Hello, I am preparing point cloud ground truth data for training for CGAL classification, which requires me to feed a .ply point cloud with 'property int label' I am wondering if given a raw point cloud imported in meshlab, could I create a new property map for the point cloud and give label on selected points? And finally being able to export the point cloud back to .ply with 'property int label' ? If no, wondering if any tools /software that allow me to do that? Thanks for the advise! William
