The concept of symmetry has received significant attention in computer graphics and
computer vision research in recent years. Numerous methods have been proposed to find …

We present an interactive design system that allows non-expert users to create animated
mechanical characters. Given an articulated character as input, the user iteratively creates …

Additive manufacturing (3D printing) is commonly used to produce physical models for a
wide variety of applications, from archaeology to design. While static models are directly …

For the task of mobility analysis of 3D shapes, we propose joint analysis for simultaneous
motion part segmentation and motion attribute estimation, taking a single 3D model as input …

Computer Aided Design (CAD) typically involves tasks such as adjusting the camera
perspective and assembling pieces in free space that require specifying 6 degrees of …

Shape structure is about the arrangement and relations between shape parts. Structure-
aware shape processing goes beyond local geometry and low level processing to analyze …

We introduce an algorithm for unsupervised co-segmentation of a set of shapes so as to
reveal the semantic shape parts and establish their correspondence across the set. The …

Engineers routinely design for strength and stiffness. Steel and concrete prevent deflections
in buildings, and machines resort to rigid articulation in order to avoid deformations. But …

We present a pipeline of algorithms that decomposes a given polygon model into parts such
that each part can be 3D printed with high (outer) surface quality. For this we exploit the fact …
