WebJan 27, 2015 · For smooth shading, two adjacent triangles must share common vertex normals. The reason is interpolation. The normal from one vertex is smoothly interpolated to the normal on the second vertex. You need to ensure that the normal of triangle at a particular vertex matches the normal of all adjacent triangles at that same vertex.
