摘要
本文研究了一种几何作图输入图形的新方法,它是我们研制的二维、三线造型系统的一个部分。本法的一个显著特点是省略了通常的裁剪过程,在图形元素定义、几何交切和跟踪成环过程中自动裁剪,并可重叠跟踪。
A new method of inputing graphics with geometric graphics is presented. It is characterized by the omission of general clipping operation, thus the user can define graphics elements (point, line, circle) interactively and precisely, acknowledge them to effect intersection and tangent, and trace them to form a 2-D loop data structure.
