Study on a Collaborative 3D Virtual Modeling Environment for Super-Design Technologies

我们研究了超设计技术，可以很容易地将设计师的未成形的图像外化为具体的形状，并从抽象的表达创建计算机图形（CG）模型。基于手势和遗传算法（GA）的新的3D建模方法被发明用于这一目的。此外，我们还开发了一些针对传统工艺美术设计、城市规划和工业设计的应用系统，以评估和验证本发明的方法。本研究取得了以下成果：1.实现了基于手势的三维造型系统，使用户能够直观地创建和变形各种CG模型。用户可以通过直观的手势来描述物体的形状、大小等难以表达的特征.基于遗传算法的三维设计系统，自动设置几何参数和创建新的形状。系统只要求用户对系统生成的每个形状进行评级。它减轻了用户设置适当参数值的负担，并允许他们专注于新几何的概念化和想象。3.以城市规划、土木工程管理、烟花动画制作、陶瓷数据分类与检索为应用对象，对上述两个系统进行了评价，结果发表在IEEE/ACM会议论文和IPSJ/IEICE期刊论文上。我们还申请了其中一部分的专利。

We have studied on the super-design technologies to easily externalize designer's unshaped images to concrete shapes and create computer graphics (CG) models from abstract expressions. New 3D modeling methods based on hand gestures and genetic algorithm (GA) are invented for this purpose. Additionally, we developed some application systems targeted at traditional arts and crafts design, urban planning, and industrial design for evaluation and validation of the invented methods. This study has produced the following results :1. The hand-gesture-based 3D modeling system enabling users to intuitively create and deform various CG models is implemented. The users can easily illustrate object's inexpressible characteristics such as the shape and the size by using intuitive hand gestures.2. The GA-based 3D design system to automate the setting of geometric parameters and the creation of new shapes is developed. The system only requires the users to rate each shape generated by the system. It relieves the users' burden to set up the appropriate parameter values and allows them to concentrate on conceptualization and imagination of the new geometries.3. The application systems aimed at urban planning, civil engineering work management, production of fireworks animation, and ceramics data classification and retrieval are implemented to evaluate the above two systems.These results are published in IEEE/ACM conference papers and IPSJ/IEICE journal papers. We also apply for a patent about a part of them.
