In this map DomainSurface is used to generate a polygonal grid of the faces of the original 3D grid domain. GenNormals generates the field of normals to these polygons. Collect combines the information of the polygonal grid and normals in a single Geometry object for the renderer. Note that the orientation of these normals at the edges between two faces are in a way to convey the impression of having round edges.
