Modified Subdivision Surfaces With Continuous Curvature
A simple algorithm that modifies Catmull Clark surfaces near extraordinary points. The modified surfaces are C2-continuous and exhibit better curvature behavior.

Edge Subdivision Schemes and the Construction of Smooth Vector Fields
An intrinsic method of generating smooth 1-forms/vector fields through edge subdivision on simplicial surfaces of arbitrary topology. The method integrates well with subdivision surfaces and has a simple and intuitive design methodology.

Streaming Computation of Delaunay Triangulations
Adding spatial finalization tags to a point stream enables fast out-of-core Delaunay triangulation. On a household laptop, this method triangulates 500 million points into a billion-triangle terrain in one hour using 100 MB memory.

Spectral Surface Quadrangulation
SSQ automatically converts triangulated surfaces into meshes composed exclusively of quadrilaterals and very few extraordinary points. It does this by extracting the Morse-Smale complex of a carefully chosen Laplacian eigenvector.
