This package is part of Robot OS (ROS), and provides a set of messages used by higher level packages, such as rviz, that deal in visualization-specific data.

The main messages in visualization_msgs is visualization_msgs/Marker. The marker message is used to send visualization "markers" such as boxes, spheres, arrows, lines, etc. to a visualization environment such as https:///www.ros.org/wiki/rviz See the rviz tutorial https://www.ros.org/wiki/rviz/Tutorials for more information.

This package contains the message definitions.
