Aerosol and non-aerosol drivers of regional trends in top-of-atmosphere albedo over 2002–2020

Environmental Research Letters
Climate change responds to, and in turn modifies, trends in the Earth’s top-of-atmosphere (TOA) albedo. These trends are caused in particular by anthropogenic aerosol-radiation and aerosol-cloud interactions, as well as by non-aerosol feedbacks involving

One‐more‐vertex Next‐Event Estimation with Hierarchical Geometry Sampling

Computer Graphics Forum, EarlyView.
Abstract Robust next‐event estimation (NEE) remains a challenge in scenes characterized by sparse or small‐scale geometry where indirect illumination is the primary transport mechanism. In these scenes, traditional path construction, which relies on local directional sampling, often fails to find intersections with the sparse geometry, and standard NEE

Volumetric Inverse Rendering via Neural Radiative Transfer

Computer Graphics Forum, EarlyView.
Abstract Volumetric inverse rendering seeks to recover the optical properties of participating media from images. Existing approaches either rely on differentiable stochastic light transport simulation, which require substantial algorithmic effort, or use simplified models that fail to capture global illumination.

Diurnal asymmetry of surface albedo in a semi‐arid grassland over the China's Loess Plateau

Atmospheric Science Letters
In current land surface models or satellite remote sensing retrievals, clear‐sky surface albedo (α) is usually assumed to be symmetrical and relies only on the solar elevation angle (SEA).

Variation in Glacier Albedo on the Tibetan Plateau between 2001 and 2022 Based on MODIS Data

Remote Sensing
Albedo is a primary driver of the glacier surface energy balance and consequent melting. As glacier albedo decreases, it further accelerates glacier melting.

Frequency‐Aware Spatial‐Angular Gaussians for Efficient Global Illumination Precomputation and Real‐Time Rendering

Computer Graphics Forum, EarlyView.
Abstract Precomputation and efficient approximate material models are well‐known approaches for achieving real‐time rendering with global illumination. Recent research in radiance fields and in particular 3D Gaussian Splatting has demonstrated the power of Gaussian primitives both to represent radiance and for fast optimization.

Beyond Spherical Harmonics: Rethinking Appearance Models for Radiance Reconstruction

Computer Graphics Forum, EarlyView.
Abstract View‐dependent appearance modeling remains a challenging problem in novel‐view synthesis and reconstruction. Accurately representing complex angular effects often requires substantial memory and computational resources. For new learning‐based methods, a common approach is to rely on Spherical Harmonics (SH).

ResEdit: Residual embeddings for precise generative image editing

Computer Graphics Forum, EarlyView.
Abstract Conditional diffusion image generators can be repurposed for editing through inversion, without the need for large‐scale paired fine‐tuning data. However, producing high‐quality, targeted edits while maintaining image identity and global consistency remains challenging, as weakly conditioned inversion often embeds conflicting image features ...
