Abstract
Scientific Visualization, the application of computer graphics techniques to produce pictures of complex volume image and physical phenomenon, is emerging as a very powerful means of enabling scientists and researchers to interpret their data. The theories of image generation have been investigated over 2O years, however, most conventional computer graphic techniques are optimized for well organized data base elements such as polygon. In most application of scientific visualization, source data to be visualized are pre-organized data set such as volume metric data and many new techniques have been developed last 10 years. These techniques are generalized to volume rendering method. In this article, I would like to introduce volume ray tracing methods to visualize three dimensional and four dimensional volume metric data. The results of visualization from medical images are shown.
