基于物体纵向扫描线的计算机三维物体绘制技术

3D Drawing Technique Based on Three-Dimensional Vertical Scanning Lines

计算机技术的高速发展使绘制三维复杂场景成为现实。目前有很多三维物体的绘制方法,但都是先扫描,再进行显示观察的。文中所讨论的基于物体三维纵向扫描线的计算机三维物体绘制技术,是一种适应实时扫描显示功能的绘制技术。由于它是以物体的纵向扫描线为绘制的基本单位,所以可以边扫描边进行显示。根据研究结果,可以利用已得到的物体的纵向扫描线绘制出完整的三维物体。

Increasing computing power has opened the door to 3D scene complexities that were unimaginable a decade ago. Now there are many methods to draw three- dimensional objects,but the conventional way is to scan object firstly, then draw the picture. So Discusses the 3D drawing technique which is based on three- dimensional vertical scanning lines. It＇s a technique fit in with real time displaying. Because its basic drawing unit is the object＇s vertical scanning lines, the 3D objects can be displayed while scanning. Based on the result of the research,the complete 3D objects can be drawn by vertical scanning lines of the 3D objects previously obtained.
