Virtual Cuts


Pork is big business in Denmark. Tiny improvements on each individual product translates into several million dollars saved. In 2009, a growing interest in product optimization coupled with the recent introduction of CT-scanning in the Danish abattoirs paved the way for new methods of product optimization.

Enter virtual realistic cuts, aka. PorkCAD. Utilizing CT-scanned data from a real pig carcass, the tool provides a new edge in pork product development, allowing sellers and buyers a better way to communicate the product that they bring to the market together. Using a Phantom Omni, the user is able to create, modify, and delete planar cuts in an effort to virtually create the type of pork product the seller is interested in.

Lessons Learned

PorkCAD is to date still the longest and most cohesive project I've ever been involved in. It was a learning experience most of the way, and while I must admit my interest in the project did not remain constant throughout, it helped give me perspective and realize that not all projects have to turn out the way you expect. Lessons can still be learned and valuable experience is still yours, as long as you are willing to look and listen. One of the greatest lessons learned from both the design and testing of the system presented was how quickly and 'easily' senior personnel were able to handle the final product. Nothing can even come close to scratch the intuitive nature of analogous behavior. If you have identical behavior occurring both on- and off-screen, then you're on the right path.
