Format
Each tile in the quilt is a conventional 2D image of a scene. The bottom-left tile of the quilt (view 0) is the leftmost view of the scene, and the top-right tile is the rightmost, like so:
Quilt File Formats
This standard may be applied to any conventional image or video file type. The most common are jpg, png, gif, mp4, mov.
File Naming Conventions
Most Looking Glass integrations output Quilts with the following naming structure:
filename_qsColumnsxRowsaAspectRatio.mp4
A quilt designed for Looking Glass Portrait with 8 columns and 6 rows would look like this:
filename_qs8x6a0.75.mp4
This allows our software like Looking Glass Studio to automatically import the quilt with the proper number of columns & rows, along with setting the proper aspect ratio. The Looking Glass Portrait has an aspect ratio of 4:3, which equates to 0.75. Looking Glass 16" & 32" systems have a 16:9 aspect ratio, which equates to a value of 1.777.
