2015年9月24日 — The code posted above is a stripped down version of a bigger shader. My understanding is that passing an element of a sampler2DShadow array as ...

2005年7月10日 — If you just want to read the depth value, it's probably safer to use texture2D instead of shadow2D. shadow2D reads the depth value like ...

2022年7月28日 — The usage of sampler2DShadow does not work since it requires a special texture parameter ( gl.TEXTURE_COMPARE_MODE ) to have a specific value ( ...

I've been trying to implement percentage closer filtering for my shadow mapping as described here Nvidia GPU Gems. When I try to sample my shadow map using ...

2019年12月3日 — I want to iterate through an array of sampler2DShadow for a shadow map computation (multiple lights), and it looks like the sampler can be ...

2014年3月15日 — There are three things you must do to generate a depth from a world-space position: · Multiply the world-space position by your (light's) ...

2020年12月11日 — Note that shadow sampler types do not add an additional coordinate to gradvec​, so a sampler2DShadow is still vec2. This function works ...

因为，sampler2DShadow 表示四个点的比值，而sampler2D 只能得到一个单一的平均深度和一个布尔型，这对阴影锯齿来说并不理想。 阴影采样器的一个常用场景就是shadow map。
