Cannot visualize PointCloud2 topics through rviz or openni_viewer [closed]

edit

Hi,

I'm trying to visualize /points2 topic through rviz or openni_viewer. Even though I'm getting average rate: 2.989 min: 0.193s max: 0.759s std dev: 0.08753s window: 34, it will not show up in the visualization.

I used rosrun pcl_ros convert_pointcloud_to_image input:=/points2 output:=/test then rosrun image_view image_view image:=/test to test that pointcloud topic works and I can see the image...

What am I doing wrong so that I cannot visualize the pointcloud through rviz or openni_viewer?

Rviz: no errors, just white dot in the middle. Openni_viewer: just blank

Thank you
