Title : Visualization of the ROOT 3D class objects with Open
        Inventor-like viewers

Authors : Valeri Fine, Mikhail Panebrattsev, Alexander Kulikov

Abstract : 
The good portion of computational force (and price) of the modern
computer, first of all so-called Desktop PC, belongs its sophisticated
video card with advanced 3D accelerators. So far this vast power did not
play any major role in the High Energy Physics research due lack of the
software that can be feed by the HEP data.

The paper shows the approach and software to represent the ROOT 3D class
objects with the well known text format of the "Open Inventor" package.
This allows to use the commercial quality 3D viewers like "Open
Inventor" both stand-alone  as well as a built-in ROOT 3D viewer to make
the cutting / highlighting / selecting pieces of the detectors and
events fruitful and ease. That would create the impressive pictures of
events and the detail views of the detectors facilitating the design,
simulation and data analysis and representation the huge amount the
information flooding the modern HEP experiments
