These angles - are similar to yaw, pitch and roll but are defined using only right hand - rotation with axes as defined by the right hand cartesian coordinate system. - - \image sensors-rotation.jpg - - The three angles are applied to the device in the following order. - - \list - \o Right-handed rotation z (-180, 180]. Starting from the y-axis and - incrementing in the counter-clockwise direction. - \o Right-handed rotation x [-90, 90]. Starting from the new - (once-rotated) y-axis and incrementing towards the z-axis. - \o Right-handed rotation y (-180, 180]. Starting from the new - (twice-rotated) z-axis and incrementing towards the x-axis. - \endlist - - Here is a visualization showing the order in which angles are applied. - - \image sensors-rotation-anim.gif - - The 0 point for the z angle is defined as a fixed, external entity and - is device-specific. While magnetic North is typically used as this - reference point it may not be. Do not attempt to compare values - for the z angle between devices or even on the same device if it has - moved a significant distance. - - If the device cannot detect a fixed, external entity the z angle will - always be 0 and the QRotationSensor::hasZ property will be set to false. - - The 0 point for the x and y angles are defined as when the x and y axes - of the device are oriented towards the horizon. Here is an example of - how the x value will change with device movement. - - \image sensors-rotation2.jpg - - Here is an example of how the y value will change with device movement. - - \image sensors-rotation3.jpg - - Note that when x is 90 or -90, values for z and y achieve rotation around - the same axis (due to the order of operations). In this case the y - rotation will be 0. -*/ - -/*! - \property QRotationReading::x - \brief the rotation around the x axis. - - Measured as degrees. - \sa {QRotationReading Units} -*/ - -qreal QRotationReading::x() const -{ - return d->x; -} - -/*! - Sets the rotation around the x axis to \a x. -*/ -void QRotationReading::setX(qreal x) -{ - d->x = x; -} - -/*! - \property QRotationReading::y - \brief the rotation around the y axis. - - Measured as degrees. - \sa {QRotationReading Units} -*/ - -qreal QRotationReading::y() const -{ - return d->y; -} - -/*! - Sets the rotation around the y axis to \a y. -*/ -void QRotationReading::setY(qreal y) -{ - d->y = y; -} - -/*! - \property QRotationReading::z - \brief the rotation around the z axis. - - Measured as degrees. - \sa {QRotationReading Units} -*/ - -qreal QRotationReading::z() const -{ - return d->z; -} - -/*! - Sets the rotation around the z axis to \a z. -*/ -void QRotationReading::setZ(qreal z) -{ - d->z = z; -} - -// ===================================================================== - -/*! - \class QRotationFilter - \ingroup sensors_filter - \inmodule QtSensors - - \brief The QRotationFilter class is a convenience wrapper around QSensorFilter. - - The only difference is that the filter() method features a pointer to QRotationReading - instead of QSensorReading. -*/ - -/*! - \fn QRotationFilter::filter(QRotationReading *reading) - - Called when \a reading changes.
