To begin, we need a description of the object's internal structure.
Many real-world objects, both natural and man-made, are composed of layers of different materials built up over time, and we have structured our approach with layers as the core primitive. Our system is based on the observation that often the boundaries between the object's layers can be inferred from the primary interface. For example, a forensic artist can reconstruct a face from a skull using average muscle and skin thickness data. | ||
