Construction of a "3D information studio" for a "3D virtual library".

“3D信息工作室”是为包括常规虚拟图书馆和博物馆功能在内的新的“3D虚拟图书馆”负责三维内容工作的框架。作为主题，我们建立了一个陶瓷艺术品和手工艺品的数字数据库。我们已经研究了它的基本功能，如创造、保存、分类和参考。此外，还考虑了向高速网络的扩展。我们的研究取得了以下成果：1.开发了一个3D内容的工作支持功能。我们开发了一个3D建模器，它可以通过应用交互式进化计算(IEC)框架来支持创建新的3D形式和动画。此外，该建模器还提供了手写自由造型的输入功能。2.彩色图像创作支持功能的开发。利用从已有内容中提取颜色信息并反映到用户色彩图像中的新技术，实现了配色方案支持工具。3.陶瓷数字数据库的构建。在对陶器进行分类和参照时，我们考察了参照物的各个方面。柴田收藏的有田陶器从照片中提取了形式和颜色信息。4.扩展到高速网络环境。我们使用大分县的一个高速质量网络--Toyo-no-kuni超网络来检验3D建模方法。为了解决网络中高负载时的丢包、通信时延等问题，还考虑了第九区。

"3D information studio" is the framework that can take charge of the 3-dimensional contents work for new "3D virtual library" including conventional virtual library and museum function. As a subject matter, we take up a digital database of ceramic artworks and handicrafts. We have studied about the essential functions, such as creation, preservation, a classification, and reference. Furthermore, extension to high-speed network is considered. Our study has produced the following results :1.Development of a 3D contents work supporting function. We develop a 3D modeler that can support creating new 3D forms and animations by applying an Interactive Evolutionary Computation (IEC) framework. Moreover, this modeler provides an input function that attains free molding by handwriting.2.Development of color image creation supporting function. Color scheme supporting tool is realized by using the new technique that extracts the color information from existing contents and reflects it to users' color images.3.Construction of the digital database for ceramic potteries. We investigate various aspects of reference when classifying and referring potteries. The Arita ceramic potteries included in the Shibata collection is examined about the form and color information extracted from the photographs.4.Extension to high-speed networked environment. We examine 3D modeling method by using a high-speed mass network, Toyo-no-Kuni hyper-network in Oita Prefecture. Area IX is also considered in order to solve the problem in network, the packet loss at the time of high load, communication delay, and so on.
