Spherical ray-tracing
… naturally fit into spherical coordinates. When tracing rays through naturally spherical domains (for example, for visualization), converting to Cartesian coordinates introduces aberrations. Therefore, we seek an algorithm to natively cast rays through spherical coordinates, and without …

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 …

Efficient Ray Tracing For Mobile Devices
… of quality.</p> <p>Other techniques, such as ray tracing, do not require such emulation to be implemented, as the aforementioned phenomena of light are inherently considered. In this work, we first design and implement a 3D renderer that uses ray tracing to generate high quality graphics for …

Microcellular radio channel prediction using ray tracing
… in outdoor microcellular radio channels using ray tracing. The basic method is to integrate site-specific environmental data with a geometrical optics model to trace the propagation of energy from the transmitter to the receiver. Software written in C++ is used to automatically trace rays that …

Stochastic acoustic ray tracing with dynamically orthogonal equations
… implementations of the Parabolic Equation, Ray Theory, and Level Sets methods for ocean acoustic computation. We investigate methods for evolving stochastic fields using direct Monte Carlo, Empirical Orthogonal Functions, and adaptive Dynamically Orthogonal (DO) differential equations. As we …

Ray tracing large distributed datasets using ray caches
… develop an in-situ visualization technique using ray tracing that employs ray caches to reduce communication overhead. Ray caches attempt to replace a communication operation with a less expensive cache search operation. A prototype implemented on Sharcnet shows ray caching can signi cantly …

Direct ray tracing for low energy electron microscopy
… particular, it investigates the use of a direct ray tracing method that employs the Cash-Karp 5th order Runge-Kutta technique in combination with a Fourier series fit to axial magnetic/electric field distributions. The direct ray tracing method was used successively to improve the design of …

Applications of ray tracing to a pseudophakic eye model
… This thesis investigates the application of ray tracing and general anterior corneal surface modeling, for the purpose of improving ophthalmic measurements and in particular, the estimation of IOL power. A new algorithm (based on a multi-step approach) for the recovery of the corneal height …

Optimized ray tracing for real time use without hardware accelerators
… begun including specialized cores to accelerate ray tracing, an alternative rendering solution to rasterization and a type of light transport simulation. Ray tracing is generally the more desirable choice due to its ability to present images with higher fidelity than rasterization, and due to …
