[vtkusers] Why the vtkOBJReader->GetPoints->GetNumberOfPoints != the number in .obj file?

[Tsai_tow]

Hi,vtkusers！
	I use vtkOBJReader to load a .obj file.But I find that the number of points in the .obj file is not equal to
the one gotten by vtkOBJReader->GetPoints->GetNumberOfPoints.Why?
		Thank in advance!
