GPU Ray Tracing using Irregular Grids
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
We present a spatial index structure to accelerate ray tracing on GPUs. It is a flat, non-hierarchical spatial subdivision of the scene into axis aligned cells of varying size. In order to construct it, we first nest an ...
Foveated Real-Time Ray Tracing for Head-Mounted Displays
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Head-mounted displays with dense pixel arrays used for virtual reality applications require high frame rates and low latency rendering. This forms a challenging use case for any rendering approach. In addition to its ability ...
RTSG: Ray Tracing for X3D via a Flexible Rendering Framework
(The Eurographics Association, 2009)
VRML and X3D are the most widely adopted standards for interactive 3D content interchange. However, they are both designed around the common restricted functionality available in hardware graphics processors. Thus, most ...
Extending X3D for Distributed Multimedia Processing and Control
(The Eurographics Association, 2009)
Web-based applications of interactive 3D computer graphics are showing a tendency to get more interconnected and visually complex. Virtual communities like Second Life demand realism not only in terms of realistic rendering, ...
