摘要
为了提高数字皮影动画的真实性以及实时性,降低数字皮影动画制作难度,对数字皮影模型构建进行了抽象和简化,并根据数字皮影动画中的造型特点将抽象骨骼进行编号、分类处理,并设计出适用于数字皮影动画的骨骼模型;在此基础上,提出了一种对解算过程进行改进的二维逆运动学问题解决方法。结合实例,对模型和算法进行了仿真分析,实验结果表明,该方法有效的降低运算成本,并提高动画控制的实时性。
To improve the authenticity and real time of the digital shadow play animation, reduce digital shadow play ani- mation manufacturing difficulty, the digital shadow play model is abstract and simplified according to the characteristics of digital shadow play animation. The character model is abstract to skeleton and classified to apply to the digital shadow play animation; Based on cyclic-coordinate descent algorithm, a solution to improve the efficiency of 2D inverse kinematic is proposed. Finally, the experimental results show that this method is effective reduce system cost and achieve real-time control.
