0027 //! defines a Texture2Transform node of VRML specifying properties of geometry
0028 //! and its appearance.
0029 //! This node defines a 2D transformation applied to texture coordinates.
0030 //! This affect the way textures are applied to the surfaces of subsequent
0031 //! shapes.
0032 //! Transformation consisits of (in order) a non-uniform scale about an
0033 //! arbitrary center point, a rotation about that same point, and
0034 //! a translation. This allows a user to change the size and position of
0035 //! the textures on the shape.
0036 //! By default:
0037 //! myTranslation (0 0)
0038 //! myRotation (0)
0039 //! myScaleFactor (1 1)
0040 //! myCenter (0 0)
