Abstract: An object of the present invention is to provide an Internet-based marketing tool that is not available in the conventional art. It includes a three-dimensional model database that stores a three-dimensional model pertaining to a target object, a viewpoint setting unit that sets a viewpoint for viewing of the target object, an image generating unit that generates an image of the target object viewed from the set viewpoint based on the three-dimensional model database, a tracking unit that tracks the set viewpoint, and an analyzing unit that performs analysis of the preferences of the user that set the viewpoint position, based on the output from the tracking unit.

Abstract: It is an object of the invention to provide a three-dimensional beauty simulation client-server system which is capable of handling a users face in a three-dimensional fashion and of providing more realistic beauty simulations. This system comprises a shop-based client that obtains and transmits three-dimensional shape data regarding a user, and a server comprising a makeup simulation unit that receives and stores the three-dimensional shape data from the shop-based client and carries out makeup simulation based on the three-dimensional shape data in response to requests from the user, and a data control unit that analyzes the users operation record and generates administrative information.
