Hi folks-

We (at Willow) have started writing some plugins to Rviz to allow use of a 3D/6D cursor (such as might be provided by a haptic device or Razer Hydra device).

While the plugin and cursor side of all this is still highly unstable, I'd like to make some minor (non-breaking) additions to the InteractiveMarkerControl definition in anticipation of supporting 3D control.

Please reply to this thread and/or put comments on the wiki if this is of interest to you.
I'm hoping this is a minor enough change that we can push it within a week so it makes it into Groovy...

Cheers,
