Ray Tracing for Undergraduates

چکیده
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 interactive rendering in coming years.

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 کاملAn Efficient Algorithm for General 3D-Seismic Body Waves (SSP and VSP Applications)
Abstract The ray series method may be generalized using a ray centered coordinate system for general 3D-heterogeneous media. This method is useful for Amplitude Versus Offset (AVO) seismic modeling, seismic analysis, interpretational purposes, and comparison with seismic field observations.For each central ray (constant ray parameter), the kinematic (the eikonal) and dynamic ray tracing system ...
متن کاملVelocity Modeling in a Vertical Transversely Isotropic Medium Using Zelt Method
In the present paper, the Zelt algorithm has been extended for ray tracing through an anisotropic model. In anisotropic media, the direction of the propagated energy generally differs from that of the plane-wave propagation. This makes velocity values to be varied in different directions. Therefore, velocity modeling in such media is completely different from that in an isotropic media. The vel...
متن کاملScene Graph Creation And Management For Undergraduates
This paper describes the context and results of a student project related to scene graphs spanning several assignments in an undergraduate computer graphics course. The project progressively built an application that created a list of objects from an XML specification, modified it into a scene graph, implemented part-by-part animation and added point lights and textures. Students were encourage...
متن کاملA Modular Infrastructure for Multi-Kernel Ray Traversals
Ray tracing on high performance computing hardware is a popular and active field of research. Our interactive ray tracing framework (http://www.cgv.tugraz.at/mrt) targets at modern massively parallel architectures and features different variants of ray tracing (Whitted-style, path tracing, ...) and applications. The modular system design is based on a wavefront tracing approach and ray loads wi...
