+    \title Qt 3D Studio Runtime: Layers in Qt Quick Example
+    \ingroup qt3dstudioruntime2-examples-qml
+    \brief Demonstrates using the View3D element in a Qt Quick application
+
+    \image layersinquick.png
+
+    \e {This example demonstrates basic usage of the View3D element in Qt Quick applications}
+
+    \include examples-run.qdocinc
+
+    \section1 Description
+
+    This example consists of a simple C++ main() function that sets up a
+    QQuickView and a QML scene demonstrating the usage of the \l Studio3D and
+    \l View3D QML types. This combination is important because once a \l View3D
+    element is added to the Qt Quick scene, the behavior of \l Studio3D changes
+    significantly: instead of displaying the composited image of all layers
+    from the Qt 3D Studio presentation loaded from the \c{.uip} file(s), it
+    rather delegates the rendering of the individual layers to the \l View3D
+    items.
+
+    This offers a lightweight and efficient way to create user interfaces that
+    have 3D content present in a number of different areas in the window. In
+    contrast, the traditional approach treats the 3D view as a "box", a
+    rectangular area defined by the bounds of the \l Studio3D element. With \l
+    View3D this limitation can be lifted since each layer from the 3D scene can
+    be managed (positioned, transformed, blended) individually via a \l View3D
+    instance dedicated to that layer.
+
+    In the example the source \c{.uip} file has two layers. Both have
+    transparent backgrounds, one contains a single cube, while the other a
+    sphere and some text nodes. When it comes to the \l Studio3D item, the QML
+    code is no different from other examples. What makes it special is the
+    inclusion of two \l View3D items, each referencing a layer from the
+    \c{.uip} presentation by name.
