recast.build();

var nPt = recast.findNearestPoint(0,0,0,2.0,2.0,2.0);
console.log('FindNearestPoint result:');

recast.update(0);

recast.clearAllTempObstacles();
recast.update(0);

var ranPt1 = recast.findRandomPoint();

var ranPt2 = recast.findRandomPoint();

var path1 = recast.findPath(ranPt1.x,ranPt1.y,ranPt1.z,ranPt2.x,ranPt2.y,ranPt2.z,1000);
console.dir(path1);
