Mesh relaxation with collisions

by Andrew Wood

May 1, 2018

Hi,

Sorry to ask, but is there a way to have a mesh relaxation that also forms over other objects that could be considered as collision objects.

So, the mesh relaxes, but tightens over some other object like a sphere for example?

Many thanks in advance for any help on this.

    Hi Andrew,

    No need to apologize, this sort of question is exactly why this forum exists.

    Does this example help at all?:

    https://github.com/Dan-Piker/Kangaroo-examples/blob/master/collisio...

    It uses collisions between a closed solid and the vertices of the mesh which is being draped/wrapped. You can fix some anchors around the boundary and reduce the rest length of the edges to less than their start length if you want more of a wrapping effect.

    Also, if you want a sort of vacuum wrap effect where the mesh actually pulls into the concavities of the solid, you can use pressure with a negative value (on a triangulated mesh).
