ViSTA FlowLib - A Framework for Interactive Visualization and Exploration of Unsteady Flows in Virtual Environments

M. Schirski, A. Gerndt, T. Van Reimersdahl, T. Kuhlen, P. Adomeit, O. Lang, S. Pischinger & C. Bischof
In the past a lot of work has been invested in various aspects of an interactive visualization of CFD simulation data. This includes e.g. increasing the rendering speed and responsiveness of complex visualizations, using and enhancing multimodal user interfaces, and incorporating parallel approaches for an efficient extraction of flow properties and their respective visual representation. Still, only few projects combine the significant advances in these areas. In this paper, we describe our software framework ViSTA...

Automated Testing of Virtual Reality Application Interfaces

Allen Bierbaum, Patrick Hartling & Carolina Cruz-Neira
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. It is used to ensure the correct behavior of applications. Currently, there is no common pattern for automated testing of VR application interaction. We review current software engineering practices used in testing and explore how they may be applied to the specific realm of...

A Panoramic Walkthrough System with Occlusion Culling

Lining Yang & Roger Crawfis
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 system, allowing the user to move inside the datasets on a pre-defined track and look around interactively in both the horizontal and vertical directions. The interactivity is achieved by using Image-Based Rendering ideas to pre-compute the partial renderings for the reference...

Open ActiveWrl - A Middleware Based Software Development Toolkit for Immersive VE Systems

C. Winkelholz, T. Alexander & M. Weiß
A Virtual Environment (VE) is not an application in itself. It should further be seen as a complex, multi modal human-computer interface. Immersive VE systems must be able to couple resources, most likely distributed in a cluster, into a parallel, real-time simulation. The shortcoming of most VE software libraries is the inability to provide an environment that satisfies the three main requirements in the implementation of a VE system, namely the design of the VE...

Developing Effective Navigation Techniques in Virtual 3D Environments

Sabine Volbracht & Gitta Domik
As a result of the increasing use of three-dimensional environments and of frequently inefficient possibilities for navigation, a fundamental understanding of navigation is becoming ever more important, both for users as well as for developers of three-dimensional environments. To promote this understanding a rigorous model for navigation was developed. The navigation model contains the relevant factors of influence and determines quality criteria for an efficient navigation. The model is used in a practical study. In...

Continuously-Adaptive Haptic Rendering

Jihad El-Sana & Amitabh Varshney
Haptic display with force feedback is often necessary in several virtual environments. To enable haptic rendering of large datasets we introduce Continuously-Adaptive Haptic Rendering, a novel approach to reduce the complexity of the rendered dataset. We construct a continuous, multiresolution hierarchy of the model during the pre-processing and then at run time we use high-detail representation for regions around the probe pointer and coarser representation farther away. We achieve this by using a bell-shaped filter...

Haptic Rendering Techniques for the Interactive Exploration of CFD Datasets in Virtual Environments

T. Van Reimersdahl, F. Bley, T. Kuhlen & C.H. Bischof
In pure CFD visualization tools, some flow features are hard to visualize such as the properties of a local flow probe. Haptic rendering techniques offer an intuitive understanding and allow more detailed insights than the visual perception solely. In our application framework ViSTA FlowLib for the interactive visualization and exploration of unsteady flows in virtual environments we implemented haptic rendering techniques as an add-on feature for the commonly used visualization algorithms for scalar and vector...

A Survey and Performance Analysis of Software Platforms for Interactive Cluster-Based Multi-Screen Rendering

Oliver G. Staadt, Justin Walker, Christof Nuber & Bernd Hamann
We present a survey of different software architectures designed to render on a tiled display. We provide an in-depth analysis of three selected systems, including their implementation of data distribution, sort-first rendering, and overall usability. We use various test cases to analyze the performance of these three systems.

Interacting with real time simulations - virtual reality in industry applications

A. Jönsson, J. Bathelt & G. Broman
Modern manufacturing machines are highly multidisciplinary, and with demands on short time-to-market, product development based on traditional prototype testing has become impractical. By using virtual models, it is possible to test large numbers of variants and optimise the product with the aid of a minimum of physical prototypes. Due to the immense development of software and hardware for simulation and visualisation it should today be possible also for small and medium sized enterprises to use...

CAD/CAE visualization in virtual environment for automotive industry

D. Paillot, F. Merienne & S. Thivent
In this paper we propose a method to link CAD models to an immersive environment. Since CAD models can not be directly viewed in a real-time visualization environment, we present here a complete chain of adapta-tion steps to view adapted CAD models in an immersive environment with high quality rendering. Our method allows high quality visualization of complex scenes in an immersive environment such as design reviewing for example.

3D input devices and interaction concepts for optical tracking in immersive environments

Oliver Stefani & Jörg Rauschenbach
In this poster abstract we present an interaction concept and input devices for optical tracking in virtual immersive environments. Requirements to input devices for immersive environments will be based on a document, outlining major requirements for VR-systems. A preliminary testing of the usability will be discussed. We conclude this abstract by presenting our interim findings.

Virtual Prints: Leaving trails in Virtual Environments

D. Grammenos, M. Filou, P. Papadakos & C. Stephanidis
In this paper the concept of Virtual Prints (ViPs) is introduced and alternative ways in which they can be used are suggested. The design and required functionality of a software mechanism for creating and interacting with ViPs in Virtual Environments are presented along with techniques and methods for overcoming related issues. Finally, the findings of an explorative study of the concept and pilot implementation are discussed.

Using Exercise Cycle as a Haptic Input Device in a Virtual Environment

Pasi Välkkynen, Juhani Heinilä, Sari Lainio, Sami Lakaniemi & Antti Väätänen
Virku (Virtual Fitness Centre) is a study, in which an exercise cycle is used for navigating in a virtual environment. The cycle acts as a haptic bodily user interface between the user and the simulation. The simulation takes the terrain of the virtual environment into account in order to provide better feedback of the environment for the user. We have found out in usability tests that this kind of interface enhances the user's feeling of...

An Investigation into the design of an Interface for Interaction with a Virtual Environment representing a four-dimensional object

R. Wellard & S.C. Chapman
Five methods of mapping the input from a six-degrees-of-freedom input device to the set of rotations available in four-dimensional space are evaluated with respect to how well they can be used to perform four-dimensional target aquisition tasks. Also evaluated are the user's opinions of the methods of interaction. Two of the five interaction methods perform significantly better than the rest allowing some general results to be drawn.....
