International Workshop on Volume Graphics

Monday, June 20 8:30 - 8:45  Opening  (Arie Kaufman, Honorary Chair) 8:45 - 9:45  Keynote:  Holly Rushmeier (Yale University) Modeling Volume Textures Since their introduction in seminal papers by Peachey and Perlin in 1985, volume textures have been a popular modeling tool. Not only  are they useful for creating complex and consistent textures, they are needed for rendering weathering effects on various materials such as  stone, as demonstrated by Dorsey et al. in 1999. While it is possible to generate volume textures purely procedurally, recent interest in 2D texture synthesis from example has spurred interest in synthesizing volumetric textures from physical examples. I  will present applications where volumes textures from samples are of  interest, some approaches to estimating them, and some early work on evaluating whether the synthesized volumes are correct. More information is available on the keynote page. 9:45 - 11:00  Paper Session 1:  Rendering of Time-Varying Data (session chair: Roger Crawfis) A Multiresolution Volume Rendering Framework for Large-Scale Time-Varying Data Visualization Chaoli  Wang, The Ohio State University Jinzhu  Gao, Oak Ridge National Laboratory Liya Li, The Ohio State University Han-Wei Shen, The Ohio State University Visualization of Time-Varying Volumetric Data using Differential Time-Histogram Table Hamid Younesy, Simon Fraser University Torsten  Möller, Simon Fraser University Hamish Carr, University College, Dublin A Hardware-Accelerated, Multiresolution Technique for Visualizing Time-Varying Volume Data Hiroshi  Akiba, University of California at Davis Kwan-Liu Ma, University of California at Davis John Clyne, National Center for Atmospheric Research 11:00 - 11:15  Coffee Break 11:15 - 12:30  Paper Session 2:  Medical Applications (session chair: Michael Meissner) An Evaluation of Using Real-time Volumetric Display of 3D Ultrasound Data Aaron Wang, Stanford University Girish  Narayan, Stanford University David Kao, NASA Ames Research Center David Liang, Stanford University Scaffolding-based Segmentation of Coronary Vascular Structures Dirk Bartz, University of Tübingen Sarang Lakare, Siemens Medical Solutions A Virtual Reality Toolkit for the Diagnosis and Monitoring of Myocardial Infarctions John Ryan, Trinity College Dublin Carol O'Sullivan, Trinity College Dublin Christopher Bell, Trinity College Dublin Niall Mulvihill, St James' Hospital, / Trinity College Dublin 12:30 - 1:30  Lunch Break 1:30 - 2:45  Paper Session 3:  Rendering with Physics (session chair: Amitabh Varshney) A Simplifed Model for Inhomogeneous Subsurface Scattering Richard Sharp, The Ohio State University Raghu Machiraju, The Ohio State University Accelerated, High-Quality Refraction Computations for Volume Graphics Shengying Li, Stony Brook University Klaus Mueller, Stony Brook University Volumetric Reconstruction, Compression and Rendering of Natural Phenomena from Multi-Video Data Lukas Ahrenberg, Max-Planck-Institut für Informatik Ivo Ihrke, Max-Planck-Institut für Informatik Markus Magnor, Max-Planck-Institut für Informatik 2:45 - 3:45  Posters: Short Oral Presentations, Followed by Poster Session with Coffee (session chair: Andreas Bærentzen) Adaptive and Scalable Load Balancing Scheme for Sort-Last Parallel Volume Rendering on GPU Clusters Won-Jong Lee, Yonsei University Vason P.

Sophisticated graphics was now accessible to a much larger audience and developer pool than before. A similar revolution is happening right now as mobile devices such as PDAs and cellular phones have their own standard 3D APIs, high-quality color displays, and even hardware acceleration is starting to become available. This talk will cover the graphics capabilities of modern mobile devices, their limitations, and graphics APIs designed for these devices. We will also discuss what is unique with mobile graphics compared to desktop graphics.
