Interactive Headlight Simulation - A Case Study of Interactive Distributed Ray Tracing -
(The Eurographics Association, 2002)
Todays rasterization graphics hardware provides impressive speed and features making it the standard tool for interactively visualising virtual prototypes early in the industrial design process. However, due to inherent ...
Interactive Global Illumination in Complex and Highly Occluded Environments
(The Eurographics Association, 2003)
Global illumination algorithms have traditionally been very time consuming and were only suitable for off-line computations. Recent research in realtime ray tracing has improved global illumination performance to allow for ...
Interactive Global Illumination using Fast Ray Tracing
(The Eurographics Association, 2002)
Rasterization hardware provides interactive frame rates for rendering dynamic scenes, but lacks the ability of ray tracing required for efficient global illumination simulation. Existing ray tracing based methods yield ...
Improved Two-Level BVHs Using Partial Re-Braiding
(ACM, 2017)
We propose a novel approach for improving the quality of two-level BVHs (i.e., a two-level data structure that uses a top-level BVH built over second-level object BVHs). After building an individual, high-quality BVH for ...
Efficient Ray Traced Soft Shadows using Multi-Frusta Tracing
(The Eurographics Association, 2009)
Ray tracing has long been considered to be superior to rasterization because its ability to trace arbitrary rays, allowing it to simulate virtually any physical light transport effect by just tracing rays. Yet, to look ...
Interactive Distributed Ray Tracing of Highly Complex Models
(The Eurographics Association, 2001)
Many disciplines must handle the creation, visualization, and manipulation of huge and complex 3D environments. Examples include large structural and mechanical engineering projects dealing with entire cars, ships, buildings, ...
Robust Iterative Find-Next-Hit Ray Traversal
(The Eurographics Association, 2018)
We present two different methods for improving the performance and robustness of ray tracing algorithms that require iterating through multiple successive intersections along the same ray. Our methods do so without ever ...
Exploiting Local Orientation Similarity for Efficient Ray Traversal of Hair and Fur
(The Eurographics Association, 2014)
Hair and fur typically consist of a large number of thin, curved, and densely packed strands which are difficult to ray trace efficiently. A tight fitting spatial data structure, such as a bounding volume hierarchy (BVH), ...
Local Shading Coherence Extraction for SIMD-Efficient Path Tracing on CPUs
(The Eurographics Association, 2016)
Accelerating ray traversal on data-parallel hardware architectures has received widespread attention over the last few years, but much less research has focused on efficient shading for ray tracing. This is unfortunate ...
Compressed-Leaf Bounding Volume Hierarchies
(ACM, 2018)
We propose and evaluate what we call Compressed-Leaf Bounding Volume Hierarchies (CLBVH), which strike a balance between compressed and non-compressed BVH layouts. Our CLBVH layout introduces dedicated compressed multi-leaf ...
