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.
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.
- Graph operations: traversal, graph partitioning.
- Metric operations (area, volume, curvature ...).
- Triangle strips generation for fast rendering.
