The Unified Modeling Language (UML) is a natural candidate for user interface (UI) modelling since it is the standard notation for object oriented modelling of applications. However, it is by no means clear how to model UIs using UML. This paper presents a user interface modelling case study using UML. This case study identifies some aspects of UIs that cannot be modelled using UML notation, an...

Feature is a fundamental design unit in modern solid modeling systems, and this makes a well defined feature interface a matter of concernment in the component-based distributed modeling environment. This paper introduces a feature-based modeling service framework and proposes an interface model of feature-based modeling service toward such a modeling environment, including the support of remot...

As 3-D modeling applications transition from engineering environments into the hands of artists, designers, and the consumer market, there is an increasing demand for more intuitive interfaces. In response, 3D modeling and interface design communities have begun to develop systems based on traditional artistic techniques, particularly sketching. Collectively this growing field of research has c...

this paper concerns with the modeling and construction of a fifth order method for two dimensional acoustic wave equation in heterogenous media. the method is based on a standard discretization of the problem on smooth regions and a nonstandard method for nonsmooth regions.the construction of the nonstandard method is based on the special treatment of the interface using suitable jump condition...

This paper presents a novel interface for 3D modeling in augmented reality, aiming at developing a form gradually in the early phase of a product design process. Previous VR/AR based modeling systems have focused largely on geometrical algorithms and system performance issues. From a designers’ perspective, this study analyzed the conventional form creating processes and developed a more intuit...

Today’s geometric modeling tools are usually controlled by the mouse and keyboard. 3dmodeling operations are often constrained to planes or lines to make modeling easier. New augmented reality devices promise new classes of applications with natural 3d user interfaces. This paper deals with a new method that enables users to model 3d shapes directly with their fingers. It is implemented in Arti...
