3D IMAGER

The most interesting accessory for the Vectrex was the 3-D Imager.



Literally the first in the gaming industry to have 3D, the goggles also solved the color problem with the Vectrex. Using a removeable spinning disk (each 3D game had it's own special color wheel) inserted inside the glasses, and a complicated timing mechanism, the wearer would be immersed in 3D color vector graphics. This did create one problem though - because it was a spinning disc, it created a gyroscopic effect. If you turned your head suddenly, it would often cause the disc to want to stay put and run in to the edges of the glasses.

Of interesting note, when Sega introduced their own 3-D goggles for the Sega Master System several years later, in their TV ads they initially advertised their goggles as being the first. The ad was pulled shortly after for obvious reasons.
