Ring's anatomy - parametric design of wedding rings

We present a use case that demonstrates the effectiveness of procedural shape modeling for mass customization of consumer products. We show a metadesign that is composed of a few well-defined procedural shape building blocks. It can generate a large variety of shapes and covers most of a design space defined by a collection of exemplars, in our case wedding rings. We describe the process of model abstraction for the shape space spanned by these shapes, arguing that the same is possible for other shape design spaces as well.
