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 ...
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 ...
Dynamic Scheduling for Large-Scale Distributed-Memory Ray Tracing
(The Eurographics Association, 2012)
Ray tracing is an attractive technique for visualizing scientific data because it can produce high quality images that faithfully represent physically-based phenomena. Its embarrassingly parallel reputation makes it a ...
A Framework for Fast Initial Exploration of PC-MRI Cardiac Flow
(The Eurographics Association, 2016)
Cardiac flow is still not fully understood, and is currently an active research topic. Using phase-contrast magnetic resonance imaging (PC-MRI) blood flow can be measured. For the inspection of such flow, researchers often ...
Grid-Free Out-Of-Core Voxelization to Sparse Voxel Octrees on GPU
(ACM Siggraph, 2015)
In this paper, we present the first grid-free, out-of-core GPU voxelization method. Our method combines efficient parallel triangle voxelization on GPU with out-of-core technologies in order to allow the processing of ...
Temporal Interpolation of 4D PC-MRI Blood-flow Measurements Using Bidirectional Physics-based Fluid Simulation
(The Eurographics Association, 2016)
Magnetic Resonance Imaging (MRI) enables volumetric and time-varying measurements of blood-flow data. Such data have shown potential to improve diagnosis and risk assessment of various cardiovascular diseases. Hereby, a ...
Sline: Seamless Line Illustration for Interactive Biomedical Visualization
(The Eurographics Association, 2016)
In medical visualization of surface information, problems often arise when visualizing several overlapping structures simultaneously. There is a trade-off between visualizing multiple structures in a detailed way and ...
Unfolding and Interactive Exploration of Protein Tunnels and their Dynamics
(The Eurographics Association, 2016)
The presence of tunnels in protein structures substantially influences their reactivity with other molecules. Therefore, studying their properties and changes over time has been in the scope of biochemists for decades. In ...
Efficient Ray Tracing of Subdivision Surfaces using Tessellation Caching
(ACM Siggraph, 2015)
A common way to ray trace subdivision surfaces is by constructing and traversing spatial hierarchies on top of tessellated input primitives. Unfortunately, tessellating surfaces requires a substantial amount of memory ...
Bounding Volume Hierarchy Optimization through Agglomerative Treelet Restructuring
(ACM Siggraph, 2015)
In this paper, we present a new method for building high-quality bounding volume hierarchies (BVHs) on manycore systems. Our method is an extension of the current state-of-the-art on GPU BVH construction, Treelet Restructuring ...
