MarkerArray
MarkerArray is a ROS (Robot Operating System) message type used for visualizing multiple markers in a 3D environment. It is commonly employed for debugging, visualization, and interactive tools in robotics development. A MarkerArray message contains an array of Marker messages, where each Marker message describes a single graphical object.
Each Marker message can represent various geometric shapes such as points, lines, cubes, spheres, cylinders, cones,
The MarkerArray message is particularly useful for visualizing sensor data, robot paths, planned trajectories, or debugging
