0026 //! defines a MatrixTransform node of VRML specifying matrix and transform
0027 //! properties.
0028 //! This  node  defines  3D  transformation  with  a  4  by  4  matrix.
0029 //! By  default  :
0030 //! a11=1  a12=0  a13=0  a14=0
0031 //! a21=0  a22=1  a23=0  a24=0
0032 //! a31=0  a32=0  a33=1  a34=0
0033 //! a41=0  a42=0  a43=0  a44=1
0034 //! It  is  written  to  the  file  in  row-major  order  as  16  Real numbers
0035 //! separated  by  whitespace.  For  example ,  matrix  expressing  a  translation
0036 //! of  7.3  units  along  the  X  axis  is  written  as:
0037 //! 1  0  0  0   0  1  0  0   0  0  1  0   7.3 0  0  1
