Hi Pilou,

re: same number of points.

Actually for export meshing, the number of control points in the surface doesn't really have any direct influence itself on the output mesh, instead only the actual geometric shape of the surface influences it.

For example it is possible to have a plane that has hundreds of points in it:



However, when exported as a mesh, this will create one quad:



That creates one quad because one quad is all that is needed to match the geometric shape of that surface, even though the surface was defined by hundreds of control points.

However, having said that, several surface construction mechanisms are adaptive and will construct surfaces with more points in areas that are more curvy or bumpy, so that increased points on the one side is kind of an indicator that there is probably a higher amount of curvature in that portion of the object than in the other side.

Higher curvature is part of the geometric shape of an object and does have an effect on the angular meshing parameter.

I still haven't finished looking at the one result that seems unexpected, I just wanted to give some information here about the "same number of points" part.
