Deck 15: Whats Next for Geospatial Technology

Question 1

Describe the basics of how a GeoWall system enables the user to see images in stereoscopic 3D.

Answer 1

In short,a GeoWall system has two projectors that can display the same image,just somewhat offset.The two images are passed through filters that polarize the light,which then strikes a special screen that preserves the polarized light.This then gets reflected to a viewer wearing special polarized glasses that allow one to see the items on the screen in a "3D" appearance.
