Just a simple demonstration of the Mezz Deformer I'm working on.

Comments appreciated!

Cool, but it gets a bit blocky. 
What's the main advantage of your method?

Not quite sure what I would use this for, but it looks cool, nonetheless....
Hey! Why don't you twist that cadillac model that's so popular? Or better:
make it "walk" along in the way a snake would move... :)

fine. looking at your example I have a question
is there any difference beetween this result and results of my deform patch
presented in p.b.i during last month ?
as long as you work on mesh this is faceted
but my patch work fine with *any* object
I'll make animated example for you
perhaps there should be speed comparison
mesh->mezz->rendering will win
but perhaps deform->teselation->rendering could be more accurate

Last I heard, your deform patch could do reversible deformations only.
With my method any deformation can be done.

Doesn't this slow down the rendering?
My method does not slow down the rendering at all. The parsing is a bit slow
though.

My method produces results as accurate as the input mesh is.

Good idea!

I'm not used to working with imported meshes though.
Does anybody have that cadillac model in PCM format?
How big is it when zipped?

Thanks!

It's blocky because the mesh is of a very low quality.
The torus and sphere PCM files included with Chris Colefax's Compressed Mesh
Macros are the only PCM files I've got so far!

Advantage over what?

Advantage over other methods (but I can't think of any right now).

Anyway, I noticed you're doing something with meshes (mezz) but I'm not sure
what you're trying to accomplish. I'm interested though, I like meshes and it's
nice to have ways to deform them.

Oh, and I forgot to ask you if I could use your Torus Torture in my Torus
Interrogation Chamber?

Chris Colefax's Compressed Mesh Macros can also deform meshes. The advantage
of the Mezz Deformer is that the normals are handled correctly, and that the
texture sticks to the objects when deformed. It uses more memory and parsing
time though.

To be able to deform meshes with correct normals and texture mapping... :)

Sure, as long as you give me proper credit! ;)

how normals are calculated ?
did you considered my method sended for you to p.a-u ?
