XRCompositionLayer

The XRCompositionLayer interface of the WebXR Device API is a base class that defines a set of common properties and behaviors for WebXR layer types. It is not constructable on its own.

Several layer types inherit from XRCompositionLayer:

• XREquirectLayer
• XRCubeLayer
• XRCylinderLayer
• XRProjectionLayer
• XRQuadLayer

XRCompositionLayer itself inherits from the general XRLayer class (which inherits from EventTarget).

XRCompositionLayer.blendTextureSourceAlpha

A boolean enabling the layer's texture alpha channel.

XRCompositionLayer.chromaticAberrationCorrection

A boolean enabling optical chromatic aberration correction for the layer if the device supports it, null otherwise.

XRCompositionLayer.layout Read only

The layout type of the layer.

XRCompositionLayer.mipLevels Read only

The number of mip levels in the color and texture data for the layer.

XRCompositionLayer.needsRedraw Read only

A boolean signaling that the layer should be rerendered in the next frame.

Inherits methods from its parent, EventTarget.

XRCompositionLayer.destroy()

Deletes the underlying layer attachments.
