An Algebraic Model for Parameterized Shape Editing

An approach to high-level shape editing that adapts the shape's structure while maintaining its global characteristics. This paper's main contribution is a variational model that represents object structure in terms of linked regular patterns. The model yields an algebraic invariant that characterizes the shape, allowing for robust structure adaptation.

Steady Affine Motions and Morphs

SAM is a closed-form solution for computing a steady affine animation that morphs between two affine poses in 2D or 3D. This paper shows how to use SAM to produce morphs that interpolate a series of poses.

Interactive Surface Modeling Using Modal Analysis

A technique for speeding up deformation-based surface modeling systems. The technique is grounded in model reduction and employs vibration modes, modal derivatives, and a strategy for energy approximation.
