Hi all, thank you for reading this post.

i don't get any images in RViz, not even sensor_msgs/images, just a black screen. I think it's a bug. cause i can see them using image_view pack. Now I want to visualize sensor_msgs/LaserScan without using RVIz, Is there any other way to do this?

Any answers would be appreciated.

In reference to the black screen, try updating your graphics drivers. This solved it for me (I too had the persistent black screen of death on every open of Rviz).

If you add a screenshot of rviz, we can probably help you debug why it isn't working. rviz also has a troubleshooting page that may be useful.

rviz really is the correct tool for visualizing data, because it understands the transform tree and can display different data sources in 3D, relative to one another.

If you just want to visualize your laser data to confirm that your laser is working, I wrote a simple laser viewer many years ago. I stopped using it once I discovered rviz.
