The adaptive model point location represents an adaptive placement point location set in the adaptive metric conventional model. The rectangle family represents an adaptive model in which the plane figure is a rectangle. The family of oriented rectangles represents an adaptive model whose plan view is rectangular, and has a model specifying the direction of placement, such as parking space, fire hydrant. The family of rectangles without direction represents an adaptive model in which the plane figure is rectangular, but does not have a model specifying the direction of placement, such as a rectangular luminaire, a rectangular decorative post. The connecting line of the short sides of the rectangular outline represents the line segment connecting the geometric midpoint of the rectangular outline and the midpoint of the short side of the rectangular outline. The direction determination line represents a line segment intersecting a line connecting the short sides of the right rectangle in the rectangle outline when the rectangle family is placed right (i.e., the long side is parallel to the X axis and the short side is parallel to the Y axis), and the line segment is located within the rectangle outline and does not intersect a line connecting the short sides of the left rectangle in the rectangle outline. A list represents a sequence of ordered variable elements, each element or item in the list is assigned a number or index, the first item index is 0, the second item index is 1, and so on. For convenience of indicating a list with a bracket and a comma separating the list, for example, the list [ a, P ] indicates that the item value with an index value of 0 in the list is a and the item value with an index value of 1 is P. A tertiary list is defined as a list that is tertiary if the corresponding item in the list is a single list. For example, a three-level list [ [ A, P ], [ A, D ] ] indicates that the item value with index value 0 in the list is list [ A, P ], and the item value with index value 1 is list [ A, D ].

and fifthly, carrying out tolerance judgment on all points in the polygon midpoint list through the point. And then, according to each point position in the polygon midpoint duplicate removal list, utilizing a list, first IndexOf nodes to obtain the first appearing index of each item in the polygon midpoint list, and sequentially operating to obtain an index value list.

Index value list part content: [0,1,2,3,4,5,6,7,8,9,10 ];

and step six, firstly, sequentially deriving graphs corresponding to index values in a polygonal graph list through index values in an index value list by virtue of a List.
