Thomas Young, who was interviewed right here a month ago, announces that he has released an evaluation version of the PathEngine middleware pathfinding library, available at www.pathengine.com.

""PathEngine provides geometric pathfinding queries for a well specified collision model based on arbitrarily overlapping 3D ground meshes, with strong support for dynamically placed obstacles."

Apparently, the release contains an evaluation version of the PathEngine DLL, as well as the PathEngine testbed, tutorials and example applications -- documentation included! If you're in the process of developing your own game AI, be sure to check that out!
