bool NL3D::CPatchUVLocator::sameEdgeOrder (    )  const [inline]
 

return true only if the 2 edges have same number of tiles.

bind 1/X case: return true only if ALL the adjacents patchs respect this rule. So you are sure that for all the src patch, one tile has exaclty one neighbor tile near him.
