【摘要】 真实感图形显示是计算机图形学的一个重要组成部分。扫描线算法是一种常用的真实感图形显示算法。文章在扫描线直实感图形显示算法基础之上，对其作了一定的改进。对光照模型增加了衰减变化，并使扫描线算法也适用于曲面，提高了真实感的效果。更多还原

【Abstract】 Realistic representation is a main part of computer graphics and the scan-line algotithm is an ordinary algorithm for realistic representation. This paper presents an improved algorithm based on scan-line algorithm. The algorithm is able to adpat to curve surface and also adapt to light attenuation.更多还原
