robostack / jupyterlab-zethus Goto Github PK

Hello,

in our organization, we would like to use jupyterlab-zethus, but we have a problem with the visualization of markers. If I run jupyterlab with jupyterlab-zethus I can connect to my roscore and jupyterlab receives the TF and visualization_marker_array messages, but the meshes of the robot are not visualized in Zethus. In RVIZ I can visualize it and see the robot with the meshes.

Is it in general possible to visualize Markers with meshes in jupyterlab-zethus (or also in Zethus in general)?

First of all, thanks for this package. It seems to have a lot of potential for fast prototyping and visualizing.

When i open Zethus tab, i add my RobotModel visualization, frames (widget?) report stable 60 fps.
When i add Image type, it drops to 9-10 Fps. Moreover if i hide the visualization, it barely improves.

Only if i delete it, fps are back to 60. Same goes if i add a PointCloud type, but fps drops to 1. Again only if i delete it, not hide it, fps come back to normal (60 fps).

Note, jupyterlab-ros master was turned off by me and it's seem off in jupyter widget on the bottom part. I started it standalone on my terminal and launch rosbridge_websockets. Then i edided zethus configuration and set the port that rosbridge started.

Is there something i am doing wrong or a configuration that i have missed that decrease the overall fps by that much that is unusable?
