Fast holographic generation technology depends on the swift creation of computer-generated holograms (CGHs). Currently, the fast generation method of computer-generated holograms based on ray tracing is still based on non-physical ray tracing methods ...

Application of ionospheric tomography for high frequency oblique incidence ray tracing
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 ...

Visual Importance-Biased Image Synthesis Animation [PDF]
Present ray tracing algorithms are computationally intensive, requiring hours of computing time for complex scenes. Our previous work has dealt with the development of an overall approach to the application of visual attention to progressive and adaptive

Improved mapping functions for atmospheric refraction correction in SLR [PDF]
[1] We present two new mapping functions (MFs) to model the elevation angle dependence of the atmospheric delay for satellite laser ranging (SLR) data analysis.

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

RAY TRACING RENDER MENGGUNAKAN FRAGMENT ANTI ALIASING
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

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

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

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