This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The rightBounds
property of the VRLayerInit
interface (dictionary) defines the right texture bounds of the canvas whose contents will be presented by the VRDisplay
.
Syntax
var myVRLayerInit = { };
myVRLayerInit.rightBounds = [0.5, 0.0, 0.5, 1.0]
;
Value
An array of four floating point values, which can take values from 0.0ā1.0:
- The left offset of the bounds.
- The top offset of the bounds.
- The width of the bounds.
- The height of the bounds.
If leftBounds
is not specified in the dictionary, the default value used is [0.5, 0.0, 0.5, 1.0]
.
Examples
// currently returns an empty array var layers = vrDisplay.getLayers(); if(navigator.getVRDisplays) { console.log('WebVR 1.1 supported'); // Then get the displays attached to the computer navigator.getVRDisplays().then(function(displays) { // If a display is available, use it to present the scene if(displays.length > 0) { 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'); // Here it returns an array of VRLayerInit objects var layers = vrDisplay.getLayers(); ... }); }); } }); }
VRLayerInit
objects look something like this:
{ leftBounds : [ ... ], rightBounds: [ ... ], source: canvasReference }
Note: The canvasReference
refers to the <canvas>
element itself, not the WebGL context associated with the canvas. The other two members are arrays
