Class npoint: usage

Constructor

– npoint p(0.0, 0.0, 0.0, 1.0); // Euclidean point (0, 0, 0)

Get coordinates

– double x = p[0]; // Get coordinate x – … – double w = p[1]; // Get coordinate w (always 1 for the moment)

Set coordinates

– p[0] = x; // Set coordinate x – … – p[3] = w; // Set coordinate w

Class nlagrange: usage

Constructor

– nlagrange curve(7); // Create a lagrange curve with 7 CPs.

Get/Set parametric values

– double u = curve.u(i); – curve.u(i) = …;

Get/Set control points

– npoint cp = curve.CP(i); – npoint new_cp(…, …, …, 1); curve.set_CP(i, new_cp);
