             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.",
