Three-dimensional computer graphics modeling system

摘要

PROBLEM TO BE SOLVED: To provide an easier three-dimensional computer graphics modeling system easy to grasp three-dimensional shape as compared to a conventional three-dimensional figure modeling system.;SOLUTION: In this system, (1) the front face of a polyhedron object is determined, (2) all vertexes and sides when viewing the polyhedron object from the front face are drawn on a drawing screen of a display, two-dimensional shape of the front face of the polyhedron object is determined, (3) depth direction information about all the vertexes when viewing it from the front face is determined, (4) the sides connecting the respective vertexes of the front face and the respective vertexes of the backside are edited, (5) and three-dimensional polyhedron figure image data are converted into two-dimensional screen coordinate system data to display a three-dimensional figure on the computer display.;COPYRIGHT: (C)2005,JPO&NCIPI
