vtkPLYReader does not work with faces described with vertex_index property
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
In the PLY file format definition there is an ambiguity on how to define the topology of the model. The list of faces should be described with the vertex_index property, but is possible to use also the vertex_indices property (http://www.dcs.ed.ac.uk/teaching/cs4/www/graphics/Web/ply.html). vtkPLYReader is able to recognize only the vertex_indices property, so, when the face list is reported with the vertex_index property, the ply file is not correctly parsed. It should be able to look for both the tokens.
