VRDisplayCapabilities.canPresent

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The canPresent read-only property of the VRDisplayCapabilities interface returns a Boolean stating whether the VR display is capable of presenting content (e.g. through an HMD).

This is useful for identifying "magic window" devices that are capable of 6DoF tracking but for which VRDisplay.requestPresent() is not meaningful. If canPresent is false, calls to VRDisplay.requestPresent() will fail, and VRDisplay.getEyeParameters() will return null.

Syntax

var canIPresent = vrDisplayCapabilitiesInstance.canPresent;

Value

A Boolean.

Examples

TBD.
