# Introduction
As the field of computer science continues to evolve at an unprecedented pace, computational geometry has emerged as a crucial subfield with a wide range of applications. This article aims to delve into the intricacies of computational geometry, providing an overview of its fundamental concepts, exploring its historical roots, discussing its modern applications, and highlighting its impact on various industries.
# Foundations of Computational Geometry
Computational geometry is concerned with the design and analysis of algorithms for solving geometric problems. These problems often involve the manipulation and processing of geometric objects such as points, lines, curves, and polygons. The field draws heavily from mathematical disciplines such as geometry, linear algebra, and graph theory to develop efficient algorithms that can solve complex geometric problems.
# Historical Perspective
The roots of computational geometry can be traced back to ancient civilizations, where geometric problems were solved manually using geometric constructions and methods. However, the formal study of computational geometry began to take shape in the late 1960s and early 1970s with the advent of computers and the increasing need for efficient algorithms to solve geometric problems.
One of the earliest breakthroughs in computational geometry was the development of the Graham scan algorithm by Ronald Graham in 1972. This algorithm efficiently computes the convex hull of a set of points in the plane, a fundamental problem in computational geometry. This paved the way for further advancements in the field, leading to the establishment of computational geometry as a distinct subfield within computer science.
