How do you visualize "tensor field" ? #2

Hello,

Could you please tell me how to visualize "tensor filed" ? How to show the current status of motion planning ? I have Rviz on, but I cannot locate any relative topic to "motion field"

Thanks for the nice SW

If the whole system goes up, you can vis the tensor field on Rviz by subscribing to the topic of "/semantic_targets", which is published in listen.py. Maybe you should first check to see if the node of listen.py is runing.

Thanks for the quick reply. I can see the node "listen" is up. Besides, I do see the topic "/semantic_targets" is published by the node "listen". Unfortunately, I don't see this topic in Rviz though. I found "MeshDisplayCustom" under rviz_textured_quads instead. But, clicking this topic crashes Rviz immediately. Do you have any idea ?

Thanks for your help.

Hi, the "MeshDisplayCustom" is provided by plugin of rviz_textured_quads. You said Rviz crashed when you clicked the topic, I think that may be the problem. You can catkin_make the packages of rviz_textured_quads separately to if the "MeshDisplayCustom" works on Rviz. There is also a demo launch file in package of rivz_textured_quads.
