Description: A navigation mesh is a structure used in computer graphics and video game development to define navigable areas for characters controlled by artificial intelligence (AI). Essentially, this mesh acts as a map that guides characters in a three-dimensional environment, allowing them to move efficiently and realistically. Navigation meshes are constructed from the geometry of the game environment, where walkable surfaces are identified and marked, as well as obstacles that must be avoided. This enables AI characters to plan their movements, choose optimal routes, and respond dynamically to changes in the environment. In various graphics engines, the creation of these meshes is often an automated process that simplifies development, allowing designers to focus on other aspects of the game. The navigation mesh not only enhances gameplay by making characters behave more naturally but also optimizes game performance by reducing the computational load required to determine movement paths in real-time.
