  Center for Advanced Visualization and Interaction - CAVI  
    Lab facilities  
   
   

In CAVI the activities in the lab focus on visualization and interaction with 3D models.

The use of the different facilities in the center can be combined so that a model can be visualized in various ways and levels depending on the need. One and the same model can be visualized in a high resolution 3D panorama, subsequently saved as a 3D model on a CD ROM, or used as the 3D scenography in the virtual studio be used for professional video recording of the model in a realistic computer generated environment.

Panorama

The Panorama cinema is a cylinder shaped screen placed in a room that seats approximately 15-20 persons. The size and shape of the screen mean that the visual angle of the spectators is almost covered by the screen.

Models are displayed in active stereo, i.e. a picture for the right and the left eye is displayed alternatively in a very high frequency. Without shutter glasses the spectator experiences the image as blurred. But with shutter glasses that alternate between closing off for the right and the left eye in the same frequency, the spectator experiences an illusion of 3 dimensional depth.

The Panorama is particularly suited for displaying large-scale models within the domains of architecture and city planning.

Holobench

The Holobench is a combination of two 180x110 cm sized projection screens placed at right angles to each other in an L shape.

Also here it is possible to show models in active stereo, i.e. the pictures on the screen draw a picture for the right and the left eye alternatively in a very high frequency. Without shutter glasses the spectator experiences the image as blurred. But with shutter glasses that alternate between closing off for the right and the left eye in the same frequency, the spectator experiences an illusion of 3 dimensional depths.

A tracking system allows the spectator's gaze to be responded to through movement of the model and this heightens the impression of an object in front of the spectator's eyes.

Virtual studio

The virtual studio or virtual stage set makes it possible to use digital 3D models as sets instead of scenography made from wood, steel, cardboard or other materials. Live recordings in a blue studio with real objects can be mixed with computerised models. It is, for example, possible for a studio host to walk into a completely blue room, sit down on a primitive wooden box and start reporting. What one sees on the television screen could then be that the host enters from a doorway, passes behind a row of plants to sit down at a speaker's desk to start reporting.

Performance lab

The performance lab is an open space and a facility for several types of experiments including experiments using a reactive performance space, which is a theatrical environment that enables physical actions to effect and manipulate electronic media. These spaces allow performers to improvise with media through a variety of means.

Electronic media consists of any media that can be controlled from a computer. These are generally divided into four categories: visuals, light, sound and mechanical systems. Physical actions within the space consist of anything that can be sensed and interpreted by a computer. This consists of things like video based sensing, tracking systems, sound sampling, pitch detection or analogue sensors (heat, touch, bend, acceleration, etc).

CAVI has a motion capture equipment as part of the laboratory. Motion capture is a technology that makes it possible to register the movements of a person and use the data to animate a digitally created figure. Cartoonists use motion capture equipment to animate their characters. The technology is also used in many other areas for example in the study of movement in dance, sport and medical research.
