Hyper Hollywood

If the screen (zero parallax) is located about 13 feet in front of the camera in this shot (http://youtu.be/dLyBiK5XRjM), and about 40 feet in front of the camera in this shot (http://youtu.be/noNc4cRvuKY), then where is it located in this very hyper shot?

Horizontally post-panned stereoscopic 3D shot of the Hollywood sign and surrounding area.
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. :)

New Google+ White Space Causing Neckache

The new Google+ layout with all the white space is giving me a neckache. I hope you will understand why, when you watch this video.

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”. If you are using red/cyan anaglyph glasses, be sure to select “Red/Cyan” then “Optimized (Dubois)”.

Back To Rehab, Again

It looks like it’s back to rehab time again in the stereoscopic world, and by far the best thing that I recommend to everyone is to grab a cube, somewhere (anywhere), give it exactly 1/30 net deviation, remove the back and the front, then composite it around some images or videos. This will force every image to have exactly 1/30 net deviation, and you can discover some amazing truths about stereoscopic depth. There is no shortage of perfect cubes in the real world, and in the CG world via Google SketchUp freeware or Blender (SketchUp the easier of the two to use).
Have fun! :)

Back From The Dead

I guess I probably should bring my WordPress blog at RogerMaddy.com back from the dead.
I have been spending most of my time working with stereoscopic 3D again lately, and although I enjoy talking about it, I get burned out repeating the same things over and over, so a blog is a great place to document stuff, so I can refer back to specific topics, demos and posts.
For the past few months, I have been using Google+ as my primary means of communication, and although I am very happy with it, it isn’t a perfect solution.
So here we go (again). Cross your fingers… :)

Cinematography 3D List and “The Round Earth Society”

Yo. Peeps.
What’s going on over in the Cinematography 3D List? Anybody figuring out what the old “1/30 Stereo Base Rule” was all about?
Surely, eventually, somebody has got to figure it out… LOL.

I probably should start a stereo 3D forum called “The Round Earth Society”… where 1.2mm of 36mm is still practiced (3.3% or 1/30)… after all these years. LOL.
It’s all bout the deviation………. yup……….. always has been and and always will be.
Stereography isn’t trigonometry or rocket science. It’s just one simple formula: 1/30 (3.3%) Net Deviation.
2.5% is too flat. 4% is too deep.
3D is just an optical illusion with almost nothing in common with “reality”. The only real trick is to get everything to look perfectly round. Like the Round Earth. That is why one single number and only one number is the “key”, and that number is 1/30 (3.3%).
And the best thing is Roger Ebert won’t get those 3D headaches if you do that… LOL.

Thanks,
Roger Maddy
