Abstract

In this study, we have a research of the navigation mechanism in virtual scene and its three model avatar application. Scene navigation is a very important aspect in virtual environment construct. When running VRML, we assume existence of an invisible viewer avatar in the scene. We can take this advantage for conducting collision detection. Paper first studied scene navigation mechanism in VRML, mainly about Navigation Info node and its field’s value significance. Aiming at WALK, FLY, EXAMINE, ANY and NONE navigation type, we discussed theirs concrete application method and effect. Finally, incorporation with a 3D virtual scene example, study gives some research report about avatar Size space cylinder application.
