An Augmented Reality Approach to 3D Solid Modeling and Demonstration

Abstract

This paper presents an intuitive and natural gesture-based methodology for solid modelling in the Augmented Reality (AR) environment. The framework of Client/Server (C/S) is adopted to design the AR-based computer aided design (CAD) system. The method of creating random or constraints- based points using gesture recognition is developed to support modelling. In addition, a prototype system of product 3D solid modelling has been successfully developed, we have compared it with traditional CAD systems through several basic design modeling tasks. Finally, analysis of questionnaire feedback survey shows the intuitiveness and effectiveness of the system, and user studies demonstrate the advantage of helping accomplish the product early design and creating and manipulating the 3D model in the AR environment.
