Demand for complicated objects in digital contents has been rising as the quality of 3D computer graphics improved. Decorative modeling is useful for enhancing the appearance of objects, however, it is also a difficult task that requires knowledge of decorative patterns. We propose a support method for 3D geometric modeling of ancient Greek and Roman style decor for use in digital contents. Our approach is based on modeling by parts synthesis. These decor styles are characterized by organic shapes of foliage and scrolls; thus, we classified 3,313 parts obtained from 200 pictures of foliage decorations mainly contains acanthus plant according to their shapes and positions. We then extracted 34 representative parts required for decorative design and constructed a 3D model library of these parts. The users can design their original decor by assembling them with existing geometric modeling tools. We found the parts can be divided broadly into two categories: fundamental parts that have curves characterize the scroll pattern and the decoration parts that decorates the curves. Efficient geometric modeling of the European style decor can be achieved by arranging fundamental parts first then decoration parts. Experimental results demonstrate that the user can significantly reduce modeling time decor using our 3D model library.

To promote UGC (User Generated Content) on the Internet, several techniques have been developed to allow users to create CG animations only by writing scripts quickly. TVML (TV program Making Language) is a technology capable of obtaining TV-program-like CG animation by writing text scripts. This paper aims to propose an application that automatically converts blog posts into CG animations with news show format with the aid of TVML. The process is: 1) to fetch HTML of the blog posts and perform web scraping and natural language processing to obtain summarized speech texts, 2) to automatically give a show format received from the analysis of professional TV program to get TVML script, 3) to apply the CG character and artworks, etc. that fit the blog content to obtain the final CG animation. In this paper, we describe the process and explain the application that we developed based on the method, and explain the evaluations of the outcome produced from the blog posts.

Currently, children spend considerable time playing video games and watching videos, which affects their communication skills and speaking time. Previous studies have shown that visual art education helps young children to communicate their ideas. In addition, visual thinking programs improve the understanding of visual images and result in considerable improvement in mathematics, reading, and social emotional learning. In this study, we propose 2D interactive animation systems for children at different educational stages that can be used in visual art education programs. The proposed systems use a crowd simulation-based animation mechanism that does not require complicated keyframing or large amounts of hand drawings. Children have different abilities; thus, we developed two systems, one with minimum functions with voice input and the other with additional functions based on path-drawing input. The proposed systems were verified on primary school and kindergarten students. We allowed the students to use our systems freely by drawing anything and creating stories using their hand drawings. We observed that the students communicated with each other when they showed and talked about their work. The positive feedback obtained from discussion with teachers indicates that the proposed systems encourage communication between children.
