Functional Evaluation of the Solid Model Creation using 3D Direct Drawing System

3D model of computer is usually created using 3D CAD software, but 3D direct drawing method is still developing the research. In this paper, we suggest and construct the 3D direct drawing system with ARToolKit and develop the required creating methods and tools. The method is the creating solid algorithm using projective methods. The algorithm is the converting multiple surfaces into a solid. After that, the functionality of the methods and tools are evaluated using the Taguchi method (quality engineering). In addition, we investigate the optimal condition of the creating methods and tools required for modeling.
