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(More)
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. The remote visualization using commodity software takes a long time from a few hours to a few days because of the explosive increase of the original data or polygon size,(More)
In this article, we propose a technique for improving the image quality of particle-based volume rendering (PBVR). A large-scale unstructured volume dataset often contains multiple sub-volumes, which cannot be ordered by visibility. PBVR can handle this type of volume dataset. Sampling misses often occur when the transfer function undergoes drastic changes,(More)
