Another response made me realize this can be coded a little more
concisely.  If I have two boxes b1 and b2, the function can be:

boolean intersect( b1, b2 )
{
   if ( (b1.max.x < b2.min.x) || (b1.min.x > b2.max.x) return FALSE;
   if ( (b1.max.y < b2.min.y) || (b1.min.y > b2.max.y) return FALSE;
   if ( (b1.max.z < b2.min.z) || (b1.min.z > b2.max.z) return FALSE;
   return TRUE;
}
