Detailed Description

Contains two arrays of normals (polygon normals and vertex normals).

"polygonNormals" are normal vectors on every polygon, used for culling polygons. "vertexNormals" are normal vectors on every vertex, used for lighting. Vertex normals are the average of polygon normals of the polygons adjacent to a vertex.

NormalsNode provides storage for normal vectors and flags. Graph (VisitorDraw) is responsible for computing/transforming them. Events that affect normal vectors, such as matrix rotation or polygon mesh deformation, require notifying NormalsNodes by calling SetRecomputeNormals()/SetRetransformNormals() to schedules updating normal vectors appropriately.
