摘要
针对分形动画中吸引子出现的断裂、失真及特征不明显等缺点,在点变换算法的基础上提出点变换的匹配原则、连通性控制方法以及插值算法.点变换的连通性控制方法可以有效地控制吸引子变形中的连通性,避免吸引子出现断裂现象;路径插值算法可以通过改变吸引子的运动路径,解决吸引子变形中的消失、失真等问题.实验结果表明:该理论可以解决已有方法中存在的一些缺陷,能够得到更加逼真、自然的分形动画效果.
Aimed at the shortcomings of the attractors in fractal animation such as the distortion,rupture,and feature degradation of the images,a matching principle of the point transformation,the connectivity control algorithm and the interpolation algorithm based on the point transformation algorithm were presented.The connectivity control algorithm for the point transformation could be used to control the connectivity of attractors effectively and avoid the happening of the phenomenon of the rupture;Path interpolation algorithm could be used to solve the problem of distortion and disappearing by means of changing the motion path of the attractors.The results of the experiment indicated that this method could solve some defects in the existing methods and could get more lifelike and natural fractal animations.
