In ShowFaceNormal.net the module GenDat computes some data. The module IsoSurface uses the data to compute a surface. This surface is drawn by the renderer and also given to ShowFaceNormal. ShowFaceNormal computes the centers of the polygons and their normals. The vector data is visualized by the module Vectorfield. The output of Vectorfield are lines which are the normals.
