详细说明

该辅助组件实现了一个节点,该节点会自动旋转,以确保其始终指向指定的节点。旋转仅沿 X 和 Y 轴进行。

例如,以下代码片段可使圆柱体始终指向立方体。

View3D {
    anchors.fill: parent
    camera: camera

    PerspectiveCamera {
        id: camera
    }

    DirectionalLight {}

    LookAtNode {
        target: cube

        Model {
            id: cylinder
            source: "#Cone"
            eulerRotation.x: -90
            materials: [
                PrincipledMaterial {}
            ]
        }
    }

    Model {
        id: cube
        position: Qt.vector3d(300, 300, 0);
        source: "#Cube"
        materials: [ PrincipledMaterial {} ]
    }
}
