field one: surface

 

This definition creates a surface based on the normal lines extracted from a sine surface.

First a bounding box was created that contained a variable grid. Next a series of variable sine curves were created along the x-axis. Points were extracted from these sine curves, then connected. The five defined sine curves were then lofted into a surface. This alone makes an interesting surface.

The next portion starts with finding the normal curves created at variable intervals. By isolating these end points, then connecting them into another set of curves, a new lofted surface can be created. This final surface can fold onto itself.
