inflate + collide

hey, i tried modifying the inflate definition to compute collisions between bubbles...i'm using a interconnection-PLaw system, and...A; it's not working, B; i feel like there should be a better way...what's the standard kangaroo collision method?

 

i checked out the cradle definition...but it's between single points...

    Hi Gabriel,

    See this discussion for a little more info on collisions with Kangaroo

    I can see how collision between inflating meshes would be quite a nice thing to have, and maybe there is a simplified approach possible, where points inside are just pushed out towards the closest point on the mesh, similar to how the 1-way Brep collisions work now, and push the points of the face of the mesh being penetrated inwards in reaction. It might be slow though, and it's not clear how this might work to have meshes collide with themselves.

    In the meantime maybe there's another approach possible within current capabilities, it depends what you are trying to do ?
