摘　　要：针对目前眼睛肌肉动画模型不够真实,细节表现不够逼真,提出了一种改进的基于肌肉模型的眼睛动画算法,通过设置眼部范围向量和眼部肌肉三维方向上的影响因子,优化了眼部肌肉运动模型,提高了运算速度,并根据眼皮运动的特殊性,单独对眼皮采用了一种高效的算法模型,此方法首先对眼皮标注特征点,然后将眼皮运动模拟为眼皮顶点沿两眼角为轴的上下运动,根据眼皮运动的规律,算出不同位置顶点的旋转角度,采用插值方法计算新的顶点,实验结果表明该算法具有较好的细节表现,生成的眼睛动画逼真。At present,the model of eye muscle animation is not real enough and the representation of detail is not realistic enough. In order to resolve this problem,an improved algorithm of eye animation based on muscle model was put forward. This method optimized the eye muscle movement model and increased the computing speed by setting the eye area vector and the influence factor of the 3 dimension directions in eye muscle. Based on the particularity of eyelid movement,a more efficient algorithm model was adopted on the eyelid separately. Firstly,this method labeled the features,and then simulated the eyelid movement to the up and down movement of the eyelid vertex around the axis of two eye corners and computed rotated angles of the vertexes in different positions based on the law of eyelid movement,finally computed the new vertex using interpolation. The experiment result indicates that this algorithm has better detail representation,and the created eye animation is realistic.
