Qt Quick 3D - XR Freeform Teleportation Example

概述

This example shows how to move to places in the virtual environment using a simple freeform teleportation system, a non-continuous form of movement.

控件

When you run the example, use the following controls for navigation.

动作	Control
Rotation	Left and Right stick on the right controller
Aim and Teleport	Forward stick on the right controller

实现

You can easily re-use FreeformTeleporter in other projects, as all the logic is contained within that type.

FreeformTeleporter {
    id: teleporter
    rayPicker: xrView
    cameraOrigin: xrOrigin
    camera: xrOrigin.camera
    beamHandle: xrRightController
    onDoTeleportation: (cameraOriginPosition)=> {
                           xrOrigin.position = cameraOriginPosition
                       }
    onDoRotation: (cameraOriginRotation, cameraOriginPosition)=> {
                      xrOrigin.rotation = cameraOriginRotation
                      xrOrigin.position = cameraOriginPosition
                  }
}
						

The FreeformTeleporter component has the following properties that need to be set:

var rayPicker
						

The rayPicker property can be any object that implements a rayPick method. In this example, we are using XrView 's built-in ray-picking method.

Node cameraOrigin
						

The cameraOrigin property is the center of the camera's local reference space. In Xr this will be the location where tracked items, like the camera, will be placed relative to. We will, therefore, use the XrOrigin node as the cameraOrigin.

Node camera
						

The camera property contains the camera used to render the scene. In this example, we use the tracked XrCamera we created earlier.

Node beamHandle
						

The beamHandle property is the Node used as the teleportation beam's start point. In this example, we use the right controller xrRightController as the beamHandle.
