Put the reader output through a CleanPolyData. The OBJ reader does not merge duplicate points.

Subject: [vtk-developers] .obj files

I am trying to load a file using the vtkOBJReader which reads an
OBJ file and returns a vtkPolyDataStructure. The file I am trying to
load contains 9000 points. However when it is loaded and converted to
PolyData it contains more than 40.000 points which is incorrect. I
printed out these points and I have all the points that are in the file
repeated 3-4 times each in random intervals inside the polydata
Do you know why this happens. Is there a known bug with vtkOBJReader?
Thanks for your advice!!
