Accelerating Volume Raycasting using Occlusion Frustums
(The Eurographics Association, 2008)
GPU-based volume raycasting allows to produce high quality renderings on current graphics hardware. The use of such raycasters is on the rise due to their inherent flexibility as well as the advances in hardware performance ...
Smooth Mixed-Resolution GPU Volume Rendering
(The Eurographics Association, 2008)
We propose a mixed-resolution volume ray-casting approach that enables more flexibility in the choice of downsampling positions and filter kernels, allows freely mixing volume bricks of different resolutions during rendering, ...
Stereo Pseudo 3D Rendering for Web-based Display of Scientific Volumetric Data
(The Eurographics Association, 2008)
Advancement in high-throughput microscopy technology such as the Knife-Edge Scanning Microscopy (KESM) is enabling the production of massive amounts of high-resolution volumetric data of biological microstructures. To fully ...
Stroke-Based Transfer Function Design
(The Eurographics Association, 2008)
In this paper we propose a user interface for the design of 1D transfer functions. The user can select a feature of interest by drawing one or more strokes directly onto the volume rendering near its silhouette. Based on ...
On Accuracy of Marching Isosurfacing Methods
(The Eurographics Association, 2008)
Representational accuracy of the isosurface meshes produced by well-known marching isosurfacing methods is considered. Accuracy is determined versus the isosurface given by trilinear interpolation and quantified using a ...
Memory Efficient GPU-Based Ray Casting for Unstructured Volume Rendering
(The Eurographics Association, 2008)
Volume ray casting algorithms benefit greatly with recent increase of GPU capabilities and power. In this paper, we present a novel memory efficient ray casting algorithm for unstructured grids completely implemented on ...
Obscurance-based Volume Rendering Framework
(The Eurographics Association, 2008)
Obscurances, from which ambient occlusion is a particular case, is a technology that produces natural-looking lighting effects in a faster way than global illumination. Its application in volume visualization is of special ...
GPU-based Particle Systems for Illustrative Volume Rendering
(The Eurographics Association, 2008)
Illustrative techniques are generally applied to produce stylized renderings. Various illustrative styles have been applied to volumetric data sets, producing clearer images and effectively conveying visual information. ...
Isosurface Ambient Occlusion and Soft Shadows with Filterable Occlusion Maps
(The Eurographics Association, 2008)
Volumetric data sets are often examined by displaying isosurfaces, surfaces where the data or function takes on a given value. We propose a new method for rendering isosurfaces at interactive rates while supporting dynamic ...
Parallel Construction of k-Nearest Neighbor Graphs for Point Clouds
(The Eurographics Association, 2008)
We present a parallel algorithm for k-nearest neighbor graph construction that uses Morton ordering. Experiments show that our approach has the following advantages over existing methods: (1) Faster construction of k-nearest ...
