Dave Seigle, President of In-Three, sent me this program to distribute to our members. It is called the Depth Machine.

Based on your screen size and resolution, it will calculate your perceived depth inside and outside the screen. When you fill in the horizontal width, don't go by the diagonal width of your monitor, go by the actual horizontal measurement.
Share your results! Does the theory translate to the 3D experience?

Neil
