Interactive global illumination on the CPU [PDF]

Computing realistic physically-based global illumination in real-time remains one of the major goals in the fields of rendering and visualisation; one that has not yet been achieved due to its inherent computational complexity.

An updated definition of global health

The most cited definition of global health, published in The Lancet in 2009, defines global health as "an area for study, research, and practice that places a priority on improving health and achieving equity in health for all people worldwide".

Underground low-light self-supervised image enhancement method based on structure and texture perception

Meitan xuebao
Due to the complex spatial environment and uneven artificial lighting underground, images captured by underground visual equipment often suffer from insufficient overall or partial lighting and poor visibility of image content. Existing image enhancement

Global illumination test scenes [PDF]

, 2000
journal articleThe global illumination community has discussed having a database of scenes that could be used to compare and validate different global illumination algorithms. We present a set of test scenes for global illumination algorithms and propose

Pressure‐Assisted Dimensional Transformation of 2D Hydrogenated Borophene into 0D Boron Quantum Dots

Advanced Functional Materials, EarlyView.
Hydrogenated borophene (HB) is transformed into distinct boron nanostructures through a solvent‐free thermal process. Under flowing nitrogen, hydrogen escape promotes reconstruction into B2O3 nanoplatelets, whereas hydrogen‐induced pressure under sealed conditions facilitates fragmentation into boron quantum dots.

Estimation of Local Illumination Consistency Based on Improved Vision Transformer [PDF]

Jisuanji gongcheng
Illumination consistency is a key factor in achieving the organic fusion of virtual and real elements in Augmented Reality (AR) systems. Owing to the constraints of capture perspectives and the complexity of scene illumination, developers often overlook ...

Anisotropic Phonon Dynamics and Directional Transport in Actinide Van der Waals Semiconductor Uranium Triselenide

Advanced Functional Materials, EarlyView.
USe3 is introduced as an actinide van der Waals semiconductor that mirrors the quasi‐one‐dimensional physics of transition‐metal trichalcogenides. Polarization‐resolved Raman spectroscopy on exfoliated flakes maps strong in‐plane phonon anisotropy and strain‐tunable mode shifts.

There-reality : selective rendering in high fidelity virtual environments [PDF]

, 2007
There-reality environments are those virtual environments which evoke the same perceptual response from a viewer as if they were actually present, or there, in the real scene being depicted.
