Radiant Star, the company that made the 3Dfier 2D to 3D converting DirectShow filter, is now preparing a new interesting product called 3Dfier Viewer. It is a simple and affordable accessory that should allow you to watch stereoscopic 3D photos and videos in 3D on your Apple iPhone 4/4S or iPod Touch 4th generation (although it might work well with other mobile devices as well). The 3Dfier Viewer is essentially a cardboard box with two sets of different lenses and open sides, foldable and lightweight for easy transportation, so what you do is essentially put the device inside and watch the screen through the lenses holding the 3Dfier Viewer close to your eyes. It has two functions to allow you to watch stereoscopic 3D content displayed in Side by Side format on the display of your Apple mobile device (the dual lens side) or to magnify the image displayed on the screen of the mobile device (apparently also separating colors in different planes creating somewhat of depth feeling). The device sounds quite promising, especially considering the fact that the suggested retail price of the 3Dfier Viewer should be less than $10, and of course I’ll be trying these adapters as I just got some for testing, so expect some feedback very soon.
