Application of gravitation field restriction technology in interactive drawing system

引力场约束技术是交互式构图技术中的一个重要技术,文章介绍了引力场约束技术的基本思想,以及绘图系统中用网格技术实现引力场的方法,并给出了在交互式绘图系统窗口中网格的绘制算法以及引力场约束技术的实现算法,运用引力场约束技术在绘制一些线形类图形时能够实现端点的精确定位,从而提高绘图的准确性。

The restriction technology of the gravitation field is an important technology in the interactive composition technology. The article introduced the thought of the restriction technology of the gravitation field . It uses the grid technology to implement gravitation field in the drawing system and provided the grid drawing algorithm and gravitation field restriction realization algorithm in interactive drawing system window. It uses the gravitation field restriction technology to realize the accurate localization of the extreme point while drawing some line shape figures, thus the accuracy of drawing is improved.
