By default, apps launch into the Shared Space, where they exist side by side \u2014 much like multiple apps on a Mac desktop. Apps can use windows and volumes to show content, and the user can reposition these elements wherever they like. For a more immersive experience, an app can open a dedicated Full Space where only that app\u2019s content will appear. Inside a Full Space, an app can use windows and volumes, create unbounded 3D content, open a portal to a different world, or even fully immerse people in an environment.<\/p>\n<\/blockquote>\n

Questions remain around how effective such ports will ultimately be in a three-dimensional plane or \u201cinfinite canvas\u201d \u2014 borrowing a phrase from comics scholar Scott McCloud. To ease the growing pains even further, the company will begin opening \u201cdeveloper labs\u201d in a variety of cities next month, including Cupertino, London, Munich, Shanghai, Singapore and Tokyo.<\/p>\n

That\u2019s designed, in part, to address one of the biggest pain points at the moment: getting an extremely expensive and unreleased headset in front of developers. Teams will be able to test their app on the hardware at the site, or apply for hardware developer kits to test outside of the official locations.<\/p>\n

In addition to existing developer tools, Apple is introducing Reality Composer Pro. The Xcode feature makes it easier to preview 3D models, images, sounds and animation on the headset. There\u2019s a simulator, as well, which offers a virtual approximation without the actual hardware. Unity development tools will be added to the mix starting next month. That\u2019s good news, as gaming experiences were conspicuously missing from the original presentation.<\/p>\n
