End-to-End Data Reduction and Hardware Accelerated Rendering Techniques for Visualizing Time-Varying Non-uniform Grid Volume Data
(The Eurographics Association, 2005)
We present a systematic approach for direct volume rendering terascale-sized data that are time-varying, and possibly non-uniformly sampled, using only a single commodity graphics PC. Our method employs a data reduction ...
Fast Volumetric Data Exploration with Importance-Based Accumulated Transparency Modulation
(The Eurographics Association, 2010)
Direct volume rendering techniques have been successfully applied to visualizing volumetric datasets across many application domains. Due to the sensitivity of transfer functions and the complexity of fine-tuning transfer ...
Volume Graphics Modeling of Ice Thawing
(The Eurographics Association, 2001)
Image synthesis of natural phenomena is one of the fundamental research areas in volume graphics. Since the pursuit of photoreality requires physically-based computation at the cost of interactivity, much more attention ...
Correction of Voxelization Artifacts by Revoxelization
(The Eurographics Association, 2001)
Earlier proposed antialiasing techniques for voxelization of geometric objects in some cases do not result in completely alias-free data and image renditions. This is often the case for some implicit solids and CSG trees. ...
Efficient Space Leaping for Ray casting Architectures
(The Eurographics Association, 2001)
One of the most severe problems for ray casting architectures is the waste of computation cycles and I/O bandwidth, due to redundant sampling of empty space. While several techniques exist for software implementations to ...
GPU-assisted Multi-field Video Volume Visualization
(The Eurographics Association, 2006)
GPU-assisted multi-field rendering provides a means of generating effective video volume visualization that can convey both the objects in a spatiotemporal domain as well as the motion status of these objects. In this ...
3D Reconstruction of Emission and Absorption in Planetary Nebulae
(The Eurographics Association, 2007)
This paper addresses the problem of reconstructing the 3D structure of planetary nebulae from 2D observations. Assuming axial symmetry, our method jointly reconstructs the distribution of dust and ionized gas in the nebulae ...
Advanced Light Material Interaction for Direct Volume Rendering
(The Eurographics Association, 2010)
In this paper we present a heuristic approach for simulating advanced light material interactions in the context of interactive volume rendering. In contrast to previous work, we are able to incorporate complex material ...
Interactive Global Light Propagation in Direct Volume Rendering using Local Piecewise Integration
(The Eurographics Association, 2008)
A novel technique for efficient computation of global light propagation in interactive DVR is presented in this paper. The approach is based on a combination of local shadows from the vicinity of each voxel with global ...
Efficient Ambient and Emissive Tissue Illumination using Local Occlusion in Multiresolution Volume Rendering
(The Eurographics Association, 2007)
This paper introduces a novel technique to compute illumination for Direct Volume Rendering. By adding shadow effects to volume rendered images, the perception of shapes and tissue properties can be significantly improved ...
