Automatic Hierarchical Level of Detail Optimization in Computer Animation
(Blackwell Publishers Ltd and the Eurographics Association, 1997)We show that the hierarchical level of detail optimization problem is equivalent to a constrained version of the Multiple Choice Knapsack Problem, and present a new algorithm whose solution to it is at least half as good ... -
Selective Pixel Transmission for Navigating in Remote Virtual Environments
(Blackwell Publishers Ltd and the Eurographics Association, 1997)This paper presents a technique to improve the performance of a walkthrough in remote virtual environments, where a scene is rendered jointly by the server and the client, in order to reduce the network requirements as ... -
Building Telepresence Systems: Translating Science Fiction Ideas into Reality
(Blackwell Publishers Ltd and the Eurographics Association, 1997)Many people feel that at some time in the distant future it will be possible to see and interact with remote individuals so realistically that they will appear to be standing next to us, that it will also be possible for ... -
A Flexible Architecture for Virtual Humans in Networked Collaborative Virtual Environments
(Blackwell Publishers Ltd and the Eurographics Association, 1997)Complex virtual human representation provides more natural interaction and communication among participants in networked virtual environments, hence it is expected to increase the sense of being together within the same ... -
A Muscle-based Feed-forward Controller of the Human Body
(Blackwell Publishers Ltd and the Eurographics Association, 1997)There is an increasing demand for human body motion data. Motion capture and physical animation have been used to generate such data. It is, however, apparent that such methods cannot automatically generate arbitrary human ... -
Stochastic Dynamics: Simulating the Effects of Turbulence on Flexible Structures
(Blackwell Publishers Ltd and the Eurographics Association, 1997)This paper addresses the problem of realistically simulating the motion of tree-branches subjected to turbulence. Since the resulting motion is random in nature, we model it as a stochastic process. We synthesize this ... -
Finally Everyone Can Work With Highly Complex 3D Models
(Blackwell Publishers Ltd and the Eurographics Association, 1997)In the past, access to 3D databases was restricted to few specialists having the appropriate CAD skills, software, and graphics hardware.The availability of inexpensive graphics support on personal computers, the Internetâ ... -
Growing and Animating Polygonal Models of Animals
(Blackwell Publishers Ltd and the Eurographics Association, 1997)While there exist many computer models of animal bodies, as polygonal meshes and parametric surfaces, these are difficult to modify to take growth into account, or to animate. Growth data available from the literature ... -
A Multiscale Approach to Integrated Volume Segmentation and Rendering
(Blackwell Publishers Ltd and the Eurographics Association, 1997)A number of techniques have been proposed for rendering volumetric scalar data sets. Techniques have also been proposed for analyzing the three dimensional information contents of the underlying domain, but traditionally ... -
A Procedural Description of Geometric Textures by Spectral and Spatial Analysis of Profiles
(Blackwell Publishers Ltd and the Eurographics Association, 1997)In this paper we describe a method for automatically generating procedural "geometric" textures, using a hybrid (spectral and spatial) analysis of profiles (ID curves). The profile describes a certain height variation for ... -
An Algorithmic Reflectance and Transmittance Model for Plant Tissue
(Blackwell Publishers Ltd and the Eurographics Association, 1997)Recent developments in rendering have provided very realistic images. However, these images rarely show organic objects. We believe that one of the main difficulties of rendering these objects realistically is the lack of ... -
Deformable Surface Techniques for Field Visualization
(Blackwell Publishers Ltd and the Eurographics Association, 1997)Surface extraction from data fields is often used in scientific visualization, as surfaces can represent meaningful information and they are well suited for display. This paper describes a general method for localized ... -
Compression Domain Volume Rendering for Distributed Environments
(Blackwell Publishers Ltd and the Eurographics Association, 1997)This paper describes a method for volume data compression and rendering which bases on wavelet splats. The underlying concept is especially designed for distributed and networked applications, where we assume a remote ... -
Computing Volumes of Solids Enclosed by Recursive Subdivision Surfaces
(Blackwell Publishers Ltd and the Eurographics Association, 1997)The volume of a solid enclosed by a recursive subdivision surface can be approximated based on the closed-form representation of regular parts of the subdivision surface and a tight estimate of the local convex hull near ... -
Robust Computation of Intersection Graph between Two Solids
(Blackwell Publishers Ltd and the Eurographics Association, 1997)We propose a new robust algorithm for Boolean operations on solid models. The algorithm produces a consistent intersection graph between two input solids whose geometrical data are represented in floating point numbers. ... -
