Simple Self Collide
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.

Simple self collide deformer
Hello,
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.

Re: Simple self collide deformer
Thanks for sharing (video has disappeared). I tried recreating Pauls skin collision compound when he posted it but miserably failed . Will try something that works directly on the envelope weights next.. if that's at all possible

Re: Simple self collide deformer
sorry the video will be ok in few minutes, i've reupload it because i've some trouble to play it in non HD (i think bad resolution).
I see the paul smith video few time ago, he created a nice compound, i think his coumpound is better than mine, but i've decided to create my own from scratch in a way to learn more ICE.
Like to see the result of you process when it will be finish

Re: Simple self collide deformer
Thank you for sharing
Re: Simple self collide deformer
Nice! Can't wait to test it, thank you, Silvestre!
Re: Simple self collide deformer
Thanks a lot!
As a suggestion: is it also possible to combine this with volume preservation (via your fstretch-compound link or some other way)?
(The image is from an attempt of mine to do self-collision, being simple-minded it involves several shrinkwraps, collisiontargets and a fair amount of smooth operators, not flexible to set up at all)

Re: Simple self collide deformer
thanks for the comments.
druitre : actually my fstretch like compound don't work like the self collide compound.The self compound work with raycast and the fstretch like compound don't use raycast at all but it's a good idea i will look and try to apply a bugle effect onto the self collide
I've made some modification on the self collide in a way to fix some penetration problem see attached picture

Re: Simple self collide deformer
Did you upload the new compound? I still have serious issues even with a simple cylinder making the compound almost useless ...

Re: Simple self collide deformer
Hello j3st3r, yes the new compound have been updated. What kind of problem do you have? Can you share you scene with this problem?
Re: Simple self collide deformer
Does it work if the object is a child of a parent to collide with another object ? This compound falls into what I'm trying to do now.
Re: Simple self collide deformer
the compound works only with one object on himself
Re: Simple self collide deformer
I made a scene reproducing the issues

How did you make two objects collide ? I'm trying to do that.jujut wrote:Hello,

Re: Simple self collide deformer
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.

Re: Simple self collide deformer
hello,
i've attach to this message a quick exemple on how create deforming collision between two different mesh.
Hope it will help.
Bye
