【摘要】 针对以往重建表面算法的复杂、计算量大以及存在误连而导致走样等不利因素,提出一种基于角度的三角面片联结方法。该方法主要是在面片联结之前对轮廓线上的点按角度进行取舍,不仅减少了要处理的数据点,而且也使三角面片的联结简易化。实验表明,该方法简单易行,重建速度快,计算量小,适合于由序列单轮廓线重建三维表面形体。更多还原

【Abstract】 In view of the disadvantages in the algorithms for reconstructing 3-D surface, such as the complexity, so high computational cost and distorting, a triangular patch joining method based on angles is proposed in this paper. This way accepts or rejects the contour points by their angles before the patch joining, so that decreases the amount of data to be processed and makes the patch joining easier. Some experiments show that this method is easy to realize and has higher reconstructing speed and less computational cost, so it is suitable for reconstructing 3-D surface from serial 2-D single contours.更多还原
