The other cool thing about an OOP approach to this problem is that you can hide your optimized LUT behind the OOP if you're careful about the design of it. This lets you have your cake and eat it too. Your users who might be more comfortable with an OOP approach get a way to declare the kinds of shapes they're interested in and the number of shapes they want to work with. Then you can take responsibility for building a LUT that meets their needs and give them the supporting optimizations they need to be successful.
