AbstractBased on the workshop on Scientific visualization held on Aug 7-91995 at Fermilab, and practical experience with IRIX Explorer, we comment on the use of Open-GL based tools for Event Displays and related HEP data analysis. While Computer Graphics has been used widely in High Energy Physics (HEP) for many decades, scientific visualization is now a well-established technique used in other disciplines, such as chemistry and bio-medicine. HEP can take advantage of this technology, for instance, Event Displays should no longer considered as static graphical application, but as dynamical HEP visualization examples.
However, some of us are not buying into large, powerful visualization systems such as AVS, IBM Data Explorer or IRIX Explorer (now NAG-Explorer) but instead are chosing to use smaller, freeware packages such as GeomView or Vogel, that do not provide the full capabilities of OpenGL, but can run on simple X-terminal. To add more confusion, the current official standard for 3D Event Displays at CERN is based on PHIGS, which is incompatible with the systems mentioned above.
We wish to compare the pro and cons of such systems on technical ground, ease of use, and most of all, application interfaces, as the programmer and the user are often the same person. Costs and educational considerations will also be briefly discussed.
