摘　　要：将LOD思想应用于运动捕获数据驱动骨骼运动,运动捕获数据采用BVH格式;提出利用关节点的旋转信道计算帧差距,生成和控制不同层次的运动LOD模型;采用几何重定向的方法进行运动数据重定向;将运动LOD分为离散LOD和连续LOD两类,并分别给出简化方法.实验结果表明:对于关节点,在其动作不明显的帧中,被简化的机会较大;在其动作相对重要的帧中,该关节点能够被重新渲染出来,基于帧差距简化的视觉效果较好.Applying LOD to motion capture data driven skeleton animation,BVH format is used for motion capture data.Based on this we proposed computing the frame distance by the rotation channel of joint to generate and control the different motion LOD model using the geometric retarget methods to retarget motion data.The motion LOD was classified into discrete LOD and continuous LOD,producing the simplified method separately.The result of experiments showed that the simplified chance of joint in the frame with less obvious action was high,and in the frame with important action,the joint would be re-rendered.As a result,using the frame distance to simplify can achieve better visual effects.
