I just tried the ros_pcl first tutorial. everything goes well till catkin_make. but after launching the camera node and running command :rosrun my_pcl_tutorial example input:=/camera/depth/points, it shows nothing. after running rosrun rviz rviz also it shows nothing. i am using kinect xbox, with ros indigo, ubuntu 14.04.

im getting this message after i run freenect launch:

[ WARN] [1465146330.631433542]: Could not find any compatible depth output mode for 1. Falling back to default depth output mode 1.
[ INFO] [1465146330.648912116]: rgb_frame_id = 'camera_rgb_optical_frame'

Although this are just warning, and the kinect is working propersly, why do i get nothing when i run the example.cpp. it shows nether error nor any message. even after running rvij nothing. i just got adopter for my kinect and tried to run this. before i've build the package and their was no error at that time. but now. o man.

ok, now i got the output, but it is looking little different though. the mistake i was doing was while adding pointcloud2 in the rviz. Problem solved, now it will not be difficult for me to run other pcl tutorials also, yes, hurray. but the point cloud color is white, it should be colurful.

have you tried changing the pointcloud channel to RGB? Have a look at the documentation for the pointcloud rviz display
