Creating a roundabout (Ignition)

Hi everyone,

I would like to ask for help on my project I'm going to start working on in Ignition, I'm pretty new in "Gazeboworld", so please forgive my shortcomings. The project is to make a copy of a real world roundabout, so it would be possible to test different robots in this environment. At the top of my head I think my first step should be constructing a ground plane. What is the best way to approach this task? I actually have LIDAR point clouds of the roundabout as well, so maybe that might be useful? So my question would be: How can i create a ground plane in Ignition, that would be the closest to the real world ground (land) plane?

I am open to any suggestions or criticism that would help me with my project.

Thank you in advance!

You could import a 3D model of a roundabout. Similar to this one:

If you don't need any height information, for example, if you don't care about the sidewalk around it, you could just use a texture on a ground plane. But that may not give much information for your lidar.

I suggest you take a look at the SDF spec and this tutrorial about visuals.

In the car_demo project of openrobotics they use a roundabout. Maybe this works for you?
