Is the input file only in pcd format when annotating 3D point clouds?

Thank you so much for your tool, it's excellent. I have a problem, my point cloud file is a txt file containing xyz and rgb, or a ply file. How to use txt file as input?

Hello, yes PCD is the only format supported. However you should be able to convert your text file to match the PCD format, here is an example.

Thank you.I use open3d to convert the ply file into pcd format. The pcd contains rgb information, but it only shows gray, how to show color?
