Visualise point cloud in real-time

edit

Hi

I'm new to ROS and testing out a cheap RGBD camera. The camera has the topic /camera/depth_registered/points for xyz rgb point cloud. I'm trying to visualise it using rviz by adding a new PointCloud2 display and setting Topic to /camera/depth_registered/points. However, the display is blank even when the camera node appears to be sending messages:

  6013211 VERBOSE    [FPS] IR: 0.00 Depth: 31.01 
  7029933 VERBOSE    [FPS] IR: 0.00 Depth: 30.11 
  8010593 VERBOSE    [FPS] IR: 0.00 Depth: 29.91 
  9003788 VERBOSE    [FPS] IR: 0.00 Depth: 29.76 
 10020535 VERBOSE    [FPS] IR: 0.00 Depth: 29.76 
 11004264 VERBOSE    [FPS] IR: 0.00 Depth: 29.73 
 12027005 VERBOSE    [FPS] IR: 0.00 Depth: 29.76

Anyone know why this is the case?
