[vtkusers] How to avoid actors resizing when camera zooms?????

[Mathieu Coursolle]

Hi,
I need to draw some cubes into a 3D image. However, the visible
size of those cubes should not change to the user when the camera
moves or zooms. Those cubes should have a specific 3D world coordinates but size should be set according to the viewport size
at all time.
I'm really out of idea here...if anyone could help me with this it would
really be appreciated.
Thank you.
 
MAthieu
