XRCylinderLayer
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
The XRCylinderLayer
interface of the WebXR Device API is a layer that takes up a curved rectangular space in the virtual environment. Only the front of the layer is visible.
XRCylinderLayer
requires the layers
feature to be enabled for the XRSession
. You can request it in XRSystem.requestSession()
.
To create a new XRCylinderLayer
, call either:
XRWebGLBinding.createCylinderLayer()
for a WebGL opaque texture layer, orXRMediaBinding.createCylinderLayer()
for an HTML<video>
playback layer.
To present layers to the XR device, add them to the layers
render state using XRSession.updateRenderState()
.
Properties
Inherits properties from its parent, XRCompositionLayer
.
XRCylinderLayer.aspectRatio
-
A number indicating the ratio of the visible cylinder section. It is the ratio of the width of the visible section of the cylinder divided by its height. The width is calculated by multiplying the
radius
with thecentralAngle
. XRCylinderLayer.centralAngle
-
A number indicating the angle in radians of the visible section of the cylinder.
XRCylinderLayer.radius
-
A number indicating the radius of the cylinder.
XRCylinderLayer.space
-
An
XRSpace
representing the layer's spatial relationship with the user's physical environment. XRCylinderLayer.transform
-
An
XRRigidTransform
representing the offset and orientation relative tospace
.
Methods
Inherits methods from its parents, XRCompositionLayer
and EventTarget
.
Events
redraw
-
Sent to the
XRCylinderLayer
object when the underlying resources of the layer are lost or when the XR Compositor can no longer reproject the layer. If this event is sent, authors should redraw the content of the layer in the next XR animation frame.
