I recently attended a talk by V3. Years ago they found that you get a 3D effect by taking two photos side by side (like stereo), then switching between them. They found a 4.3 Hz rate to be optimal. You can take your own photos, put them on a timeline, line up the subject of interest, loop and test.
This basic approach is harsh. Rather than switching, if you can wobble the camera position in a sine-wave motion, it's more acceptable. One problem is that much of the time, the camera position is in the middle. The next evolution was a circular motion. That gives both vertical and horizontal perspectives.
Their first prototypes moved the whole camera/lens. The latest version moves just the aperture.
I'd be curious to see this combined with stereo 3D. In the real world, we get 3D cues from stereo as well as the movement of our head/body. For instance, when we walk, we bob up and down.
Motion persistence and 3D are real. Birds with eyes on the sides of their heads lack foveal stereo vision, yet they can land on tree branches and telephone wires.
