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.

We set up the 3D scene and specify the entity to animate in main.qml :
Scene3D { id: scene3d anchors.fill: parent anchors.margins: 10 focus: true aspects: ["input", "logic"] cameraAspectRatioMode: Scene3D.AutomaticAspectRatio AnimatedEntity { id: rootEntity } }
We specify the active camera in scene3d/AnimatedEntity.qml :
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 ) }
