Animating Poser characters can be already be done within Poser and the
results can be exported to Povray. I did a test with a few hundred running
horses some time ago.
You're right in saying that character animation is a weakness of POV-Ray,
but I fail to see how a POV-Ray-only solution could be useful from a
practical point of view (I mean for creating full animations, not just tests
to prove a point).

Apart from personal preferences this has clear practical reasons.

Oh, come on.  This is not a 'ask for a feature and someone will program it
within a day'-club.  A few critical opinions and suggestions for
alternatives and someone starts thinking you are ignorant and not
constructive... ;-)

Huh?

Just because I don't let you see it does not mean that I am not still
using POV-Ray for both stills and animations. In fact just three weeks
ago I was working on using ISOs to model the effects of rain drops
hitting a pool of water complete with photon generated caustics. Didn't
quite get the effects I wanted so I moved on to something else. I have
a long history of half finished projects that seldom get to the point
where I feel they are worthy of sharing with others.

I didn't mean to offend you in any way - I've seen a few of your images and
they're very nice.

Yet still you're not the person I'd expect to make animations of the kind
I'm thinking of. Which also seems to be what you say yourself. That doesn't
mean though that others won't have any use of the feature in question.

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.
