When objects are made up of a set number of polygons, the computer usually has to draw them all regardless of whether the object is right up front or a mile away.
In another app, Capri snapped a three-dimension shot of an object on the table in front of us, captured its measurements and let us export that image to another device or even a 3D printer.
The peripheral utilizes three small drop down displays -- the rear is a full mirror with two half mirrors in front it, reflecting images from the phone display into what appears to be a three-dimension object -- and really, it a stunning little effect.
