I use parallel Desktop 6.0 on macbook to install ubuntu 11.04.

I run the following instructions:

  rosrun hokuyo_node hokuyo_node
  rosrun rviz rviz -d `rospack find hokuyo_node`/hokuyo_test.vcg

Orbit views:

Obviously it is not correct. Because the laser data point is not only a line.

When I try the same laser range finder at the other computer,it works normal.

Like this screen shot:

How to fixed it?

Can you clarify what exactly is incorrect about what you see? I'm having trouble from the screenshot.

I have updated the original post to add the normal picture of laser range finder.

This looks to me like an instance of the bug described here, where point clouds are not being rotated correctly.

The other reporter was also running Ubuntu on a Mac.

Try changing the view dropdown to "orbit" and rotating the camera around the laser's origin. Looks to me like in your first image the camera is in the same plane as the laser, but in the second the camera is giving you a top down view of the data. "Orbit" mode will let you change the camera angles and see if that makes a difference.

Ah, okay, I see what he was referring to as "wrong" now. I think that it's just an orbit issue as well. I have had no issues with Parallels/Natty/Snow Leopard that I can think of.

I updated the original post, and I have changed to orbit views,but the result is the same.
