About:
Gts (GNU Triangulated Surface) is a C library designed for 3D surface manipulation and processing. It provides a robust set of tools for creating, refining, and performing boolean operations on triangular meshes. Its main value proposition is offering a reliable, open-source foundation for computational geometry tasks in scientific and engineering applications.

Key Features:

3D surface mesh manipulation and editing
Boolean operations (union, intersection, difference)
Surface refinement and simplification algorithms
Intersections and ray tracing capabilities
C library with command-line utilities

Use Cases:

3D modeling and computational geometry research
Processing and optimizing triangular meshes for CAD or simulation
Geographic Information System (GIS) data surface generation

Alternatives:

CGAL – CGAL is a much larger, comprehensive C++ library with a steeper learning curve, whereas Gts is lightweight and C-based.
OpenSCAD – OpenSCAD focuses on constructive solid geometry (CSG) for modeling, while Gts provides lower-level mesh manipulation primitives.
