Hi Daiber,

i googled for your image and found this:

To me it looks it's made with a polygon modeler and ready to be subdivided, according to the text. So it's an subdivision surface model. Afaik you need a polygon model of your model and then subdivide it with Max's subd script. I bet also you need to experiment a bit in a polygon modeler to get those roundings right in the cells.
