External Usage of Tetrahedralization software
Due to restrictive open source licensing you can't distribute tetgen or tetwild to provide this tool in imstk or imstk unity. However, the tool is a very important and regularly used step when creating simulations.
It should be pretty easy to provide a path input in imstk settings or in a meshing dialog from the user to do the meshing without leaving unity & without including it in our package.
Additionally this tool is often used iteratively. It would be amazing and probably quite easy to get this working in Unity. Allowing you to mesh and 10s later simulate. As the meshing tool is often used iteratively when developing (through inspection of the output visually and through stats like number of verts, tets, various tet quality metrics, tetwilds own energy def, crinkle clips+visual inspection often used in paraview).
