This paper proposes an interactive texture design method to obtain adequate texture patterns for 3D computer graphics shapes. Texture mapping is widely used to improve the visual richness of surface appearances. Designing texture patterns can be a problem to search an adequate pattern for the 3D shapes in the scene physically and psychologically. So it is required to supply intuitive and simple method...
This paper introduces an interactive method to design intuitive and simple surface appearance of 3D computer graphics shapes. Texture mapping is widely used to improve the visual richness of 3D surfaces.

3 dimensional computer graphics (3DCG) becomes an easily accessible technology for general public. Average PC users can design and embed high quality 3DCG images and animations in their work. They must, however, study text books and related web pages with captured 2D images for understanding 3DCG theories and graphics programming to become a good designer. They must also master complex 3D operations...
Many companies employ line production system (LPS) for producing their products in large volume. The design and installation of LPS takes enormous amount of time and costs. If any fatal troubles become obvious after the line installation, they cause heavy monetary and temporal damages to the companies. Whereas discovering any trouble spots during design phase is a crucial challenge, the advanced detection...
