XRProjectionLayer

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The XRProjectionLayer interface of the WebXR Device API is a layer that fills the entire view of the observer and is refreshed close to the device's native frame rate.

XRProjectionLayer is supported by all XRSession objects (no layers feature descriptor is needed).

To create a new XRProjectionLayer, call XRWebGLBinding.createProjectionLayer(). To present layers to the XR device, add them to the layers render state using XRSession.updateRenderState().

XRProjectionLayer objects don't have an associated XRSpace, because they render to the full frame.

Instance properties

Inherits properties from its parent, XRCompositionLayer and EventTarget.

XRProjectionLayer.fixedFoveation

A number indicating the amount of foveation used by the XR compositor for the layer. Fixed Foveated Rendering (FFR) renders the edges of the eye textures at a lower resolution than the center and reduces the GPU load.

XRProjectionLayer.ignoreDepthValues Read only

A boolean indicating that the XR compositor is not making use of depth buffer values when rendering the layer.

XRProjectionLayer.textureArrayLength Read only

The layer's layer count for array textures when using texture-array as the textureType.

XRProjectionLayer.textureHeight Read only

The height in pixels of the color textures of this layer.

XRProjectionLayer.textureWidth Read only

The width in pixels of the color textures of this layer.

Instance methods

Inherits methods from its parents, XRCompositionLayer and EventTarget.
