Its data stores 16-value array of column-major matrix elements. I chose column-major format to be compatible with OpenGL You can use cyMatrix4f with cyPoint3f and cyPoint4f to transform 3D and 4D points. Both post-multiplication and pre-multiplication are supported. Other Public Methods void  SetTranspose ()   Transpose this matrix. cyMatrix4f  Transpose () const   return Transpose of this matrix void  Invert ()   Invert this matrix. void  GetInverse (cyMatrix4f &inverse)   Get the inverse of this matrix. cyMatrix4f  GetInverse ()   Get the inverse of this matrix.
