RE: [ROOT] Setting Viewpoint in TView and/or X3d

Hello  Ben,

This can be done with Qt-based ROOT version where both kind of 3D
viewers the  X3D as well  as the OpenGL one are made the QWidgets. This
implies the end-user code can communicate these widgets directly using
Qt Signal/Slot mechanism.

Further details are available from http://root.bnl.gov

  My best regards, Valeri
