2015.02.25 VTK now supports rendering into external OpenGL contexts with their upcoming release version 6.2. Further details can be found in this blog post. This then no longer requires the multipass rendering hack for integrating VTK with Vrui.
2014.04.12 The Appenzeller Visualization Laboratory keeps getting upgraded; this time touch capabilities were added to make some of the displays even more interactive.
Appenzeller Visualization Laboratory
The Appenzeller Visualization laboratory is housed in Joshi 278 and provides access to cutting edge visualization technology and equipment, including a traditional CAVE-type setup as well as other fully immmersive display environments.
Barco's I-space delivers visualization capabilities similar to a traditional CAVE-type configurations with four walls covering a 10 by 10 feet footprint. Active stereo glasses and optical tracking ensures a fully immersive experience P17,P18.
A rear-projection display provides a large projection surface for discussing various types of data sets. Different input modalities, including touch, allow for intuitive interaction with easy access.
Tiled display systems can provide similar capabilities compared to traditional CAVE-type displays. The fully in-house developed, custom-built DIVE (Display Infrastructure for Virtual Environments) configuration provides three walls with a 12 by 12 feet walkable footprint. The walls each consist of a 3 by 3 configuration of stereo-capable 55-inch full-HD, LED-backlit displays with only 3mm bezels. The system is driven by a traditional computer setup with one master node and three slaves driving the surrounding walls. Natural Points's Optitrack is used for optical tracking to ensure fully immersive capabilities P17,P18,P20.
In order to achieve display capabilites with higher resolution, a tiled display configuration is available consisting of 20 full-HD-capable monitors in a 5 by 4 setup driven by a single computer.
One of the disadvantage of tiled displays are typically the bezels of the individual screens creating a discontinuity within the image. By using slim bezel screens this effect can be reduced. Further, the use of higher resolution screens, in this case 4K, combined with larger sized screens can achieve even higher resolutions overall for the tiled display but with a significant reduction in distracting bezel area. This resulted in a 3 by 2 configuration of 4K screens yielding an overall resolution of 48 megapixels. The additional touch capabilities further enhance the user interface.
A mobile solution is provided by a rear-projected display system that utilizes a combination of two standard projectors with full-HD resolution. Stereoscopic capabilities are achieved with passive polarization filters and glasses combined with Kinect-based head-tracking for a low-cost solution P17,P18.
Head-mounted displays can povide a full 360-degree view as small displays with appropriate lenses mounted in front of them are placed directly in front of the user's eyes. The Appenzeller Visualization laboratory provides access to Sony's HMZ-T1 and the Oculus Rift. Combined with optical tracking or the built-in rotational tracking of the Oculus Rift a fully immersive environment can be created.
Similar to the teaching laboratory, the displays available in the Appenzeller Visualization laboratory utilize the Vrui library to drive the displays. This allows for maximal compitability between all display systems available in the research and teaching laboratories. The configurations are specifically customized to support all functionalities of each display ranging from input devices, such as game controllers or touch-based input, to tracking. Some of these configurations are custom-built specifically for the environment available, for example, touch-based input providing tablet-based input paradigms, such as pinch-zoom. Since the software environment is virtually identical to the teaching laboratory, the usage instructions apply just the same.
