XRLightProbe: reflectionchange event
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
The WebXR reflectionchange event fires each time the estimated reflection cube map changes. This happens in response to use movements through different lighting conditions or to direct changes to lighting itself. This event is not cancelable.
Syntax
Use the event name in methods like addEventListener(), or set an event handler property.
addEventListener("reflectionchange", (event) => { })
onreflectionchange = (event) => { }
Event type
Examples
Using the reflectionchange event
Whenever the reflectionchange event fires on a light probe, you can retrieve an updated cube map by calling XRWebGLBinding.getReflectionCubeMap(). This is less expensive than retrieving lighting information with every XRFrame.
const glBinding = new XRWebGLBinding(xrSession, gl);
const lightProbe = await xrSession.requestLightProbe();
let glCubeMap = glBinding.getReflectionCubeMap(lightProbe);
lightProbe.addEventListener("reflectionchange", () => {
glCubeMap = glBinding.getReflectionCubeMap(lightProbe);
});
The onreflectionchange event handler property
The reflectionchange event is also available using the onreflectionchange event handler property.
lightProbe.onreflectionchange = (event) => {
glCubeMap = glBinding.getReflectionCubeMap(lightProbe);
};
