Abstract

A method and an apparatus are described for interacting with a virtual object in a scene of an extended reality application, the method comprising: rendering a first scene of virtual objects based on a scene description, a first bounding space associated with a first coordinate system defining a first range of motion for virtual objects in the first scene, the scene description comprising a scene graph, wherein nodes of the scene graph include object nodes, each object node being associated with a virtual object and with object metadata, the object metadata comprising interaction information identifying virtual objects that are interactable and transform information associated with a position, orientation and/or scaling of an virtual object in the first scene; selecting nodes associated with interactable virtual objects based on the interaction information and rendering a second scene of interactable virtual objects associated with the selected nodes, a second bounding space associated with a second coordinate system defining a second range of motion for virtual objects in the second scene, the second range of motion being smaller than the first range of motion; receiving a user interface signal indicative of a user interacting with at least one of the interactable virtual objects in the second scene, the user interface signal triggering an action associated with the at least one interactable virtual object, the action causing a change in the position, orientation and/or scaling of the at least one interactable virtual object in the second scene; determining a change in the position, orientation and/or scaling of an interactable virtual object in the first scene that corresponds to the at least one interactable virtual object in the second scene, the determining being based on the change in the position, orientation and/or scaling of the at least one interactable virtual object in the second scene and a coordinate transform between the first and second coordinate system; and, updating the scene description file, the updating including updating the transform information associated the interactable virtual object in the first scene based on the change in the position, orientation and/or scaling of the interactable virtual object in the first scene.
