Documentation

4x4 MatrixOld for storage & manipulation of transformations in scene graph. Provides basic maths operations, IO and via osg::Object reference counting. You can directly load the MatrixOld with OpenGL's LoadMatrixOldf() function via the public member _mat as the MatrixOld is stored in the OpenGL format. Caution: The disadvantage of this feature is, that the MatrixOld access is 'transposed' if you compare it with the standard C/C++ 2d-array-access convention . I.e. _mat[i][j] accesses the ith column of the jth row in the 4x4 MatrixOld.
