适用于复杂动态场景的快速阴影算法

3D场景中阴影的使用可以提高图像的真实感,文章详细的分析了平面阴影算法和阴影体算法两种阴影算法原理,并给出了数学推导和实现方法。综合使用这两种算法,借助碰撞检测技术中的包围盒原理,文章提出了适用于复杂场景阴影快速算法,还针对动态场景光源变换逆矩阵求解复杂的问题,给出了一种快速确定光源位置的求解方法。经试验证实,该算法既能够较为真实绘制阴影,又缩短了绘制时间,提高了效率。

Fast Shadow Algorithm for Complex Dynamic Scene

Use of 3D scene in the shadow of the reality can improve image,this paper analysis of the planar shadow algorithm and shadow volume algorithm,and present the principle and realization method of mathematical deduction.Comprehensive use of these two kinds of algorithms,collision detection technology in the bounding box principle,this paper put forward the shadow fast algorithm suitable for complicated scene,and also for dynamic scene light inverse matrix transformation of solving complex problems,this paper presents a rapid determination of the source of the solution.Experiments show that the algorithm can draw shadow,and improving the efficiency of drawing.
