XGen: Arbitrary Primitive Generator
An arbitrary primitive generator that populates primitives (grass, leaves, fur) across large pieces of geometry (ground, trees, monster) in a controllable manner.

Mesh Modeling With Curve Analogies
The expressive power of modeling by analogy applied to meshes. In this sketch, analogies are applied to families of curves on an object's surface, and the filtered curves drive a transformation of the object.

Tile Representation of Subdivision Surfaces
A method to split subdivision surfaces into tiles for texturing and rendering. Each tile maintains surface continuity but it is represented as a separate piece of geometry.

"Knot Insertion" on Subdivision Surfaces
A technique that allows modelers to locally increase resolution of a subdivision surface mesh without changing its limit surface or using hierarchical descriptions.

Fair and Robust Circle Splines
A blending scheme using circular arcs produces good-looking, smooth curves that have many properties of the globally optimal Minimum Variation Curves (MVC) but achieves this with local support.
