Tetrahedral cutting and collision

[lNatxii]

Hi Justin,

I have a very similar problem, because colliding and visual meshes are not working as expected. I can see the cut mesh but objects are still colliding and the VisualGeometry is still the original one. I can see the cut mesh because I’m using the extractSurfaceMesh function.

Look at this, I posted all here:

DeformableModel.cs optimization (iMSK-Unity)

Then, the main problem is the next one: As I can’t compare vertices indices because iMSTK reuses the deleted vertices and reorder the array to make the “new” modified mesh, I need to compare positions. The problem is that visual geometry filter is not updating ANY information about the new mesh even if I set a new inputMesh, so I can’t compare correctly. Now I’m comparing vertices with a tolerance, that doesn’t allows me to use a better way like dictionary, that would allow me to use positions…

Basically, I can’t update visual and colliding geometries.
