### developable surf？

The algorithm is simple.First step is to build a surface Normal field.And then use laplace equation to draw the polylines on which each normal are perpendicular to a same vector.  The cons are obvious.Cause I use the  Normal field to draw polylines. Each mesh face is not quite plannar.See More
