XRLightProbe: reflectionchange event

The WebXR reflectionchange event is passed to an XRLightProbe 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.

Examples

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);
});
