An Advanced Color Representation for Lossy Compression of CMYK Prepress Images
(Blackwell Publishers Ltd and the Eurographics Association, 2000)CMYK color images are used extensively in prepress applications. When compressing those color images one has to deal with four different color channels. Usually compression algorithms only take into account the spatial ... -

Efficient Glossy Global Illumination with Interactive Viewing
(Blackwell Publishers Ltd and the Eurographics Association, 2000)The ability to perform interactive walkthroughs of global illumination solutions including glossy effects is a challenging open problem. In this paper we overcome certain limitations of previous approaches. We first introduce ... -

Generating Consistent Motion Transition via Decoupled Framespace Interpolation
(Blackwell Publishers Ltd and the Eurographics Association, 2000)The framespace interpolation algorithm abstracts motion sequences as 1D signals, and interpolates between them to create higher dimension signals, with weights drawn from a user specified curve in a bounded region. We ... -
Motion Balance Filtering
(Blackwell Publishers Ltd and the Eurographics Association, 2000)This paper presents a new technique called motion balance filtering, which corrects an unbalanced motion to a balanced one while preserving the original motion characteristics as much as possible. Differently from previous ... -
Automatic Surface Reconstruction from Point Sets in Space
(Blackwell Publishers Ltd and the Eurographics Association, 2000)In this paper an algorithm is proposed that takes as input a generic set of unorganized points, sampled on a real object, and returns a closed interpolating surface. Specifically, this method generates a closed 2-manifold ... -
A Vector-based Representation for Image Warping
(Blackwell Publishers Ltd and the Eurographics Association, 2000)A method for image analysis, representation and re-synthesis is introduced. Unlike other schemes it is not pixel based but rather represents a picture as vector data, from which an altered version of the original image can ... -
Real Time Local Approximation of Deformations using Rotations
(Blackwell Publishers Ltd and the Eurographics Association, 2000)Additional realism can be achieved in computer generated images using smooth and increasingly complex deformations. Though significant effort has been spent on improving these deformations, no general method has been ... -
Surface Reconstruction based on Lower Dimensional Localized Delaunay Triangulation
(Blackwell Publishers Ltd and the Eurographics Association, 2000)We present a fast, memory efficient algorithm that generates a manifold triangular mesh S passing through a set of unorganized points P R 3. Nothing is assumed about the geometry, topology or presence of boundaries in the ... -
LCTS: Ray Shooting using Longest Common Traversal Sequences
(Blackwell Publishers Ltd and the Eurographics Association, 2000)We describe two new techniques of ray shooting acceleration that exploit the traversal coherence of a spatial hierarchy. The first technique determines a sequence of adjacent leaf-cells of the hierarchy that is pierced by ... -
Integrating Occlusion Culling and Levels of Detail through Hardly-Visible Sets
(Blackwell Publishers Ltd and the Eurographics Association, 2000)Occlusion culling and level-of-detail rendering have become two powerful tools for accelerating the handling of very large models in real-time visualization applications. We present a framework that combines both techniques ... -
Floating Points: A Method for Computing Stipple Drawings
(Blackwell Publishers Ltd and the Eurographics Association, 2000)We present a method for computer generated pen-and-ink illustrations by the simulation of stippling. In a stipple drawing, dots are used to represent tone and also material of surfaces. We create such drawings by generating ... -
Directional Discretized Occluders for Accelerated Occlusion Culling
(Blackwell Publishers Ltd and the Eurographics Association, 2000)We present a technique for accelerating the rendering of high depth-complexity scenes. In a preprocessing stage, we approximate the input model with a hierarchical data structure and compute simple view-dependent polygonal ... -
An Interactive Approach to Point Cloud Triangulation
(Blackwell Publishers Ltd and the Eurographics Association, 2000)We present an interactive system for the generation of high quality triangle meshes that allows us to handle hybrid geometry (point clouds, polygons,. . .) as input data. In order to be able to robustly process huge data ... -
Efficient Algorithms for Computing Conservative Portal Visibility Information
(Blackwell Publishers Ltd and the Eurographics Association, 2000)The number of polygons in realistic architectural models is many more than can be rendered at interactive frame rates. Typically, however, due to occlusion by opaque surfaces (e.g., walls), only small fractions of such ... -
Automatic Generation of Virtual Woodblocks and Multicolor Woodblock Printing
(Blackwell Publishers Ltd and the Eurographics Association, 2000)In this paper, we study a method to synthesize a multicolor virtual woodblock print by using several virtual woodblocks. It consists of two sections: carving and printing, to synthesize a virtual print. In the carving ... -
Binding Virtual Environments to Toolkit Capabilities
(Blackwell Publishers Ltd and the Eurographics Association, 2000)There are many toolkits and development environments that aid the process of constructing virtual environment applications. Many of these development environments encourage customising a virtual environment's design while ... -
Modelling virtual cities dedicated to behavioural animation
(Blackwell Publishers Ltd and the Eurographics Association, 2000)In order to populate virtual cities, it is necessary to specify the behaviour of dynamic entities such as pedestrians or car drivers. Since a complete mental model based on vision and image processing cannot be constructed ... -
Observational Models of Graphite Pencil Materials
(Blackwell Publishers Ltd and the Eurographics Association, 2000)This paper presents models for graphite pencil, drawing paper, blenders, and kneaded eraser that produce realistic looking pencil marks, textures, and tones. Our models are based on an observation of how lead pencils ...
