I don’t understand very well what Rhino means for Curvature.

Curvature is a real function of one real variable, but Rhino draws another curve in the Curvature Graph.

The second problem is: for a space curve, where is the torsion ?

Thanks

Hi Valerio - the height of the graph - the distance from the curve - is proportional to the amount of curvature in the curve, inversly proportional to the radius of curvature… modified by the ‘Scale’ factor. At scale = 100, the graph is *1/radius of curvature* high.

And the torsion ? Is that never important in 3d modeling ?
