<p>A QWidget-based application with a QML scene containing a 3D scene.</p>
<!-- @@@widgets-scene3d -->
<!-- $$$widgets-scene3d-description -->
<div class="descr"> <a name="details"></a>
<p class="centerAlign"><img src="images/widgets-scene3d.png" alt="" /></p><p><i>widgets-scene3D</i> demonstrates visualizing a 3D scene from a QWidget-based application using QQuickWidget.</p>
<p>The actual 3D scene is the same as in the <i>scene3d</i> example.</p>
<p>This approach is different from the one based on QWidget::createWindowContainer() demonstrated in <i>basicshapes-cpp</i> because it does not create a native window for the Qt 3D content. Rather, it uses QQuickWidget, a genuine QWidget subclass to compose the Qt Quick and Qt 3D content together with the traditional widgets.</p>
<p><b>Note: </b>Be aware of the performance implications. While this approach is very flexible in the sense that it allows mixing QML and Qt 3D with widgets without clipping or stacking issues, using <a href="qml-qtquick-scene3d-scene3d.html">Scene3D</a> in a QQuickWidget involves rendering to offscreen render targets (via framebuffer objects) twice. This is not always desirable for more complex scenes. For those the native window based approach shown in <i>basicshapes-cpp</i> will likely be a better choice.</p><a name="running-the-example"></a>
