The bottom box illustrates a different use of the textureTransform scale field. This caused us to show only one quarter of the original texture, but to map it onto the entire surface, effectively 'zooming in' on the texture. The top box illustrates another field of the textureTransform, rotation. As you can see, the bricks appear to be at an angle. This is because we have rotated the texture.
Rotations are simpler in texture transforms than in shapes, because textures are two dimensional.
So, all we need is an angle of rotation, and we can rotate the texture. Finally, the textureTransform node supports translation of a texture. This allows us to displace where the upper left hand corner of the texture will be placed on the surface. If we give positive values, the corner will be moved down and to the right, usually wrapping the image. We can also give negative values, moving the texture 'off' the shape to the left or top.
