Gaussian blue noise

AGM Ahmed, J Ren, P Wonka - ACM Transactions on Graphics (TOG), 2022 - dl.acm.org
Among the various approaches for producing point distributions with blue noise spectrum,
we argue for an optimization framework using Gaussian kernels. We show that with a wise …

Scalable multi-class sampling via filtered sliced optimal transport

C Salaün, I Georgiev, HP Seidel, G Singh - arXiv preprint arXiv …, 2022 - arxiv.org
We propose a multi-class point optimization formulation based on continuous Wasserstein
barycenters. Our formulation is designed to handle hundreds to thousands of optimization …

Matbuilder: Mastering sampling uniformity over projections

L Paulin, N Bonneel, D Coeurjolly, JC Iehl… - ACM Transactions on …, 2022 - dl.acm.org
Many applications ranging from quasi-Monte Carlo integration over optimal control to neural
networks benefit from high-dimensional, highly uniform samples. In the case of computer …

Analysis and synthesis of digital dyadic sequences

AGM Ahmed, M Skopenkov, M Hadwiger… - ACM Transactions on …, 2023 - dl.acm.org
We explore the space of matrix-generated (0, m, 2)-nets and (0, 2)-sequences in base 2,
also known as digital dyadic nets and sequences. In computer graphics, they are arguably …

ART-Owen Scrambling

AGM Ahmed, M Pharr, P Wonka - ACM Transactions on Graphics (TOG), 2023 - dl.acm.org
We present a novel algorithm for implementing Owen-scrambling, combining the generation
and distribution of the scrambling bits in a single self-contained compact process. We …

[PDF][PDF] Stochastic Generation of (t, s) Sample Sequences.

A Helmer, PH Christensen, A Kensler - EGSR (DL), 2021 - diglib.eg.org
We introduce a novel method to generate sample sequences that are progressively stratified
both in high dimensions and in lower-dimensional projections. Our method comes from a …

Curl Noise Jittering

JA Bærentzen, JR Frisvad, J Martínez - SIGGRAPH Asia 2023 …, 2023 - dl.acm.org
We propose a method for implicitly generating blue noise point sets. Our method is based on
the observations that curl noise vector fields are volume-preserving and that jittering can be …

Example-Based Sampling with Diffusion Models

B Doignies, N Bonneel, D Coeurjolly, J Digne… - SIGGRAPH Asia 2023 …, 2023 - dl.acm.org
Much effort has been put into developing samplers with specific properties, such as
producing blue noise, low-discrepancy, lattice or Poisson disk samples. These samplers can …
