Hello @wsung1, the functionality you are asking about is possible in Ouster Studio by applying a Range Filter, the steps to do that are described in the Ouster Studio User Guide on pages 26-29, but as far as I'm aware the Ouster ROS package does not provide such functionality at the moment in their visualizer or in RViz, unless you find a plugin for it, or implement an extra library that would give you that functionality, maybe you could check out pcl_ros
