Visualizing octomap in rviz

• plotting-a-markerarray-of-spheres-with-rviz
• they suggested to get the electric version or later version of rviz where there is MarkerArray type display.
• octomap_server publishes topic occupied_cells_vis_array. I was unable to visualize it. In rviz (diamond back version), there is no display type called MarkerArray. There is Markers type display, that I can add from the display list. Finally, I added Markers type display with topic name occupied_cells_vis (notice I omitted _array as suggested by others) and I can visualize the octomap in rviz.

• Try rostopic echo normals_marker_array to see if messages are actually being published.
• I did something similar: rostopic echo occupied_cells_vis_array to see the message in the topic occupied_cells_vis_array published by octomap_server
