| Abstract: | This paper presents a research on the flexible cable modeling method in virtual environment. The discrete control point simple model and the algorithm of calculating the discrete control point coordinate values are given. To the collision detection of flexible cable in virtual environment, both round the side and through the above side of virtual bodies are analyzed. Based on depth vector and bump vector collision detection methods, the collision detection response algorithm is offered. |
