web api instance property
VRLayerInit: leftBounds property
The leftBounds property of the VRLayerInit interface (dictionary) defines the left texture bounds of the canvas whose contents will be presented by the VRDisplay.
[!NOTE] This property was part of the old WebVR API. It has been superseded by the WebXR Device API.
Value
An array of four floating point values, which can take values from 0.0–1.0.
- 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 [0.0, 0.0, 0.5, 1.0].
Examples
See VRLayerInit for example code.
Specifications
This property was part of the old WebVR API that has been superseded by the WebXR Device API.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. Read Meta’s Porting from WebVR to WebXR guide for more information.
