WGEAnimationManipulator::RefPtr WGEViewer::animationMode | ( | bool | on = true | ) |
The (de-)activates the animation mode.
In animation mode, a special camera manipulator is used instead of the currently set. This manipulator can then play some animation path in realtime, frame-rate independent or in frame-per-frame mode which is useful if combined with the getScreenCapture() record function.
If animation mode is turned off again, the previously set manipulator / camera setting is restored.
