Rand glsl
Webb在glsl中通过取巧的方式生成随机数其实是一个伪随机的过程。 在实验过程中使用一维随机数生成函数会发现使用 sin 函数在-1.5707和1.5707上会有较大波动。 Webb31 okt. 2024 · 那么，怎么找到这些次级光源呢？这就用到了 shadow map 的思想： 阴影生成 pass：在光源摄像机渲染 shadow map （往往只记录了深度）的时候，顺便额外记录 世界坐标 \(x_p\) 、法线 \(n_p\) 、 接受的直接光源 radiant flux \(\Phi_p\) 。 那么就可以认为 shadow map 的一个 texel 对应一块patch ，从而这张 shadow map 就 ...
