VRDisplay: exitPresent() method
Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
The exitPresent()
method of the VRDisplay
interface stops the VRDisplay
presenting a scene.
Syntax
Parameters
Return value
A promise that resolves once the presentation has ended. If the VRDisplay
is not presenting when exitPresent()
is called, the promise will reject.
Examples
if (navigator.getVRDisplays) {
console.log("WebVR 1.1 supported");
navigator.getVRDisplays().then((displays) => {
if (displays.length > 0) {
vrDisplay = displays[0];
console.log("Display found");
btn.addEventListener("click", () => {
if (btn.textContent === "Start VR display") {
vrDisplay.requestPresent([{ source: canvas }]).then(() => {
console.log("Presenting to WebVR display");
const leftEye = vrDisplay.getEyeParameters("left");
const rightEye = vrDisplay.getEyeParameters("right");
canvas.width =
Math.max(leftEye.renderWidth, rightEye.renderWidth) * 2;
canvas.height = Math.max(
leftEye.renderHeight,
rightEye.renderHeight,
);
window.cancelAnimationFrame(normalSceneFrame);
drawVRScene();
btn.textContent = "Exit VR display";
});
} else {
vrDisplay.exitPresent();
console.log("Stopped presenting to WebVR display");
btn.textContent = "Start VR display";
vrDisplay.cancelAnimationFrame(vrSceneFrame);
drawScene();
}
});
}
});
}
Specifications
This method was part of the old WebVR API that has been superseded by the WebXR Device API. It is no longer on track to becoming a standard.
Until all browsers have implemented the new WebXR APIs, it is recommended to rely on frameworks, like A-Frame, Babylon.js, or Three.js, or a polyfill, to develop WebXR applications that will work across all browsers [1].
