I was wondering if you could help me with a high order viz problem. I am implementing a high-order DG code that is strictly cartesian. I want to be able to call gmsh as a library and have it make 3d triangulations of isosurfaces. I also want to do this one cell at a time. Therefore I won’t enforce any continuity between cells. Ideally, I would call gmsh with a domain that is a cartesian hexahedral cell (eg cube) and a callback function R3->R. It would then return a list of nodes and triangles. I also don’t care if the mesh is perfect since this is for viz. It can have intersecting triangles or bad triangles.
I see this capability in the high-order viz paper on the gmsh website and I was wondering where and how to use it in the gmsh code. Also, do you have an code example of how to do this?
