Comparison of Phase Space and Quasi-Monte Carlo Ray Tracing for the 3D Compound Parabolic Concentrator [PDF]

EPJ Web of Conferences
Phase space ray tracing is an alternative to (Quasi-)Monte Carlo ray tracing in 2D. We introduce a 3D phase space algorithm and apply it to the compound parabolic concentrator.

DART-RAY: a 3D ray-tracing radiative transfer code for calculating the propagation of light in dusty galaxies [PDF]

, 2014
We present DART-Ray, a new ray-tracing 3D dust radiative transfer (RT) code designed specifically to calculate radiation field energy density (RFED) distributions within dusty galaxy models with arbitrary geometries. In this paper, we introduce the basic

Application of ionospheric tomography for high frequency oblique incidence ray tracing

Annals of Geophysics, 2016
Recognizing the applicability of tomographic imaging in the ionosphere, the reconstruction method has been applied to generate more realistic low latitude ionospheric background based on the Ionex TEC data and also direct measurement TEC data over West ...

Public Release of RELXILL_NK: A Relativistic Reflection Model for Testing Einstein's Gravity [PDF]

, 2019
We present the public release version of relxill_nk, an X-ray reflection model for testing the Kerr hypothesis and general relativity. This model extends the relxill model that assumes the black hole spacetime is described by the Kerr metric.

A new hybrid geometrical optics and radiance based scattering model for ray tracing applications [PDF]

, 2005
This paper presents a new hybrid geometrical optics (GO) and radiance based rough surface scattering model for use in ray tracing propagation models. The reflectance model includes the effects of both specular and diffuse reflection.

And…Action! Setting the Scene for Accurate Visual CFD Comparisons Using Ray Tracing

Journal of Marine Science and Engineering, 2021
Increased graphical capabilities of contemporary computer hardware make ray tracing possible for a much wider range of applications. In science, and numerical fluid mechanics in particular, visual inspections still play a key role in both understanding ...

RAY TRACING RENDER MENGGUNAKAN FRAGMENT ANTI ALIASING

JUTI: Jurnal Ilmiah Teknologi Informasi, 2008
Rendering is generating surface and three-dimensional effects on an object displayed on a monitor screen. Ray tracing as a rendering method that traces ray for each image pixel has a drawback, that is, aliasing (jaggies effect). There are some methods

Transient optical simulation by coupling elastic multibody systems, finite elements, and ray tracing

Journal of the European Optical Society-Rapid Publications, 2023
Transient dynamical–thermoelastic–optical system simulation is an important expansion of classical ray tracing through rigid, resting lenses because the operating performance of high-precision optical systems can be influenced by dynamical excitations or

ROBAST: Development of a ROOT-Based Ray-Tracing Library for Cosmic-Ray Telescopes and its Applications in the Cherenkov Telescope Array

, 2015
We have developed a non-sequential ray-tracing simulation library, ROOT-based simulator for ray tracing (ROBAST), which is aimed to be widely used in optical simulations of cosmic-ray (CR) and gamma-ray telescopes.
