WebXRManager

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.

Properties

# .enabled : Boolean

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.

# .isPresenting : Boolean

Whether XR presentation is active or not. Default is false. This flag is read-only and automatically set by WebXRManager.

Methods

# .getController(index : Integer) → Group

index — The index of the controller.

Returns a Group representing the so called target ray space of the controller. Use this space for visualizing 3D objects that support the user in pointing tasks like UI interaction.

# .getControllerGrip(index : Integer) → Group

index — The index of the controller.

Returns a Group representing the so called grip space of the 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.

# .setFramebufferScaleFactor(framebufferScaleFactor : Float) → void

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.

# .setReferenceSpaceType(referenceSpaceType : String) → void

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.

Note: It is not possible to change the reference space type while presenting XR content.
