International Workshop on Volume Graphics

24 - 25 March 1999

Swansea, United Kingdom

CALL FOR PAPERS

Objectives

The advances in volume visualisation over the past decades, coupled with the rapid increase in computer power, suggest that volume visualisation may be developed into volume graphics, as a general purpose graphics technology. In order to explore further the potential of volume-based techniques, especially beyond the scope of volume visualisation, it is necessary to bring together researchers and applications developers from both the academic and industry sectors who are working, or wish to work, on volume-based graphics techniques. The objective of this workshop is therefore to provide the international computer graphics community with a platform to: 
  • assess and review the developments of techniques for volume-based modelling, rendering, manipulation and applications. 
  • develop a scientific framework for the research and development in volume graphics as an emerging sub-field of computer graphics, and compile a clear picture of existing knowledge and topics for further investigation. 
  • challenge researchers in areas of volume visualisation and other volume-based graphics work to develop their work further in order to impact on the mainstream computer graphics, and to explore a wider range of applications.

Workshop Themes

The programme committee of the workshop is seeking research papers and proposals for panel discussions concerning all aspects of volume graphics. Contributions that review the existing techniques in certain aspects and provide forward looking into the future development are also welcome. Topics of interest for the workshop include (but are not limited to): 
 
Volume Based Modelling Volume Rendering
Complex and multi-volume scenes Volume rendering hardware
Image-based 3D modelling Direct volume rendering
Frequency-domain modelling Voxel-based radiosity
Physically based modelling Illumination
Motion and Deformation Reflection and refraction
Mathematical Foundations Shadowing
Standards for volume-based representations Texture mapping
Non-photorealistic rendering
Parallel and distributed rendering
Data Acquisition and Manipulation Applications and Case Studies
Digitisation Medical imaging and surgical planning
Voxelisation and surface reconsu Forensic science
Segmentation and feature extraction Scientific computation
Compression Entertainment industry
Distortion and morphing Internet-based applications
Interaction and GUI design Collaborative visualisation

Keynote and Invited Speeches

Arie Kaufman (USA): State of the art in volume graphics 
Roni Yagel (Israel): Volume rendering: victories, defeats, and future challenges 
Wolfgang Strasser (Germany): Survey on high performance volume graphics hardware 
Greg Nielson (USA): Volume-based modelling techniques 
Ken Brodlie (UK): Volume Graphics and the Internet 

Questions 
1. Is storage requirement for volume representations really more expensive than polygonal representations? What would be the merits and demerits of having volumetric datasets, instead of triangle meshes, as the primitive (or primary?) graphics representation? 
2. How should reflection, refraction and shadow be specified and 
rendered in volume graphics, especially, when it involves amorphous volumetric datasets? 
3. Since a raster image is a 2D volume dataset, an animation sequence is a volume dataset, and some image-based modelling methods employs higher-dimensional volume datasets, what are the mathematical concepts which may unify various volume-based modelling and rendering techniques, and assist in the development of homogeneous graphics hardware and Application Programming Interfaces (APIs)? 
4. Is voxel-based radiosity computationally feasible? Do volumetric datasets offer any advantages for the calculation of global illumination? 
5. Can "the Visible Human" walk? - Motion capture and computational physics can naturally operate on connected solid/surface objects. How should physical properties be defined and attached to volumetric datasets, and how can motion and deformation of volume objects be specified and animated? 
6. Many digitisation devices generate volumetric datasets, but not many graphics objects are available in volumetric representations. Is surface-based digitisation technologically or economically superior than volume-based digitisation? What are the obstacles to the extensive use of volume-based digitisation? 
7. In volume graphics, what is the role of the techniques developed for image processing and image processing. Can the use of frequency-domain representations of volumetric data be extended to graphics modelling and rendering in addition to data processing? 
8. Is volume graphics ready to have any impact upon a wider range graphics applications, i.e. CAD, games, films and digital art? What are the necessary technological developments in both volume-based hardware and software in order to raise the impact of volume graphics?
