R5906112-06 UDX series948.8 3D projection3D setupThe projector is capable of displaying 3D images and movies in active stereoscopic 3D.Setup of a 3D installation requires an advanced understanding of 3D systems, both for the projector as well asfor the system the signal source originates from. In a 3D setup it is crucial that the projected images areperfectly synchronized through the whole signal path, from the signal source to the picture viewed through the3D goggles.Regarding setting up the proper signal source, please refer to the user manual or online help for that graphiccard. For example: when using NVIDIA Quadro cards, use the NVIDIA Control Panel to manage your 3Dsettings.8.8.1 Active Stereo & Passive StereoWhat is Passive Stereo?Passive Stereoscopic 3D (also known as “Passive Stereo”) is the standard method of creating the illusion ofdepth in an image, by means of stereopsis for binocular vision.To present stereoscopic pictures, two images are projected superimposed onto the same screen throughpolarizing filters or presented on a display with polarized filters. For Digital Cinema, a silver screen is used sothat polarization is preserved. On most passive displays every other row of pixels are polarized for one eye orthe other. This method is also known as interlacing.The viewer wears glasses which contain a pair of opposite polarizing filters. As each filter only passes lightwhich is similarly polarized and blocks the opposite polarized light, each eye only sees one of the images, andthe effect is achieved.What is Active Stereo?Field sequential 3D (also known as active 3D or “Active Stereo”) is a technique of displaying stereoscopic 3Dimages. It works by only presenting the image intended for the left eye while blocking the right eye's view, thenpresenting the right-eye image while blocking the left eye, and repeating this so rapidly that the interruptionsdo not interfere with the perceived fusion of the two images into a single 3D image.This system setup uses liquid crystal shutter glasses (also known as active shutter glasses). Each eye's glasscontains a liquid crystal layer which has the property of becoming opaque when voltage is applied, beingotherwise transparent. The glasses are controlled by a timing signal that allows the glasses to alternatelyblock one eye, and then the other, in synchronization with the refresh rate of the screen. The timingsynchronization to the video equipment may be achieved via a wired signal or via wireless communication,this by using either an infrared or radio frequency (e.g. Bluetooth, DLP link) transmitter.Projection method usedThis projector can only show active 3D images, used in combination with a 3D emitter and active shutterglasses. While it is allowed to connect passive stereo source signals, the image processing of the projectorwill convert those signals to an active 3D compatible image.The options on the projector software allow you to fine-tune the 3D settings accordingly to the specifications ofthe 3D emitter.If a 3D emitter is used that radiates IR beams, the IR beams may interfere with the IRcommunication between projector and the RCU. If such interference occurs, connect the RCU tothe projector using the remote cable. It is also advised to turn the IR receivers on the projector off toavoid the 3D emitter interference. To turn off the IR receivers, see “Remote control, on/off button”,page 23.8.8.2 Setup process 3D projectionHow to setup 3D projection?1. Connect the proper source cables to the projector. For more info, see “Connection possibilities”, page 95.2. Set up and connect your 3D emitter to the projector. For more info, refer to the user manual of your 3D emitter.GUI – Installation
