Detailed Description

Displays a point cloud of type sensor_msgs::PointCloud2.

By default it will assume channel 0 of the cloud is an intensity value, and will color them by intensity. If you set the channel's name to "rgb", it will interpret the channel as an integer rgb value, with r, g and b all being 8 bits.
