GTS-GNU Triangulated Surface Library

GTS stands for the GNU Triangulated Surface Library. It is an Open Source
Free Software Library intended to provide a set of useful functions to
deal with 3D surfaces meshed with interconnected triangles. The source
code is available free of charge under the Free Software LGPL license. The code is written entirely in C with an object-oriented approach based
mostly on the design of GTK+. Careful attention is paid to performance
related issues as the initial goal of GTS is to provide a simple and
efficient library to scientists dealing with 3D computational surface
meshes.

A brief summary of its main features:

Simple object-oriented structure giving easy access to topological
properties.

2D dynamic Delaunay and constrained Delaunay triangulations.

Robust geometric predicates (orientation, in circle) using fast adaptive
floating point arithmetic (adapted from the fine work of Jonathan R.
Shewchuk).

Robust set operations on surfaces (union, intersection, difference).

Surface refinement and coarsening (multiresolution models).

Dynamic view-independent continuous level-of-detail.

Preliminary support for view-dependent level-of-detail.

Bounding-boxes trees and Kd-trees for efficient point location and
collision/intersection detection.

Metric operations (area, volume, curvature ...).

Triangle strips generation for fast rendering.
