I may be trying to reanimate part of the earliest stages of the
development of the heart. This is for educational purposes, just to be
able to tell what is going on. We have microscopic reconstructions of a
number of stages. The object is mainly 2 dimensional but highly curved.
What I need to do is fit some object with far fewer parameters than the
original voxel data. Do that for one stage and use only deformation to
get to the next level that is in general more complicated. There has to
be a smooth interpolation between stages and the should be UV mapped
because we want to show additional data in color.
I think I can mostly get away with a set of bezier surfaces, but I did
not like the control I had in blender when I tried something similar a
few years ago. At that time I decided to fall back on Matlab to write
the necessary SDL files. It seems to me that most of the support for
animation in various programs is more aimed at animating objects than on
growing and changing.
What would the knowledgeable people here recommend?
- use blender, perhaps a different primitive (I do use blender
regularly, but only the basics)
- wings or another program?
- any other suggestions?

This sounds pretty straightforward to do with any commercial 3D application,
either using parametric objects (spline-based etc.), vertex-based animation
or deformers depending on what you want to do (FWIW just tried Blender for
the umpth time and I'd rather not comment on it).

perhaps I should add some images to give an idea.
What I already made was
http://members.chello.nl/a.c.linnenbank/visitekaart/hearttube.mov
now we want something that starts out about as simple as that does,
perhaps slightly more detail and less symmetrical. Then it should
transform to a more abstract version of the top object in the attached
figure and then into the bottom one (were the tube is formed, curved and
in the middle disconnected from the rest.) BTW all this happens in a few
hours, impressive isn't it.

which one would you recommend (not that I have any spare money to burn).

I've been using C4D for a while now. It's quite easy to use so it's popular
with little animation studios. You can test drive the latest version (IIRC
it's fully functional for 40 days) from Maxon's site. The base module is
about 700 ? before taxes. Here's a little test I did in a few minutes. It's
vertex-based animation using one single low-poly mesh (with subdivision).
Note that your problem is slightly more complicated since the topology of
the object changes over time.
