A New Method of Image Mosaicking and Its Application to Cultural Heritage Representation

Cortelazzo, G.M.; Lucchese, L. (Blackwell Publishers Ltd and the Eurographics Association, 1999)

This paper presents an original two-step procedure for estimating projective transformations between pairs of images: first, the transformation between the images is approximated as an affine transformation; second, this ...

Active Storytelling

Glassner, Andrew (Blackwell Publishers Ltd and the Eurographics Association, 1999)

Virtual Dunhuang Art Cave: A Cave within a CAVE

Lutz, B.; Weintke, M. (Blackwell Publishers Ltd and the Eurographics Association, 1999)

Virtual Reality can present historical places in a three-dimensional and interactive way, giving visitors a photorealistic impression of objects. Not only existing scenarios can be shown, but VR can also be used to rebuild ...

Stochastic Iteration for Non-diffuse Global Illumination

Szirmay-Kalos, Laszlo (Blackwell Publishers Ltd and the Eurographics Association, 1999)

This paper presents a single-pass, view-dependent method to solve the rendering equation, using a stochastic iterational scheme where the transport operator is selected randomly in each iteration. The requirements of ...

Approximate Line Scan-Conversion and Antialiasing

Chen, Jim X.; Wang, Xusheng (Blackwell Publishers Ltd and the Eurographics Association, 1999)

Modeling and Rendering Escher-Like Impossible Scenes

Savransky, Guillermo; Dimerman, Dan; Gotsman, Craig (Blackwell Publishers Ltd and the Eurographics Association, 1999)

Inspired by the drawings of "impossible" objects by artists such as M.C. Escher, we describe a mathematical theory which captures some of the underlying principles of their work. Using this theory, we show how impossible ...

Multiresolution Curve and Surface Representation: Reversing Subdivision Rules by Least-Squares Data Fitting

Samavati, Faramarz F.; Bartels, Richard H. (Blackwell Publishers Ltd and the Eurographics Association, 1999)

This work explores how three techniques for defining and representing curves and surfaces can be related efficiently. The techniques are subdivision, least-squares data fitting, and wavelets. We show how least-squares data ...

Metis - An Object-Oriented Toolkit for Constructing Virtual Reality Applications

Turner, Russell; Li, Song; Gobbetti, Enrico (Blackwell Publishers Ltd and the Eurographics Association, 1999)

Virtual reality systems provide realistic look and feel by seamlessly integrating three-dimensional input and output devices. One software architecture approach to constructing such systems is to distribute the application ...

A Progressive Algorithm for Three Point Transport

Dumont, Reynald; Bouatouch, Kadi; Gosselin, Philippe (Blackwell Publishers Ltd and the Eurographics Association, 1999)

When computing global illumination in environments made up of surfaces with general Bidirectional Reflection Distribution Functions, a three point formulation of the rendering equation can be used. Brute-force algorithms ...

Tetrahedra Based Adaptive Polygonization of Implicit Surface Patches

Hui, K. C.; Jiang, Z. H. (Blackwell Publishers Ltd and the Eurographics Association, 1999)

This paper presents a tetrahedra based adaptive polygonization technique for tessellating implicit surface patches. An implicit surface patch is defined as an implicit surface bounded by its intersections with a set of ...

Editorial

Coquillart, Sabine; Seidel, Hans-Peter (Blackwell Publishers Ltd and the Eurographics Association, 1999)

Multi-layered impostors for accelerated rendering

Decoret, Xavier; Sillion, Francois; Schaufler, Gernot; Dorsey, Julie (Blackwell Publishers Ltd and the Eurographics Association, 1999)

This paper describes the successful combination of pre-generated and dynamically updated image-based representations to accelerate the visualization of complex virtual environments. We introduce a new type of impostor, ...
