Starting from a template low-discrepancy (LD) point set (a), we use a segmented table of permutations to rearrange the LD set to match a reference set with the desired target spectrum (b). The permutations are localized and carefully constructed in such a way that they have minimal impact on the discrepancy of the underlying template set. The resulting set (c) inherits the spectral profile of the target set, while still retaining the discrepancy profile of the template set (d).


We present a novel technique that produces two-dimensional low-discrepancy (LD) blue noise point sets for sampling. Using one-dimensional binary van der Corput sequences, we construct two-dimensional LD point sets, and rearrange them to match a target spectral profile without loosing their low discrepancy. We store the rearrangement information in a compact lookup table that can be used to produce arbitrarily large point sets. We evaluate our technique and compare it to the state-of-the-art sampling approaches.

This html bundle contains all the data that was collected while performing tests and comparisons between the LDBN sampler and various other samplers from the state of the art. You can click on any sampler to see all its associated data, discrepancy results, integration variance results, point distribution, behaviour relatively to aliasing (zoneplate tests), and spectral behaviour.
