The first image shows the light blue, lila and dark orange marked points of the table above. In my opinion these points are used to create the bounding box.
The second image gives you an overview of the packages. Every package contains the x- y- and z-coordinate of a point. In this example every point exists in duplicate, so that you can only see 8 points. These points are needed to built up the mesh (triangles) for a door.
Image number three is a fusion of the first and the second image.
