3D Reconstruction of Curved Objects from Single 2D Line Drawings
An important research area in computer vision is developing algorithms that can reconstruct the 3D surface of an object represented by a single 2D line drawing. Previous work on...

Voronoi diagram computations for planar NURBS curves
We present robust and efficient algorithms for computing Voronoi diagrams of planar freeform curves. Boundaries of the Voronoi diagram consist of portions of the bisector curves b...

Localized-hierarchy surface splines (LeSS)
An explicit spline representation of smooth free-form surfaces is combined with a hierarchy of meshes to form the basis of an interactive sculpting environment. The environment of...

Free-form skeleton-driven mesh deformations
In this paper, we propose a new scheme for free-form skeletondriven global mesh deformations. First a Voronoi-based skeletal mesh is extracted from a given original mesh. Next the...

Rendering Parametric Surfaces in Pen and Ink
This paper presents new algorithms and techniques for rendering parametric free-form surfaces in pen and ink. In particular, we introduce the idea of "controlled-density hatc...
