When I was reading an jitter example patch, pool-3d-nurbs, I have found that the resulted vertexs of the nurbs surface generated is not even.
In jit.gl.nurbs.help, a random surface looks fine with even distribution.
I guess it is because it used a linear interpolation to generate the control points for the x- and y-axis.
I was trying to fix it, but seems I do not know throughlt the tricks of nurbs ..... any hint I can make the nurbs surface in pool-3d-nurbs have an even distribution ???
