63 \brief Provides a way to have a synchronous function executed each frame.
64
65 The QFrameAction provides a way to perform tasks each frame in a
66 synchronized way with the Qt3D backend. This is useful to implement some
67 aspects of application logic and to prototype functionality that can later
68 be folded into an additional Qt3D aspect.
69
70 For example, the QFrameAction can be used to animate a property in sync
71 with the Qt3D engine where a Qt Quick animation element is not perfectly
72 synchronized and may lead to stutters in some cases.
