Automation and Ethernet Combine for 3D Disney Attraction
Toy Story Midway Mania debuts Disney's extensive use of automation and controls over Ethernet.

snippet:

“Every screen in the attraction has a Hewlett-Packard game computer that receives data from the wayside computer,” Gerstner says. “At that point, mathematics takes over. An algorithm takes all encoder values and calculates a position on the screen where the projectile should emanate from the gun that the guest is pointing and firing. It even calculates for the arc of the gun. A computer-generated image is then created and sent via fiber link to the projector and to the 3D active polarizer to produce the image and project it on the screen.”

An image for the left eye and the right eye is produced by the game computers. Screen polarization synchronizes images sent from the computers so that a 3D image is rendered and perceived by the guest in 3D thanks to the special glasses we’re all familiar with from viewing 3D movies.
