WebAug 8, 2015 · Poisson disk sampling is an important problem in computer graphics and has a wide variety of applications in imaging, geometry, rendering, etc. In this paper, we propose a novel Poisson disk sampling algorithm based on disk packing. The key idea uses the observation that a relatively dense disk packing layout naturally satisfies the … WebApr 1, 2024 · In [15], Bridson described a fast O n algorithm for generating a poisson-disc sampling pattern with a constant density. In [16], Tulleken adapted this algorithm to accommodate a variable density sampling pattern based on a priori knowledge of the maximum poisson-disc radius parameter. Tulleken's method is O n 2. Notably, this …
