    Principles and Applications of Medical Virtual Environments
    (Eurographics Association, 2004) Vidal, Franck; Bello, F.; Brodlie, K.; John, N.W.; Gould, D.; Phillips, R.; Avis, N. J.
    The medical domain offers many excellent opportunities for the application of computer graphics, visualization, and virtual environments, offering the potential to help improve healthcare and bring benefits to patients. This report provides a comprehensive overview of the state-of-the-art in this exciting field. It has been written from the perspective of both computer scientists and practicing clinicians and documents past and current successes together with the challenges that lie ahead. The report begins with a description of the commonly used imaging modalities and then details the software algorithms and hardware that allows visualization of and interaction with this data. Example applications from research projects and commercially available products are listed, including educational tools; diagnostic aids; virtual endoscopy; planning aids; guidance aids; skills training; computer augmented reality; and robotics. The final section of the report summarises the current issues and looks ahead to future developments.

    Collision Detection for Deformable Objects
    (Eurographics Association, 2004) Teschner, M.; Kimmerle, S.; Heidelberger, B.; Zachmann, G.; Raghupathi, L.; Fuhrmann, A.; Cani, M.-P.; Faure, F.; Magnenat-Thalmann, N.; Strasser, W.; Volino, P.
    Interactive environments for dynamically deforming objects play an important role in surgery simulation and entertainment technology. These environments require fast deformable models and very efficient collision handling techniques. While collision detection for rigid bodies is well-investigated, collision detection for deformable objects introduces additional challenging problems. This paper focusses on these aspects and summarizes recent research in the area of deformable collision detection. Various approaches based on bounding volume hierarchies, distance fields, and spatial partitioning are discussed. Further, image-space techniques and stochastic methods are considered. Applications in cloth modeling and surgical simulation are presented.

    Classification of Illumination Methods for Mixed Reality
    (Eurographics Association, 2004) Jacobs, Katrien; Loscos, Céline
    A mixed reality (MR) represents an environment composed both by real and virtual objects. MR applications are more and more used, for instance in surgery, architecture, cultural heritage, entertainment, etc. For some of these it is important to merge the real and virtual elements using consistent illumination. In this paper, we propose a classification of illumination methods for MR applications that aim at generating a merged environment in which illumination and shadows are consistent. Three different illumination methods can be identified: common illumination, relighting and methods based on inverse illumination. In this report a classification of the illumination methods for MR is given based on their input requirements: the amount of geometry and radiance known from the real environment. This led us to define four categories of methods that vary depending on the type of geometric model used for representing the real scene, and the different radiance information available for each point of the real scene. Various methods are described within their category. The classification points out that in general the quality of the illumination interactions increases with the amount of input information available. On the other hand, the accessibility of the method decreases since its pre-processing time increases to gather the extra information. Recent developed techniques managed to compensate unknown data with clever techniques using an iterative algorithm, hardware illumination or recent progress in stereovision. We complete the review of illumination techniques for MR with a discussion on important properties such as the possibility of interactivity or the amount of complexity in the simulated illumination.

    Acquisition, Synthesis and Rendering of Bidirectional Texture Functions
    (Eurographics Association, 2004) Müller, Gero; Meseth, Jan; Sattler, Mirko; Sarlette, Ralf; Klein, Reinhard
    One of the main challenges in computer graphics is still the realistic rendering of complex materials such as fabric or skin. The difficulty arises from the complex meso structure and reflectance behavior defining the unique look-and-feel of a material. A wide class of such realistic materials can be described as 2D-texture under varying light- and view direction namely the Bidirectional Texture Function (BTF). Since an easy and general method for modeling BTFs is not available, current research concentrates on image-based methods which rely on measured BTFs (acquired real-world data) in combination with appropriate synthesis methods. Recent results have shown that this approach greatly improves the visual quality of rendered surfaces and therefore the quality of applications such as virtual prototyping. This STAR will present in detail the state-of-the-art techniques for the main tasks involved in producing photo-realistic renderings using measured BTFs

    Visual Supercomputing - Technologies, Applications and Challenges
    (Eurographics Association, 2004) Brodlie, K.; Brooke, J.; Chen, M.; Chisnall, D.; Fewings, A.; Hughes, C.; John, N. W.; Jones, M. W.; Riding, M.; Roard, N.
    If we were to have a Grid infrastructure for visualization, what technologies would be needed to build such an infrastructure, what kind of applications would benefit from it, and what challenges are we facing in order to accomplish this goal? In this report, we make use of the term `visual supercomputing' to encapsulate a subject domain concerning the infrastructural technology for visualization. We consider a broad range of scientific and technological advances in computer graphics and visualization, which are relevant to visual supercomputing. We identify the state of the art technologies that have prepared us for building such an infrastructure. We examine a collection of applications that would benefit enormously from such an infrastructure, and discuss their technical requirements. We propose a set of challenges that may guide our strategic efforts in the coming years.

    Perceptually Adaptive Graphics
    (Eurographics Association, 2004) O’Sullivan, Carol; Howlett, Sarah; McDonnell, Rachel; Morvan, Yann; O’Conor, Keith
    In recent years, the Graphics community has come to realise the importance of taking human perception into account when striving for realism in images, animations and Virtual Environments. In May 2001, a EUROGRAPHICS/ SIGGRAPH Campfire brought together a group of researchers from various fields, including computer graphics and visualisation, psychology, neuroscience, eye-movements and medicine to discuss the future and current state of the field. Since then, many researchers have been very active in furthering the field of perceptually adaptive graphics. In this report, we outline the state of the art as discussed at that event and the progress that has been made since.
