Tessellation of Curved Surfaces under Highly Varying Transformations
(Eurographics Association, 1991)We pursue the problem of step size determination for tessellating arbitrary degree polynomial and rational Bezier patches, under highly varying modeling and viewing transformations, to within post-viewing size and/or ... -
A Testbed for Architectural Modeling
(Eurographics Association, 1991)This paper describes the philosophy and implementation of a modeling system that is easy to use yet addresses some of the difficulties of design. It does this by supporting concurrent schematic and geometric representations, ... -
A Testbed for Image Synthesis
(Eurographics Association, 1991)Image Synthesis research combines new ideas with existing techniques. A collection of software modules that provide such techniques is extremely useful for simplifying the development process. We describe the design and ... -
Time Complexity of Monte Carlo Radiosity
(Eurographics Association, 1991)The time complexity of Monte Carlo radiosity is discussed, and a proof is given that the expected number of rays required to produce a satisfactory radiosity solution for N zones is O(N). A satisfactory solution is defined ... -
Timewarps: A Temporal Reparameterization Paradigm for Parametric Animation
(Eurographics Association, 1991)The ability to reparameterize the temporal axis in an animated sequence is a powerful and underexplored tool. Timewarps are described as extensions to previous work and the advantages of this tool are outlined. Timewarps ... -
Using temporal and spatial coherence for accelerating the calculation of animation sequences
(Eurographics Association, 1991)Ray tracing is a well known technique for generating realistic images. One of the major drawbacks of this approach are the extensive computational requirements for image calculation. When generating animation sequences ... -
Validity Issues for Modular Boundary Models
(Eurographics Association, 1991)Modular boundary models are a class of solid models which describe a solid object as a collection of face-abutting object parts, called components. The Face-to-Face Composition (FFC) model is a specific model of this class, ... -
Variable-Radius Blending by Using Gregory Patches in Geo- metric Modeling
(Eurographics Association, 1991)Blending surfaces, which connect two curved surfaces smoothly, often appear in geometric modeling. Many of the blending surfaces are variable-radius blends. Variableradius blending surfaces are very important in the design ...
