 Recast is state of the art navigation mesh construction toolset for games.
 .
  * It is automatic, which means that you can throw any level geometry at it and
    you will get robust mesh out
  * It is fast which means swift turnaround times for level designers
  * It is open source so it comes with full source and you can customize it to
 your heart's content.
 .
 The Recast process starts with constructing a voxel mold from a level
 geometry and then casting a navigation mesh over it. The process consists
 of three steps, building the voxel mold, partitioning the mold into simple
 regions, peeling off the regions as simple polygons
