Three-Dimensional Modeling and Effects on Still Images
(Blackwell Science Ltd and the Eurographics Association, 1996)
Designers and creative artists use computer graphics and image processing effects on stall photographs in application areas such as advertising entertainment broadcasting and the arts Most of the effects available in ...
An Energy-Based Approach for Contact Force Computation
(Blackwell Science Ltd and the Eurographics Association, 1996)
A new approach for computing resting contact forces between solids is presented, which handles both static and sliding friction, while avoiding the problems arising from previous approaches. Each iteration provides values ...
Generation of Smooth Surfaces by Controlling Curvature Variation
(Blackwell Science Ltd and the Eurographics Association, 1996)
To satisfy a designer s intention for constructing aesthetic shapes such as automotive bodies, we propose a surface generation method. In the surface design process, designers determine shapes according to their great ...
A Platform for User-Tailored Interaction Development in 2D, 3D, and VR
(Blackwell Science Ltd and the Eurographics Association, 1996)
The discussion on the advantages and disadvantages of 2D, 3D, and VR interfaces and their applicability to different types of systems, users, and information led to a series of stand-alone implementations that lack the ...
Reusable Radiosity Objects
(Blackwell Science Ltd and the Eurographics Association, 1996)
Because of the view independence and photo realistic image generation in a diffuse environment, radiosity is suitable for an interactive walk through system. The drawback of radiosity is that it is time-consuming in form ...
A Three Dimensional Image Cache for Virtual Reality
(Blackwell Science Ltd and the Eurographics Association, 1996)
Despite recent advances in rendering hardware, large and complex virtual environments cannot be displayed with a sufficiently highframe rate, because of limitations in the available rendering performance.This paper presents ...
Demand-Driven Geometry Transmission for Distributed Virtual Environments
(Blackwell Science Ltd and the Eurographics Association, 1996)
We present a strategy for rendering in distributed virtual environments. A geometry database is maintained by a server, while users invoke individual clients to interact with the environment. Instead of downloading a ...
Matching and Interpolation of Shapes using Unions of Circles
(Blackwell Science Ltd and the Eurographics Association, 1996)
While the notion of shape of an object is very intuitive, its precise definition is very elusive, and defining a useful metric for the shape distance between objects is a difficult endeavor. At the same time many successful ...
Physically-Based Deformations Constrained in Displacements and Volume
(Blackwell Science Ltd and the Eurographics Association, 1996)
This paper presents a method of constraining physically-based deformable objects. In this method, an object can be defined locally in terms of kinetic and dynamic (mass, position, speed), and physical parameters (compressibility, ...
Modelling Megalithic Sites
(Blackwell Science Ltd and the Eurographics Association, 1996)
In this paper, we present the MegaFormes project which deals with the modelling of megalithic sites. The goal is to enable virtual visits of megalithic sites and to help archaeologists in picturing the evolution of a ...
