If you find an algorithm for converting a bitmap to polygonal instructions,
please share it with us. I would be interested in seeing it.

Hi,
I don't have any answer to this, but I'll need to solve the very same
problem in the future. So I'm looking for an algorithm to retrieve a
coordinates set from a bitmap image. Something like converting a bitmap
image into a polygonal one.
Is anyone having some reference (Books, URLs) for this?
About the modelling and extrusion: I'm not sure, but I remember that in
the Java Tutorial ("Collateral" section of the Java3D web page) there is a
section explaining exactly this and the reference to the supplied classes
to do it.
