Tutorials

CGAL provides a large number of data structures and algorithms dedicated to various applications.

Most of these data structures and algorithms can be combined to achieve extensive and complex geometric tasks. The tutorials aim at providing help and ideas on how to use CGAL beyond the simple examples of the User Manual.

List of Available Tutorials

• Hello World presents you some short example programs to get a first idea for the look and feel of a program that uses CGAL. We introduce the notion of the kernel which defines geometric primitives, the notion of traits classes which define what primitives are used by a geometric algorithm, the notions of concept and model.
• Surface Reconstruction from Point Clouds
• GIS (Geographic Information System)

Package Examples

Each CGAL package comes with a set of commented examples that illustrate basic features of the package. See for example Section Examples of the User Manual of the package 3D Triangulations.
