Foundations of Geometric Algorithms

Spatial data powers everything from modern computer graphics and robotics to geographic information systems (GIS). But how do computers actually understand, process, and manipulate shapes, lines, and polygons? This text-based course introduces you to the core logic behind computational geometry. You will build a strong foundation in the algorithms used to process spatial data, learning how to translate abstract geometric concepts into efficient programming logic. What you'll learn: - Understand foundational geometric concepts, including point location, line intersections, and polygon properties. - Learn the logic behind convex hull algorithms and how they efficiently enclose spatial datasets. - Apply modern spatial data structures, such as KD-trees and Quadtrees, commonly used in spatial databases and game engines. - Analyze algorithms for collision detection and proximity queries in two-dimensional space. - Practice evaluating the computational efficiency and edge cases of different geometric approaches. The course begins with essential terminology and basic coordinate geometry definitions before progressing into more complex algorithms and modern spatial indexing techniques. Through clear written explanations and text-based code logic, you will explore how theoretical geometry becomes practical computation. This course is designed for beginners, computer science students, and software developers looking to understand computational geometry without requiring prior experience in the field.
