VRDisplayCapabilities.maxLayers

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 maxLayers read-only property of the VRDisplayCapabilities interface returns a number indicating the maximum number of VRLayerInits that the VR display can present at once (e.g. the maximum length of the array that Display.requestPresent() can accept.)

Note: This property was part of the old WebVR API. It has been superseded by the WebXR Device API.

Syntax

var maximumLayers = vrDisplayCapabilitiesInstance.maxLayers;

Value

A number, which must be 1 if VRDisplayCapabilities.canPresent is true, or 0 otherwise.

Examples

See VRDisplayCapabilities 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This property was part of the old WebVR API that has been superseded by the WebXR Device API.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].
