    Exact Isosurfaces for Marching Cubes
    (Blackwell Publishers Ltd and the Eurographics Association, 2002) Theisel, Holger
    In this paper we study the exact contours of a piecewise trilinear scalar field. We show how to represent these contours exactly as trimmed surfaces of triangular rational cubic Bezier patches. As part of this, we introduce an extension of the marching cubes algorithm which gives a topologically exact triangular approximation of the contours for any case. Finally, we modify the exact contours to be globally G1 continuous without changing their topologies. We test the algorithm on both theoretical and practical data sets.

    Psychovisual Evaluation of Lossy CMYK Image Compression for Printing Applications
    (Blackwell Publishers Ltd and the Eurographics Association, 2002) Denecker, K.; De Neve, P.; Van Assche, S.; Van de Walle, R.; Lemahieu, I.; Philips, W.
    In the digital prepress workflow, images are represented in the CMYK colour space. Lossy image compression alleviates the need for high storage and bandwidth capacities, resulting from the high spatial and tonal resolution. After the image has been printed on paper, the introduced visual quality loss should not be noticeable to a human observer. Since visual image quality depends on the compression algorithm both quantitatively and qualitatively, and since no visual image quality models incorporating the end-to-end image reproduction process are satisfactory, an experimental comparison is the only viable way to quantify subjective image quality. This paper presents the results from an intensive psychovisual study based on a two-alternative forced-choice approach involving 164 people, with expert and non-expert observers distinguished. The primary goal is to evaluate two previously published adaptations of JPEG to CMYK images, and to determine a visually lossless compression ratio threshold for typical printing applications. The improvements are based on tonal decorrelation and overlapping block transforms. Results on three typical prepress test images indicate that the proposed adaptations are useful and that for the investigated printing configuration, compression ratios up to 20 can be used safely.

    A Coherence-based Collision Detection Method for Dressed Human Simulation
    (Blackwell Publishers Ltd and the Eurographics Association, 2002) Zhang, Dongliang; Yuen, Matthew
    In this paper, paper we present a coherence-based method to detect collisions between the garment and human model for dressed human simulations. Based on the property of coherence, collisions can be rapidly detected by tracking the movement of the most likely geometric elements to collide. The voxel technique is employed to quickly identify the potential collision region. Experimental results show that our method is very efficient.

    Web 2D Graphics File Formats
    (Blackwell Publishers Ltd and the Eurographics Association, 2002) Duce, David; Herman, Ivan; Hopgood, Bob
    The earliest Web browsers focussed on the display of textual information. When graphics were added, essentially only image graphics and image file formats were supported. For a significant range of applications, image graphics has severe limitations, for example in terms of file size, download time and inability to interact with and modify the graphics client-side. Vector graphics may be more appropriate in these cases, and this has become possible through the introduction of the WebCGM and Scalable Vector Graphics (SVG) formats, both of which are open standards, the former from ISO/IEC and W3C and the latter from W3C. This paper reviews the background to Web graphics, presents the WebCGM file format, and gives a more detailed exposition of the most recent format, SVG. The paper concludes with reflections on the current state of this area and future prospects.

    Techniques for Realistic Visualization of Fluids: A Survey
    (Blackwell Publishers Ltd and the Eurographics Association, 2002) Adabala, Neeharika; Manohar, Swami
    Visualization of fluids has wide applications in science, engineering and entertainment. Various methodologies of visualizing fluids have evolved which emphasize on capturing different aspects of the fluids accurately. In this survey the existing methods for realistic visualization of fluids are reviewed. The approaches are classified based on the key concept they rely on for fluid modeling. This classification allows for easy selection of the method to be adopted for visualization given an application. It also enables identification of alternative techniques for fluid modeling.
