<p class="centerAlign"><img src="images/scene3d.png" alt="" /></p><p>This example demonstrates visualizing a 3D scene from a Qt Quick application. The 3D scene contains a single active camera and a single active light source. Visualized data is assumed to be at a fixed location.</p>

<p>To run the example from Qt Creator, open the <b>Welcome</b> mode and select the example from <b>Examples</b>. For more information, visit Building and Running an Example.</p>

<p>We set up the 3D scene and specify the entity to animate in <i>main.qml</i>:</p>
<pre class="cpp">
Scene3D {
id: scene3d
anchors.fill: parent
anchors.margins: 10
focus: true
aspects: ["input", "logic"]
cameraAspectRatioMode: Scene3D.AutomaticAspectRatio
AnimatedEntity {}
}
</pre>
<p>We specify the active camera in <i>scene3d/AnimatedEntity.qml</i>:</p>
<pre class="cpp">
Camera {
id: camera
projectionType: CameraLens.PerspectiveProjection
fieldOfView: 45
nearPlane : 0.1
farPlane : 1000.0
position: Qt.vector3d( 0.0, 0.0, 40.0 )
upVector: Qt.vector3d( 0.0, 1.0, 0.0 )
viewCenter: Qt.vector3d( 0.0, 0.0, 0.0 )
}
