How can I visualize an existing point cloud in rviz? I went through tutorials but it appears they use sensor data. I have a point cloud in bpf format and have tools to convert it to las format as well.

I am using ROS Melodic on Ubuntu 18.04.

You can convert it from a las to pcd using the las2pcdtool provided here: https://github.com/murtiad/las2pcd and then use the pcd_to_pointcloud node in pcl_rosto publish the pointcloud as (similar to https://answers.ros.org/question/6212...)

rosrun pcl_ros pcd_to_pointcloud <file.pcd> [ <interval> ]
