Detailed Description

A 4x4 matrix.

Author:

Patrik Stellmann

The data is stored as a 4x4 array of TReal row by row.

---

Constructor & Destructor Documentation

RCMatrix::RCMatrix (   )  [inline]

Creates an identity matrix.

RCMatrix::RCMatrix (  const TReal *  naSource, TBool  b3x4 = true )  [inline, explicit]

Creates a matrix from an array of values. If b3x4 is true the specified array is expected to contain 3 rows of 4 values each and the 4th row is set to zero with a 1 in the last cell. Otherwise 16 values are copied from the array row by row.

RCMatrix::RCMatrix (  const RCQuaternion &  Source  )  [inline]

Creates a rotation matrix from the specified quaternion.

RCMatrix::RCMatrix (  const RCMatrix &  Source  )  [inline]

Creates a copy of the specified matrix.

Member Function Documentation

const TReal * RCMatrix::Data (   )  const [inline]

Returns a constant pointer to the internally storred data which is a 4x4 array of TReal while the elements are stored row by row.

TBool RCMatrix::FromString (  const RCString &  sValue  )  [virtual]

3 values -> diagonal matrix with these values 9 values -> 3x3 matrix row by row 12 values -> 3x4 matrix row by row 16 values -> 4x4 matrix row by row Implements BASE::RCStringValueInterface.

RCVector RCMatrix::operator * (  const RCVector &  rhs  )  const [inline]

Returns the result of the specified vector multiplied by this matrix from the left.

RCMatrix RCMatrix::operator * (  const RCMatrix &  rhs  )  const [inline]

Returns the result of specified matrix ,ultiplied by this one from the left.

const RCMatrix & RCMatrix::operator *= (  const RCMatrix &  rhs  )

Multiplies the specified matrix with this one from the left(!).

const TReal & RCMatrix::operator() (  TInt  nRow, TInt  nCol )  const [inline]

Returns a reference to the element specified by the arguments. The arguments must be both less than 4.

TReal & RCMatrix::operator() (  TInt  nRow, TInt  nCol )  [inline]

Returns a reference to the element specified by the arguments. The arguments must be both less than 4.

const RCMatrix & RCMatrix::operator= (  const RCQuaternion &  Source  )

Assigns the rotation matrix represented by the specified quaternion to this one.

const RCMatrix & RCMatrix::operator= (  const RCMatrix &  Source  )  [inline]

Assigns the specified matrix to this one.
