[vtk-developers] Strange problem with vtkPLYReader

[Bill Lorensen]

The PLYReader is fine. The file is not a proper PLY file. The face
indices should be zero-based, but in this file they are one-based. So,
the face
3 1 2 5
is referencing an point 5 which exceeds the points array which has
tuples from 0 - 4 (5 points).
