PLY header conflict (vertex_indices)

[VictorLamoine]

rdcelis reported an issue with the PLY parser, the header is filled with vertex_indices instead of vertex_index

See the PCL discussion for more information.

See #579.

[RDCH106]

The problem not solved.
I use PCL 1.7.2 with the changes implemented in #579, but the headers with the property:

-property list uchar int vertex_indices

Crash when you load a ply file with loadPLYFile.

There is also #675

PCL trunk, it looks like this issue if fixed.

  pcl::visualization::PCLVisualizer viewer;
  viewer.addPointCloud(pc_2);
  viewer.spin();
  return (0);
