<br>
I wonder whether it would be possible to have rviz display the occupancy values<br>
of the nav_msgs/OccupancyGrid message as probabilities instead of the current<br>
ternary representation as occupied/free/unknown.<br>
I think this decision is due to the fact that the costmap_2d package uses the same<br>
ternary representation. However, according to the message definition, the data<br>
field is supposed to store probabilities in the range of [0,100]. Hence, I think it would<br>
be more consistent and less confusing to have rviz indicate those probabilities in some way.<br>
I included a small patch which does what I think rviz should do.<br>

hello,<br>
<br>
i am trying to visualize a likelihood field in rviz. but when i use<br>
nav_msgs/OccupancyGrid rviz only distinguishes between<br>
occupied/unoccupied/unknown and ignores all other grey values. How can I<br>
workaround this? Sending a different colored Marker/Cube message for<br>
every grid map cell would certainly do the trick but may be not very<br>
efficient.<br>
What would you recommend?<br>
