  ok, i have a bounding box made of 4 points, bbox[0] to bbox[3] i need to know if a poly is inside of those points, then determine what the poly is, whether it be terrain, a wall, or projectile.thx in advance.dirtypope  
  You need only the Min and Max x,y & z values from every cube. Then check every object in your engine to see if it is > Min.x and < Min.x etc.
