Title:

THREE-DIMENSIONAL PRESENTATION OF STRUCTURE

Document Type and Number:

WIPO Patent Application WO/1989/000737

Kind Code:

A1

Abstract:

In a three-dimensional presentation method of a structure, a rectangular parallelepiped (RP) having the sides (LX, LY, LZ) equal to the respective distances between the nearest and farthest positions of a structure (SML) along the three axes from the origin is constituted of a number of identical cubes (UC), and the structure is expressed by the data that indicate whether the unit cubes constitute the structure (SML) or not. The individual unit cubes constituting the structure (SML) are successively drawn starting from the ones that are seen from the observer. The planes of unit cubes overlapped on the planes of the unit cubes that are drawn already are not drawn, and only those planes that are visually located near the observer are drawn to provide a perspective view of a three-dimensional structure (SML).
