Since a PLY file of binary format can save space, I test the PLY tool in MRPT. I first load a PLY file of ascii format (this file can be shown in 3DSceneViewer) into CPointCloud, then I save the points into PLY file of binary format using the saveToPlyFile method of CPointCloud. But this PLY file of binary format can not be shown in 3DSceneViewer (only very few points are shown).
I try to use loadFromPlyFile method to read the binary PLY file, I receive errors:
RPly::binary_get_element: Error reading binary file!
