三维模型轮廓线探测技术的研究与实现

Research and Realization of Silhouette Detecting Technique for 3D Modeling

在计算机图形图象领域中 ,非真实感绘制 (Non photorealisticrendering ,简称NPR)技术近几年逐渐成为人们研究的热点 ,利用非真实感绘制技术可以生成图象的艺术效果或卡通效果 .本文介绍了探测三维模型轮廓线的一些理论和算法 ,在研究的基础上给出了一种综合探测轮廓线算法 。

Non photorealistic rendering (NPR) has been a popular topic of research in computer graphics recently. Pictures and images with artistic and cartoonistic effects can be created with NPR. In this paper, the theory and algorithm of 3D modeling silhouette detecting are introduced, and on this basis, a general algorithm for silhouette detecting is derived with satisfactory result on testing.
