Non-uniform density of surface control points

Want to achieve smooth surface at different ‘resolutions’ to be efficient.
Dynamic resolution of surface points. More or less according to varying complexity.
Non-uniform distribution option.

Video explanation.

after reading a couple of your topics, I strongly suggest to go with the training manuals level 1 and 2 to learn and undestand how Rhino works instead of trying to use it like other programs. in this case you have tools like insert control point and remove it. insert knot and remove it. etc.
Nurbs surfaces are not like polygons.

Investigate InsertKnot, RemoveKnot, InsertControlPoint and RemoveControlPoint commands.

InsertKnot does not alter the shape of the surface but moves existing control points. RemoveKnot usually minimizes changes to surface shape but may move existing control points.
