SliceO_Class Matrix Transformation

Some classes are used to position the frames in space. For this we use a 4x4 transformation matrix. 2 matrix are provided:

m_old2new provide the transformation between a parent class and its children. m_new2old is the inverse of this matrix and provide the transformation from child to parent.

To save computation time, if the transformation matrix are identity matrix (no transformation) then the m_ident flag is set to "1".

Public:

m_ident (unsigned char)

A flag that signal that the transformation matrix is the identity matrix.

m_old2new (Matrix)

Transformation matrix from the parent system to this instance

m_new2old (Matrix)

Transformation matrix from this instance to the parent system.
