Qt 3D: Scene3D QML Example▲
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.

Visualizing 3D Scenes▲
We set up the 3D scene and specify the entity to animate in main.qml:
Sélectionnez
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:
Sélectionnez
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 )
}
