Syntax RGB = tonemap(HDR) RGB = tonemap(HDR,Name=Value)Description RGB = tonemap(HDR) converts the high dynamic range image HDR to a lower dynamic range image, RGB, suitable for display, using a process called tone mapping. Tone mapping is a technique used to approximate the appearance ...
Example: RGB = tonemap(HDR,AdjustLightness=[0.05 0.95]) adjusts the lightness of the rendered image such that pixel values between 0.05 and 0.95 linearly map to display values between 0 and 1. Before R2021a, use commas to separate each name and value, and enclose Name in quotes. Example...
PostProcessTonemap.usf 是UE4 后期的总Shader,类似Unity 中的Uber,其中MainPS() 是PC平台 PixelShader入口,MainCS() 是ComputeShader 入口。 在Pixel 流程下,直接输出,0.5,Ctl+Shift+. 可以看到,屏幕上的颜色是0.5。 这个确实是我们想要的。 // pixel shader entry point ...

Filmic tonemap(电影色调映射)是将HDR色域映射到LDR色域(D5里面就是Linear 到 sRGB)的优秀解决方案,由John Hable老哥发扬光大,是早已在VR和CR渲染器中提供的功能,希望D5早日在后期中加入这么重要的功能。 image1440×1195 129 KB 这位老哥在他的博客里面很详细的介绍了Filmic tonemap的原理,http://filmicworlds...
tonemap Tonemapped Tone Mapping原是摄影学中的一个术语,因为打印相片所能表现的亮度范围不足以表现现实世界中的亮度域,而如果简单的将真实世界的整个亮度域线性压缩到照片所能表现的亮度域内,则会在明暗两端同时丢失很多细节,这显然不是所希望的效果,Tone Mapping就是为了克服这一情况而存在的,既然相片所能呈现的...
