I'm trying to find a standard (or, at least, not completely obscure) binary data format with which to represent an X/Y/Z+R/G/B point cloud, with the added requirement that I need to have some additional metadata attached to each point. Specifically, I need to attach zero or more "source" attributes, each of which is an integer, to each point.

Is there an existing binary data format which is well-suited to this? Or, perhaps, would it be wiser for me to go with two separate data files, where the metadata just refers to the points in the cloud by their index into the full list of points?

据我所知，PLY 格式允许附加到每个元素的任意长度的属性列表，并且可以具有 ASCII 或“二进制”格式： http: //www.mathworks.com/matlabcentral/fx_files/5459/1/content/ ply.htm

据我所知，PCD 只允许固定数量的字段： http: //pointclouds.org/documentation/tutorials/pcd_file_format.php
