Poisson-disk sampling

WebThe Stochastic Sampling technique aimed to improve upon the issues of aliasing by allowing for noise instead; however, the paper focused on using the jitter of a regular grid to implement the sampling. Like actual Poisson Disk Sampling, jittering is well suited for image-rendering algorithms and removes some aliasing; however the results are ... WebA more æsthetically pleasing pattern can be generated using Poisson-disc sampling, where no points are less than a minimum distance apart. This produces spectral characteristics similar to blue noise, i.e. less clusters of high and low density..
