Abstract: Scientific visualization is a process which involves massive data sets and highly intensive computation.Traditionally, it has been applicable and practicable by means of parallel techniques.With the increasing developments of computer hardware and network technologies, the hardware platform of parallel visualization has shifted from high-end parallel computers and graphics workstations to PC clusters and network connected PCs.Together with the tremendous evolution of the Internet, visualization applications began to utilize resources and provide services over the Internet.As an enabling technology for Internet wide distributed computing, grid favors a new research direction, i.e., grid-enabled visualization.In this paper, the state-of-the-art of grid-enabled visualization is surveyed and a Java-based grid-enabled visualization prototype GVis is proposed.This case study is a preliminary attempt to enable resource conglomeration, task coordination and user collaboration of visualization tasks by utilizing grid technologies.
