چکیده

With the shift from highly clocked, single thread processors to chips that have dozens or even hundreds of smaller processors, we are witnessing a fundamental change in the computing hardware we use. This paper describes an approach to use modern many-core-hardware to apply real time ray tracing to Virtual Reality environments. We show that current hardware can speed up real time ray tracing to interactive frame rates that make ray tracing interesting for the integration into existing industrial Virtual Reality systems.

Shell: Accelerating Ray Tracing on GPU

Ray tracing is a fundamental process in many areas including computer graphics and medical applications. Different hierarchical acceleration structures for ray tracing have been developed. Such ray tracing approaches executed on advanced many-core processors such as GPU, however, turns out to be memory bounded due to their frequent search operations in the hierarchical structures. This paper pr...

Realtime ray tracing and interactive global illumination

One of the most sought-for goals in computer graphics is to generate “realism in real time”, i.e. the generation of realistically looking images at realtime frame rates. Today, virtually all approaches towards realtime rendering use graphics hardware, which is based almost exclusively on triangle rasterization. Unfortunately, though this technology has seen tremendous progress over the last few...

Software Shadows For Ray Tracing Using Hardware Cameras

The goal of ray tracing is to create images that are as accurate to real life as possible. Unfortunately, attaining this goal typically requires an extremely large amount of processing time. In this paper I propose a method for creating accurate soft shadows using graphics hardware to accelerate the process.

A virtual memory architecture for real-time ray tracing hardware

Real-time ray tracing offers a number of interesting benefits over current rasterization techniques. However, a major drawback has been that ray tracing requires access to the entire scene data base. This is particularly problematic for hardware implementations that only have a limited amount of dedicated on-board memory. In this paper we propose a virtual memory architecture for ray tracing th...

An efficient parallel architecture for ray-tracing

Real time rendering of three-dimensional scenes in high photorealistic details is a hard task, such as in the ray tracing rendering algorithm. In general, the performance achieved by a sequential software-based implementation of ray tracing is far from satisfactory. However, parallel implementations of ray tracing have been enabling reasonable real time performance, as the algorithm is embarras...
