0028 //! defines a Texture2Transform node of VRML specifying properties of geometry
0029 //! and its appearance.
0030 //! This  node  defines  a 2D  transformation  applied  to  texture  coordinates.
0031 //! This  affect  the  way  textures  are  applied  to  the  surfaces  of  subsequent
0032 //! shapes.
0033 //! Transformation  consisits  of(in  order)  a  non-uniform  scale  about  an
0034 //! arbitrary  center  point,  a  rotation  about  that  same  point,  and
0035 //! a  translation.  This  allows  a  user  to  change  the  size  and  position  of
0036 //! the  textures  on  the  shape.
0037 //! By  default  :
0038 //! myTranslation (0 0)
0039 //! myRotation (0)
0040 //! myScaleFactor (1 1)
0041 //! myCenter (0 0)
