Rear Tiled Display

Tiled displays are an emerging technology for constructing semi-immersive visualization environments capable of presenting high-resolution images from scientific simulation.

Image blending, alignment, and calibration are the key major technical challenges to producing practical tiled display systems . The goal of a high-resolution scalable display surface demands that we address the issues of how to transform a collection of separate tiles into one seamless display. Tiled display technologies offer a range of opportunities for exploring scalable, high-resolution, large-format displays, for applications ranging from smart information murals to collaboration walls to high-resolution scientific visualization. Significant progress has been made in understanding the technological challenges relating to screens, projectors, distributed graphics environments, and integration into seamless systems.

3D TV Sony Bravia 46"

There are several techniques to produce and display 3D moving pictures. The basic requirement is to display offset images that are filtered separately to the left and right eye. Two strategies have been used to accomplish this: have the viewer wear eyeglasses to filter the separate offset images to each eye, or have the lightsource split the images directionally into the viewer's eyes (no glasses required).

3D-ready TV sets are those that can operate in 3D mode (in addition to regular 2D mode), in conjunction with a set-top-box and LCD shutter glasses, where the TV tells the glasses which eye should see the image being exhibited at the moment, creating a stereoscopic image. These TV sets usually support HDMI 1.4 and (if an LED-backlit LCD Television) a minimum (input and output) refresh rate of 120 Hz; glasses may be sold separately.

Rear Passive 3D Stereo

The most common passive stereographic system uses dual projectors with polaroid filters in front of the projectors and matching filters in the glasses. The projectors can driven in many ways, by a single computer with a multiple graphics pipes, by semi independent but synced computers, synced DVD players, slide projectors, etc. This solves the main problems identified above with active systems. If the system is being driven by computer then one can use non stereo capable hardware from which there is a wide choice from the consumer game industry. There is a wider source of suitable projectors, although now one needs two of them. Lastly but critical for public environments, the glasses cost a couple of dollars instead of hundreds. Our solution is composed with 2 Barco Projectors iQ R350 with a resolution at 1440x768 and a rear projection panel 2,50x2,10 mt of dimension.

Rear Projection WorkBanch

We built our environment on a custom-made interactive workbench with a rear projection system based on an Epson with short lens. The interaction is done with a multitouch display system 32-touches from PQ Labs.

Head Mounted Display

A head-mounted display or helmet mounted display, both abbreviated HMD, is a display device, worn on the head or as part of a helmet, that has a small display optic in front of one (monocular HMD) or each eye (binocular HMD).

A typical HMD has either one or two small displays with lenses and semi-transparent mirrors embedded in a helmet, eye-glasses (also known as data glasses) or visor. The display units are miniaturised and may include CRT, LCDs, Liquid crystal on silicon (LCos), or OLED. Some vendors employ multiple micro-displays to increase total resolution and field of view.

Major HMD applications include military, governmental (fire, police, etc.) and civilian/commercial (medicine, video gaming, sports, etc.).

Quadro Plex 2200 D2

Quadro Plex 2200 D2 systems provide flexibility to create environments based on a wide range of needs - from a single 4K display or projector to an eight display configuration.

Featuring NVIDIA® SLI® Mosaic technology, Quadro Plex scalable visualization solutions allow both the operating system and any professional application to transparently scale across multiple displays or projectors, and drive immersive stereoscopic 3D environments.

Providing advanced interactivity and realism of the most demanding applications and data sets, each Quadro Plex system features dual Quadro FX 5800 GPUs and a combined 8 GB of graphics memory. Scale performance even further by connecting two Quadro Plex systems, with a total 16 GB of memory, to a single workstation.
