A QML application that demonstrates visualizing a 3D scene.
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.
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.
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 ) }
