A 3D optical illusion of sorts is making YouTubers lose their brains.

YouTube science guy Tom Scott claims his&nbspnewest video can be seen in 2D and 3D simultaneously, though it wasn&#8217t shot with any special equipment. What type of dark magic is that this? Well, as Scott explains, everything comes lower towards the Pulfrich effect, or perhaps a mental interpretation where your vision see motion as getting depth as a result of delay processing more dark images from lighter ones.

Obvious as dirt, right? It will likely be when you check it out yourself.

To see the clip in &#82203D,&#8221 just cover your right eye with dark shades and examine it having a fast, stable connection inside a vibrant room (Note: it really works far better on the laptop than the usual smartphone, along with a slower connection may&nbspcause the frame rate to&nbspdrop, nullifying the result.).

Since your right eye sees a more dark image, the signal it transmits for your brain is going to be delayed by around one frame. Caused by that delay is you finish up perceiving two distinct images, one out of your left eye and something out of your right. The ultimate component is motion. When the camera is stationary, both images would sit on the top of one another as well as your eyes wouldn&#8217t be aware of difference. However, when the camera starts panning, it&#8217s just like you&#8217re seeing two images from two cameras which are filming alongside one another. It won&#8217t seem like Avatar, however it works surprisingly well.

Modern 3D differs since it&#8217s produced by projecting two separate videos onto a screen and&nbspcombining all of them with filters (generally, individuals goofy 3D polarized glasses). As Scott highlights, his method has been utilized around the giant screen previously, as with the 1993 Physician Who episode &#8220Dimensions over time,&#8221 but isn&#8217t simple for everyday uses.

However, for viral YouTube videos, this fascinating approach to simulating 3D is indeed a jewel.
