Hello,all. I am a Japanese student.

I want to display the 3D Map in rviz.

But I don't know how to do it.

The 3D Map data file is "cloud.ply".

Is it possible to open this data with rviz?

Please give me some advice. I’m sorry for the poor English.

Thank you in advance!

You should create a node that opens the file and publish the point cloud to a PointCloud2 topic. Then, visualize this topic in RViz.

You could read the file with pcl::io::loadPLYFile to obtain a pcl::PointCloud<pcl::PointXYZRGB>, then transform it and publish the result.
