How octree works. Octree is a tree where each internal (non-leaf) node has eight children. Each node spans a particular space area, expressed as an axis-aligned bounding box (available as Box property of TOctreeNode ). Each node also has a chosen middle point inside this box (available as MiddlePoint property of TOctreeNode class). fishing boat setup ideas
