DualSDF: Semantic Shape Manipulation Using a Two-Level Representation

Figure 1 : DualSDF represents shapes using two levels of granularity, allowing users to manipulate high resolution shapes (odd rows) with high-level concepts through manipulating a proxy primitive-based shape (even rows). Simple editing operations on individual primitives (colored in blue) are propagated to the other primitives and the fine-grained model in a semantically meaningful manner. Above, we illustrate how an existing shape (inside the red box) can be modified semantically by adjusting the radius of a primitive (fuselage diameter on the airplane) or the distance between two primitives (wheelbase of a car).
