Efficiently updating constrained delaunay triangulations

Rated 3.86/5 based on 609 customer reviews

The following papers include theoretical treatments of Delaunay refinement and discussions of the implementation details of my two-dimensional mesh generator and Delaunay triangulator, Triangle, and my three-dimensional mesh generator and Delaunay tetrahedralizer, Pyramid.

See the Triangle page for information about what Triangle can do, or to obtain the C source code.

The two-dimensional portion of this paper is superseded by the improved writing in “Delaunay Refinement Algorithms for Triangular Mesh Generation,” above.

The three-dimensional portion is still found only here.

This is the first one to read if you want to implement a triangular Delaunay refinement mesh generator.
