Free-Form Curve Generation By Recursive Subdivision of Polygonal Strip Complexes
 
A new method for designing free-form curves by recursive subdivision of polygonal complexes and some of its applications in computer-aided geometric design and computer graphics such as physically based animation, shape control, interpolation of meshes or curves, and trimming of surfaces.

Interactive CSG
 
A novel space subdivision allows interactive construction of CSG through direct manipulation of the component objects. Algebraic surfaces are polygonized for hardware display, preserving cut edges and surface shading.

A Level-Set Approach for the Metamorphosis of Solid Models
 
An active deformable surface, represented as a level set (iso-surface) of a discretely sampled scalar function of three dimensions, that smoothly changes (morphs) one solid model into another.
