Hi! There is a new ROS interface for OctoMap in the works, and I would like to get some ideas on what would be useful or nice to have in such an integration. This interface (or wrapper class) should expose the obvious functions to use, and should make it easy to use OctoMap in ROS without manually converting too much between ROS / PCL types and the native OctoMap types. You can check out the current stage in the package octomap_ros of the octomap_mapping stack in alufr-ros-pkg [1]. The most-important functionality (inserting scans or single beams, raycasting, 3D queries) is already there in "OctomapROS.h", along with a few conversions in "conversions.h". Let me know if you think there's anything important missing.
