How to draw line in viewer3d ?

Hello,

I m trying to use viewer3d as a openGL viewer and it works well for 3D surface and 3D points using images.ui.graphics.Surface and images.ui.graphics.Points but i wonder if it is possible to draw line or connected line inside the viewer ? I dont mean how to show wireframe when using a surface or annotation line.

I just try for exemple to attached 3 vectors in X,Y and Z direction to each 3D object.

I saw 2 functions WideLine and Thinline but i did not find any documentation about them.

Thanks for your help
