PROBLEM TO BE SOLVED: To realize walk through similar to actually walking around the outside of a building and its neighboring environment by displaying the building and its neighboring environment by a computer graphic (CG) picture as still and moving pictures and instructing the direction, the speed, etc., of advance. SOLUTION: Three-dimensional shape data concerning the building Z1 and that concerning the neighboring environments Z2 and Z3, etc., of the building Z1 are prepared by each CAD system in advance. After synthesizing these three-dimensional shape data concerning the building Z1 and the neighboring environments, the position of eyes to be the reference of CG picture preparation is stopped or moved in a desired direction with respect to a three-dimensional model obtained by synthesizing according to an operator's input operation to generate data for the CG picture corresponding to the CG picture expressing a state obtained by looking at the building Z1 and/or its neighboring environment from the position of eyes. Then the CG picture expressing the building Z1 and/or its neighboring environment based on this data for the CG picture is displayed as still-moving pictures. |
