THREE-DIMENSIONAL CAD SYSTEM PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a technology for allowing building equipment CAD drawing which has a three-dimensional shape based on three-dimensional data and is two-dimensionally displayed to be easily displayed to a three-dimensional CG space display device from arbitrary point of view and a line of sight direction a user desires and allowing the three-dimensional shape to be successively displayed continuously to the three-dimensional CG space display device as if the user were continuously moving in the three-dimensional CG space. SOLUTION: A CAD system program constitutes: a three-dimensional shape data storage means 12 for storing three-dimensional shape data; a polygon data reflecting means 16 for reflecting the three-dimensional shape data stored in the three-dimensional shape data storage means 12 to polygon data; and a polygon data display means 20 for displaying the polygon data to be displayed inside a three-dimensional CG space from a designated point of view position and line of sight direction.
