My Question

I have point cloud captured by a camera, whose SDK provides the possibility of exporting the point cloud as a .ply, or .pcd. When I save it as .ply, and load it into an open3d point cloud, I am able to visualize it. However, when I save and load it as a .pcd, I end up with an empty visualizer., although the point cloud information is all loaded. I also compared the values loaded into each point cloud and they are equal. Is there anything else that should be done? I am using the Cpp API, and I searched for similar issues, but couldn't find any. any pointers are appreciated.

Thank you !
