    • Variational Design and Fairing of Spline Surfaces 

      Greiner, Gunther (Blackwell Science Ltd and the Eurographics Association, 1994)
      Variational principles have become quite popular in the design of free form surfaces. Among others they are used for fairing purposes. The choice of the right fairness functional is a crucial step. There is always a ...

    • Fast Dynamic Tessellation of Trimmed NURBS Surfaced1 

      Abi-Ezzi, Salim S.; Subramaniam, Srikanth (Blackwell Science Ltd and the Eurographics Association, 1994)
      Trimmed NURBS (non-uniform rational B-splines) surfaces are being increasingly used and standardized in geometric modeling applications. Fast graphical processing of trimmed NURBS at interactive speeds is absolutely essential ...

    • Spectral Data Modeling for a Lighting Application 

      Deville, Pascal M.; Merzouk, Slimane; Cazier, Dorothee; Paul, Jean C. (Blackwell Science Ltd and the Eurographics Association, 1994)
      In computer graphics, image generation uses the RGB colorimetric system. However, this system does not produce an accurate simulation of the spectral characteristics of both light and material, due to the fact that it is ...

    • 3D Visualization for 2D GIS: an Analysis of the Users Needs and a Review of Techniques* 

      Giertsen, Christopher; Lucas, Anne (Blackwell Science Ltd and the Eurographics Association, 1994)
      Most of the existing geographical information systems (GIS) make limited use of algorithms for advanced computer graphics and visualization. One explanation is that few attempts are made to identify the visualization needs ...
