How can I get a dynamic ground plane?

Hi,

I added an image as ground plane but I want it to move with a constant linear or angular velocity. I want to achieve it by changing its pose as function of time.

How can I accomplish this task? Do I have to create a customized plugin? Is it also possible to have a video as ground plane?

Thanks

This tutorial goes over various ways of moving objects in simulation with a given velocity:

Note that if your plane has a collision shape, it will carry the models laying on top of it. You can move just a model that has no collision but has a visual in case you just wan the visual to move.

Another possible way of doing this is with scripted trajectories:

Yes, here's some explanation on how to do it with ROS 1 / 2:

You could also use a texture that changes over time, sort of like a GIF, here's an example:

Thanks for your reply. Anyway I found another solution. I used a transparent static ground plane so that objects on it doesn't move. I placed below it an object with the texture I need and used a plugin to make it move
