ClipPlane in qml

[HB76]

Hi everyone !

I am looking for a way to display a cut view (to see the section) of a 3D model and I found the ClipPlane qml type but after a try in the "simple qml" example I didn't saw anything.

Do you have any idea of how to use this class ?

Here is the qml code I ran :

    id: sceneRoot

    Camera {
        id: camera
        projectionType: CameraLens.PerspectiveProjection
        fieldOfView: 45
        aspectRatio: 16/9
        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 )
    }

    ClipPlane {
        normal: Qt.vector3d(0,0,1)
        distance: 0
        planeIndex: 0
    }

    OrbitCameraController {
        camera: camera
    }

    components: [
        RenderSettings {
            activeFrameGraph: ForwardRenderer {
                clearColor: Qt.rgba(0, 0.5, 1, 1)
                camera: camera
                showDebugOverlay: true
            }
        },
        // Event Source will be set by the Qt3DQuickWindow
        InputSettings { }
    ]

    PhongMaterial {
        id: material
    }

    TorusMesh {
        id: torusMesh
        radius: 5
        minorRadius: 1
        rings: 100
        slices: 20
    }

    Transform {
        id: torusTransform
        scale3D: Qt.vector3d(1.5, 1, 0.5)
        rotation: fromAxisAndAngle(Qt.vector3d(1, 0, 0), 45)
    }

    Entity {
        id: torusEntity
        components: [ torusMesh, material, torusTransform ]
    }

    SphereMesh {
        id: sphereMesh
        radius: 3
    }

    Transform {
        id: sphereTransform
        property real userAngle: 0.0
        matrix: {
            var m = Qt.matrix4x4();
            m.rotate(userAngle, Qt.vector3d(0, 1, 0));
            m.translate(Qt.vector3d(20, 0, 0));
            return m;
        }
    }

    QQ2.NumberAnimation {
        target: sphereTransform
        property: "userAngle"
        duration: 10000
        from: 0
        to: 360

        loops: QQ2.Animation.Infinite
        running: true
    }

    Entity {
        id: sphereEntity
        components: [ sphereMesh, material, sphereTransform ]
    }
}
