Slippery circles: Vuforia, Tee Shirts, and computers being picky.
Recently, I was tasked with producing a graphic for a shirt that would be visible with Vuforia, and have an augmented reality game overlayed on top of it. This is all fine and good, except the logo that I made for my company earlier looks like this. Glimmer Technologies in some of its splendor. So this image tracks well when evaluated by the Vuforia algorithm. From one to five, it's a four. It does this by making a greyscale image and finding unique contrast points in the image like so. Now, this presents some issues for a teeshirt. We were getting these shirts screen printed which means they have to lay down one color at a time. Moreover, screens cannot print in a gradient, unless that gradient is produced in halftones. This is a crappy quality image of the awesome work that Threadbare did printing our logo. They had to send our logo to a guy to make a color separation, which then could be fed into their machines which can make halftoned screens of each color.
