Snakes: Active contour models
TLDR
This work uses snakes for interactive interpretation, in which user-imposed constraint forces guide the snake near features of interest, and uses scale-space continuation to enlarge the capture region surrounding a feature.
Analyzing Oriented Patterns
Efficient, fair interpolation using Catmull-Clark surfaces
TLDR
An e‐cient method for constructing a smooth surface that interpolates the vertices of a mesh of arbitrary topological type that improves on existing interpolation techniques in that it is fast, robust and general.
Hierarchical Z-buffer visibility
TLDR
A hierarchical Z-buffer scan-conversion algorithm that uses two hierarchical data structures, an object-space octree and an image-space Z pyramid, to accelerate scan conversion and is well suited to models with high depth complexity.
Spacetime constraints
TLDR
This work presents as examples a Luxo lamp performing a variety of coordinated motions that conform to such principles of traditional animation as anticipation, squash-and-stretch, follow-through, and timing.
Subdivision surfaces in character animation
TLDR
A practical technique for constructing provably smooth variable-radius fillets and blends and methods for using subdivision surfaces in clothing simulation including a new algorithm for efficient collision detection are devised.
Rapid, stable fluid dynamics for computer graphics
TLDR
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, which can generate the effects of wave refraction with depth.
Untangling cloth
TLDR
A history-free cloth collision response algorithm based on global intersection analysis of cloth meshes at each simulation step, called collision flypapering, that resolves tangles that arise during pinching as soon as the surrounding geometry permits, and also resolves tangled initial conditions.
Reaction-diffusion textures
TLDR
This work presents a method for texture synthesis based on the simulation of a process of local nonlinear interaction, called reaction-diffusion, which has been proposed as a model of biological pattern formation and adapts it to the needs of computer graphics.
