Arbitrary Contact Mesh

Post by Connor Stapp » Mon Mar 26, 2018 1:26 pm

I'm currently working on a project where two objects come into contact and need to have a contact mesh between them. I've tried using the standard contactsphere that I've seen but it doesn't seem to work. Does OpenSim allow for arbitrary contact meshes and if it does, are there examples on how to write one?

The "From the Ground Up: Building a Passive Dynamic Walker Model" example in the Confluence documentation demonstrates how to use ContactSpheres (see https://simtk-confluence.stanford.edu/d ... lker+Model).

Here is a SimTK project that uses ContactMeshes: "Evertor and invertor muscle co-activation prevents ankle inversion injury" (https://simtk.org/projects/ankle-sprains).
