Snakes: Active contour models
TLDR
A snake is an energy-minimizing spline guided by external constraint forces and influenced by image forces that pull it toward features such as lines and edges. Expand

Analyzing Oriented Patterns
TLDR
A method for the local estimation of anisotropy and a method for combining the estimates to construct a flow coordinate system. Expand

Spacetime constraints
TLDR
We present a physically-based approach to character animation in which coordinated, active motion is created automatically by specifying: What the character has to do, for instance “jump from here to there.” How the motion should be performed. Expand

Hierarchical Z-buffer visibility
TLDR
An ideal visibility algorithm should a) quickly reject most of the hidden geometry in a model and b) exploit the spatial and temporal coherence of the images being generated. Ray casting with spatial subdivision does well on criterion (a), but poorly on criterion b). Expand

Efficient, fair interpolation using Catmull-Clark surfaces
TLDR
We describe an e‐cient method for constructing a smooth surface that interpolates the vertices of a mesh of arbitrary topological type that minimizes a smoothness or \fairness" measure. Expand

Subdivision surfaces in character animation
TLDR
The creation of believable and endearing characters in computer graphics presents a number of technical challenges, including the modeling, animation and rendering of complex shapes such as heads, hands, and clothing. Expand

Rapid, stable fluid dynamics for computer graphics
TLDR
We present a new method for animating water based on a simple, rapid and stable solution of a set of partial differential equations resulting from an approximation to the shallow water equations. Expand

Untangling cloth
TLDR
This paper describes a history-free cloth collision response algorithm based on global intersection analysis of cloth meshes at each simulation step. Expand

Constraints on Deformable Models: Recovering 3D Shape and Nonrigid Motion
TLDR
We describe an extrinsic force that applies constraints derived from profiles of monocularly viewed objects and use it to exploit binocular image data to recover 3D shape and nonrigid motion. Expand

Smoothed local histogram filters
TLDR
We present an efficient and practical method for computing accurate derivatives and integrals of locally-weighted histograms over large neighborhoods. Expand
