Abstract: Eonstudio is a most perfect virtual reality language. By using Eonstudio technology, the virtual human-computer interaction machine is built to avoid the damage of expensive equipments and reduce cost, which can also be applied to the training system of expensive equipments. The key technologies are real model construction and dynamic simulation interaction. Firstly the technology of map unwrapping and rendering to textures are used to build more real virtual three-coordinate measuring machine. Then the Eonstudio technology is developed to realize the human-computer simulation interaction. Finally the model of windows sockets are selected to realize the information communication between the two computers. Thus the virtual three-coordinate measuring machine is built. A prototype system is implemented to testify its applicability and validity.

Key words: computer application, virtual reality, Eonstudio technology, three-coordinate measuring machine
