Such an rotation can easily be defined - in QML using the following code: - - \code - Item3D { - id: helicoptor - mesh: Mesh {source: "monkey.3ds"} - effect: Effect {} - cullFaces: "CullBackFaces" - - transform: [ - Rotation3D { - id: rotate1 - angle: 5 - axis: Qt.vector3d(1, 0, 0) - }, - Rotation3D { - id: rotate2 - angle: 5 - axis: Qt.vector3d(0, 1, 0) - }, - Rotation3D { - id: rotate3 - angle: 45 - axis: Qt.vector3d(0, 0, 1) - } - ] - - SequentialAnimation { - NumberAnimation {target: rotate1; property: "angle"; to : 360.0; duration: 3000; easing.type:easeOutQuad } - } - } - \endcode - - Notice here that we create a list of rotations for the \c transform - property of the container item. By doing this we allow rotations - around each of the axes individually in a manner which is conducive - to animation and interaction. - - Each of the rotations has an \c axis property which is a QVector3D. - This vector contains a value for each of the three components - corresponding to x, y, and z. In the above example, we first - rotate by 5 degrees about the x axis, then 5 degrees about the y - axis, and finally by 45 degrees about the z axis. - - By giving each rotation a unique \c id users can then refer to these - rotations in the QML source in order to perform rotational animations. - - \sa Translation3D, Scale3D -*/ - -class QGraphicsRotation3DPrivate -{ -public: - QGraphicsRotation3DPrivate() : axis(0, 0, 1), angle(0) {} - - QVector3D origin; - QVector3D axis; - qreal angle; -}; - -/*! - Create a 3D rotation transformation and attach it to \a parent. -*/ -QGraphicsRotation3D::QGraphicsRotation3D(QObject *parent) - : QGraphicsTransform3D(parent) - , d_ptr(new QGraphicsRotation3DPrivate) -{ -} - -/*! - Destroy this 3D rotation transformation. -*/ -QGraphicsRotation3D::~QGraphicsRotation3D() -{ -} - -/*! - \property QGraphicsRotation3D::origin - \brief the origin about which to rotate. - - The default value for this property is (0, 0, 0). -*/ - -/*! - \qmlproperty vector3D Rotation3D::origin - - The origin about which to rotate.
