  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Here is an example of stereoscopic adapter AKA "beam splitter". 63mm base and convergence adjustable for target screens from 22 inch to IMAX size.

What is Ralistic 3D AKA "Ortho"?

It is real World scene projected on a screen with view angle which matches the 63mm IO stereoscopic camera the real World scene was captured by.

Did you know that no Hollywood movie producer had ever created Realistic 3D content.

Cinema size screen can project Realistic 3D content only if floating window technique is used.

For most of the home theater viewers a +0.4 to +1 diopter correction glasses are required to bring infinity focus to the surface of the home theater screen.

Most if not all 3D titles ever produced project miniaturized on home theater screens.

Most of the 3D titles ever produced are completely distorted by unmatched view angle and IO of the camera used.

The worst 3D movie ever produced has variable IO during a single take which make the scene and actors grow or shrink unintentionally, killing the realism completely (see AVATAR).

Unmatched view angle compresses or expands depth of 3D content making any 3D objects which are rotated or translated look like a morphing blob of jell.

No movie director has full understanding of human stereoscopic vision.

Most of the stereographers had not seen Realistic 3D content.

Most if not all consumers had never seen Realistic 3D content.

Become the first creator of Realistic 3D content and resurrect the 3D business.

The effect of Realistic 3D immersion is unmatched and for some viewer can only be described as visiting another world.

Shooting Realistic 3D content is extremely simple, enjoyable and rewarding.

Here are the simple rules:

1. Compile the minimum required stereoscopic equipment: stereoscopic camera with 63mm fixed IO and fixed 35mm FL per eye, stereoscopic view finder with home theater size screen preset convergence
and camera transport with vibration damping and 3D translation and horizontal only rotation.

2. Treat the camera as the prospective viewer's head thus make sure that you never move the camera faster than a viewer can movie his or her head.

3. Let the scene and its actors play the plot and do not use any of the known camera FX most of all never use the zoom as human eyes have no capability of such optical action.

4. If you choose the most comfortable home theater screen size (50 to 150 inch diag.) and most comfortable viewer seating position, your stereoscopic window will never run into the ground,
siling and or side objects, thus preventing stereo window violations.

5. Screen your Realistic 3D content on the target screen which matches the camera's stereoscopic window size and make sure that no obvious distortion and or window violations are present.

6. Since at the moment the only missing pierce of the Realistic 3D viewing equipment are the +0.4 to +1 diopter glasses make sure the your prospective viewer gets a pair which feats inside his regular 3D viewer goggles.

7. Make sure that all prospective viewers know the requirements and limitations of projecting Realistic 3D content by providing example videos and written info.


Following those rules you cannot go wrong and your Realistic 3D content will be timeless and enjoyable for generations to come.

Good lack and have fan creating Realistic 3D content...

Very Intriguing.
- Do you have a still grab of actual footage you have shot?
- are you making this commercially available?
- What would it take for us to get our hands on this for testing.

thanks,

I just did the crossed eye thing, and got the effect right away, it doesn't hurt my eyes at all, and the effect is very realistic. Are those Red camera stills?

So if this is single camera, are you recording two images side-by-side on the same sensor, thus splitting the resolution in half?

Yes, the RED Epic camera sensor has enough resolution to accommodate two 16:9 full HD frames side by side.
 
Yeah I did the cross eye thing too as I always do on set, can't never get a better faster 3D view in any other way, unless using 3D glasses, but still the only way to check your 3D space and dimensionality right on the spot with your two images side by side... ;)


Funny how the images of the country road alone toked longer to open up in center, while the other 3 open right up... ;)


An interesting concept indeed.

And the DRAGON at 6k even more so... ;)

Hello Maciej,

looks interesting!

any progress on this? did you build this yourself?

best,
Joost

Yes, I am now building stereoscopic view finder adapter with horizontal image flip since the lens adapter flips the image horizontally.
Convergence and focus adjustment will allow for real time 3D preview regardless of light condition.
Both adapters in a rig should add no more than 1kg of weight.
 
paulherrin said:
you can also do a horizontal flip digitally... no?

Yes, but such configuration requires very complex off-axis ocular lenses for convergence or stereo window size adjustment.
Much better quality of preview is obtained simply by two mirrors with adjustable angle and it only requires simple ocular lenses for focusing and view angle matching.

I have a question...isn't this assuming the interocular distance is standard at 63mm? E.g., in adults the value might vary between 54-68mm and for kids it might vary between 41-55mm.

From Wikipedia:
  • The typical pupillary distance for adults is around 54–68 mm, while measurements generally fall between 48 and 73 mm.
  • For children the measurement usually ranges from 41 to 55 mm.
  • The 95 percentile adult male in the USA has an IPD of 70 mm (2.8 in) and the 5 percentile, 55 mm (2.17 in). Those are each the 5% of USA men at the far range and short range, respectively.
  • For adult females in the USA the figures are 65 and 53 mm (2.6 and 2.1 in).
  • For Europeans the figures are 1 mm smaller than the above.

If this is the case, can anyone achieve true orthographic 3D?
 
63 mm is the human average IO distance. Ortographic 3D is created using ortographic camera or a camera with FL of infinite length.
Realistic 3D projects undistorted perspective image of real world scene and a scene is perceived in its original scale.

Here is an example of ortographic 3D image:

Interesting - I see you have 2 3d adapters for Epic - what is the difference between them.

Realistic has 63mm stereo base and the classic one has 140 mm base which creates miniaturized scenes (best for group of people/sporting events).
