提出了一种有效的实时软阴影算法。该算法首先从光照视图生成阴影贴图，然后将场景渲染到屏幕缓冲区纹理中，而不是真实的屏幕。然后，使用百分比更近距离滤波(PCF)来去除阴影边缘的混叠，最后使用高斯滤波器对屏幕进行模糊处理。结果表明，该算法不仅产生了良好的软阴影，而且对动态场景具有实时效果。
An effective real-time soft shadow algorithm is presented.First,the shadow map from the light view is generated.Then the scene is rendered into a screen buffer texture rather than the real screen.Next,the percentage closer filtering (PCF) is used to remove the aliasing on the edge of shadow.Finally,the Gaussian filter is used to blur the screen.The results indicate that the algorithm not only produces a good soft shadow,but also has real-time effect for dynamic scenes.
