Using Octrees and A* for Efficient Pathfinding

Octrees in Unity offer an efficient way to optimize large 3D spaces, and in this video, we dive into implementing an Octree and using it in combination with the A* algorithm for pathfinding. We'll show how Octrees help divide space to manage objects and obstacles, making A* pathfinding more efficient in complex 3D environments. You’ll learn how to avoid obstacles, calculate the best routes, and leverage the power of Octrees to improve performance. Whether you're building a large open world or a detailed simulation, this tutorial will help you make the most of your spatial data in Unity.
