Hi： I want to konw how to get a simulation picture form your code, just like this in your paper: https://user-images.githubusercontent.com/63492361/145538720-4f84d456-9387-40a4-b495-21dd7670ee12.png and this: https://user-images.githubusercontent.com/63492361/145539035-d12db0f3-fd7c-44c4-95a4-3e0772c9eec7.png While running the simulation, it only show part of mapping ,like this: https://user-images.githubusercontent.com/63492361/145539723-88920ceb-f8c3-4235-9615-d7e6cc7e047c.png

   Look forward to your favourable reply

Just increasing the "Decay Time" in the pointcloud2 topic in the Displays panel. It's the parameter telling rviz how much time to keep a pointcloud message.

Thank you for your reply, but it seems doesn't work: https://user-images.githubusercontent.com/63492361/145570689-eb7c4764-f761-481d-939f-5f233c3e58f4.png It's there something else I need to set?

It seems that you are editing the wrong topic. Try to uncheck each topic and see which one is currently displaying. I'm sorry to reply you now , because something else I stopped this work a few month ago! Today, I follow you advice try every topic in PointCloud2（eg:/grid_map/occupancy, /grid_map/occupancy_inflate,/grid_map/unknown,/map_generator/global_cloud,/pcl_render_node/cloud）, but still didn't work. Hope for your reply, thank you so much
