I wish to publish the clicked point in Rviz. I read that we need to be using the ROS navigation stack for this feature to work. However, my setup doesn't use laser scans and relies on aruco markers. Hence, I am not using the navigation stack.

I wish to create a multicolored visualization of a car in Rviz. I am using a Collada (.dae) file with the car's 3D mesh.

I followed the steps here: http://wiki.ros.org/rviz/DisplayTypes....

The shape gets correctly visualized but the colors are ignored and the car is shown in grey. I can add a single color by setting the color parameter of visualization_msgs::Marker in the ros node, but doing so adds the same color to all parts of the car.

Thank you in advance for any suggestion :D

I have a map frame, a camera frame and a robot frame. The transform between map frame and the camera frame is fixed and gets published occasionally, ~10 seconds irregular intervals. The transform between the camera and the robot gets published at ~30Hz. The Rviz visualization of the robot's pose is with reference to the map frame and it gets updated only after it receives a new /tf message for transform between map and camera. I want Rviz to use whatever previous transform is available from the tf tree to create the visualization. Thank you in advance :)

Yes, the same message will be available to all nodes which have subscribed to that message topic. In your case, for the

That was simple and it worked. Thanks! You may add that as an answer if you like.

All transforms are being published based on the detection of Aruco markers using the aruco_ros package (https://github.c
