[Bf-cycles] Procedural Noise clarity

[Constantin Rahn]

Hi,

@Daniel with the offset (transform in mapping node) you can only animate 
the x,y or z axis. This will result in a translation in one of the axis.
You can use this for a 2D mapped texture and animate the z-axis (in my 
sample the texture on the plane). But I need the same effect for 
generated mapping where I use all three axis for the mapping (in my 
sample the sphere).  To animate the texture itself (evolving clouds) you 
need a 4th dimension. It looks like the animated 2D mapped effect, but 
in 3d space.
You can see the translation on the sphere. The surface of the sphere 
should look like the animation on the plane with no translation. But for 
this I would need a higher dimension (4th dimension).
