recastnavigation

Why we included this project

Recast is the navigation-mesh library most game engines quietly build on. It bakes arbitrary level geometry into a walkable navmesh through a voxel rasterization pass, and the Detour module handles the runtime side: pathfinding, navmesh queries, and streaming tiles for large open worlds. DetourCrowd layers on agent movement and collision avoidance, which is what keeps a crowd of units moving naturally instead of freezing or jittering. The whole thing is dependency-free C++98, so it drops into an engine or a custom codebase without dragging in a build system, and the bundled RecastDemo doubles as a working reference for both baking meshes and testing paths. If you are wiring navigation into Unity, Unreal, Godot, or your own engine, this is the most proven place to start.
