/31438/

I must say, that even if it works and POV-Ray can interpolate the data,
you'll need a few hours of manual work to prepare the files to be read by
the macro I've written in POV-Ray. It's easy, but takes some time because
you have so many keyframes. At the moment, there are unfortunately no way
for POV-Ray macros to work directly on data encapsulated in a mesh2 file.

Hugo

I have now:-} I tried blender and did not like it. I've never gotten into making
my own meshes, not enough hours in the week :-{ Kitsune_e 's animation is cute.

IIt sounds interesting maybe useful for other projects. I've found a workaround
for having to convert to 15 fps then back to 30 fps so I'll stick to what works
for me just now. One of the problems with Povray projects is that I keep having
to learn new programmes and techniques. No problem with that but it's so
distracting and time consuming going off at tangents. (Must get back to Fractint
someday, I only "looked" at Povray so I could draw fractal landscapes Ha! This
programme should have a health warning - Can become addictive)

very nice work

Im not sure what is involved with this type of thing but the end product is
very good.

Keep up the good work ;)

I'm glad you like it but the process is very mechanical.
Create an animated figure in Poser the export the series of meshes. Convert the
meshes to, in my case, UDO's so I can build a supporting scene in Moray. Export
to Povray then tweak the Povray code to use a different mesh for each frame. The
textures of the model come from Poser.
Now that I've worked out the technique I find the application limited due to 
A)	the unvarying motion of BVH files. I mean they are difficult to modify
and you are stuck with what you can find on the web.
B)	my poor Poser expertise. 

I think it has been a worthwhile  project but its time to do something
different.

Onwards, outwards and upwards!	Space-cadet.

Nice work!

But in ballett, if you do a thing like that, you should
stretch your right leg far out when in front of you.
Just a little hint.

Keep on working. Great success is near. :-)

You must have missed an earlier part of the thread. The models movement is from
a BVH file where a live actor has sensors placed on their body and the movement
is recorded. Therefore changing the motion becomes a Poser skill. I got put off
after working on an animation posted as Hiwire (?) and will not be continuing
this sort of thing any time soon :-{
Thanks for the comment though as any encouragement is appreciated.

Jup, I must have missed it. Did it was a kind of motion capturing?
Motion capturing is a good way to copy the movements of a real
person. But for me it sometimes looks a bit too static. After capturing
the motions must be edited to smooth them. Have you seen
"The final flight of the Osiris" of the Animatrix-series? There they
proofed that motion capturing can look very good.

Well, I haven't done anything with POV-Ray for long time. I think it
is time for me to get to work.

Yup, "motion capturing" that's the phrase.

Tell me about it! :-}

No, I'm not a great movie fan. I posted another motion capture animation here.
http://news.povray.org/moray.binaries/29025/
It was my first attempt and the textures and props are poor.

Who am I to disagree? :-}

I don't know that much about the workflow but you can read a bit
about it on this site:

Hey that one is quite cool. I think its Capoeira (Brazilian Martial Art)

I think I should also work a bit more with Poser.
