Computational Geometry is a branch of mathematics that deals with the solution of geometric problems that emerge in a variety of applications such as geographic information systems, robotics, and computer graphics, among others. Computational Geometry is covered in depth in this Handbook, which provides an overview of key concepts and results in the field. It can be used as a reference and study aid for those interested in the topic. Not only are the most cutting-edge methods and answers given, but also several alternative approaches to issue solving and problem solving strategies.
