Generating Surfaces of Variable Eccentricity Within a Ray Tracer
<p>Polynomial surfaces used in ray tracing have recently been improved upon allowing for three dimensional applications. Among these are surfaces that have a varying eccentricity. This paper will discuss a method for finding real roots of polynomials [allowing us to create these surfaces]. First, …

GPU ray tracing with CUDA
<p>"Ray Tracing is a rendering method that generates high quality images by simulating how light rays interact with objects in a virtual scene. The ray tracing technique can accurately portray advanced optical effects, such as reflections, refractions, and shadows, but at a greater computational …

Entwicklung einer simultanen refraktions- und reflexionsseismischen 3D-Laufzeittomographie mit Anwendung auf tiefenseismische TRANSALP-Weitwinkeldaten aus den Ostalpen
… accuracy of this method was adjusted for long ray paths and high resolution. Floating or discontinuous reflectors are modelled on separate grids by bi-cubic splines, and an appropriate reflection ray tracer was developed using the Approximate Ray Tracing/Pseudo Bending (ART/PB) method. Accuracy …

New proposals for the popularization of braid theory
… audience has been realized using the free ray-tracer POV-Ray. It is divided into four parts, each of which has a length of about 15 minutes. The content ranges from the introduction of basic concepts to deep results. The workshop activity is based on the action of braids on loops and aims …

Applications of Artificial Intelligence to Electromagnetism and Indoor Wireless Networks
… radio propagation modelling tool, named EM DeepRay, is developed by coupling a high-performance ray-tracer with a convolutional encoder-decoder. Then, the computational efficiency and robustness of EM DeepRay are exploited to develop an AI-assisted indoor wireless network planning framework, and …

Sampling Methods in Ray-Based Global Illumination
… The most versatile of these are based on ray tracing (following ray paths through a scene), and numerical integration using random or quasi-random sampling. While ray tracing and sampling methods in global illumination have progressed much in the last two decades, the goal of fast and …

Design of an HF transmit antenna for bistatic ionospheric soundings in Antarctica
… ICEPAC and the online Virginia Tech SuperDARN ray tracer ignore the presence of the extraordinary wave mode, the significance of which was discussed. The non-deviative radiowave absorption in the D and lower E layers of the ionosphere is one of the most notable contributors to total …
