XRProjectionLayer
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
.
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. XRProjectionLayer.fixedFoveation
Experimental-
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 Experimental-
A boolean indicating that the XR compositor is not making use of depth buffer values when rendering the layer.
XRCompositionLayer.layout
Read only-
The layout type of the layer.
XRCompositionLayer.mipLevels
Read only-
The actual 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 re-rendered in the next frame.
XRProjectionLayer.textureArrayLength
Read only Experimental-
The layer's layer count for array textures when using
texture-array
as thetextureType
. XRProjectionLayer.textureHeight
Read only Experimental-
The height in pixels of the color textures of this layer.
XRProjectionLayer.textureWidth
Read only Experimental-
The width in pixels of the color textures of this layer.
Instance methods
Inherits methods from its parents, XRCompositionLayer
and EventTarget
.
EventTarget.addEventListener()
-
Registers an event handler of a specific event type on the
EventTarget
. XRCompositionLayer.destroy()
-
Deletes the underlying layer attachments.
EventTarget.dispatchEvent()
-
Dispatches an event to this
EventTarget
. EventTarget.removeEventListener()
-
Removes an event listener from the
EventTarget
.
