- [Instructor] Welcome, I have my Exercise File open already. In the last video, I was looking at the NGon plug-in for Grasshopper. Specifically, the conformal mapping feature or the mesh mapping feature, where it does a boundary first flattening, kind of a type of mesh flattening that preserves the boundary of the mesh, but does distort the distances within the mesh vertices. And then use that boundary first flattening to map curves from 2D into 3D, onto a three dimensional map. Similar to the conformal mapping that you would do for animations or rendering. In this video we're going to extend that a little further beyond the straight lines to see how the conformal mapping process gives you some controls, that would be pretty hard to replicate using other techniques. So first off, we're going to focus on the surface. So, when we do the conformal mapping, we're unrolling that mesh fine. And then we're creating a…
