The TETRA_SURFACE function extracts a polygonal mesh as the exterior surface of a tetrahedral mesh. The output of this function is a polygonal mesh connectivity array that can be used with the input Verts array to display the outer surface of the tetrahedral mesh.
Result = TETRA_SURFACE (Verts, Connin)
Returns a polygonal mesh connectivity array. When used with the input vertex array, this function yields the exposed tetrahedral mesh surface.
Array of vertices [3, n].
Tetrahedral connectivity array.
