Computational Geometry Algorithms in C++

From video games and robotics to CAD software and geographic information systems, computational geometry forms the backbone of modern spatial applications. Understanding how to represent shapes, compute intersections, and partition space efficiently is crucial for solving complex real-world programming challenges. This text-based course guides you from foundational mathematical concepts to implementing complex spatial algorithms in C++. You will transition from basic vector arithmetic to advanced data structures, learning how to write clean, efficient, and numerically stable geometric code. By exploring the core theory alongside clear code implementations, you will develop the spatial reasoning skills required to tackle advanced software engineering problems. What you'll learn: - Understand fundamental linear algebra concepts, including vector operations, matrix transformations, and coordinate systems. - Implement robust geometric primitives and handle floating-point precision issues using modern C++ practices. - Compute spatial queries, distance calculations, and intersection tests for lines, planes, and polygons. - Construct spatial partitioning data structures like KD-Trees and Range Trees for efficient range searching. - Apply classical geometric algorithms, including sweep-line techniques, convex hulls, and polygon triangulation. - Practice structured problem-solving by translating mathematical proofs into clean, modular C++ code. The curriculum starts with essential mathematical definitions and geometric representations before moving into spatial data structures and advanced algorithms. Each concept is explained through clear written explanations and structured C++ code implementations that you can study at your own pace. This course is designed for software engineers, game developers, and computer science students who want to learn geometric programming. A basic understanding of C++ syntax is helpful, but no prior experience with computational geometry or advanced mathematics is required.
