Blue-Noise Point Sampling Using Kernel Density Model
A new method for generating spatially varying stochastic-point distributions with blue-noise spec***m in linear time. The method relies on a novel multi-scale strategy that draws samples from an interacting particles statistical model that formalizes the problem.

Efficient Maximal Poisson-Disk Sampling
This paper solves the problem of generating a uniform Poisson-disk sampling that is both maximal and unbiased over bounded non-convex domains. The method is fast, requires little memory, and is guaranteed to terminate without any bias. The paper also demonstrates a parallel GPU implementation that performs MPS in a bias-free fashion.

Differential Domain Analysis for Non-Uniform Sampling
Existing spatial and spectral methods for analyzing sample distributions are restricted to uniform domains. This paper presents differential domain analysis for general non-uniform scenarios including adaptive, anisotropic, and surface sampling, by reformulating standard Fourier analysis that depends on sample locations into an equivalent form that depends on only location differentials.

Filtering Solid Gabor Noise
Existing noise functions either introduce discontinuities of the solid noise at sharp edges (wavelet noise, Gabor noise) or result in detail loss when anti-aliased (Perlin noise, wavelet noise). This paper presents a new noise function that preserves continuity over sharp edges and supports high-quality anti-aliasing.
