double y() const
Returns y-component of the quaternion.
The vpRotationMatrix considers the particular case of a rotation matrix.
double w() const
Returns w-component of the quaternion.
double z() const
Returns z-component of the quaternion.
double x() const
Returns x-component of the quaternion.
Defines a quaternion and its basic operations.
