Constructor & Destructor Documentation

Matrix2C (    )

Default constructor.

Matrix2C (  const Matrix2C &    rMat )

Copy constructor.

Matrix2C (  const float32 *    pMat )

Contructor from array of floats. Creates a new vector with the values as the array pointed by the argument. The array should contain 6 values, 2 for each row in the matrix. The rows in the array are arranged linearly.

virtual ~Matrix2C (    )  [virtual]

Default destructor.
