Surface Reconstruction from Unstructured 3D Data
(Blackwell Science Ltd and the Eurographics Association, 1996)
Building 3 0 models from unstructured data is a problem that arises increasingly as new 30 scanning technology is able to produce large and complex databases of full 3 0 information. Huge efforts put into segmenting entire ...
Virtual Dunhuang Art Cave: A Cave within a CAVE
(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 ...
The Layout Design Language: A Technique for Generating Layout Plans
(Blackwell Science Ltd and the Eurographics Association, 1996)
The work described in this paper arose from a requirement for a system to support the production of models for training simulator visual systems and other visualisation applications. To reduce the labour involved in ...
Stochastic Iteration for Non-diffuse Global Illumination
(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 ...
Accelerated Evaluation of Box Splines via a Parallel Inverse FFT
(Blackwell Science Ltd and the Eurographics Association, 1996)
Box splines are a multivariate extension of uniform univariate B-splines. Direct evaluation of a box spline basis function can he difficult but they have a relatively simple Fourier transform and can therefore be evaluated ...
Scripting Interactive Physically-Based Motions with Relative Paths and Synchronization
(Blackwell Science Ltd and the Eurographics Association, 1996)
This paper presents a novel approach for facilitating the use of physically based models by animators. The idea is to let the user guide motion at a high level of control by giving approximate desired trajectories and ...
ANIMA: An Interactive Tool for Scientific Data Animation
(Blackwell Science Ltd and the Eurographics Association, 1993)
This paper describes an animation interactive system that produces image sequences used to study the numerical results of scientific simulations. The fundamental goal of the system is to provide an easy method for observing ...
A Fractal Method for Digital Elevation Model Construction and its Application to a Mountain Region
(Blackwell Science Ltd and the Eurographics Association, 1993)
This paper presents and discusses the results of a methodology for the construction of Digital Elevation Models (DEM), based on mathematical principles of fractal geometry. Classical approaches to DEM are founded on numerical ...
Graphic Objects: A Mathematical Abstract Model for Computer Graphics
(Blackwell Science Ltd and the Eurographics Association, 1993)
This paper defines an abstract mathematical model for graphic systems which incorporates modelling operations. The model is based on the"graphic object" concept. A graphic object is an abstraction of a graphic entity. ...
Efficient Hierarchical Refinement and Clustering for Radiosity in Complex Environments
(Blackwell Science Ltd and the Eurographics Association, 1996)
Generating accurate radiosity solutions of very complex environments is a time-consuming problem. We present a rapid hierarchical algorithm that enables such solutions to be computed quickly and efficiently. Firstly, a new ...
