SUMMARY
The Internet has a growing importance as a medium for presenting 3D visualization and is offering visualization tools. In this paper, we identify requirements for 3D visualization systems to interactively visualize user data. We analyzed four possible solutions: VRML, Viewpoint Experience, Cult3D and Virtue3D technology. We tested quality of visualization, interactivity, software support, size of files. Based on the defined requirements and comparison of the research parameters, the optimal technology for presentation of 3D models on the Internet will be selected.
