Advanced Site-Specific Propagation Prediction Techniques
… discussed as well as an overview of the numerous ray tracing techniques that exist in the literature. Finally, a new 3D ray launching method is presented which improves upon many of the existing ray tracing algorithms. The thesis demonstrates how this algorithm is capable of recovering very …

Long-Distance Flux Mapping Using Low-Cost Collimated Pyranometers
… Heliostat Target (LRHT) is a vertical array of collimated pyranometers deployed to a test site via flat-bed trailer and quickly erected on an aluminum truss tower. Once the sensors have been aimed at the heliostat, the heliostat beam is swept azimuthally across the array whereupon the …

Novel Site-Specific Techniques for Predicting Radio Wave Propagation
… to site-specific propagation prediction using ray tracing techniques. Propagation prediction based on ray tracing techniques requires that all the different physical objects, which affect the propagation of radio waves, be modeled. The first part of the thesis concentrates on modeling the …

Immersive real-time multi-user interaction with computer simulated pedestrians during emergencies
… visualisation has been limited to expensive ray tracing algorithms as a post-processing tool, not allowing real-time virtual environments to benefit from accurate fire smoke visibility representation.

Simulation of optical impacts of gravity-induced deformations of concentrating solar collectors
… the solar collector after gravity deformation. Ray tracing is used to fully analyze the optical performance of collectors. Together the deformations and beam characterization lead to a useful, cost-effective process to analyze solar collectors. The results of the study show that the simulations …

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 …
