LinkEdit: Interactive Linkage Editing Using Symbolic Kinematics

This paper presents an interactive tool for editing the shape and motion of existing linkages. To enable interactive performance, the method departs from the typical constraint-based simulation in favor of a symbolic-kinematics algorithm that uses closed-form expressions to determine the motion of a linkage and its derivatives.

Fab Forms: Customizable Objects for Fabrication With Validity and Geometry Caching

This paper addresses the problem of allowing casual users to customize parametric models for 3D printing while maintaining their validity. The approach precomputes valid regions of the design space and expensive geometry components for a parametric design, allowing interactive fail-safe customization at run-time using an automatically generated web interface.

Computational Design of Twisty Joints and Puzzles

The first computational method that allows ordinary users to create complex twisty joints and puzzles. Given a 3D model and a small subset of rotation axes, the method automatically creates the shapes of pieces that can be 3D printed and assembled into a twisty puzzle.

Reduced-Order Shape Optimization Using Offset Surfaces

This novel method for reduced-order shape optimization of 2-manifold surfaces aims to satisfy global objectives by displacing an offset surface derived from a given initial shape. The main contribution is an elegant and efficient basis-reduction approach for the resulting constrained optimization problem.
