  3. Heuristic_path_planners

    Collection of classes and functions to allow 2D/3D path generation with heuristic algorithms such as A*, Theta* and LazyTheta* and ROS Interfaces

  4. namigator

    An intelligent navigation API for World of Warcraft Alpha, Vanilla, TBC and WotLK

  5. DonAINavigation

    This plugin provides a 3D dynamic pathfinding system for use with Unreal Engine 4. It's primarly designed for Flying AI creatures based in dynamic or procedural worlds that need to solve complex pathfinding tasks.

  6. MT-RRT

    General purpose library for multithreaded Rapidly Random exploring Trees

  7. Mazes

    C++ Maze Visualizer supporting orthogonal, hexagonal, and Voronoi diagram grids. (by Kirkezz)

  8. Doryen

    Doryen based in Libtcod 1.5.1 - Refactoring struct and clear code, deleted the old C code and added new features and algorithms. The objective is a small 2D rendering engine (based in grid or tiles). It is written in an effort to create an engine being as lightweight and conceptually clean as possible.

  9. AStarSearch

    A Simple Implementation of A Star Search Algorithm

  10. astar_pathfinder_grid_2d

    Single header library for path finding on 2D grids with A* algorithm. Includes a stable and a fast path finders.
