  • The Mesh Propagation Algorithm for Isosurface Construction 

    Howic, C.T.; Blake, E.H. (Blackwell Science Ltd and the Eurographics Association, 1994)
    A new algorithm, Mesh Propagation, is presented for the generation of isosurfaces from three-dimensional discrete data sets. While producing the same surface mesh as that generated by a corrected Marching Cubes algorithm, ...

    Yoshida, Norimasa; Shiokawa, Masato; Yamaguchi, Fujio (Blackwell Science Ltd and the Eurographics Association, 1994)
    The technique of solid modeling is essential in CAD/CAM applications, and is currently well established. However, problems remain, such as the lack of uniformity in geometric computations and the lack of stability of Boolean ...
  • Computer Graphics System for Reproducing Three- Dimensional Shape from Idea Sketch 

    Akeo, Makoto; Hashimoto, Hiroshi; Kobayashi, Taisuke; Shibusawa, Tetsuo (Blackwell Science Ltd and the Eurographics Association, 1994)
    This paper describes the technical features and method of implementation of our designer support system which enables reproducing a three-dimensional shape from an idea sketch speedily and modifying the reproduced shape ...
  • Sketching 3D models with 2D interaction devices 

    Branco, Vasco; Costa, Antonio; Ferreira, F. Nunes (Blackwell Science Ltd and the Eurographics Association, 1994)
    The creation of a 3D shape using CAD tools, namely solid modelers, is difficult and time-consuming. Therefore, these systems are kept away from the conceptual phases of design, perhaps the most important in any product ...
  • Cross Scan Buffer and its Applications 

    Tanaka, Toshimitsu; Takahashi, Tokiichiro (Blackwell Science Ltd and the Eurographics Association, 1994)
    We propose the Cross Scanline Buffer which preserves the result of hidden surface removal as performed by the Cross Scanline Algorithm. The Cross Scan Buffer reduces image re-generation time and eliminates aliasing artifacts ...
  • How to Render Frames and Influence People 

    Strothotte, Thomas; Preim, Bernhard; Raab, Andreas; Schumann, Jutta; Forsey, David R. (Blackwell Science Ltd and the Eurographics Association, 1994)
    Rendering systems generally treat the production of images as an objective process governed by the laws of physics. However, perception and understanding on the part of viewers are subjective processes influenced by a ...
  • A Paradigm for the Robust Design of Algorithms for Geometric Modeling 

    Agrawal, Amitabh; Requicha, Aristides A. G. (Blackwell Science Ltd and the Eurographics Association, 1994)
    Geometric modelers are becoming faster and more powerful, but they still suffer from reliability problems because of floating point errors. Previous work in the field of robust geometric modeling tends to be problem specific ...
  • Reducing The Latency In Head-Mounted Displays By A Novel Prediction Method Using Grey System Theory 

    Wu, Jiann-Rong; Ouhyoung, Ming (Blackwell Science Ltd and the Eurographics Association, 1994)
    In this paper we propose a novel prediction method for the head motion using Grey System theory, where a 6D tracker is attached to an HMD on a user s head in virtual reality applications. Our prediction method using Grey ...
  • Implementing RenderMan - Practice, Problems and Enhancements 

    Slusallek, Philipp; Pflaum, Thomas; Seidel, Hans-Peter (Blackwell Science Ltd and the Eurographics Association, 1994)
    The RenderMan interface has been proposed as a general interface to rendering systems, yet only a few implementations of the interface exist. In this paper we describe the implementation of the RenderMan interface on a ...
  • Fast Wavelet Radiosity Method 

    Pattanaik, Sumanta N.; Bouatouch, Kadi (Blackwell Science Ltd and the Eurographics Association, 1994)
    Wavelet analysis has been found [1] to be very useful for functional representation and accurate global solution of radiosity. In radiosity we deal with functions in 2D and 4D spaces. Under such conditions, the biggest ...
  • A Median Cut Algorithm for Efficient Sampling of Radiosity Functions 

    Feda, Martin; Purgathofer, Werner (Blackwell Science Ltd and the Eurographics Association, 1994)
    This paper presents an efficient method for sampling the illumination functions in higher order radiosity algorithms. In such algorithms, the illumination function is not assumed to be constant across each patch, but it ...
  • Adaptive mesh generation for progressive radiosity: A ray-tracing based algorithm. 

    PAULIN, Mathias; JESSEL, Jean-Pierre (Blackwell Science Ltd and the Eurographics Association, 1994)
    The radiosity method is one of the most popular rendering algorithms. It allows to simulate interreflections of light accurately between surfaces as energy transfers are well designed. However, this algorithm and its ...
  • PREMO - An Initial Approach to a Formal Definition
