[TARRAGO Xavier 103783]

  Hello,

  I'd like to get a 3d representation of a trihedron (i-e Ox, Oy, Oz). I want to show the three arrows (like a vtkAxesActor), but I want it to be always in the bottom-left corner of the viewport, always in front of the scene and with a size fixed in view coordinates. Of course, it will not show the position of origin, but only the axes orientation. It should follow the camera movments.

  Any ideas of how to get this effect?

  Thanks in advance,
