CURVE CREATION

B-spline curves

interpolation, fitting; energy minimization curve fairing; fair curve on surface; curve with ;; length; parser and convert equations into NURBS curve; curve extracted from mesh boundary, image silhouettes, and free-hand sketching.

Curve faring by energy minimization. When interpolating the six blue sample points, using our curve fairing technique, the new gray curve is better than the original red curve with much more smooth curvature combs of new curve (yellow) than the original one (red).
