Search Space Reduction in Optical Tracking
(The Eurographics Association, 2003)In this paper we present a practical method for reducing the space when searching for point patterns in optically tracked virtual reality applications. The method uses a predictor to estimate the future position of a point. ... -
PHANToM Haptic Device Implemented in a Projection Screen Virtual Environment
(The Eurographics Association, 2003)This research combines the PHANToM 1.5 haptic device with a six-sided projection screen virtual environment in order to explore the benefits haptic devices bring to this type of immersive environment. The PHANToM is placed ... -
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 ... -
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 ... -
A Testbed for Studying and Choosing Predictive Tracking Algorithms in Virtual Environments
(The Eurographics Association, 2003)We present a testbed for comparing predictive tracking algorithms that allows virtual environment system developers to make better choices about which predictors to use in their environments and aids researchers in determining ... -
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 ... -
Fast Approximate Visible Set Determination for Point Sample Clouds
(The Eurographics Association, 2003)We present a fast, efficient method to determine approximate visible sets for vegetation rendered as point sample clouds. A hardware accelerated preprocessing step is used to determine exact visibility for a selected set ... -
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 ... -
Immersive Sound Field Simulation in Multi-screen Projection Displays
(The Eurographics Association, 2003)This paper describes the immersive sound field simulation technology that represents an interactive sound field in the multi-screen projection display. In this method, convolution filters, that were calculated based on the ... -
Detecting Dynamic Occlusion in front of Static Backgrounds for AR Scenes
(The Eurographics Association, 2003)Correctly finding and handling occlusion between virtual and real objects in an Augmented Reality scene is essential for achieving visual realism. Here, we present an approach for detecting occlusion of virtual parts of ... -
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 Metaverse - A networked collection of inexpensive, self-configuring, immersive environments
(The Eurographics Association, 2003)Immersive projection-based display environments have been growing steadily in popularity. However, these systems have, for the most part, been confined to laboratories or other special-purpose uses and have had relatively ... -
Automated Testing of Virtual Reality Application Interfaces
(The Eurographics Association, 2003)We describe a technique for supporting testing of the interaction aspect of virtual reality (VR) applications. Testing is a fundamental development practice that forms the basis of many software engineering methodologies. ... -
