Latency aware foveated rendering in unreal engine 4 [PDF]

Proceedings of the 12th European Conference on Visual Media Production, 2015
We contribute a foveated rendering implementation in Unreal Engine 4 (UE4) and a straight-forward metric to allow calculation of rendered foveal region sizes to compensate for overall system latency and maintain perceptual losslessness. Our system demonstrates appreciable computational gains in large resolution real-time rendering scenarios.

3D As‐Built Environments in Extended Reality Applications: A Systematic Review

The Photogrammetric Record, Volume 41, Issue 194, April/June 2026.
This systematic review identifies BIM and game engines as the primary tools for integrating 3D as‐built environments into XR. While multi‐sensor fusion and multimodal interaction enhance immersion, persistent challenges like manual modeling and bandwidth limitations continue to hinder full ecosystem maturation.

Misinterpreting Electrophysiology in Human Cognitive Neuroscience

Psychophysiology, Volume 63, Issue 4, April 2026.
ABSTRACT An axiomatic view in contemporary neuroscience is that EEG components such as event‐related brain potentials (ERPs) and oscillations are directly interpretable as manifestations of biological processes that support sensory, motor, and cognitive constructs of interest.

Adaptive Foveated Rendering and Offloading in an Edge-Assisted Virtual Reality System

IEEE Access
Foveated rendering (FR)—in which the central foveal layer (the area around the eye gaze) of a virtual reality (VR) image is rendered at the highest resolution and the peripheral layers are rendered at progressively lower resolutions—is an ...

Stereoscopic Brightness Roll‐Off in Augmented Reality

Journal of the Society for Information Display, Volume 34, Issue 3, Page 85-98, March 2026.
The increasing demand for power‐efficient immersive augmented reality (AR) displays has led to a growing need for effective power‐saving strategies. Here, the authors investigate for the first time the stereoscopic effectiveness of brightness roll‐off (BRO) for perceptually‐optimized power savings in AR.

Comparing Perceptual Visual Quality of Hybrid Neural and Ray Tracing in Foveated Rendering

Journal on Interactive Systems
Enabling Foveated Rendering for VR devices displays is fundamental when dealing with real-time ray tracing. Combining traditional methods with Neural based strategies, such as NeRFs and 3D Gaussian Splatting, may impact on leveraging performance even ...

Measuring the Luminance Contrast Sensitivity Function in Peripheral Vision

Color Research &Application, Volume 51, Issue 1, January/February 2026.
Luminance contrast detection thresholds of frequencies at eccentricities for a person. ABSTRACT We measured luminance contrast sensitivity functions (CSF) of four subjects by using Gabor stimuli up to 56°, 49°, 84°, and 63° in the nasal, superior, temporal, and inferior directions, respectively, of the left‐eye visual field.

An Electroencephalographic Investigation of the Impact of Eye Movements in a Memory Probe Task

Psychophysiology, Volume 63, Issue 1, January 2026.
ABSTRACT Lateral saccades represent a major source of noise and confounds, particularly for event‐related potentials (ERPs) that rely on hemispheric imbalances in neural activity elicited by lateralized stimuli during central fixation. These include lateralized ERPs such as the contralateral delay activity (CDA), which indexes visual working memory ...
