    • Dynamics and Chaos: The Spherical Pendulum 

      Palacios, Antonio; Gross, Lee M.; Rockwood, Alyn P. (Blackwell Science Ltd and the Eurographics Association, 1996)
      All but the simplest of dynamical systems contain nonlinearities that play an important role in modeling and simulating physical systems. They create unpredictable (chaotic) behavior that is often hidden or neglected in ...

    • Interactive Rendering of CSG Models 

      Wiegand, T. E (Blackwell Science Ltd and the Eurographics Association, 1996)
      We describe a CSG rendering algorithm that requires no evaluation of the CSG tree beyond normalization and pruning. It renders directly from the normalized CSG tree and primitives described (to the graphics system) by their ...

    • SCROOGE:Perceptually-Driven Polygon Reduction 

      Reddy, M. (Blackwell Science Ltd and the Eurographics Association, 1996)
      Many real-time 3D graphics renderers represent each object as a collection of simple polygons. The complexity of this polygon structure is of practical relevance because it can manifestly affect the performance of the ...

    • Topologically exact evaluation of polyhedra defined in CSG with loose primitives 

      Banerjee, Raja (P.K.); Rossignac, Jarek R. (Blackwell Science Ltd and the Eurographics Association, 1996)
      Floating point round-off causes erroneous and inconsistent decisions in geometric modelling algorithms. These errors lead to the generation of topologically invalid boundary models for CSG objects and significantly reduce ...

    • A Unified, Object-Oriented Graphics System and Software Architecture for Visualising CAD/CAM Presentations 

      Kochhar, Sandeep; Hall, Jim (Blackwell Science Ltd and the Eurographics Association, 1996)
      Most object-oriented graphics systems (OOGS) either support general purpose graphics capabilities (drawing editors, ray tracing, etc.), or have targeted specific areas of computer graphics, for example, interface building, ...

    • Using a Convex Pyramid to Bound Surface Normal Vectors 

      Daniel, M. (Blackwell Science Ltd and the Eurographics Association, 1996)
      Determining a tight bounding volume of all the surface normal vectors is of interest in surface modelling especially for intersection problems, in order to detect closed intersection curves. It is also important to determine ...
