Abstract
Funded by National High Technology 863 Project, the distributed virtual environment network DVENET has been focused at incorporating realistic 3D visual simulation into a joint exercise. Visual tracking allows visual simulation to measure visual field and visual angle relied on by multi-resolution rendering techniques including LOD (level of detail), morphing and LOL (level of light), which economize the computational cost. Based on vision perception of user, this paper describes our recent research in real-time multi-resolution rendering of 3D models in virtual environment. This method calculates the critical parameters, such as view-distance, imaging parameter, brightness parameter, and so on, which control the switches between neighbor multiple resolution models and are correlative to user’s visual field and visual angle. It might also be utilized for kinds of simulators responding to the presence of the multi-resolution target but based on the special visions of infrared equipment or radar.
