I took the  fish/plant models from

  The conversion process entailed
    -toucan model (I think vrml format)from
http://www.toucan.co.jp/product/3ds/3dsFrameSetE.html
(Gilles Tran posting "Free Fish and plant Models" Aug 2)
 converted to Lightwave3d obj format using www.righthemisphere.com
    -I wrote a translator in MATLAB that converts the *.obj file to a povray
macro that adds a sine wave to the y or z axis(fish or mammal) as a funcion
of x axis of the triangle vertexes.   The sine wave is controlable in
frequency, phase shift, and amplitude of sine.  The amplitude can be
constant or sloped, in this animation the amp at the tail was 4 times that
of the head.
Fortunately I didn't have to adjust the normals.

I think I'll post the include files of the fish and mammals macros I've
generated at my povray web site that I'm constructing
http://www.xenomechanics.com/povray.html

VideoMach is probably the only mpeg software that I have not tried yet.
I have been using TMPEnc but up until ABX and Andrew postings I didn't know
how to fully use it.  Thanks to them I've been able to play the whole
thing...

The only problem with this (and if you use you imagination and look really
hard at the anim you can see it) is that the dolphins will tend to get
'squishy' heads, (ie, the skull and nose get deformed).

Other than that the dolphins are looking good.

Thanks for this. I just tried it with bmp's, and it seems to be working fine (encoding
now).

Yes, the dolphin is being sheared, like a stack of cards.  I went with this
approximation because I wasn't sure if it would bog down the rendering (but
it didn't seem to phase it).  I may try to rotate the vertex also...
Thanks
Tony

There is a plug-in for it that will accept png files as well.  It is in the
p.b.u newsgroup with a date of last fall sometime.

Thanks Tom, I'll check.

Hey, I found out that VirtualDub can also use a list of BMP's as input...
Just go to menu "file > open video file" and click on a BMP in the
sequence.. You don't even need the logo filter for this.

(VirtualDub is not for mpeg1).

Hugo

I tried it and I've missed something...
I opened a file say name.txt and entered a list as
name0001.bmp
name0002.bmp
....
name0675.bmp

but after browsing in the main TMPend window under Video source, it will not
except it.  What did I do wrong?   I'm assuming it can take bmp files.

Thanks
Tony

Hi Tony,

I think you've followed ABX's instructions a little too literally. You just create the
images,
not an actual 'list' (or txt file). Simply loading the first image in the sequence
into
TMPGEnc should work fine.
