The getReflectionCubeMap() method of the XRWebGLBinding interface returns a WebGLTexture object containing a reflection cube map texture.
The texture format is specified by the session's reflectionFormat. See the options parameter on XRSession.requestLightProbe() and XRSession.preferredReflectionFormat for more details. By default, the srgba8 format is used. When using a rgba16f format, you need to be within a WebGL 2.0 context or enable the OES_texture_half_float extension within WebGL 1.0 contexts.
getReflectionCubeMap(lightProbe)
A WebGLTexture object.
You typically call getReflectionCubeMap() whenever the reflectionchange event fires on a light probe to retrieve an updated cube map. This is less expensive than retrieving lighting information with every XRFrame.
If the rgba16f format is used, enable the OES_texture_half_float extension within WebGL 1.0 contexts.
const glBinding = new XRWebGLBinding(xrSession, gl);
gl.getExtension("OES_texture_half_float"); // if rgba16f is the preferredReflectionFormat
xrSession.requestLightProbe().then((lightProbe) => {
lightProbe.addEventListener("reflectionchange", () => {
glBinding.getReflectionCubeMap(lightProbe);
});
});
