From: An extended triangulation to the Marching Cubes 33 algorithm
Non-manifold issue caused by the Chernyaev lookup table. a The zero-level set of a 5 ×5 ×5 randomly generated piecewise-trilinear scalar field. b The mesh generated by our method, in our implementation, was included the solution proposed by Custodio et al. to fix the problem. c The mesh generated by an implementation of the Marching Cubes 33 algorithm has two non-manifold edges caused by the triangulation proposed by Chernyaev
