Simple Self CollideAuthor: Julien Silvestre
Julien's take on Paul Smith's Skin Collide concept. This deformer attempts to avoid self intersections by using ICE raycasting to push »inside« points to the outside.

Here a simple self collide deformer:


For sure it's not perfect, but i think this compound can be usefull.

Critics and comments are welcome.
How did you make two objects collide ? I'm trying to do that.

j3st3r: i have look inside you scene, to remove this kind of problem you have to setup the parameter "distance" to 1 almost the time. But sometime for extra pose you can tweak the penetration by animated this parameter.
For exemple on you scene (see attach) to remove the issue i've key the parameter at 1 from key 1 to 65 and then to 2, and it's work fine. Like i say in the first post the compound is not perfect and need to be optimised.

Falam: on the video i use only one mesh on each example, if you need to do a collide between different object, you can do it easily in ice without this compound. This compound is use only for a self collide.

hello,
i've attach to this message a quick exemple on how create deforming collision between two different mesh.
Hope it will help.

Bye

That was an interesting study :) I don't want to ask more questions related to my ICE issue, when this is your thread ? :)
