Vector graphics are composed of lines drawn point-to-point on a specially-driven <a href=\"http:\/\/en.wikipedia.org\/wiki\/Cathode_ray_tube\" target=\"_blank\">CRT<\/a> rather than through a <a href=\"http:\/\/en.wikipedia.org\/wiki\/Raster_graphics\" target=\"_blank\">bit-mapped<\/a> pixel graphics method on a raster scan display (like an ordinary TV set).  That may be a bit too technical for you, but the least you need to know is that vector graphics are different than usual and, in the case of the Vectrex, consisted of white lines on black backgrounds only.<\/p>\n<p>In order to spice up the system&#8217;s monochrome gameplay, each Vectrex game came with its own custom translucent colored overlay that snapped in place over the Vectrex&#8217;s built-in monitor.  The white vector lines on the monitor underneath shone through and gave the illusion of a color display for certain parts of the screen.  The one you see above is for <em>Flipper Pinball<\/em>.  Notice the different regions of the play field which have different colors to add more life and variety to the game.<\/p>\n<p>It should be noted that colored overlays were not a new idea to the Vectrex.  Their use in video games spans back to the medium&#8217;s very genesis, from the days of Ralph Baer experimenting in his lab at Sanders, and later on the first video game system ever, the Magnavox Odyssey.  Also, most early arcade games used black and white displays with colored overlays to keep production costs down, as the components needed to generate and the monitors needed to display colored graphics were expensive at the time.<\/p>\n<p>Personally, I&#8217;ve never been a fan of overlays &#8212; I find them a chintzy substitute for a true color display, and instead prefer to play my Vectrex games without them.  Monochrome ain&#8217;t so bad.<\/p>\n<p><small><em>If you use this image on your site, please support &#8220;Retro Scan of the Week&#8221; by giving us obvious credit for the original scan and entry.
