Surface Deformation

[ogeorges]

Hi guys!!!

I don`t know if i post this message in the right forum, but never mind, i try

I`m in the process of developping a Maya plug-ins deformer to deform an object with another one ( remember the shrink wrap tool in softimage|3D )

I know Dirk Bialluch ( CPS author ) has developped a long time ago a commercial plug-in named if i remember well, Surface deformation, but unfortunatly i cant fine anything about this tool on www.lightstorm3d.com, the dirk bialluchs web site.

Any one have information about that, or have idea where i can find information to develop this kind of tool?

the tool is very good hidden.

I think you mean the Collision Deformer tool from Dirk

You found a picture under Portfolio -> Back to Gaya (the very last topic)

[ogeorges]

No its not the collision deformer, its another plug-ins that was on sale on the old dirk bialuch`s web site...
I think the name was surface deformer...

Maya has this built in its called Wrap, deforms any object with any other object, Yes it can even slide under skin. However if you wish the object a atop to collapse in other objects beneath theres several corresponding tools in muscle sims. Altough to be honest wrap can be set up to do this in many instances.

Hi Jooja

i know the Mayas wrap deformer and all the tips and tricks around this tool to make a sliding effect with it, but what i want to develop is really different, i dont know if you have ever use Softimage|3D, so i put a link to show you an example of use:

http://www.3drender.com/jbirn/hippo/hairyhipponose.html

The hairy nose has been modeled flat and then deform by a nurbs surface.

The plug developped by Mr Dirk Bialluch made the same thing, i remember an example movie on its old site showing letters deformed by a nurbs sphere.

I`ll try to contact dirk bialluch.

But if you have any idea where i can start my dev, you`r welcome Jooja

Ahh... (never say ALL, Everything and Never) but seems like you don't since you can do this effect with wrap too. all you need is to make a flat nurbs plane that matches topography of the one you want to wrap into then blend that patch into the shape of the target patch (you can even do this without blend by piping out shape to the wrap node). flattening for a nurbs patch is very very simple). Now its really a bad idea to remake the wrap sicne its very very optimized inside maya in way you cant even do with the api.

how about take a look at this :

[joojaa]

Yes, harmonic coordinates are VERY useful.

i`m afraid my mathematical knowledges are way to small to understand this kind of paper
But yes i think harmonic coordinates have a big potential to improve the deformation inside our 3D software.

Well i actually use something similliar for 2d textures! This way i can omit uvmapping altogether in some cases, and for procedurals its possible for waves to around around objects.

Anyway you can do all you need here with the wrap deformer. But please note the harmonic coordinate paper code couldn't do the example!

For the surface deformation, i have made a nice little rig that i can share, it`s pretty usable and there is only native maya nodes.

another paper maybe more ease to understand.
I am working to write a MAYA plug in for it.

Waou!!! Nice, im really impressed [img]style_emoticons/<#EMO_DIR#>/smile.gif[/img]
will you release this plug on highend? If so, im really eager to test it!!!!
