The surface of many industrial products may have geometries composed both of base shape and surface detail. From the design point of view, it is efficient to design the base shape and surface detail independently, and then to integrate the surface detail with the base shape surface for obtaining the surface-detail-integrated shape. In this paper, to realize a flexible and efficient mesh modeling for the surface-detail-integrated shape, we propose a method that integrates the surface detail with the base shape using parameterization. In our method, the user can simply design the surface-detail-integrated shape by specifying the references of integration for the base shape and surface detail, which makc positional and directional correspondence between both shapes. Surface detail integration is automatically done so as to satisfy the geometric constraints of the surface detail on the integrated shape based on successive expansion and local modification of parameterization. Finally, we demonstrate our method with several examples and evaluate the accuracy of integration, and discuss the approach which can improve the precision of surface detail integration.
