摘要
引入了一种直线与三角形求交的简洁算法和区域块投影算法，有效地减少了真实感图形生成中光线与物体的求交计算时间．另外，采用区别对待高光区域和非高光区域等方法，解决了Ｇｏｕｒａｕｄ浓淡算法不能生成高光效果的问题，改善了图形质量．
A clean algorithm for determining whether a ray intersects a triangle, region projection method and hybrid model are presented in this paper. These methods can reduce the time of intersection and accelerate the speed of generation of realistic image. By analysing algorithm and experiments, it is indicated that these methods have better performance than the scan line algorithm. The speed of rendering and the quality of generated image are satisfied.
