Using raytraverse to render high accuracy images
Raytraverse is a python based software that helps to efficiently organize and guide the sampling of a lighting simulation within a scene. Radiance is embedded within Raytraverse to provide accurate and efficient solutions for each sampled ray. This talk wi ...
2023Content-Preserving Unpaired Translation from Simulated to Realistic Ultrasound Images
Interactive simulation of ultrasound imaging greatly facilitates sonography training. Although ray-tracing based methods have shown promising results, obtaining realistic images requires substantial modeling effort and manual parameter tuning. In addition, ...
Springer2021A Correlation-Based Electromagnetic Time Reversal Technique to Locate Indoor Transient Radiation Sources
Marcos Rubinstein, Zhaoyang Wang, Qi Li
To overcome the multipath interference in locating transient electromagnetic (EM) radiation sources in an indoor environment, we propose a criterion that calculates the correlation between back-propagated signals from observation points, to be used in EM t ...
2021Casting position effects on bond performance of reinforcement bars
Aurelio Muttoni, Miguel Fernández Ruiz, Francesco Rafael Alberto Moccia
The phenomena associated with the consolidation of fresh concrete (bleeding and plastic settlement) are commonly considered significant for the bond performance of reinforcement. However, rules to take care of such influence for design are not consistent a ...
ERNST & SOHN2021Better Patch Stitching for Parametric Surface Reconstruction
Pascal Fua, Mathieu Salzmann, Zhantao Deng, Jan Bednarík
Recently, parametric mappings have emerged as highly effective surface representations, yielding low reconstruction error. In particular, the latest works represent the target shape as an atlas of multiple mappings, which can closely encode object parts. A ...
IEEE2020Evaluation of the ray-casting analytical algorithm for pencil beam scanning proton therapy
For pencil beam scanned (PBS) proton therapy, analytical dose calculation engines are still typically used for the optimisation process, and often for the final evaluation of the plan. Recently however, the suitability of analytical calculations for planni ...
2019A method for voxel ray-casting of scenes on a whole screen
A method for screen-space voxel ray-casting of scenes on a whole screen. The method comprises providing a graphics card; rendering seamlessly any one of the following list of primitives containing at least polygons, voxels; using a GPU pipeline of the grap ...
2019Holographic Visualisation and Interaction of Fused CT, PET and MRI Volumetric Medical Imaging Data Using Dedicated Remote GPGPU Ray Casting
Patric Hagmann, Stéphane Gobron, Adrien Raphaël Depeursinge
Medical experts commonly use imaging including Computed Tomography (CT), Positron-Emission Tomography (PET) and Magnetic Resonance Imaging (MRI) for diagnosis or to plan a surgery. These scans give a highly detailed representation of the patient anatomy, b ...
SPRINGER INTERNATIONAL PUBLISHING AG2018Experimental demonstration of ray-rotation sheets
We have built microstructured sheets that rotate, on transmission, the direction of light rays by an arbitrary, but fixed, angle around the sheet normal. These ray-rotation sheets comprise two pairs of confocal lenticular arrays. In addition to rotating th ...
2018An embedded system for quasi real-time lighting computation based on sky monitoring
Jean-Louis Scartezzini, Jérôme Henri Kämpf, Yujie Wu
Lighting simulation plays a significant role in the architectural design and evaluation of performance parameters of buildings. The general method of assuming a virtual sky in lighting simulation may lead to mismatch with the real situation, which conventi ...
