Overview

GAMer is a Geometry-preserving Adaptive MeshER that produces high-quality simplex meshes of surfaces and volumes, given a number of different types of input data. It is built on top of two state-of-the-art mesh generators: Triangle (for 2D constrained Delaunay meshes in the plane) and Tetgen (for 3D constrained Delaunay meshes in space), combined with a collection of algorithms for generating, improving, refining, and decimating surface triangulations of imbedded interior or exterior domain surfaces. GAMer was developed primarily by Zeyun Yu in the Holst Research Group at UC San Diego. GAMer and the algorithms it employs are described in detail in:
