Computer Graphics Algorithms: Line and Circle Drawing

Have you ever wondered how computers actually draw a smooth line or a perfect circle on a pixelated screen? This text-based course takes you behind the scenes of computer graphics to explore the essential algorithms that power modern rendering engines. You will start with the absolute basics of coordinate systems and pixel grids, establishing a solid conceptual foundation. From there, you will learn how to translate mathematical equations into highly optimized code. By reading clear explanations and studying structured code snippets, you will understand how classic algorithms operate and how to implement them yourself. What you'll learn: - Understand the core concepts of rasterization and pixel-based coordinate systems - Implement the Digital Differential Analyzer (DDA) algorithm for line generation - Master Bresenham's Line Algorithm for fast, integer-only rendering - Apply the Midpoint Circle Algorithm to draw precise circular curves - Analyze the performance trade-offs between floating-point and integer math - Explore modern extensions like basic anti-aliasing techniques to smooth jagged edges We begin with foundational definitions of pixels and grids before moving step-by-step through each algorithm's logic, complete with written walk-throughs and implementation exercises. This course is designed for aspiring graphics programmers, game developers, and computer science students with a basic understanding of programming logic but no prior graphics experience.
