In this paper, we propose a novel transfer function design technique for multivariate volume rendering. This technique generates a multidimensional transfer function by logical synthesis of variables and transfer functions. This technique enables analysts to extract correlation of variables and to combine multivariate surface and volume shapes. And this technique is implemented in Remote Visualization System PBVR optimized to several supercomputers. An experiment for the multi-phase fuel melting simulation result in the nuclear energy field shows the powerful ability of this technique enough by extracting complex behavior of molten materials.

This seminar serves as a practical guide to Particle-Based Volume Rendering (PBVR) and its Client-Server system, which is one of a promising technique for large-scale visualization. Remote visualization using Commodity software takes a long time from a few hours to few days because of the explosive increase of the original data or polygon size, however PBVR enables interactive visualization by using pixel-based particle data on the client-server system. PBVR is developed as cross-platform and run on various supercomputers such as K computer, or user PC. Flexible GUI is implemented for analytical visualization for multivariate data. The goal of this course is to learn principle of PBVR and integrated particle-based visualization by using open-source PBVR system through lectures and demonstration.
