详细描述

This helper implements a node that automatically rotates so that it is always pointed towards a specified node. The rotation only happens over X and Y axes.

For example, the following snippet keeps the cylinder pointed at the cube.

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 {} ]
    }
}
