A JavaScript library providing navigation mesh pathfinding for three.js, based on PatrolJS. It computes paths across 3D nav meshes, supports multiple zones, and clamps movement vectors for FPS-style controls.

Use cases

• find paths for AI agents on a 3D navmesh in a three.js scene
• navigate NPCs around obstacles in a browser game
• clamp player movement vectors to a navigation mesh in FPS controls
• load a navmesh exported from Blender or Recast as glTF and query paths
• support multiple navigation zones in a WebVR or 3D app

When to choose

• you already have or can build a navmesh (Blender, Recast) and use three.js
• you need lightweight A* pathfinding on triangulated 3D meshes in the browser
• you want an MIT-licensed, well-maintained alternative to waypoint-based navigation

When to avoid

• you need navmesh generation or Recast's native binary file formats
• your project is not built on three.js
• you need server-side pathfinding for large-scale game backends
