Variables

  Type Name Description
Protected variable bool bEnableAutoFocus Boolean to determine whether the camera should autofocus.
Protected variable bool bEnableAutomaticCameraOverlay Boolean to determine whether the AR camera feed should be drawn as an overlay.
Protected variable bool bEnableAutomaticCameraTracking Boolean to determine whether the virtual camera should track the device movement.
Public variable bool bGenerateCollisionForMeshData Boolean to determine whether the AR system should generate collision data from the mesh data.
Public variable bool bGenerateMeshDataFromTrackedGeometry Boolean to determine whether the AR system should generate mesh data that can be used for rendering, collision, NavMesh, and more.
Public variable bool bGenerateNavMeshForMeshData Boolean to determine whether the AR system should generate collision data from the mesh data.
Protected variable bool bHorizontalPlaneDetection Boolean to determine whether flat, horizontal surfaces are detected.
Public variable bool bRenderMeshDataInWireframe Boolean to determine whether the AR system should render the mesh data as wireframe.
Protected variable bool bResetCameraTracking Boolean to determine whether the AR system should reset camera tracking, such as its origin and transforms, when a new AR session starts.
