Based on the clicked + buttons the \c{state} of the \c{mainview} changes. + + The 3D content is rendered using the \c{Scene3D} type. The state of the Audio Visualizer is + maintained in the \c{mainview}. It's passed on to the \c{visualizer} as it's needed for the bar + animations. + + \snippet audio-visualizer-qml/main.qml 1 + + \section1 Qt 3D Implementation + + The 3D elements of the example are created in the + \l{audio-visualizer-qml/Visualizer.qml}{Visualizer.qml}.
