PolySplines convert a polyhedral-net into untrimmed Bezier patches (NURBS)

Top: input mesh, Bottom: B-spline patches generated by PolySplines (Gray: regular , Green: extraordinary point, Cyan: T0, Yellow: T1-juntion)

 

Features

1. Smooth polynomial surfaces without splitting into too many pieces

   

2. Easy, exact computation of moments, e.g. volume, center of mass, axes of inertia, …
