Navigation mesh for Bevy using Polyanya.
Check out the WASM demos
Loading a mesh from a gLTF file, then building a NavMesh from it and using it for getting paths. See gltf.rs and NavMesh::from_bevy_mesh.
Spawn entities marked as obstacles, create the NavMesh live from them. See auto_navmesh_aabb and NavMeshUpdaterPlugin.
Parameters for NavMesh generation
Pathfinding:
- Compromise-free Pathfinding on a Navigation Mesh: Fast and optimal path finding on a generalized navmesh
NavMesh building:
- Line Generalisation by Repeated Elimination of Points: Geometry simplification while keeping the general shape
- Constrained Delaunay Triangulation: Building a tri-mesh from edges
