Is there any methods for display the vtk 3D axes at a specific place (such as left bottom) on the screen? I have tried to use the vtktransform but it does accepts the coordinates of the world only, but not the screen. Thanks
Do you want something like this?
If yes, then you can use vtkOrientationMarkerWidget
and vtkAxesActor
to do that. Have a look at this link, it might help you.
