Visualization of scientific computation, a research field newly emerged over the past few years, uses the computer graphics and image processing technique to convert the data and computation results produced in the process of scientific computation into interactive and viewable graphics or images, which brings forth significant revolution to computer application and scientific computation method. This paper presents the general situation of the development in the Visualization technology and its significance. Case studies demonstrate its application in medical care, meteorology, architecture, mechanical calculation, simulation and modeling and CAD. Also in the paper are presented the prominent advantages of scientific visualization in practical application, as well as the commonly used methods and techniques for visualization. A preliminary prediction is given of the application prospects of the technology in China's mining industry.
