Splet08. sep. 2024 · 本文源自PBRT的一个课后习题 1.1概述 在只有一小部分被照亮的表面可以在渲染图像中看到的场景中，SPPM变得比较低效。这种问题对各种光子映射算法都是存在的，自适应光子映射算法则可以较好的解决这种问题。其核心思想是定义一个光子路径的visibility function并根据这个可视函数进行重要性采样。 Splet04. mar. 2024 · 在PBRT中进行采样一般是在标准区间如$[0, 1)^2$上进行的，而在实际计算积分时往往需要会对区间进行缩放，这就导致了原始区间上均匀分布的样本在缩放后产生一定的扭曲。以下图为例，(a)图表示从$4\times4$区间上进行分层抽样然后缩放到长方形区域的样本，而(b ...
