Parallel constrained Delaunay triangulation on the GPU
TLDR
We propose a novel GPU-based approach for computing the 2D constrained Delaunay triangulation (CDT) of a planar straight-line graph consisting of points and segments. Expand

Mesh Modification Under Local Domain Changes
TLDR
We propose algorithms to incrementally modify a mesh of a planar domain by interactively inserting and removing elements (points, segments, polygonal lines, etc.) into or from the planar Domain, keeping the quality of the mesh during the process. Expand

Combining improvement and refinement techniques: 2D Delaunay mesh adaptation under domain changes
TLDR
We propose a framework that combines improvement and Delaunay refinement techniques for incrementally adapting a refined mesh by interactively inserting and removing domain elements. Expand

Accurate Interpolation of Terrain Surfaces from Over-Sampled Grid Data
TLDR
We propose a Lepp-surface triangulation method that starts with a coarse initial triangulations of the input data, and incrementally adds data points that reduce the worst edge approximation error in the mesh. Expand

Modifying Delaunay Refined Two-Dimensional Triangular Meshes
We propose algorithms to modify a mesh of a PSLG through out the interactive addition/deletion of elements to/from the PSLG, keeping the quality of the mesh all along the process. Our algorithmsExpand

Adaptive simplification of huge sets of terrain grid data for geosciences applications
TLDR
We propose and discuss a new Lepp-surface method able to produce a small triangular approximation of huge sets of terrain grid data by using a two-goal strategy that assures both small approximation error and well-shaped 3D triangles. Expand

A Framework for Triangular Mesh Generation and Modification Processes
TLDR
In this paper we present an object-oriented framework for implementing mesh generation and mesh modification processes. Expand
Affine Coordinate-Based Parametrized Active Contours for 2D and 3D Image Segmentation
TLDR
We present a new framework for image segmentation based on parametrized active contours that allows to easily formulate region-based energies as the one proposed by Chan and Vese. Expand
