Abstract: Provided is an environment which enables a user to implement 3D space design on a computer accessible to a server computer via a network. The server computer includes a layout design program which is operable on a screen activated by a browser of the client computer to enable the user to implement space design of a layout in the terms of a 2D image, an object database which stores object data used for layout design for retrieval and extraction, and a 3D display program which is operable on the browser screen of the client computer to display the designed space in the terms of a 3D image. The client computer is equipped with the browser capable of executing programs of the layout design program and the 3D display program. Upon receiving the layout design program and the 3D display program from the server computer via the network, the programs of the layout design program and the 3D display program are executable on the browser screen.

Abstract: A housing-related commodity sales support system provides information regarding a housing-related commodity to a computer of a prospective purchaser via a network system. The system includes a database which stores housing display data, including information regarding a layout of the housing. A browser provider provides the computer of the prospective purchaser with a browser that enables the prospective purchaser to see a three-dimensional image of the housing on the computer in accordance with the database. The browser includes at least a first display performing section that enables a three-dimensional display of an interior of the housing, and a second display performing section that enables the prospective purchaser to move a viewpoint location from which the interior of the housing is seen, and to change a view of the interior of the housing in accordance with a movement of the viewpoint location.

Abstract: The inventive system includes a database for storing housing display data including layout information of a housing such as a real estate object, an interior display data including information regarding interior of the housing, and furniture display data including configuration information regarding furniture to be arranged in the housing. The inner space of the housing is displayable as a virtual space on the terminal of a computer of a prospective purchaser based on each of the data. The system provides a browser equipped with a manipulating menu with which a user manipulates the viewpoint or location of viewing in the virtual space. The system provides the user with each of the data via the Internet or its equivalent.
