What is 3D Preview and how do I take 3D screenshots of my app?

3D preview is a quilt image to be shown in the Looking Glass when you hover on the app before you actually launch the content. It must be a 4 x 8 quilt image, ideally 2048 x 2048px. Easiest way to take a screenshot is using the screenshot function in the HoloPlay SDK by pressing F10 in Unity editor or builds to save 3D screenshot to the root directory. Alternatively, you can use the Lightfield Photo App by Looking Glass to generate a quilt from photosets.

What is a quilt?

The quilt is the format Looking Glass uses to store light fields in sets of views as common 2D images. Views start in the lower left corner, with view 0 being the leftmost view. The views are then added to the right and then up, in a grid, like so:
