Ray-tracing and Interferometry in Schwarzschild Geometry
Here, we investigate the possible optical anisotropy of vacuum due to gravitational field. In doing this, we provide sufficient evidence from direct coordinate integration of the null-geodesic equations obtained from the Lagrangian method, as well as ray-tracing equations obtained from the Plebanski’s equivalent medium theory. All calculations are done for the Schwarzschild geometry, which resu...
متن کاملRay tracing of dynamic scenes
In the last decade ray tracing performance reached interactive frame rates for nontrivial scenes, which roused the desire to also ray trace dynamic scenes. Changing the geometry of a scene, however, invalidates the precomputed auxiliary data-structures needed to accelerate ray tracing. In this thesis we review and discuss several approaches to deal with the challenge of ray tracing dynamic scen...
متن کاملDynamic Acceleration Structures for Interactive Ray Tracing
Acceleration structures used for ray tracing have been designed and optimized for efficient traversal of static scenes. As it becomes feasible to do interactive ray tracing of moving objects, new requirements are posed upon the acceleration structures. Dynamic environments require rapid updates to the acceleration structures. In this paper we propose spatial subdivisions which allow insertion a...
متن کاملObscurances for ray-tracing
We present a powerful method to create realistic-looking pictures of scenes with objects that have diffuse and non-diffuse properties. The method recreates the obscurances technique, introduced some years ago, with a new approach based on ray-tracing. The first version of the obscurances technique was used only for diffuse environments. It is already working successfully in some widely known vi...
متن کاملRay Tracing for Undergraduates
The computer graphics research community has recently renewed its interest in ray tracing, an image synthesis algorithm that simulates the interaction of light with an environment to generate highly realistic images (Figure 1). Recent hardware trends and algorithmic developments make the technique competitive with raster-based algorithms, and some suggest that ray tracing will begin to dominate...
