Perceptual Evaluation of Tone Mapping Operators with Real-World Sceness We observe a clear distinction between global and local operators in favor of the latter, and we classify the tone mapping operators according to ... A Yoshida,V Blanz,K Myszkowski,... - Proceedings of SPIE - The Intern...

Tone mapping is a technique used to map the pixel levels in high dynamic range images to a reduced dynamic range (such as mapping from 16-bit to 8-bit), while still retaining an appearance as close to the original image as possible. Normally the active camera uses adaptive, local tone cu...
Nuke全局色调运算Global Tonemapping Operators 附件是用于实施各种全局色调映射运算符的,可以作为组使用,并可以从一个文件快速复制/粘贴到另一个文件。 当前工具包含以下运算符:Simple, Normalise, Gamma, Logarithmic, Exponential, Schlick (1994) ,Reinhard (2004), Filmic 由于Nuke无法执行图像平均值,最小值和最大...
Color correction is integrated within global tone mapping operations to modify an image captured using an image capture device. New luminance values are determined for the pixels of the image by performing global tone mapping against those pixels using one or more sets of color correction values, ...
以下代码中可以发现,在更新 irradiance 的过程中可以通过引入 maxBackfaces 最大背面的数量,从而为 irradiance 引入local occlusion 的信息。 当probeRayDistance 小于0 的次数 (当前射线在 Trace Probe Rays 阶段与场景中某个物体的背面相交) 超过 maxBackfaces 时,当前的 radiance 便不再计入计算 irradiance 的贡献...
1 背景和原理 全局光照(Global Illumination)的算法或者方案有很多,如IBL/PRT/SSGI/VXGI/DDGI/Lumen/SurfelsGI等等,其根本上就是为了解决间接光照的问题,那为什么需要有间接光呢,仅直接光渲染的效果如下,这里请允许我再次借用下O3DE引擎:-) 上面效果一般在现代引擎中是看不到的,因为通常基于PBR的渲染都会默认再叠加...
