Graphics displays Vector vs. raster display CRT monitor Flat panel displays 3D displays Frame buffer True and index color CRT color displays Different colors are

obtained by use of different phosphor coatings Refreshing CRT image must be refreshed Typically more than 60 times per second (60

Hz) In each refresh interval, the entire image from frame buffer is sent to the display surface Liquid crystal display (LCD) Non-emissive, reflective or requires back light (flurescent or LED)

Stereo View Depth cues are diverse (e.g., focus, color, movement parallax) Stereo view: slightly different left-eye and right-eye views (parallax)

Problems: - How to generate different these views, - How to separate them. View separation Several techniques for separating left and right images - color (anaglyph images) - polarization (3d movies) - shutter glasses (most 3D displays)

- autostereoscopy (viewer(s) in well defined spot(s) - parallax barrier (e.g. Sharp 3D LCD) - lenticular lenses (array of magnifying lenses, e.g. Toshiba 3D TV) LCD 3D glasses Displays: Head mounted display Wireless glass for filtering left/right images

v Single viewer image (left/right) per frame v 2 View may depend on the position

of the head (movement parallax) 120Hz display: 60 Hz for refreshing left/right image
