From Dense Grids to Clean Perimeters: Extracting Shapes with Greedy Geometry – Tiled and JavaScript example

This technical article explains how to convert dense, cell-based binary grids into optimized geometric shapes by using greedy rectangle merging and perimeter extraction algorithms. It details the process of eliminating internal edges to obtain a clean external boundary, complete with a practical JavaScript example for visualization and implementation in game development or graphics programming.
