Improving 3-D Spatial Visualization Skills with Multimedia Software
(Eurographics Association, 1999)
Development and evaluation of 3-D spatial visualization skills is discussed. Strategies for improving spatial skills are presented and multimedia software being developed by the authors is described. Initial assessment ...
Interfacing Cultural Heritage
(Eurographics Association, 1999)
In this paper we describe briefly intuitive physical interface called “Virtual Balance”, present recent modifications and give the most impressive example of its use for navigation in and exploration of reconstructed models ...
Head-Tracked Stereo Viewing with Two-Handed 3 D Interaction for Animated Character Construction
(Blackwell Science Ltd and the Eurographics Association, 1996)
In this paper, we demonstrate how a new interactive 3 D desktop metaphor based on two-handed 3 D direct manipulation registered with head-tracked stereo viewing can be applied to the task of constructing animated characters. ...
Computation of Higher Order Illumination with a Non-Deterministic Approach
(Blackwell Science Ltd and the Eurographics Association, 1996)
In spite of the number of efforts made by the computer graphics researchers, till today the computation of view-independent global illumination in an environment containing non-diffusely reflecting objects is a non-resolved ...
Extracting contour lines from a hierarchical surface model
(Blackwell Science Ltd and the Eurographics Association, 1993)
The Hierarchical Triangulated Irregular Network (HTIN) is a structure for representing 2?-dimensional surfaces at different levels of detail through piecewise-linear approximations based on triangulations of the surface ...
GKS-9x: The Design Output Primitive, an Approach to a Specification.
(Blackwell Science Ltd and the Eurographics Association, 1994)
This paper describes an approach to the formal definition of the design primitive introduced in the revision of the ISO/IEC computer graphics standard, GKS. The paper starts with a general description of the design primitive ...
Reasoning About Gestural Interaction
(Blackwell Science Ltd and the Eurographics Association, 1995)
Many of the reported developments in the design of virtual spaces or visualisation systems are based on improvements in technology, either physical devices or algorithms for achieving realistic renderings within real-time ...
A Paradigm for the Robust Design of Algorithms for Geometric Modeling
(Blackwell Science Ltd and the Eurographics Association, 1994)
Geometric modelers are becoming faster and more powerful, but they still suffer from reliability problems because of floating point errors. Previous work in the field of robust geometric modeling tends to be problem specific ...
Virtual lights: a method for expressive visualization
(Eurographics Association, 1999)
There has been great interest in expressive visualization over the last few years. This kind of visualization is used in 2D animation, illustration, and schematic drawing. The flat shading and shape lines, which we call ...
Pandora: An Experiment in Distributed Multimedia
(Blackwell Science Ltd and the Eurographics Association, 1992)
An experimental workstation is described which supports digital video and audio in a distributed environment, and which presents this functionality to the user through the medium of a video-extended implementation of the ...
