In this paper, the author had analysed the thinking of algorithm of the traditional space buffer generation,compared the implementation of the algorithm, and given The summary of the aberration and the buffer distortion.kinds of issues are arised in the process of the implementation of the algorithm.such as the computing speed of algorithm,sharp comers,depression.%本文通过对各类空间缓冲区生成的算法思想及算法实现进行分析与比较,给出了避免在缓冲区生成结果的过程中出现的失真与尖角等问题的最适合的解决方法。
