Introduction
What WebXR Environment is, what it owns and what it leaves to the app, in plain terms.
Getting started
Install an adapter, create the director, apply a preset and tick it from your render loop.
The environment document
The five slots an environment carries, how partial specs inherit, and the one interpolation rule.
Presets and transitions
Naming and registering presets, easing, transition timing, and how passthrough and light estimation layer over the slots.
Audio
The cue registry, buses and master gain, retrigger policy, attenuation, cones, and knowing when a sound finished.
Roadmap
What is experimental, what is pending, what has been asked of sibling packages, and what is not planned.
