    The paper presents an interactive visualization tool, Archimedean Kaleidoscope (AK), aimed at supporting a learner's exploration of polyhedra. AK uses metamorphosis as a technique to help support the learner's mental construction of relationships among different polyhedra. AK uses the symmetric nature of the platonic solids as the foundation for exploring the way in which polyhedra are related. Th... View full abstract»

  • An improved scan-line algorithm for display of CSG models

    Publication Year: 2001, Page(s):477 - 482
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (600 KB) | HTML iconHTML

    A scan-line algorithm uses a one-dimensional set operation instead of a depth comparison to find a visible surface of the object shape defined by constructive solid geometry (CSG). Interactive solid modelers employing a scan-line algorithm require considerable computing time in repeated construction and destruction of parts of the CSG object models during the design process. We discuss three steps... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (288 KB) | HTML iconHTML

    Rational Bezier curves provide flexibility in curve design. The goal of this paper is to perform error analysis of Farin's (1983, 1986) algorithm for the evaluation of these curves. It is shown that a similar error analysis can be applied for the algorithms in rational spaces obtained from spaces admitting shape preserving representations View full abstract»

    One of the main benefits of object orientation is the concept of inheritance which allows for the derivation of new types/classes from existing ones. Within commonly used object oriented languages, inheritance is usually directed to attributes and method signatures, only. Considering languages providing means for the specification of object life cycles, the concept of inheritance needs to be exten... View full abstract»

    We have proposed a new edge collapse simplification algorithm that can produce efficiently high quality approximations of closed manifold surface models. To reduce the number of triangular faces in a polygonal model, a sequence of edge collapses is performed and to choose the appropriate sequence of edge collapses, we have introduced a new error metric based on a quantity proportional to the volum...
