The XRVisibilityMaskChangeEvent() constructor creates and returns a new XRVisibilityMaskChangeEvent object.

Syntax

new XRVisibilityMaskChangeEvent(type, options)

A string containing the name of the event, which is always visibilitymaskchange.

An object that, in addition of the properties defined in Event(), can have the following properties:

eye: The eye the mask applies to.
index: The index of the current XRView in the XRViewerPose.views array.
indices: A Uint32Array of values specifying the index position of each coordinate pair (not individual array index) inside the vertices array that define the triangles used to draw the currently visible part of the scene displayed in the XRView.
session: The XRSession to which the event belongs.
vertices: A Float32Array of coordinates representing the set of possible coordinate values that may be used in a visibility mask. If this array is empty, the whole region of the XRView will be drawn.

See the main XRVisibilityMaskChangeEvent page for an example.
