Understanding ROS visualization tool (RViz) and its plugins

The RViz tool is an official 3D visualization tool of ROS. Almost all kinds of data from sensors can be viewed through this tool. RViz will be installed along with the ROS desktop full installation. Let's launch RViz and see the basic components present in RViz:

Start roscore
```
$roscore
```
Start RViz
```
$ rosrun rviz rviz
```

The important sections of the RViz GUI are marked and the uses of each section are given as follows:

Figure 6: RViz and its toolbars

Displays panel

The panel on the left side of the RViz is called Displays panel. The Displays panel contains a list of display plugins of RViz and its properties. The main use of display plugins is to visualize different types of ROS messages, mainly sensor data in the RViz 3D viewport. There are lots of display plugins already present in RViz for viewing images from camera, for viewing 3D point cloud, LaserScan, robot model, Tf, and so on. Plugins can be added by pressing the Add button on the...
