Constructor & Destructor Documentation

FMQuaternion::FMQuaternion (   )  [inline]

Creates an empty FMQuaternion. The default values are non deterministic.

FMQuaternion::FMQuaternion (  float  _x, float  _y, float  _z, float  _w )  [inline]

Creates the FMQuaternion with the given component values. Parameters: _x  The i component. _y  The j component. _z  The k component. _w  The scalar component.

FMQuaternion::FMQuaternion (  const FMVector3 &  axis, float  angle )

Creates the FMQuaternion from a given axis and angle of rotation. Parameters: axis  The axis of rotation. angle  The angle of rotation in radians.

Member Function Documentation

static FMQuaternion FMQuaternion::EulerRotationQuaternion (  float  _x, float  _y, float  _z )  [static]

Get the FMQuaternion representation of the Euler rotation angles. Parameters: _x  The rotation about the x-axis (roll), in radians. _y  The rotation about the y-axis (pitch), in radians. _z  The rotation about the z-axis (yaw), in radians.

FMQuaternion FMQuaternion::operator * (  const FMQuaternion &  q  )  const

Applys quaternion multiplication of the given FMQuaternion with this FMQuaternion and returns the value. Parameters: q  The FMQuaternion multiply with. Returns: The resulting FMQuaternion.

FMQuaternion::operator const float * (   )  const [inline]

Get this FMQuaternion as an array of floats. Returns: The float array.

FMQuaternion::operator float * (   )  [inline]

Get this FMQuaternion as an array of floats. Returns: The float array.

FMQuaternion& FMQuaternion::operator= (  const float *  v  )  [inline]

Assign this FMQuaternion to the given float array. Assigns each coordinate of this FMQuaternion to the elements in the float array. The first element to the i component, the second to the j, the third to the k, and the forth to the scalar. It returns this FMQuaternion. Parameters: v  The float array to assign with. Returns: This FMQuaternion.
