Since the “Sine Surface” has become vey popular, it’s best used in educational settings where quick and effective parametric surfaces are needed. However, I tried to further develop this idea to create not only the sine edge surface, but also a surface that can be mapped by any graph function. The definition found here [2011_12_22_sine]does calculate points according to a graph output, but does not create edge surface yet. Here is an updated version of this project Update: Here is an updated version of this Grasshopper definition: [GHX: 0.9.0072]
