The Strange Complexity of Constrained Delaunay Triangulation
The problem of determining whether a polyhedron has a constrained Delaunay tetrahedralization is NP-complete. However, if no five vertices of the polyhedron lie on a common spher...

Characterisation and generalisation of cartographic lines using Delaunay triangulation
A method is presented for generalising cartographic lines using an approach based on determination of their structure. Constrained Delaunay triangulation is used to construct a ske...

Delaunay Meshing of Isosurfaces
We present an isosurface meshing algorithm, DELISO, based on the Delaunay refinement paradigm. This paradigm has been successfully applied to mesh a variety of domains with guara...
