points < 65000
Interactive singular "cone" Loop subdivision spline. Use your fingers or mouse to control the model (hold shift key or use mouse wheel to zoom it). Canvas is matched to your browser window.

The first CMesh point (0.5, 0, 0) is just fixed (excluded from averaging process) by hand and we know the normal (1, 0, 0). It seems that accurate normals are not very important at singularities.
