XRVisibilityMaskChangeEvent: indices property
Secure contextLimited availability
The indices read-only property of the XRVisibilityMaskChangeEvent interface specifies 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. If this array is empty, the whole region of the XRView will be drawn.
The number of contained values should therefore be a multiple of three. See vertices for more explanation.
Value
A Uint32Array.
Examples
See the main XRVisibilityMaskChangeEvent page for an example.
