On June 27, a study session organized by the Technical Sub-committee was held in Suidobashi, Tokyo. Since the Technical Sub-committee focuses on the effective utilization of 3D as a theme for fiscal 2013, the theme of this study session was "Case examples of utilization of 3D and the latest 3D technologies". Experts in each field gave three lectures; 1)some trial utilization of 3D in the classroom, 2)current situations of much-talked-about 3D printers whose sales are expected to grow as a new form of 3D data utilization, 3)the latest trend of MPEG standards focusing on handling 3D and a next generation TV. In addition, Mr. Seitaro Shimizu, photographer, who has been working on 3D works over the years introduced his 3D works and talked about the current situations of the 3D photo market.
50 people, 31 companies participated in this study session.

3D images have characteristics which can directly express depth, concavity and convexity. We have been working on research which examines how we can achieve effects in terms of education and learning by utilizing these advantages and by using 3D images. This time we prepared experimental 3D educational materials for social studies about the Tumulus period for sixth-graders and conducted an experimental lesson. Actual scenes in the class and the results we acquired will be introduced together with 3D images used for the class.

Marubeni Information Systems Co., Ltd. has a history as a sales agency in Japan of Stratasys which is a manufacturer with a world leading market share of high performance 3D printers for professional use in the United States. From such a standpoint, what "3D printers" which have been recently attracting attention are, what they can produce, how they can be used, the trends in Europe and the United States which are leading the utilization of 3D printers, current situations and expectations and challenges in the future will be introduced through easy-to-understand, broad-based explanations.

25 years have passed since 1988 when a conference for standardization of MPEG-1 started. Originally, scattering establishment of numerous digital video systems was a concern in the course of advancement of digitalization of video and the mission of MPEG was the standardization of the system. Currently, technical factors which relate to MPEG standards have become extremely varied including graphics, Web, and streaming delivery. Therefore, systems of standards which are examined and stipulated by the MPEG standardization committee have also become varied. Focusing on the field of 3D and a next generation TV which have been attracting a great deal of attention from 3DC members, the whole picture of the MPEG standards system which covers various fields will be explained in a straightforward manner.

This year marks the 40th year of my activities as a photographer and 20 years have passed since I started working on 3D photography. In addition to exhibiting and presenting a part of my 3D photos and videos which have been taken for commercial purposes, I will explain about the current situations of the 3D photo market where I have been challenging the use of 3D as a new expression as well as various business methods by using 3D. A part of AR (augmented reality) and 3D photos of images of Buddha I took when I produced a project completed during the first half of this year will also be presented. They express a World Heritage site in Kyoto, Toji Temple, which owns many images of Buddha that are named as national treasures.
