Qt 3D: Scene3D QML Example

Scene3D 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.

Running the Example

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

Visualizing 3D Scenes

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 {}
        }

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 )
    }
