    Rendering and Visualization in Affordable Parallel Environments
    (Eurographics Association, 1998) Bartz, Dirk; Silva, Claudio; Schneider, Bengt-Olaf
    The scope of this full-day tutorial is the use of low and medium-cost parallel environments (less than US $ 60K) for high-speed rendering and visualization. In particular, our focus is on the parallel graphics programming of multi-processor PCs or workstations, and networks of both. The current technology push in the consumer market for graphics hardware, small multiprocessor machines, and fast networks is bound to make all of these components less expensive. In this tutorial, attendees will learn how to leverage these advances in consumer hardware to achieve faster rendering by using parallel rendering algorithms, and off-the-shelf software systems. This course will briefly touch the necessary tools to make basic use of this technology: parallel programming paradigms (shared memory, message passing) and parallel rendering algorithms (including image-, object-, and time- space parallelism). Advantages and issues of the different methods will be discussed on several examples of polygonal graphics and volume rendering.

    Advanced Application of Volume Visualization Methods in Medicine
    (Eurographics Association, 1998) Sakas, G.; Pommert, A.
    Tomographic medical imaging techniques have become more popular in recent years. The wide availability of CT, MRI and Ultrasound in most large hospitals results in a rapidly increasing number of examinations with these devices. The State of The Art Report summarises the application of techniques developed over the recent years for visualising volumetric medical data common in modern medical imaging modalities such as CT, MRA, MRI, Nuclear Medicine, 3D-Ultrasound, Laser Confocal Microscopy etc. Although all of the modalities listed above provide "slices of the body", significant differences exist between the image content of each modality. The focus of the Report is be less in explaining algorithms and rendering techniques, but rather to point out their applicability, benefits, and potential in the medical environment. In the first part, methods for all steps of the volume visualization pipeline from data preprocessing to object display are reviewed, with special emphasis on data structures, segmentation, and surface- and volume-based rendering. Furthermore, multimodality matching, intervention rehearsal, and aspects of image quality are discussed. In the second part applications are illustrated from the areas of craniofacial surgery, traumatology, neurosurgery, radiotherapy, and medical education. Furtherly, some new applications of volumetric methods are presented: 3D ultrasound, laser confocal datasets, and 3D-reconstruction of cardiological datasets, i.e. vessels as well as ventricles. These new volumetric methods are currently under development but due to their enormeous application potential they are expected to be clinically accepted within the next years.

    A Subdivision Scheme for Smooth Interpolation of Quad-Mesh Data
    (Eurographics Association, 1998) Kobbelt, L. P.
    A simple interpolatory subdivision scheme for quadrilateral nets with arbitrary topology is presented which generates C1 surfaces in the limit. The scheme satisfies important requirements for practical applications in computer graphics and engineering. These requirements include the necessity to generate smooth surfaces with local creases and cusps. The scheme can be applied to open nets in which case it generates boundary curves that allow a C0- join of several subdivision patches. Due to the local support of the scheme, adaptive refinement strategies can be applied. We present a simple device to preserve the consistency of such adaptively refined nets.

    Introduction to Programming with Java 3D
    (Eurographics Association, 1998) Nadeau, D. R.; Sowizral, H. A.
    Java 3D is a new cross-platform API for developing 3D graphics applications in Java. Java 3D’s feature set has been designed to enable quick development of complex 3D applications, and at the same time enable fast and efficient implementations on a variety of platforms, from PCs to workstations. Using Java 3D, software developers can build cross-platform applications that build 3D scenes programmatically, or via loading 3D content from VRML, OBJ, and/or other external files. The Java 3D API includes a rich feature set for building shapes, composing behaviors, interacting with the user, and controlling rendering details. Participants in this tutorial will learn the concepts behind Java 3D, the Java 3D class hierarchy, typical usage patterns, ways of avoiding common mistakes, animation and scene design techniques, and tricks for increasing performance and realism.

    Introduction to VRML 97
    (Eurographics Association, 1998) Nadeau, D. R.
    VRML (the Virtual Reality Modeling Language) is an international standard for describing 3-D shapes and scenery on the World Wide Web. VRML’s technology has very broad applicability, including web-based entertainment, distributed visualization, 3-D user interfaces to remote web resources, 3-D collaborative environments, interactive simulations for education, virtual museums, virtual retail spaces, and more. VRML is a key technology shaping the future of the web. Participants in this tutorial will learn how to use VRML 97 (a.k.a. ISO VRML, VRML 2.0, and Moving Worlds) to author their own 3-D virtual worlds on the World Wide Web. Participants will learn VRML concepts and terminology, and be introduced to VRML’s text format syntax. Participants also will learn tips and techniques for increasing performance and realism. The tutorial includes numerous VRML examples and information on where to find out more about VRML features and use.
