PURPOSE:To efficiently specify eye sight information when the scenery simulation of a building, etc., generated by a three-dimensional CAD system is executed by the three-dimensional CG system by patterning the movement of a view point and a gaze point. CONSTITUTION:The coordinate specification of the view point and gaze point, i.e., the specification of eye sight information is patterned by combining basic specifying methods. For the purpose, a pattern registration processing part 31 wherein pattern data (2) on plural order combinations of processings for the rotation of the view point, the rotation of the gaze point, and the forward and backward movement of the view point are registered and an eye sight edition processing selection part 32 which selects necessary process from a gaze point calculation part 35 on the basis of the registered combination pattern data (2) are provided in an eye sight editing device 3 in the three-dimensional CG system. Then the registered combination pattern data (2) are read out and the eye sight editing that the pattern data (2) indicate is selected to alter eye sight information. |
