High‐Gloss SVBRDF Capture Using Bounce Light

Computer Graphics Forum, EarlyView.
Abstract Reflectance capture aims at the visual reproduction of an object under varying illumination. Past works differ substantially in their experimental overhead, from single‐ or few‐image approaches, that employ significant (often learned) priors at the expense of biased reconstructions, to more accurate approaches that tend to be time‐consuming ...

Layer3D: A 3D Layered Representation for Multiview Vector Graphics

Computer Graphics Forum, EarlyView.
Abstract We present Layer3D, a novel 3D neural representation that models objects as collections of decomposable neural implicit primitives. These primitives enable the generation of layered images with consistent correspondences across viewpoints, establishing a flexible framework for multiview vector graphics decomposition.

The sub-seasonal and interannual spatio-temporal variability of bare-ice albedo of Abramov Glacier, Kyrgyzstan

Journal of Glaciology
As snowlines retreat, the bare ice of Central Asian glaciers is increasingly exposed to short-wave radiation and high temperatures. The importance of bare-ice albedo for glacier melt rates is thus rising. Little is known about the variability of bare-ice

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

Computer 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.

Parametric Sensitivity of Hemispheric Albedo Symmetry Weakly Constrains Shortwave Cloud Radiative Feedbacks in the Community Atmosphere Model Version 6

Geophysical Research Letters
Earth's albedo is symmetric between the northern and southern hemispheres (NH and SH, respectively) because SH clouds compensate for higher NH clear‐sky albedo, a feature that climate models have difficulty capturing.

Rational determination of real‐life UV exposure across latitudes: An extended Diffey‐based model integrating behavioural factors

International Journal of Cosmetic Science, EarlyView.
This study models real‐life UVB and UVA exposure across latitudes and seasons using an extended Diffey framework with behavioural corrections. Findings reveal predictable dose patterns and support pragmatic SPF and UVA‐PF caps, offering a quantitative basis for realistic photoprotection and regulatory discussion.

Visible, near‐, and thermal infrared spectra of asteroid Bennu samples: Relationship to and implications for remote sensing of carbonaceous asteroids

Meteoritics &Planetary Science, EarlyView.
Abstract Remote spectroscopy is used to characterize the mineralogy and infer the history of planetary bodies. Carbonaceous asteroids, such as B‐type (101955) Bennu, represent the earliest stages of planet formation. B types have a blue (negative) spectral slope and comprise <5% of asteroids.

Advanced aqueous alteration in primitive meteorites: Micro‐ to nanoscale studies of CR1 iron sulfides

Meteoritics &Planetary Science, EarlyView.
Abstract This study documents micro‐ to nanoscale observations of primary nebular and secondary parent body iron sulfides in the CR1 GRO 95577. Despite the extensive alteration of the bulk sample, some primary sulfides managed to avoid alteration, having originally formed in the solar nebula during chondrule formation by either fission‐sulfidization or

LifeMet: Report on the 2024–2025 meteorite recovery expedition in Dronning Maud Land, Antarctica for the study of microbe–meteorite interactions

Meteoritics &Planetary Science, EarlyView.
Abstract Since the discovery of nine meteorites near the Yamato mountains in 1969, Antarctica has been recognized as a superb location for meteorite recovery. While Antarctic recovery expeditions prioritize meteorite preservation for mineralogical and planetary studies, meteorites are not typically collected for biological applications.

The role of composition in the spectral evolution of carbonaceous asteroids as informed by Bennu sample return

Meteoritics &Planetary Science, EarlyView.
Abstract Near‐Earth rubble‐pile asteroids Bennu and Ryugu are part of the carbonaceous taxonomic complex (C‐complex), and samples returned from both bodies resemble the most aqueously altered carbonaceous chondrites. However, telescopic and spacecraft visible–near infrared (VIS–NIR) reflectance spectra of Ryugu exhibit a red (positive) spectral slope ...
