Today's Virtual Reality applications require a high degree of immersion. This may be achieved by using a CAVE incorporating powerful 3D computer graphics workstations, panoramic multiple screen displays and projection walls, stereovision and interaction ...

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 adaptation steps to view adapted CAD models in an ...

Direct manipulation by hand is easy to understand and to use for approximate positioning. However, direct manipulation by hand is not suitable for making fine adjustments to virtual objects in an immersive environment because it is difficult to hold an ...

In this paper we present the structure of the simulator which would allow diving beginners to experience the effect of buoyancy control mechanisms before actually entering the water. We believe such training would be less stressful and safer for all ...

As one of the final steps in the industrial manufacturing chain, machining operations require significant economic consideration. At this stage, design components have already passed through several steps of this value-added manufacturing process. ...

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 ...

There are many classes of information for which a suitable 3-D representation does not (yet) exist, and for which users are familiar with more or less ef cient desktop interfaces. Therefore, a convenient way of accessing GUI-based systems from within a ...

This paper presents a non-parametric full-gamut color matching algorithm. Color matching is important for the seamless appearance of tiled displays. In particular we address the case where the tiled display is composed of different types of projectors ...

The working volume of a Mixed Reality (MR) system - which superimposes the real environment with computer-generated virtual content - strongly depends upon the output/display device used. Single screen projection systems like the Barco Baron Table or ...

We describe a new technique to display seamless images using overlapping projectors on curved surfaces. Our method addresses issues such as automatic registration, smooth intensity blending and efficient rendering. Previous techniques for automatically ...

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 present a simple yet efficient calibration and registration procedure for improving the overall static display accuracy of the Visual Haptic Workbench. The procedure is used for precisely colocating the visual and haptic workspaces of the system and ...

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 ...

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 on a specially designed and ...

We present an affordable optical head tracking system for desktop-like VR/AR environments. The generic and specific head tracking requirements for these type of environments are de ned, as well as the relaxations such environments put on head tracking ...

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. The key idea is to define a ...

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 derivative free measurement ...

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 how predictors work across ...

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 attached to the user in a way that is suitable for ...

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 ...
