| Abstract: | Collision detection is an important part of virtual environment walkthrough.The exact and real-time collision detection can enhance the reality of virtual environment,improve the immersion of system user.In this paper,we present the collision detection based on eye-position and improve it to realize terrain follow in walkthrough.Practice shows that the method presented in this paper can meet our requirement.At last,we present the method of optimizing the arithmetic. |
