In this web content, the author discusses the design of noise in frequency space for computer graphics. They explain the concept of blue noise, which is random noise that prefers to alternate between different values and avoid long runs of the same value. Blue noise is commonly used for dithering in computer graphics because it tends to disappear when viewed from afar or blurred. The author describes their process of generating blue noise using a specialized algorithm called the swap algorithm. They also discuss the challenges and techniques involved in speeding up the generation process. Overall, the content provides insights into the complexities of designing noise in frequency space for computer graphics.
