Addendum: I have been using things of the format:
  #if (((vectorArray[i].x <= vectorB.x) & (vectorArray[i].x >= vectorA.x)) & 
((vectorArray[i].y <= vectorB.y) & (vectorArray[i].y >= vectorA.y)) & 
((vectorArray[i].z <= vectorB.z) & (vectorArray[i].z >= vectorA.z)))  etc...

Where vector A and B are min/max extents of object being tested 
against...I'm just not sure that this is the best way...
