Polygon Drawing and Filling Algorithms

This article presents the implementation process of polygon drawing and filling algorithms using MATLAB. The development requires meticulous planning and analysis to ensure successful polygon rendering and color filling operations. During implementation, key technical details must be addressed, including coordinate calculation for polygon vertices and color filling techniques using MATLAB's graphics functions. The process utilizes MATLAB's built-in functions like patch() for polygon creation and fill() for applying colors, while also demonstrating how to handle vertex ordering and boundary detection algorithms. This implementation demands certain technical knowledge and programming experience, but once mastered, users can efficiently draw and fill any polygon configuration with precision. Learning these techniques is particularly valuable for professionals working with computational geometry, computer graphics applications, or data visualization projects where polygon manipulation is essential. The code examples illustrate practical approaches for handling convex and concave polygons, including edge table processing for scan-line filling algorithms and coordinate transformation methods.
