    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.

    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.

    This paper aims to study the location of sound sources when playing immersive sound using multiple speaker systems in a live performance environment. In particular, this performance designated the visually impaired as the audience. Therefore, the layout design of the sound source was produced by applying immersive technology so that the audience can fully enjoy and immerse in the performance. The construction of an immersive sound system by installing a number of additional speakers in the existing grand theater performance hall and the effective delivery of immersive sound to the audience are intended in this study. In order to apply the immersive sound technology, an acoustic environment that can provide immersion to the audience by studying the process of selecting and installing the most efficient system and producing sound based on the theoretical background was established. Through the experiment, the results of the directionality of implementing the location of the immersive sound source using multiple speaker systems are summarized by the location of the sound sources. As a result, the sound source can be positioned anywhere in space, such as outside the installation location of the speaker or inside the listening seat, but it is difficult to recognize the exact location according to the direction. However, due to the characteristics of the plane wave that allows multiple listeners to perceive the same direction of the sound source, the direction of the sound source was the same in all seats of the listening seat.
