摘要:
碰撞检测是虚拟场景的核心技术,其效果的好坏直接影响整个虚拟场景的真实感。基于OSG（OpenSceneGraph）三维场景渲染引擎和Multigen Creator三维可视化仿真建模软件,采用包围盒碰撞检测算法,实现了多个静态物体与动态物体的碰撞检测,通过使用射线检测算法可以很好地解决静态物体与地面以及动态物体与地面的碰撞检测。为了满足实时性的要求,提出了多个静态物体与动态物体的碰撞检测优化算法的数学模型。结果表明,算法具有很好的有效性和快速性,能够满足要求
Abstract:
Collision detection is the core technique of virtual reality,the effect of it impacts on realism of virtual scene directly.Based on OSG three-dimensional scene rendering engine and Multigen Creator three-dimensional modeling software,achieved collision detection of a number of static and dynamic objects by using the bounding box collision detection.Ray detection algorithm was proposed to realize collision detection of many static objects and ground as well as dynamic objects and ground.In order to meet the requirements of real-time,the optimization model was put forward for a number of static and dynamic objects in the collision detection algorithm.The result shows the algorithm can meet requirements with validity and rapidity
