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 ... -
Collaborative Virtual Simulation Environment for Radiotherapy Treatment Planning
(Blackwell Publishers Ltd and the Eurographics Association, 2000)The simulation of Radiotherapy Treatment Planning (RTP) is a normal procedure in oncology clinics carried out on a Simulator machine. The Virtual Simulation of RTP replaces the real Simulator machine with a virtual one by ... -
Color Distribution - A New Approach to Texture Compression
(Blackwell Publishers Ltd and the Eurographics Association, 2000)Texture compression is recently one of the most important topics of 3D scene rendering techniques, because it allows rendering more complicated high-resolution scenes. However, because of some special requirements for these ... -
Colour Section
(Blackwell Publishers Ltd and the Eurographics Association, 2000) -
Context-based Space Filling Curves
(Blackwell Publishers Ltd and the Eurographics Association, 2000)A context-based scanning technique for images is presented. An image is scanned along a context-based space filling curve that is computed so as to exploit inherent coherence in the image. The resulting one-dimensional ... -
Direct Manipulation and Interactive Sculpting of PDE Surfaces
(Blackwell Publishers Ltd and the Eurographics Association, 2000)This paper presents an integrated approach and a unified algorithm that combine the benefits of PDE surfaces and powerful physics-based modeling techniques within one single modeling framework, in order to realize the full ... -
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 ... -
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 ... -
External Memory View-Dependent Simplification
(Blackwell Publishers Ltd and the Eurographics Association, 2000)In this paper, we propose a novel external-memory algorithm to support view-dependent simplification for datasets much larger than main memory. In the preprocessing phase, we use a new spanned sub-meshes simplification ... -
Fast Volume Rendering and Data Classification Using Multiresolution in Min-Max Octrees
(Blackwell Publishers Ltd and the Eurographics Association, 2000) -
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 ... -
Generating Animatable 3D Virtual Humans from Photographs
(Blackwell Publishers Ltd and the Eurographics Association, 2000)We present an easy, practical and efficient full body cloning methodology. This system utilizes photos taken from the front, side and back of a person in any given imaging environment without requiring a special background ... -
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 ... -
Graceful Degradation of Collision Handling in Physically Based Animation
(Blackwell Publishers Ltd and the Eurographics Association, 2000)Interactive simulation is made possible in many applications by simplifying or culling the finer details that would make real-time performance impossible. This paper examines detail simplification in the specific problem ... -
Gradient Estimation in Volume Data using 4D Linear Regression
(Blackwell Publishers Ltd and the Eurographics Association, 2000)In this paper a new gradient estimation method is presented which is based on linear regression. Previous contextual shading techniques try to fit an approximate function to a set of surface points in the neighborhood of ... -
Haptic Cues for Image Disambiguation
(Blackwell Publishers Ltd and the Eurographics Association, 2000)Haptic interfaces represent a revolution in human computer interface technology since they make it possible for users to touch and manipulate virtual objects. In this work we describe a cross-model interaction experiment ... -
The Impulse Graph: A New Dynamic Structure For Global Collisions
(Blackwell Publishers Ltd and the Eurographics Association, 2000)In interactive virtual environments and dynamic simulations, collisions between complex objects and articulated bodies may occur simultaneously at multiple points or regions of interference. Many solutions to the collision ... -
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 ... -
Integration of Multidimensional Interaction Devices in Real-Time Computer Graphics Applications
(Blackwell Publishers Ltd and the Eurographics Association, 2000)Modern CAD/CAM and Virtual Reality applications cannot be imagined without the new class of interaction devices allowing the user direct interaction with computer generated scenes. Integrating such devices into existing ... -
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 ...
