Investigation of the Works of Modern Architecture and the Analysis of its Formation Idea through the Method of Computer Graphics Representation

利用实验室的计算机系统，包括1999会计年度新购买的图形工作站，使用三维CG软件，制作建筑作品的CAD数据（建模），表达CG图像（渲染），并对2个会计年度的各种形式的建筑作品进行形式分析。处理过的建筑作品有AEG的透平工厂、其他厂房和住宅综合体，Peter Behrens的设计，Henry van de Velde的德国Werkbund展览的模型剧场，Sommerfeld的住宅，魏玛包豪斯的导演室和Walter Gropius（和Adolf Meyer）的“Totaltheater”项目，Alexander广场改造竞赛项目，Friedrichstrasse车站广场第二届竞赛项目和Mies van der Rohe的Reichsbank项目。分析了1910- 1930年左右现代主义建筑从新艺术到功能主义的形成时期和成熟阶段的建筑形式结构的变化。虽然到目前为止，对这种过渡的解释是通过视觉判断或风格解释来完成的，但我们的分析表明，可以重新解释它，因为CG表达和渲染处理中的建模技术可能在每个阶段都有一个原始的设计系统。澄清了可以将各个阶段的特征解释为建模和渲染方法的不同。即1910年代新古典主义时期用二维画面进行简单的立方构图和纹理映射，新艺术运动末期的曲面元素化，表现主义时期曲面模型上的曲面自由形成，构成主义与国际风格时期在三维正交坐标系上的空间秩序的形成及其空间与环境的表达。

Using the computer system of our laboratory, including a graphic workstation newly bought in 1999 fiscal year with three-dimensional CG software, CAD data of architectural works was made (modeling), the CG image was expressed (rendering), and the formal analysis was tried for architectural works of various forms for 2 fiscal year.The treated architectural works are AEG turbine factory, other factory buildings and housing complex by Peter Behrens, the model theater at German Werkbund exhibition by Henry van de Velde, Sommerfeld house, the director's room of Weimar Bauhaus and "Totaltheater" project by Walter Gropius (and Adolf Meyer), the project for Alexander Platz remodeling competition, the project for the second competition for the square of Friedrichstrasse station and Reichsbank project by Mies van der Rohe. The change in the architectural form structure of the formation period and the mature stage of the modernism architecture in about 1910-about 1930 which arrived from art nouveau (Jugendstil) to the functionalism was analyzed.As though the interpretation of such transition was finished by a visual judgment or style interpretation so far, our analysis has showed that it is possible to reinterpret is as that the technique of modeling in the CG expression and the rendering processing might have a design system original in each stage. It was clarified to be able to interpret the characteristics of each stage as the difference of method on modeling and rendering. That is, simple cubic composition and texture mapping with two-dimensional pictures at Neoclassicism period in 1910's, curved surface elementalization at the end of Art Nouveau period, free formation with curved plane on surface model at Expressionism periods, and formation of spatial order on the three-dimensional orthogonal coordinate system and its spatial and environmental expression at Constructivism and International Style period.
