Hi,

in this animation the shape morphs between a square
and a sphere-function. Nothing special, but it shows
how it could work.

Looks like some kind of fade-over to me   :-)
Maybe using some way of moving control points would produce more morph-like
animations. Imagine morphing 2dimensional pictures instead of fading them
from one into another. But this time it should be 3dimensional instead of
2dimensional :-)

hmm, yes you're right, it's a kind of fade-over of the two fourier-functions.
That was my goal, i didn't want to (and couldn't ;) )make a NURBS(or whatever)
-like morphing. Perhaps it doesn't look so good with these two shapes, but i
think with more 'real' and more similar objects it will look fine.

I expected some very funky and Terminator-II-like morphs!  :-)

Why is the DivX 4 times longer, and slower, than the Mpeg? Did you do this
to save space? I like the animation but frankly I can't think of many uses
for this as long as the shapes have as many artefacts as they do now.

Both animations consist of 120 frames but the divx plays at 10fps
and the mpeg at 29.97fps because Videomach says that mpeg is
limited to that framerate.

Thanks

yeah, i know what you mean. The artifacts can be compensated with more
harmonics. In fact you can have as much details as you want, but it's
computationally expensive. Moreover these were extreme shapes and i
hope it will look better with more similar objects. I will post a new
animation when the analyzer-macro is done

? AFAIK that's not true (it does have limited framerates, but they go
lower than that). Check out my avi2mpg post in
povray.binaries.utilities; it's a command-line program, but usable
enough.
