has announced an update to its ARCore platform for augmented reality. The platform gains a handful of new tools to help developers create more immersive and shared AR experiences. First and foremost, ARCore introduces something Google calls Cloud Anchors. With Cloud Anchors, multiple devices can generate a shared, synchronized image of the world. It allows multiple phones to see and interact with the same content in the same place at the same time. It's a way to enable multi-player games, for example, or group room decorating. Sceneform is another new tool that makes it easier for developers to make AR experiences from Java-based applications. Sceneform has an expressive API, renderer, and seamless support for 3D objects. Last, Augmented Images makes it possible to attach augmented reality content to objects in the real world and expand them to view 3D renderings, such as opening a box. This is made possible in pat thanks to new support for vertical plane detection. The new ARCore will be made available to both Android and iOS devices. Developers can grab the new ARCore developer tools from the Android Developer web site.
