TextureTransform

This node allows you to perform simple geometric transformations, scale, rotation, and translation, on texture coordinates, see the TextureCoordinate node. This node is defined inside an Appearance node. 

Syntax: 
TextureTransform { 
scale 1 1 
rotation 0 
center 0 0 
translation 0 0 
The value of the center field specifies the center point about which rotation and scale takes place. 

When all fields are used in combination then the coordinates specified in the TextureCoordinate node are first scaled and rotated about the center point, and finally translated.
