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

Fast ray tracing by ray classification [PDF]
ACM SIGGRAPH Computer Graphics, 1987 We describe a new approach to ray tracing which drastically reduces the number of ray-object and ray-bounds intersection calculations by means of 5-dimensional space subdivision. Collections of rays originating from a common 3D rectangular volume and directed through a 2D solid angle are represented as hypercubes in 5-space.

Tracing ray differentials [PDF]
Proceedings of the 26th annual conference on Computer graphics and interactive techniques - SIGGRAPH '99, 1999 Antialiasing of ray traced images is typically performed by supersampling the image plane. While this type of filtering works well for many algorithms, it is much more efficient to perform filtering locally on a surface for algorithms such as texture mapping.

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 ...

A Study on mm-Wave Propagation in and Around Buildings
IEEE Open Journal of Antennas and Propagation, 2023 mm-waves are envisaged as a key enabler for 5G and 6G wireless communications, thanks to the wide bandwidth and to the possibility of implementing large-scale antenna arrays and advanced transmission techniques, such as massive MIMO and beamforming, that

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

Vicinity ray tracing: an alternative to dynamic ray tracing [PDF]
Geophysical Journal International, 1990 SUMMARY A method for computing seismic wavefields in a high-frequency approximation is proposed based on the integration of the kinematic ray tracing equations and a new set of differential equations for the dynamic properties of the wavefront, which we call the vicinity ray tracing (VRT) equations.
