  • A Library for Developing PHIGS Programming Tools in a PEX Environment 

    Wainer, Michael; Tan, Ting (Blackwell Science Ltd and the Eurographics Association, 1993)
    The merger of three-dimensional graphics with the X Window System has recently been standardized by adapting PHIGS, the Programmer s Hierarchical Interactive Graphics System, to the X Window System with PEX, the PHIGS ...
  • Ray Tracing an Octree: Numerical Evaluation of the First Intersection 

    Gargantini, I.; Atkinson, H. H. (Blackwell Science Ltd and the Eurographics Association, 1993)
  • Spanning a C1-Surface over a Given Wireframe 

    Tokumasu, Shinji; Harashima, Ichirou; Nakajima, Norihiro (Blackwell Science Ltd and the Eurographics Association, 1993)
    A problem of spanning a surface of C1 continuity (C1-surface) over a given wireframe is introduced. By exploiting the concept of a super surface patch introduced in an earlier paper, we proved the existence of an approximate, ...
  • The Determination of Form-Factors by Lookup Table 

    Sun, Jizhou; Zou, L.Q.; Grimsdale, R.L. (Blackwell Science Ltd and the Eurographics Association, 1993)
    Current methods for computer image synthesis using the radiosity algorithm rely heavily on the calculation of geometrical properties, known as form-factors, which quantify the energy exchange between pairs of surfaces in ...
