Research On Model And Roam Technology Of3D Scene Based On WEB

Virtual roam technology is a significant component of the Virtual real technology, and itwas developed in many professional area fastly. With the network technology developmentwidely and technology development, this is made possible to apply the Virtual roamtechnology applied in network is possible. For the purpose of applying the key technologiesof construction virtual roaming system,this paper is established on the research modelingtechnology,texture anti-aliasing and Collision Dectection.Firstly,this paper research on the modeling technology of Virtual Walk-throughSystem.This paper discusses the virtual reality related technology, and the modeling method,the code-reusing(DEF/USE),multi-resolution level of detail (LOD), the scene optimizationtechniques and so on.Secondly,this paper discusses the texture mapping. The dissertation discusses theproblem of texture anti-aliasing.Then based on the data structure of the system,This paper makes the research onCollision Dectection,Combined the AABB and Triangle collision detection algorithm, givesthe corresponding realization method.Finally, a prototypical system of building environment is designed which is based onkey technology.The results of these examples indicate the correctness and credibility of thealgorithms above.
