"A 3D image is orthostereoscopic when it perfectly replicates human vision. With this technique, it would be impossible to visually differentiate between the orginal scene and its representation."
"The geometry and perspective are natural, and the perceived sizes are equal to the orginal ones. As a result, the stereopsis process is much easier to view because it's totally natural. The brain does not have to guess the orginal metrics of the scene, because it is provided with them. Fusing the 3D and rebuilding the geometries are a no-brainer, and the illusion is close to perfection."

Orthostereoscopic Rig
- Create a wall and dig out a rectangle the exact size of the screen, 20 inches diagonal or 30 feet wide.
- Place two cameras at the average viewing distance, another 20 inches or 30 feet away.
- Set the interocular to the average human distance, 2.5 inches.
- Set the field of view to match the screen window in the wall.
- Converge cameras on the screen plane.
- Scale your models so that they fit in the cameras' frustums.
- Remember to stay inside the comfort zone.
