基于圆域的图形绘制方法

通过研究基于点的计算机真实感绘制技术,提出了一种新的造型绘制方法———基于圆域的图形绘制方法。该方法不同于传统的网格造型,而是仅以三维物体上的点进行造型,并将点扩展成圆作为基本绘制元素,通过剔除背向点、投影和平滑填补空隙等操作得到物体的真实感图形。该方法数据结构简单、存储空间小、绘制速度快且易于实现,并且能获得较高的真实感效果。

Drawing technique based on circle-field

On the basis of research on the computer reality sense drawing technique based on the point,a new drawing technique based on the circle-field was proposed.Differing from the traditional drawing technique based on the mesh,the new technique uses the points on the 3-dimensional object to construct a model.The points then are expanded to circles to form the basic drawing elements,and a realistic image can be obtained by removing back-points,projecting circles onto screen and filling gaps smoothly.The proposed ...
