Tennis, Anyone?

Since I have officially retired from teaching stereoscopic theory, I am aggressively looking for other things to do. I found these tennis courts right down the street, just a few blocks away from home. They are at a high school, but I was told that the public can use them.

This video has close to 1/30 (3.3%) Net Stereoscopic Deviation (NetD), which is the only amount of depth that can produce a perfectly cubic stereoscopic illusion, viewable with any horizontal field of view (from any seat).
.5% positive parallax is used to avoid eye divergence on any screen up to 40 feet wide.
The ghost-free floating window eliminates left and right edge violations.

Watch this video in 2D or 3D by clicking on the “3D” button under the video and selecting your options, e.g., “Turn off 3D”.

20 Miles Above The Earth and Mt. Wilson

20 miles above the earth, with Mt. Wilson almost directly below the camera, this stereoscopic 3D shot shows mountains starting to flatten out and the spherical earth starting to look like a round ball.
With .5% positive parallax, the depth of the screen comes almost all the way in from hundreds of miles away to the Palm Springs area, a little over 100 miles away.
Shot with Google Earth.
Very wide, unknown stereo base (interaxial).
A bit less than 1/30 net deviation (for a cubic illusion with any hFOV – from any seat in the house or theater).
.5% (1/2 of 1%) of positive parallax (beyond the screen disparity) for zero eye divergence on screens up to 40 feet wide (40 ft * .5% = 2.4 inches).
Ghost-free (on my 3D TV) pale gray-yellow solid border, skewed for your viewing pleasure. :)

What’s Your Stereoscopic Temperature?

Please sit at least 8 feet away from the screen while doing stereoscopic research. Thank you.

This is the oldest and most effective 3D trick in the book. Any flat, textured surface can be made into a perfect cubic illusion with perfectly layered depth by rotating or tilting the camera to a 45 degree angle. Be sure to end up with close to 1/30 NetD, or it won’t be a cubic illusion from any distance away.

Whenever calculating depth, reflections count. Any depth cue is simply a depth cue. This is just an illusion.

This image has no positive parallax, so feel free to reach out and grab anything you want to grab. Please put it back when you are finished.

The left and right edges of this stereo window are at two different depths. That’s legal.

Reach Up and Touch the Rotating Cube

I like to watch people try to reach up and touch the rotating cube in the Stereoscopic Depth-Analysis screening room with a 14 ft wide screen.
The cube has from 2.8% to 3.8% net deviation throughout this entire animation, which not coincidentally is the definition of the range of depth in a stereoscopic image that produces a perfectly cubic stereoscopic illusion, viewable with any horizontal field of view (from any seat).

3D Run and Gun: Can It Be Done?

I went out today and did a quick run and gun depth test with my Bloggie 3D camera, then booted it up on my 14 foot wide screen in my Stereoscopic Depth-Analysis screening room, so that nobody should have to diverge their eyes. If you get out your handy-dandy tape measure, you should see that the positive parallax never exceeds 2.5 inches on the screen.
Uncut footage, complete with the sound of air-conditioners, shot by estimating the distance from the walkway railing with my extended arm as the tool for estimating, with no other stereoscopic calculating tools used, determining that if I walk right down the center of the walkway, I should be inside my target range of 2.8% to 3.8% NetD.
I think it worked, except perhaps when I turned around halfway through the shot, and maybe at the end when I didn’t turn off the camera. Those could easily be edited out.
Easy money… not rocket science. Obviously way easier to do than most people think.
2.8% to 3.8% NetD is the only range of depth that can produce a perfectly cubic stereoscopic illusion, viewable with any horizontal field of view (from any seat).
