[vtkusers] about use vtkPolyDataNormals

[renlishen]

David, thanks~
I find the key point to my question...
If I don't use the vtkPolyDataNormals' SplittingOff()
I get more points and normals like this

but when I use SplittingOff()
I get the correct number of points and normals

but I don't know why vtkPolyDataNormals need to "splitting" the edge.....
anyway~thanks again for your replying...^^


p.s. my data has 5 points and 6 cell(face)
After using SplittingOff() ----> 5 points and 5 normals(pic2)
If no use SplittingOff()    ----> 16 points and 16 normals(pic1)
