NAADF: Globally Illuminated Voxel Worlds Accelerated with Nested Axis‐Aligned Distance Fields

open access: yesComputer Graphics Forum, EarlyView.
Abstract Achieving realistic rendering of 3D scenes in real time using path tracing is challenging due to the high sample count required, with ray tracing as the bottleneck. Focusing on voxels as a geometry representation offers significant opportunities for optimizations, especially for tracing the rays, but also for computing the samples.

Geometry‐Aware Alignment and Comparison of Hierarchical Morse Complexes with Applications

open access: yesComputer Graphics Forum, EarlyView.
Abstract Scalar fields derived from 3D X‐ray CT scans of samples undergoing ex situ processes, such as thermal aging, chemical etching, or mechanical stress, pose unique challenges for characterizing similarities and differences across acquisitions. Typically, a sample A (source) is imaged, removed, and subjected to experimental conditions that alter ...

The Great Dividing Range as a driver of genetic divergence in a low‐dispersing dragonfly

open access: yesEcological Entomology, EarlyView.
Population genomic analyses revealed low genetic differentiation and no discrete population structure across the Great Dividing Range, indicating widespread gene flow in Synthemis eustalacta. Genetic divergence was associated with environmental gradients, elevation and landscape resistance rather than geographic distance, supporting isolation by ...

The many prices of war and occupation: Black markets and the cost‐of‐living index in France, 1938–1949

open access: yesThe Economic History Review, EarlyView.
Abstract When studying French prices between 1938 and 1949, economists and historians face a paradox: whilst a vast black market shaped daily life, official indices recorded only state‐controlled prices. This article addresses the issue by introducing a new consumer price index that incorporates both official and black market prices.
