【摘要】 采用一些传统算法压缩三维图形数据时,发现压缩比虽高,但是在压缩过程中很容易忽略那些相对于整体变化细微而局部变化激烈的子区域,而且对于曲线的微小变化很敏感,以致于重建效果不理想。本文以曲率作为判据,克服了上述缺点,能对于上述区域尽量加以保留。实验数据表明,压缩后的重建效果较为理想。更多还原

【Abstract】 It is found that though having high compression rates, the traditional algorithms ignore the areas whose variance are relatively small compared to the whole but great compared to the local,and behave sensitively to the small change of curves. And thus undesirable reconstructing results are made. In this paper, the curvature of the curve is used as the judgement to surmount the above disadvantages and keep the above areas as possible. The experimental result shows that an ideal reconstruction of the compressed data is achieved.更多还原
