Virtual Table Tennis Competition In The Virtual Arena Crowd Modeling And Rendering

In recent years, with the vigorous development of the virtual reality technology, virtual human is widely used in many fields. Introducing the virtual human technology in sports simulation and constructing a highly immersed sense of virtual stadium environment can enhance the sports training pertinence and provide the technical support for athletes training. It has very important meaning for improving the modern sports training level to research modeling and rendering of the virtual crowd in the table tennis competition.This paper first studied geometry modeling, movement modeling and emotional modeling method of the virtual human. According to the characteristics of all kinds of audiences in the virtual table tennis competition, this paper modeled the virtual people and formed a virtual human model library. And then did a research on the virtual human group modeling. It focused on the group cooperative behavior modeling method. Put forward the audience group concerted behavior rules based on the table tennis competition environment, and did a simulation experiment to verify it. This paper studied the virtual human emotions model, and proposed a kind of particle system based on the emotion of the modeling method. This paper analyzed the real-time rendering methods and virtual crowd collision detection problems. Did the experiments that based on the OSG graphics engine for the competition environment of the collision detection, and get good experimental results. Using the Delta3D simulation engine, virtual crowd modeling and rendering technology to design and implement the virtual table tennis competition system, and also implemented the realistic table tennis competition playing virtual environment.
