Hi, When I look into the source code of vtkCubeSource.cpp, I noticed that, although a (rectangular) 3D box can be described by 8 3D points and 6 2D faces (hence also 6 3D normal vectors), in the actual code of vtkCubeBoxSource:RequestData() there are 24 3D points generated, with for every point a normal (???), and indeed 6 faces (polys). Why is there this redundancy?
I bumped on this when I applied the "HiddenLineRemoval" representation to my own handcrafted box (with 8 points, 6 faces and 6 normals). It yielded an incorrect view whereas the box with the redundant numbers of data gave the correct one. But I don't get the logic.
