Mesh between points?

It is less accurate with things that have extreme curvature. As David said, it is about the breaking down of triangles. The more dense the mesh representation of curvature, the more accurate it will be - but the slower it will be. In this case where faces are kind of almost planar, it doesn’t really make a difference.

Thanks David, that’s very clear. And thanks Michael for making the very clear even clearer.
