Feature Request: Support for Import/Sync of OctoMaps

[eric-schleicher]

WHY: Octomap is a broadly accepted library (defacto standard) for capturing and representing occupancy of spaces in robotics. being able to bring these occupancy grids into Unreal (and into Voxel Plugin specifically) enables a great number of new and potentially very compelling visualizations and user interaction possibilities. While there are some rudimentary visualization capabilities within/adjacent to ROS for octomap structures; we are interested creating a pipeline from a ROS host into Unreal via VoxelPlugin to make possible immersive VR and 3d experiences that unreal/VoxelPlugin make possible

Incremental possibilities:

1. The ability to import a (static/serialized) Octomap structure using Voxel Plugins approach/underlying representation(s).
2. The ability to subscribe to a live ROS hosts and incrementally manage a low(er) latency state representation of a running Octomap.
   • such synchronization would be achievable using one of the established connectors for ROS/Unreal like: https://github.com/code-iai/ROSIntegration
   • http://wiki.ros.org/octomap_server would facilitate establishing subscriptions to a live octomap:

Casually ran across this which might be relevant prior art. not sure if it's at all useful in the context rudamentary import functionality
