SpletPCSS Percentage Closer Soft Shadows（PCSS）是基于 PCF 的一种改进型软阴影算法。正如其名，PCSS 考虑了遮挡距离和阴影模糊度的关系，并通过合理的建模给出视觉上 persuadable 的结果。刚刚我们讨论到遮挡距离决定了阴影的模糊程度，而不同的 filter 半径可以生成不同模糊程度的阴影。于是一拍脑袋很容易想到 PCSS 的工作流程：确定一个 … Splet2 Principle of the PCSS algorithm. The algorithm of PCSS for two-dimensional PTV system is described as follows. Assume that we have obtained the locations of particle centroids in two successive frames after image processing. i. is an object particle in the ﬁrst frame at time. t. as shown in Fig.1(a). The aim of PCSS is to identify the ...

SpletSoft Shadows (PCSS) algorithm [Fernando 05] is an extension of PCF which can render physically-plausible contact-hardening shadows. Like PCSS, Multi-View Soft Shadows (MVSS) uses a depth bias to avoid self-shadowing artifacts (surface acne), by pushing the shadow-map fragments away from the light source. Splet接下来跟PCF一样，我们计算要filter的部分，PCSS本质上就是求出了阴影中需要做PCF的半影部分后再进行PCF的计算，这样动态调节了半影范围，也就是动态设置了PCF的搜索范围，这样我们的硬阴影部分清晰，软阴影部分模糊，动态的实现了不错的软阴影效果。. 以上 ...

"SpletThe Percentage-Closer Soft Shadows (PCSS) algorithm computes a variable kernel size based on the distance between the relative position of the receiver point, an approximation of the blocker, and the area light. It produces perceptually plausible soft shadows that harden on contact (see screenshot above). " - Pcss algorithm

SpletThe shadow-mapping algorithm came to computer graphics in 1978 when it was introduced by Lance Williams (Williams 1978). Today, this method is used in a multitude of Hollywood movies that contain computer graphics and special effects. Shadow mapping projects a special dynamically created texture on scene geometry to calculate shadows.
