Micropolarized passive stereothe best combination of image quality and practicalityA micropolarizer is a thin (0.8 mm) overlay that polarizes each pixelrow in alternate directionsview of the main components of a micropolarized LCD 3D displayCS491/DES400CreativeCodingComputerScience
Micropolarized passive stereoThe micropolarizing sheet consists of rows ofalternating retarders, further separated byblack lines called guard bands, on a glasssubstrate. When the micropolarizer isregistered with the pixel grid, alternate pixelrows are polarized oppositely and are visiblein each eye.Its strengths are simple construction,compatibility with thin-bezel displays,commercial availability, and good imagequality normal to the display surface as wellas off-axis in the direction parallel to themicropolarizer lines.CS491/DES400CreativeCodingComputerScience

A fewareas next to the displaysare not covered by any camera.Right: enhanced tracking ience
Trackinginitial camera configuration had all ten cameras focused on the center ofCAVE2. This allowed for very accurate tracking within a six foot radius fromthe center of CAVE2.Since there is nearly an eleven foot radius of space within CAVE2, thetracked viewer would often walk within two feet of the displays and outsidethe trackable region. To compensate for this, we reoriented the camerassuch that two cameras are focused on one of four sides of CAVE2.This setup allows for tracking withintwo feet of the display without theneed for additional cameras,at the cost of slightly decreasedreliability at close range.CS491/DES400CreativeCodingComputerScience
TrackingVicon tracker uses the Virtual-Reality Peripheral Network (VRPN) protocolto send tracker data to an input management service.This service may aggregate data from other available input sources (likecontrollers, touch surfaces or other tracking technologies like the Kinect)before broadcasting input events to CAVE2 applications using TCP/UDPsocket communication.One of these applications is the CAVE2 System Display which shows theposition and orientation of trackable objects, the status of the controllers,and the position of virtual sound objects currently playing inside CAVE2. Thisapplication also records when trackable objects are out of the camera viewwhich is useful for calibrating the tracking camera cience
Audio system20 Genelec 6010A speakerstwo 7050B subwoofersa total of 22 separate audio channelsEach speaker is mounted at the top of each column of displays, tilted atapproximately 45 degrees toward the floor. The result is a full ring of speakersalong the top of CAVE2. The target is a hypothetical cylinder located at thecenter of CAVE2, with a diameter roughly matching the ideal viewing areafor stereo 3d, and with a height corresponding to average viewer height.The subwoofers are located just outside CAVE2, offset 90 degrees from thecenter of the visual nce
Audio system22 channels are connected to a digital-to-analog convertercontrolled by a standalone audio machine through a MADIinterface.MADI (Multichannel Audio Digital Interface) is a communicationsprotocol that allows the transmission of 64 channels of 24-bit audio ata sample rate of up to 48 kHz, via either coaxial of fiber optic cable.This protocol is particularly desirable due to the support of relativelylong cable lengths.CS491/DES400CreativeCodingComputerScience
Audio systemThe audio computer runs a custom sound server written inSupercollider, an open source programming language andenvironment for real-time audio synthesis and algorithmiccomposition.simple set of commands to interact with the CAVE2 Sound Server,which would facilitate playback and positioning of sound objects invirtual space.

Hybrid RealityFully Immersive modethe entire CAVE2 is dedicated to one virtual simulation2D modethe CAVE2 operates like a standard display wall, enabling users towork with large numbers of documents at the same timeHybrid modesome of the documents on the wall could represent immersive 3Dwindows that can be controlled with 3D user ce
Hybrid Reality SoftwareHREs uses the Omegalib middleware integrated with SAGE to assistthe development of applications on a hybrid 2D/3D system to: Support groups of observers within the system. The software allows multiple users toperceive correct or nearly correct stereo in multiple applications.Simplify application development: Classic VR development toolkits are usuallyaccessible technical users only. Users with limited programming experience shouldbe provided with a simplified development path to the system.Support a variety of visualization tools and interfaces without requiring developers toreinvent the wheel (transforms, navigation, messaging) for each one of them.Modularize interaction metaphors & technologies (navigation, selection, touchsupport, tracking, etc.), letting developers choose the most appropriate on a persystem or per-application basis.CS491/DES400CreativeCodingComputerScience
Hybrid Reality SoftwareThe Omegalib middleware stackOmegalib acts as an abstraction layerbetween the hybrid reality hardwareand user applications.At the back end, Omegalibuses Equalizer to drive the display system.Equalizer is a toolkit for scalable parallelrendering based on OpenGL.CS491/DES400CreativeCodingComputerScience
