Gearbox Widget for Fine Adjustments by Hand Motion
(The Eurographics Association, 2003)
manipulation by hand is not suitable for making fine adjustments to virtual objects in an immersive environment because it is difficult to hold an unsupported hand in midair and then to release an object at a fixed point. ...
An Innovative Design Approach to Build Virtual Environment Systems
(The Eurographics Association, 2003)
A Virtual Environment (VE) presents a complex problem with interesting non-trivial challenges for software development. The majority of existing systems supporting VE are based on monolithic architectures, making maintenance ...
Color Consistency for Digital Multi-Projector Stereo Display Systems : The HEyeWall and The Digital CAVE
(The Eurographics Association, 2003)
Digital projectors have a significant advantage over CRTs for IPT setups: brightness. But they also have a number of disadvantages, one of which is color consistency. This problem is exacerbated when using the Infitec ...
Haptic Rendering of Complex Force Fields
(The Eurographics Association, 2003)
With a particular focus in scientific applications, we propose a method of haptic rendering of virtual environments which require rather complex calculations to evaluate their behaviour. Therefore it is not possible to ...
A Panoramic Walkthrough System with Occlusion Culling
(The Eurographics Association, 2003)
The interactive and high quality rendering of very complex scenes in a virtual environment is very difficult if not impossible to achieve. This research extends our previous EGVE paper that presents a panoramic walkthrough ...
A vision-based head tracking system for fully immersive displays
(The Eurographics Association, 2003)
Six-sided fully immersive projective displays present complex and novel problems for tracking systems. Existing tracking technologies typically require tracking equipment that is placed in locations or at- tached to the ...
Immersive VR Decision Training: Telling Interactive Stories Featuring Advanced Virtual Human Simulation Technologies
(The Eurographics Association, 2003)
Based on the premise of a synergy between the interactive storytelling and VR training simulation this paper treats the main issues involved in practical realization of an immersive VR decision training system supporting ...
The blue-c Distributed Scene Graph
(The Eurographics Association, 2003)
In this paper we present a distributed scene graph architecture for use in the blue-c, a novel collaborative immersive virtual environment. We extend the widely used OpenGL Performer toolkit to provide a distributed scene ...
The Virtual Showcase as a new Platform for Augmented Reality Digital Storytelling ve
(The Eurographics Association, 2003)
In this paper we discuss a case study for which we applied a customized augmented reality display - the Virtual Showcase - as a new platform for digital storytelling. Different storytelling components are identified and ...
Double Exponential Smoothing: An Alternative to Kalman Filter-Based Predictive Tracking
(The Eurographics Association, 2003)
We present novel algorithms for predictive tracking of user position and orientation based on double exponential smoothing. These algorithms, when compared against Kalman and extended Kalman filter-based predictors with ...
