"Great: looks super useful Can u explain this a litlle bit more: "And then use laplace equation to draw the polylines on which each normal are perpendicular to a same vector" u mean like a geodesic? where every normal to the curve,…"

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

"I smooth the mesh using Processing(eclipse plantform).then it looks better."

Flight of the Grasshopper

"Well nice job, I ever wrote shooting game using Processing. Instead of box ,I hang many small images which rotate and face to the camera all the time."
