Ribbed Benches with Rhino + Grasshopper

The development of these benches derived from three simple components: a bench profile curve, a rail curve to follow, and a cosine graph to extrude the back rest of the bench. The second bench was added onto that concept by reversing the back rest along the curve path as shown below. A tutorial and diagrams will hopefully soon follow. This was also an attempt of using Maxwell Render for the wood material and representation.
