A data structure for a graph, which is composed by points and line segments connecting adjacent pairs of the points, respectively, of a two- or three-dimensional object comprises a set of point data of the individual points, each of the point data of the points consists of a clockwise or counter clockwise circular ordered adjacency list written in storage areas of a storage medium individually allocated to the point. The adjacency list describes a plurality of adjacent points associated with the point sequentially according to a circular adjacency order as viewed from outside of the graph with address pointers to the storage areas allocated to the adjacent points, respectively, and location pointers associated with the address pointers, respectively, to storage locations of adjacency lists of the adjacent points, respectively, where an address pointer of the point is written.

Method, computer program product and data structure for representing two- or three-dimensional object modeling

For the purpose of providing a loop chain in which light-related members can be easily attached to and detached from the loops, and do not readily fall off, and which has a good appearance from the standpoint of design, a loop is provided with an engaging tab , and a latching adapter comprising a light-related member or a latching adapter is fitted to the engaging tab.

Loop chain structure

The present invention provides a fence chain indicator enabling a single type of sheet body made of either a luminous material or a luminescent material to be attached to fence chain ring bodies of different dimensions, and also enabling this sheet body to be securely fastened. The fence chain indicator comprises a sheet body which has flexibility, is made from either a luminous material or a luminescent material, and provided with fastening portions which are opened, at the opposite ends thereof, and is constituted such that a fastening member , which is provided with engagement grooves for locking, is integrally attached to one end of the above-mentioned sheet body ; a mating portion is formed in the other end for mating with the above-mentioned fastening member ; and a through-hole of the above-mentioned fastening member is formed in approximately the center portion of the above-mentioned sheet body
