Fast Collision Culling in Large-Scale Environments Using GPU Mapping Function
(The Eurographics Association, 2012)This paper presents a novel and efficient GPU-based parallel algorithm to cull non-colliding object pairs in very large-scale dynamic simulations. It allows to cull objects in less than 25ms with more than 100K objects. ... -
GLuRay: Enhanced Ray Tracing in Existing Scientific Visualization Applications using OpenGL Interception
(The Eurographics Association, 2012)Ray tracing in scientific visualization allows for substantial gains in performance and rendering quality with large scale polygonal datasets compared to brute-force rasterization, however implementing new rendering ar- ... -
HyperFlow: A Heterogeneous Dataflow Architecture
(The Eurographics Association, 2012)We propose a dataflow architecture, called HyperFlow, that offers a supporting infrastructure that creates an abstraction layer over computation resources and naturally exposes heterogeneous computation to dataflow processing. ... -
Light Propagation Maps on Parallel Graphics Architectures
(The Eurographics Association, 2012)Light going through a participating medium like smoke can be scattered or absorbed by every point in the medium. To accurately render such a medium we must compute the radiance resulting at every point inside the medium ... -
Load-Balanced Multi-GPU Ambient Occlusion for Direct Volume Rendering
(The Eurographics Association, 2012)Ambient occlusion techniques were introduced to improve data comprehension by bringing soft fading shadows to the visualization of 3D datasets. They consist in attenuating light by considering the occlusion resulting from ... -
Multi-GPU Image-based Visual Hull Rendering
(The Eurographics Association, 2012)Many virtual mirror and telepresence applications require novel viewpoint synthesis with little latency to user motion. Image-based visual hull (IBVH) rendering is capable of rendering arbitrary views from segmented images ... -
Parallel Rendering on Hybrid Multi-GPU Clusters
(The Eurographics Association, 2012)Achieving efficient scalable parallel rendering for interactive visualization applications on medium-sized graphics clusters remains a challenging problem. Framerates of up to 60hz require a carefully designed and fine-tuned ... -
PISTON: A Portable Cross-Platform Framework for Data-Parallel Visualization Operators
(The Eurographics Association, 2012)Due to the wide variety of current and next-generation supercomputing architectures, the development of highperformance parallel visualization and analysis operators frequently requires re-writing the underlying algorithms ... -
Polygonization of Implicit Surfaces on Multi-Core Architectures with SIMD Instructions
(The Eurographics Association, 2012)In this research we tackle the problem of rendering complex models which are created using implicit primitives, blending operators, affine transformations and constructive solid geometry in a design environment that organizes ... -
Shift-Based Parallel Image Compositing on InfiniBand TM Fat-Trees
(The Eurographics Association, 2012)Parallel image compositing has been widely studied over the past 20 years, as this is one, if not the most, crucial element in the implementation of a scalable parallel rendering system. Many algorithms have been proposed ... -
A Study of Ray Tracing Large-scale Scientific Data in Two Widely Used Parallel Visualization Applications
(The Eurographics Association, 2012)Large-scale analysis and visualization is becoming increasingly important as supercomputers and their simulations produce larger and larger data. These large data sizes are pushing the limits of traditional rendering ... -
Time-constrained Animation Rendering on Desktop Grids
(The Eurographics Association, 2012)The computationally intensive nature of high-fidelity rendering has led to a dependence on parallel infrastructures for generating animations. However, such an infrastructure is expensive thereby restricting easy access ...
