Member Function Documentation

Matrix44 Matrix44::identity (    )  [inline, static]
 

Returns an identity matrix.

Matrix44 Matrix44::inverse (    )  const [inline]
 

Calculate the inverse matrix. There is also a C interface: 

 bool Mat44Inverse(Matrix44* dst, Matrix44* src);

Vector3 Matrix44::operator * (  const Vector3 &    v )  const [inline]
 

Vector transformation.

C Interface:
      void Mat44Transform(Vector3* r, const Matrix44* m, const Vector3* v);

Matrix44 Matrix44::operator * (  const Matrix44 &    m )  const [inline]
 

Matrix multiplication.

C Interface:
      void Mat44Multiply(Matrix44* result, Matrix44* m1, Matrix44* m2);

Matrix44::operator Float * (    )  const [inline]
 

Access the matrix contents as a flat array.

Float* Matrix44::operator[] (  int    row )  const [inline]
 

Access a matrix row as an array.

void Matrix44::setAngleAxisRotation (  Float    angle,
Float    x,
Float    y,
Float    z
)  [inline]
 

Set the rotational part of the matrix from an angle-axis representation.

Parameters:
angle  The rotation in degrees.
x,y,z  The normalized rotation axis.
C Interface:
      void Mat44SetAngleAxisRotation(Matrix44* m, Float angle, Float x, Float y, Float z);

void Matrix44::setEulerRotation (  Float    h,
Float    p,
Float    r
)  [inline]
 

Sets the rotational part of the matrix from euler angles.

Parameters:
h  Heading, or rotation about Y axis
p  Pitch, or rotation about X axis
r  Roll, or rotation about Z axis.
C Interface:
        void Mat44SetEulerRotation(Matrix44* m, Float h, Float p, Float r);

void Matrix44::setIdentity (    )  [inline]
 

Sets to the identity matrix.

void Matrix44::setQuaternion (  const Quaternion &    q )  [inline]
 

Set the rotational part of the matrix from a quaternion representation.

C Interface:
      void Mat44SetQuaternion(Matrix44* m, const Quaternion* q);

void Matrix44::setTranslation (  const Vector3 &    t )  [inline]
 

Set the positional part of the matrix.

void Matrix44::setTranslation (  Float    x,
Float    y,
Float    z
)  [inline]
 

Set the positional part of the matrix.
