smoothing without the shrinking: every smoothing pass is followed by a slightly larger unshrinking one with a negative step, so the gain over the pair, (1 - lk)(1 - mk), is about one over the low frequencies and the area is given back. This is approximate; the areas move, only not systematically one way (Taubin, SIGGRAPH 1995)

Input

iter number of smoothing and unshrinking step pairs; default 5
lambda_ positive smoothing parameter; default 0.5
mu negative unshrinking parameter; default -0.53

Members

smooth the vertices after iter pairs of a smoothing step lambda_ and an unshrinking step mu, the fixed ones kept
