Is there an equivalent to 'order' interpolation on gl.nurbs for gl.mesh

Hi list,

I do not quite understand the mechanics behind the function, but order used on jit.gl.nurbs does smooth the curve of the grid between (?) the points composing it. I am trying to reproduce a similar effect on a gl.mesh, but I do not know where to start.
Here is a small example patch of what I wish to acomplish. Changing the order value on the nurbs smoothes its curve. Is it possible on a mesh ?

Thanks in advance for any hint
