It provides an overview of the latest developments in web based Mixed Reality including the newly released Natural Feature Tracking from awe.media (see the intro video here https://youtu.be/5_HWgrcWWts). It takes a look at developments & APIs that are currently forming. It takes a look at what is still needed and how these API gaps may be dealt with. And it explores what is currently playing out in the market and how this is likely to evolve in the near-to-midterm future.
