    • A Fast Algorithm for Inverse Colormap Computation 

      Brun, L.; Secroun, C. (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      The inverse colormap operation is the process which allows an image to be displayed with a limited set of colors. In order to obtain a minimal visual distortion between the input image annd the one displayed, inverse ...
    • Fast Collision Detection Algorithms with Applications to Particle Flow 

      Vemuri, B. C.; Cao, Y.; Chen, L. (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      In this paper, we present efficient algorithms for collision detection of arbitrarily shaped rigid moving objects in a variety of interactive as well as non-interactive environments. The algorithms primarily consist of two ...
    • Fast Feature-Based Metamorphosis and Operator Design 

      Lee, Tong-Yee; Lin, Young-Ching; Sun, Y.N.; Lin, Leeween (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      Metamorphosis is a powerful visual technique, for producing interesting transition between two images or volume data. Image or volume metamorphosis using simple features provides flexible and easy control of visual effect. ...
    • Fifth Eurographics Workshop on Design Specification and Verification of Interactive Systems, Abingdon, UK, June 3-5 1998 

      Markopoulos, P.; Johnson, P. (Blackwell Publishers Ltd and the Eurographics Association, 1998)
    • A Framework for Synchronized Editing of Multiple Curve Representations 

      Grimm, Cindy; Ayers, Matthew (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      Editing curves and surfaces is difficult in part because their mathematical representations rarely correspond to most peopleâ s idea of a curve or surface. The implementation (and hence, behavior) of most manipulation ...
    • Frontiers in User-Computer Interaction 

      Van Dam, Andries (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      In this age of (near-)adequate computing power, the power and usability of the user interface is as key to an applicationâ s success as its functionality. Most of the code in modern desktop productivity applications resides ...
    • Getting Rid of Links in Hierarchical Radiosity 

      Stamminger, M.; Schirmacher, H.; Slusallek, Ph.; Seidel, H.-P. (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      Hierarchical radiosity with clustering has positioned itself as one of the most efficient algorithms for computing global illumination in non-trivial environments. However, using hierarchical radiosity for complex scenes ...
    • Importance Driven Halftoning 

      Streit, L.; Buchanan, J. (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      Most halftoning techniques have been primarily concerned with achieving an accurate reproduction of local gray-scale intensities while avoiding the introduction of artifacts. A secondary concern in halftoning has been the ...
    • Importance Driven Texture Coordinate Optimization 

      Sloan, Peter-Pike J.; Weinstein, David M.; Brederson, J. (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      Traditionally, texture coordinates have been generated based solely on the modelâ s geometry, often even before a modelâ s textures have been created. With the arrival of new technologies, such as 3D paint programs, ...
    • Incident Light Metering in Computer Graphics 

      Neumann, Laszlo; Matkovic, Kresimir; Neumann, Attila; Purgathofer, Werner (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      Every rendering process consists of two steps. The first is the computing of luminance values by methods like ray tracing or radiosity, and the second step is the mapping of the computed values to values appropriate for ...
    • Interactive 3D Morphing 

      Bao, Hujun; Peng, Qunsheng (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      A new 3D morphing algorithm for polyhedral objects with the same genus is presented in the paper. Our main contribution is an efficient and general algorithm for setting up the vertex correspondence between the polyhedra. ...
    • Interactive Construction and Animation of Layered Elastically Deformable Characters 

      Turner, Russell; Gobbetti, Enrico (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      An interactive system is described for creating and animating deformable 3D characters. By using a hybrid layered model of kinematic and physics-based components together with an immersive 3D direct manipulation interface, ...

    • A Light Hierarchy for Fast Rendering of Scenes with Many Lights 

      Paquette, Eric; Poulin, Pierre; Drettakis, George (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      We introduce a new data structure in the form of a light hierarchy for efficiently ray-tracing scenes with many light sources. An octree is constructed with the point light sources in a scene. Each node represents all the ...
    • Mass-Spring Simulation using Adaptive Non-Active Points 

      Howlett, P.; Hewitt, W.T. (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      This paper introduces an adaptive component to a mass-spring system as used in the modelling of cloth for computer animation. The new method introduces non-active points to the model which can adapt the shape of the cloth ...
    • Maximum Intensity Projection Using Splatting in Sheared Object Space 

      Cai, Wenli; Sakas, Georgios (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      In this paper we present a new Maximum Intensity Projection (MIP) algorithm which was implemented employing splatting in a shear-warp context. This algorithm renders a MIP image by first splatting each voxel on two ...
    • Metro: Measuring Error on Simplified Surfaces 

      Cignoni, P.; Rocchini, C.; Scopigno, R. (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      This paper presents a new tool, Metro, designed to compensate for a deficiency in many simplification methods proposed in literature. Metro allows one to compare the difference between a pair of surfaces (e.g. a triangulated ...
