Navigation mesh

A navigation mesh, or navmesh, is a data structure used in computer graphics, especially in video games and simulations, to help characters and agents move around a virtual environment. It defines walkable areas and obstacles, allowing characters to find efficient paths to their destinations. Think of it as a map that highlights where a character can go, making navigation realistic and dynamic. Instead of calculating paths through complex geometry, the navigation mesh simplifies this by breaking the environment into polygons, ensuring characters avoid barriers while traveling smoothly through the virtual space.
