Detailed Description

A quaternion is a quaternion.

Constructor & Destructor Documentation

Quaternion::Quaternion (  Float    w,
Float    x,
Float    y,
Float    z
)  [inline]
 

Initializing constructor.

Quaternion::Quaternion (  const Quaternion &    q )  [inline]
 

Initializing constructor.

Member Function Documentation

Quaternion Quaternion::inverse (    )  const [inline]
 

Invert the quaternion (returns the opposite rotation).

void Quaternion::normalize (    )  [inline]
 

Make this a unit quaternion.

C Interface:
      void QuatNormalize(Quaternion* q);

Quaternion Quaternion::operator * (  const Quaternion &    q )  const [inline]
 

Concatonate two rotations.

void Quaternion::operator *= (  const Quaternion &    q )  [inline]
 

Concatonate two rotations.

Quaternion& Quaternion::operator= (  const Quaternion &    q )  [inline]
 

Assignment operator.

void Quaternion::set (  Float    w,
Float    x,
Float    y,
Float    z
)  [inline]
 

Set the quaternion components.

void Quaternion::setAngleAxisRotation (  Float    angle,
Float    x,
Float    y,
Float    z
)  [inline]
 

Initialize the quaternion from angle-axis representation.

Parameters:
angle  The angle, in degrees.
x,y,z  The normalized axis components.
C Interface:
      void QuatSetAngleAxisRotation(Quaternion* q, Float angle, Float x, Float y, Float z);

void Quaternion::setEulerRotation (  Float    h,
Float    p,
Float    r
)  [inline]
 

Initialize the quaternion from a euler representation.

C Interface:
      void QuatSetEulerRotation(Quaternion* q, Float h, Float p, Floar r);

void Quaternion::setIdentity (    )  [inline]
 

Sets to the identity matrix.
