3D viewing with 2 images

How do I incorporate to images into one object for viewing on the Gear VR from Unity? I have some renders that are rendered out with side by side stereoscopic (lets say 500 pixels high and 100 pixels wide, each eye would see a 500x500 pixel square image then) and have a lot of 3DsMax and Maya knowledge, but with Unity I don't know how I would code this to appear 3D in the Gear VR goggeles if I have one map, that is side by side on a plane or something? I'm assuming, it would be coded to say in left left use the uvw at x,y coordinates, and with right eye move uvw coordinates to the right 500 pixels? But how?
