- Animations are played through an Animator - Standard animations have a fixed duration and inherit from QVariantAnimation - The animation duration can be changed in the preferences - Fix animations when using the two arrows above the NaviCube - Start an animation or start and wait for an animation - Replaces standard camera animations (e.g. by selecting standard views or NaviCube) with FixedTimeAnimation - Replace View3DInventorViewer's CameraAnimation with FixedTimeAnimation - Replace OpenInventor navigation style infinite spin animation with SpinningAnimation - Stops an active animation when a new animation is started - Stops an active animation when the user starts dragging, panning or zooming - Refactor reorientCamera so it can be used in animations - Enable animations by default
