Ok. Never needed something like this.

Ah. No in that case I don't have a "ready" vectormade Variable that holds
the values. The Cell-Items are accessed during ray-tracing and shading.
But I have to say, I have not written the shading code so I don't know
which is the best way to access the items from the view of the shading
algo.
