Hi Jan, well those tools are not really everyday use kind of tools for general surfacing, they're kind of finicky and advanced tools that can get the job done if you don't mind spending a lot of money and also time involved in learning all the ins and outs of operating them.

That's because the "create apples from applesauce" direction is just not a very natural path to work with things...

So they probably are not a practical solution for you unless you are focused on reverse engineering surface models from laser scanned objects as your primary focus for your work.
