Is it possible to mark certain triangles that you wish to remain the same with mmgs? Then remesh the surface and only have the unmarked triangles remeshed?
This feature is not yet implemented but Mmgs can preserve marked edges.
Thus, you can give to Mmgs the boundary edges of the triangles that you want to preserve and mark them as “required” using the MMGS_Set_requiredEdge(MMG5_pMesh mesh, int k) function (k is the index of the edge that must not be remeshed).
Okay, thanks for the information!
