### Get your bearings in SOFA

Description:

To identify the axis of the 3D scene, we can display them with the component OglLineAxis

We add the component OglLineAxis in the scene file. With the '@' symbol, we create a link between the size of the grid and the size of the axis.

- The red axis corresponds to x (the first coordinate in a 3d vector)
- The green axis corresponds to y (the second coordinate in a 3d vector)
- The blue axis corresponds to z (the third coordinate in a 3d vector)
