PURPOSE: A three dimensional preprocessing method for ray trace is provided to perform efficient analysis without performing repetitive pre-processing according to the change of transmission point change. CONSTITUTION: A standard structure is set up. The other structure is found. A corresponding structure is stored in a standard structure(100). The corresponding structure having the side which does not seen eliminates. Distance to the stored structures is measured from the standard structure. The stored structures locating about the standard point are eliminated based on the standard structure. The travel route of the light ray is calculated between structures(200).
