VRLayerInit: leftBounds property

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.

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 It has been superseded by the WebXR Device API.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This property was part of the old WebVR API that has been superseded by the WebXR Device API.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 [1].
