Line Drawing Algorithms in Computer Graphics with MATLAB Implementation

In this article, we explore the implementation of line drawing algorithms in computer graphics using MATLAB. We will examine several classical line drawing algorithms, including the midpoint line algorithm, and delve into their implementation approaches and roles in computer graphics. The discussion covers key algorithmic concepts such as digital differential analyzers (DDA) and Bresenham's line algorithm, explaining how these methods efficiently determine pixel positions between two endpoints while minimizing computational overhead. We will analyze the advantages and limitations of each algorithm, particularly focusing on their computational efficiency, precision, and suitability for different graphical applications. Additionally, we demonstrate practical MATLAB implementations featuring vectorized operations and optimized plotting functions, providing useful coding techniques and best practices to facilitate smoother algorithm development. The article includes code examples showing how to handle various line slopes and endpoints, with explanations of critical MATLAB functions like plot() and line() for visualization. This comprehensive guide aims to deliver valuable insights and help readers better understand and apply line drawing algorithms in computer graphics projects.
