The Computational Geometry Algorithms Library is a collaborative |
7 |
open source library containing: |
8 |
* the Kernel with geometric primitives such as points, vectors, |
9 |
lines, predicates for testing things such as relative positions of |
10 |
points, and operations such as intersections and distance calculation. |
11 |
* the Basic Library which is a collection of standard data |
12 |
structures and geometric algorithms, such as convex hull in 2D/3D, |
13 |
(Delaunay) triangulation in 2D/3D, planar map, polyhedron, smallest |
14 |
enclosing circle, and multidimensional query structures. |
15 |
* the Support Library which offers interfaces to other packages, |
16 |
e.g., for visualisation, and I/O, and other support facilities. |
