Re: 3D viewer in ROOT 4.02

Hi Ralf,

 The new viewer TViewerOpenGL is under development. A lot of work is currently put on that tool. The old way (TPadOpenGLView) will not be reactivated, it was unmaintainable and it was not possible to evolve it on the long term. Now we have a common interface for all viewer (x3d OpenGL etc ...). Many new functionalities have been put in the new OpenGL viewer:

• color management,
• transparency,
• possibility to move object,
• vector postscript,
• we are now working on a way to represent the composite shapes,
• a PadGL is also under investigation to have a even better integration of OpenGL in ROOT,
• etc ...

May be you can send us a little script showing how you were using TPadOpenGLView and what are you missing in TViewerOpenGL. We will help you to find a solution.

 Cheers, Olivier
