| 摘 要： | 论文实现了为3D角色的每个骨骼构建一个OBB(OrientedBoundingBox,有向包围盒)用于实时动态碰撞检测的方法,并在实现中以MicrosoftDirectXAPI为基础,通过扩展X模型文件模版,将离线计算的OBB嵌入3D关节角色模型免去运行时的计算。该方法较大地提高了3D角色实时动态碰撞检测效率,可应用于第一人称射击游戏、3D角色模拟游戏、机器人寻径以及虚拟战术环境中。

| Abstract: | This paper implements a real-time dynamic collision detection method for 3D articulated character by constructing an OBB(Oriented Bounding Box) for each bone inside.Based on the APIs of DirectX,the templates of the X model file are extended and the off-line computed OBB are embedded into the articulated 3D character model to remove computation in runtime.This method can be applied to the FPS(First Person Shooting) game,3D Character simulation game,path-finding in Robotics as well as virtual tactics to improve efficiency of 3D articulated character collision detection. |
