The simulation uses the physics from the gazebo and renders the scene with OSG. Now I need to project a green laser (vertical or horizontal) from the robot, inside the scene. I have no idea how to do something like that (and have almost 0 experience with OSG). Can someone help me? Any help is welcome (suggestion, links, specific tutorials, GitHub repositories, videos, etc...), I tried to find some code but didn't help so much.<br>
<br>
So, I'm completely lost :o<br>

<br>
Thank you!<br>

Cheers,<br>
