Color Banding
A simple D3D12 sample application that demonstrates how to use white and blue noise to dither, mitigating color banding when rendering in SDR. To learn more, see the blog post at: http://www.visualextract.com/posts/color-banding/
After building and running the code, first thing I recommend you do is load up the Nsight Graphics project file (ColorBanding.nsight-gfxproj), and capture a frame of the application running. This will provide a clear view of exactly what is happening as the application is running. Download Nsight Graphics here.
