Graphics & User Interfaces

Paper coauthored by Changxi Zheng is Best Paper at Symposium on Computer Animation

Deployable 3D Linkages with Collision Avoidance describes a method for creating Hoberman-like mechanisms out of arbitrary 3D models. The method, which requires little user input, automatically avoids collisions among parts so object can expand and contract.

Tool lets designers interactively edit and optimize CAD models

Eitan Grinspun and Changxi Zheng worked with MIT researchers to create InstantCAD, a plugin providing real-time feedback on how design changes affect performance.

FontCode: Hiding information in plain text, unobtrusively and across file types

FontCode imperceptibly changes, or perturbs, the shapes of fonts in ordinary text to embed hidden information, without the existence of the secret information being perceived.
