摘要
随着现代计算机信息技术的不断发展,计算机图形学成为学术界研究的热点,尤其是人体关节约束的运动建模,其在社会多个领域中均有着不同程度的应用。作为人体运动关键技术,逆向运动学方法对于运动实时建模有着重要的作用。研究给予人体骨骼关节长度对传统循环坐标下降算法予以改进,其产生的运动效果自然流畅,将生物分子运动模拟的SHAKE算法引入其中,提升了短距离运动建模的效果。在此基础上对多个节点同时运动的解析算法进行模拟,得到多个节点共同作用下的人体运动仿真。与运动捕捉实测数据比较,该算法结果在视觉效果上具有一定的相似性,具有较高应用价值。
with the development of modern computer information technology,computer graphics is becoming a hot spot of academic research,especially the movement model of the human body joint constraints. In many fields,which has different degree application. As a key technology of human motion,reverse kinematics method plays an important role in real-time modeling of motion. The traditional circulation drops coordinate algorithmon human bone joint length is improved,and its movement effect nature is fluent. SHAKE algorithm of biological molecular motion simulation of improved the effect of the short distance movement model. On this basis,the analytic algorithm of simultaneous motion of multiple nodes is simulated,and the simulation of human motion under the joint action of multiple nodes is obtained. Compared with the measured data of motion capture,the results of this algorithm are similar in visual effect and have high application value.
