hector_quadrotor color settings for laserscan

edit

Hi,

I am trying to reproduce the same color behaviour from the "hector_quadrotor outdoor scenario demo" youtube clip. In this clip in the top down view from rviz the hector team gets a nice color visualization of the laserscan.

What settings do you choose in rviz under the LaserScan category to achieve the same?

I tried various and I'm currently using:

• Topic: /scan
• Queue Size: 10
• List item
• Selectable: yes
• Style: Points
• Alpha:10
• Decay Time: 10
• Position Transformer: XYZ
• Color Transformer: AxisColor Axis: Z
• Autocompute Value Bounds: yes
• Use Fixed Frame: yes

With this setting I get a very colorful image but to me the colors don't make sense at all. There is no consisting color change as it can be observed in the hector youtube clip. For example I get green lines after blue ones and then blue again.

I use Ubuntu 12.04 and ROS fuerte and run the outdoor_flight_gazebo.launch file from the hector_quadrotor_demo package.

Thanks a lot.
