How was this done? One mesh per frame? How long was the animation? And how
much disc space did it take?

Would it have been possible to make the horses run over a height field and
other such demanding interactions with the surroundings?

With the feature I propose combined with the right macros, it would be
possible to animate characters using POV-Script, just like other things can
be animated in POV-Ray.

And yes, I *do* believe quality character animation can be done writing
numbers in a text editor. With the proper macros of course.

And very few people can model anything at all that way. But lots of POV
users can. I don't think you should underestimate them.

GUI is fine for some, but not a necessity.

People use it to model, so it is a modeller.

I'd like it to be a character animation program too.

No, a capability for deforming meshes in a certain way.

It could be used for bending, stretching, lip-synchronization, boning, and
many other things. The way I've proposed it is rather general.

I feel that way too. Well, thanks for your understanding...

What's the difference?

Well, it's a matter of definition I guess but I choose not to call it mesh
data manipulation since the mesh data (in the file) remains constant. "Mesh
data manipulation" leads my thoughts to changing the written mesh data,
which it is not what happens. But of course all computations involve
internal manipulation of data but that's needless to say.

I'd like to see some sort of boning features available for the meshes
I use with POV, and I don't even do animations. I'd like the ability
to accurately deform 3rd party meshes for still images. 

Of course I *could* buy Poser, Rhino, or any one of several other
commercial 3D packages, but POV-Ray is free. It would be terrific if
there were some sort of practical way to accurately deform meshes
(boning comes to mind in particular), without spending a lot of money
on some external modeler.

Later,
Glen

I think it's a good idea, considering there are so few Pov animation entries on
IRTC. It might just help to get more animations on there.

I don't know the technical details of the best way to implement boning
in meshes, but I would definitely like to be able to use meshes with
bones in my renderings. I'd love to be able to deform and tweak
meshes,  instead of using them as static objects, as I do now.

Later,
Glen

Just like to point out that deforming meshes (meaning translating the
vertices in a certain defined way) is really not much problem in current
pov/megapov.  Just define a vector field in a user defined function or
pigment and use it to translate the vertices.  It will work like displace
warps for patterns.

I haven't used any character modelling packages at all therefore i can't
say much about 'boning' and the things required for that, but looking at
Rune's first proposal i think implementing a transform weighting method
would really be the first step (either in SDL or as a patch) Having this
function limited to meshes would be a major restriction (just imagine
blobs could be nicely 'boned' too)
