Quantized Robust Event-Triggered MPC for Linear Discrete-Time Systems
IEEE AccessThis paper presents a Quantized Event-Triggered Model Predictive Control (QET-MPC) framework for linear discrete-time systems with bounded disturbances, introducing a unified treatment of event-triggering and dynamic quantization within a dual-mode MPC ...

Microsecond X‐ray reflectometry
Journal of Applied Crystallography, EarlyView.X‐ray reflectometry is accelerated to 213 µs net exposure time using galvanometer scanning, which enables unprecedented temporal resolution for studying dynamic thin‐film processes.We accelerate synchrotron X‐ray reflectometry (XRR) by more than an order of magnitude and demonstrate the acquisition of full reflectivity curves within 213 µs over a qz ...

A Real‐Time Multi‐Scale Neural Representation for Complex Surface Reflectance
Computer Graphics Forum, EarlyView.Abstract Recent machine learning methods have significantly advanced the state of the art in the classic problem of representing surface appearance over angle, space, and scale. The models tend, however, to be relatively heavy compared to traditional fixed‐function representations, making real‐time application challenging.

TABI: Tight and Balanced Interactive Atlas Packing
Computer Graphics Forum, EarlyView.Abstract Atlas packing is a key step in many computer graphics applications. Packing algorithms seek to arrange a set of charts within a fixed‐size atlas with as little downscaling as possible. Many packing applications such as content creation tools, dynamic atlas generation for video games, and texture space shading require on‐the‐fly interactive ...

Stochastic Pairwise MIS for Unbiased Large‐Kernel Reuse in Real‐Time
Computer Graphics Forum, EarlyView.Abstract Spatiotemporal resampling methods such as ReSTIR decrease noise in Monte Carlo rendering of dynamic content by reusing paths across frames and pixels. Standard ReSTIR reuses spatially from a small number of randomly selected neighbors. This reuse suffers when few neighbors contain contributing samples, reducing quality toward that of the ...

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.

Evaluating Encodings for Bivariate Edges in Adjacency Matrices
Computer Graphics Forum, EarlyView.Abstract We present the first empirical evaluation of techniques for encoding distributions of quantitative edge values within adjacency matrices. In many real‐world networks, edges represent not a single value but a set of measurements. While adjacency matrices preserve structural clarity, their compact cells limit the simultaneous display of multiple

Survey on Visualization of Information Diffusion over Networks
Computer Graphics Forum, EarlyView.Abstract Information Diffusion (ID) describes how a value (e.g., a pathogen, a rumor, a packet) spreads through an underlying “medium” network of elements (e.g., a social or computer network). Understanding the information diffusion process is essential to predicting trends, controlling misinformation, and enhancing decision‐making as well as ...
