Learning Generative Models of Shape Handles

Gallery of 3D shapes generated as sets of handles (zoom for details). We propose a class of generative models for synthesizing sets of handles -lightweight proxies that can be easily utilized for high-level tasks such as shape editing, parsing, animation etc. Our model can generate sets with different cardinality and is flexible to work with various types of handles, such as sphere-mesh handles [37] (first and third figures) and cuboids (middle figure).
