This class represents an abstraction of the WebXR Device API and is internally used by WebGLRenderer. WebXRManager also provides a public interface that allows users to enable/disable XR and perform XR related tasks like for instance retrieving controllers.
Whether the manager's XR camera should be automatically updated or not. Default is true.
This flag notifies the renderer to be ready for XR rendering. Default is false. Set it to true if you are going
to use XR in your app.
Whether XR presentation is active or not. Default is false. This flag is read-only and automatically set by WebXRManager.
x — screen X coordinate.
y — screen Y coordinate.
hitCallback — callback executed upon ray hit.
missCallback — callback executed upon ray miss.
Initializes asynchronous hit testing in AR mode.
Returns an instance of ArrayCamera which represents the XR camera of the active XR session. For each view it holds a separate camera object in its cameras property.
The camera's fov is currently not used and does not reflect the fov of the XR camera. If you need the fov on app level,
you have to compute in manually from the XR camera's projection matrices.
index — The index of the controller.
Returns a Group representing the so called target ray space of the XR controller. Use this space for visualizing 3D objects that support the user in pointing tasks like UI interaction.
index — The index of the controller.
Returns a Group representing the so called grip space of the XR controller.
Use this space if the user is going to hold other 3D objects like a lightsaber.
Note: If you want to show something in the user's hand AND offer a pointing ray at the same time, you'll want to attached the handheld object to the group returned by .getControllerGrip() and the ray to the group returned by .getController(). The idea is to have two different groups in two different coordinate spaces for the same WebXR controller.
Returns the amount of foveation used by the XR compositor for the projection layer.
index — The index of the controller.
Returns a Group representing the so called hand or joint space of the XR controller.
Use this space for visualizing the user's hands when no physical controllers are used.
Returns the set of planes detected by WebXR's plane detection API.
Returns the reference space.
Returns the XRSession object which allows a more fine-grained management of active WebXR sessions on application level.
foveation — The foveation to set.
Specifies the amount of foveation used by the XR compositor for the layer. Must be a value between 0 and 1.
framebufferScaleFactor — The framebuffer scale factor to set.
Specifies the scaling factor to use when determining the size of the framebuffer when rendering to a XR device.
The value is relative to the default XR device display resolution. Default is 1. A value of 0.5 would specify
a framebuffer with 50% of the display's native resolution.
Note: It is not possible to change the framebuffer scale factor while presenting XR content.
referenceSpace — A custom reference space.
Can be used to configure a custom reference space which overwrites the default reference space.
referenceSpaceType — The reference space type to set.
Can be used to configure a spatial relationship with the user's physical environment. Depending on how the user moves in 3D space, setting an appropriate reference space can improve tracking. Default is local-floor. Please check out the MDN for possible values and their use cases.
Updates the state of the XR camera. Use this method on app level if you set .cameraAutoUpdate to false.
The method requires the non-XR camera of the scene as a parameter. The passed in camera's transformation is automatically
adjusted to the position of the XR camera when calling this method.
Note: It is not possible to change the reference space type while presenting XR content.
