Hello everyone, I’m Kyle Appelgate, and I wrote the HoloPlay Unity SDK. I’m regularly working with the rest of the team to add new features to the SDK, and I want to talk about an exciting addition that will be ready by the time Looking Glasses ship out to all you backers: Mosaic Mode!
Everywhere I go, people are always saying to me: “I love the Looking Glass, but can it be bigger?” Until now, I’ve always had to say no. The two models we currently offer are made with the 3D creator in mind: either the Standard or Large Looking Glass will fit comfortably on your desk as a welcome addition to your existing workspace. But even so, many of the people I’ve talked to already have grand plans for what they would do with an extra-extra-extra-large Looking Glass.
Fortunately for those big dreamers amongst you, you now have the option of tiling Looking Glass units together!
Admittedly, this idea was not mine, and I was skeptical when it was first proposed. We had learned a lot about what did and didn’t break the illusion of a virtual scene being perceived as truly three-dimensional and viscerally real over years of making a variety of volumetric and lightfield displays, and I was sure the effect we'd achieved in single Looking Glasses would not survive the gaps that we would be introducing between the systems in an array. But as I’ve learned repeatedly in working with these sorts of things: you don’t know until you try it. So, thankfully, I was persuaded into doing just that.
To my surprise and delight, it worked! There were some snags I ran into with my setup that seem obvious in retrospect. For example, most newer graphics cards capable of 4+ outputs consist mostly of DisplayPort ports, and most DisplayPort-to-HDMI cables we had in the lab at the time were of the variety that max out at 1080p, which are insufficient for either model of Looking Glass. If you’re planning on using mosaic mode with your Looking Glasses, save yourself the trouble I had and make sure you use cables or adapters that are rated for 4k at 60hz.
It's interesting how effectively the 3D illusion achieved in a single Looking Glass still comes across in this tiled format. Tiling works well even with the Large Looking Glass!
Enjoy, and I look forward to seeing what extra-extra-extra large creations you all dream up!
