abstract = "Simplicial meshes are extremely useful as discrete approximations
of continuous spaces in numerical simulations. In some
applications, however, meshes need to be modified over time. Mesh
update operations are often expensive and brittle, which tends to
make the numerical simulations unstable. In this paper we propose
an alternative technique for updating simplicial meshes that
undergo geometric and topological changes. We exploit the property
that a Weighted Delaunay Triangulation (WDT) can be used to
implicitly define the connectivity of a mesh. Instead of
explicitly maintaining connectivity information, we simply keep a
collection of weights associated with each vertex. This approach
allows for a simple way to merge triangulations, which we
illustrate with examples in 2D and 3D.",
