// If a display is available, use it to present the scene
vrDisplay = displays[0];
console.log('Display found');
// Starting the presentation when the button is clicked:
// It can only be called in response to a user gesture
btn.addEventListener('click', function() {
vrDisplay.requestPresent([{ source: canvas }]).then(function() {
console.log('Presenting to WebVR display');
// Set the canvas size to the size of the vrDisplay viewport
var leftEye = vrDisplay.getEyeParameters('left');
var rightEye = vrDisplay.getEyeParameters('right');
canvas.width = Math.max(leftEye.renderWidth, rightEye.renderWidth) * 2;
canvas.height = Math.max(leftEye.renderHeight, rightEye.renderHeight);
drawVRScene();
