TAHARA Shinnosuke was known as the designer of the Yamagata Prefectural Government Building and the Assembly Hall, which are nationally designated important cultural properties. “Restoration of Yamagata Prefectural Government Building and Assembly Hall Vol. 1” (hereinafter referred to as “Restoration”) shows TAHARA's history and career, and lists the names of his works involved. By the way, TAHARA became the apprentice of Condor from an early stage and worked at the Condor office, so many of the works that TAHARA engaged in can be considered as Condor’s works.

 However, in the past, 16 cases considered to be Condor’s work and shown only in TAHARA's career were considered “unclear whether planned or implemented”. That was because only the construction name was quoted from TAHARA's “CV” in “Restoration”.

 Therefore, this article considered TAHARA's original “CV”, and examined 16 constructions. As a result, the French Embassy was not described in the original “CV”, and the Yokohama Yamashita-cho 5 ban Club Hotel was judged to be the same building as the Yokohama Yamashita-cho United Club. The following is an overview of the remaining 14 works. Of the 14 cases, 7 of Tsukiji Metropole Hotel, Yokohama Yamashita-cho 85 ban Maples Club, Yokohama Yamashita-cho 101 ban seicha kaisha souko oyobi seichaba, Yokohama Yamashita-cho kou 90 bankan Uotaa shi shokai, Yokohama Yamashita-cho 30 bankan, Akasaka-ku Omote-cho Shippa shi jutaku, Yokohama Yamashita-cho 111 ban US Navy Coal Storage are Conder’s works that TAHARA was involved in the construction. The Mitｓubishi sha Osaka shiten was the work of SONE Tatsuzo, although TAHARA was involved in the construction, and Waseda Okuma hakushaku tei onshitsu was the work of TAHARA himself. And four cases of Aoyama-gakuin kosha oyobi kishukusha, Yokohama Yamashita-cho A 3 ban Robinson shokai oyobi soko, Yokohama Yamashita-cho 8 ban Standard shokai, Kojimachi-ku Eiraku-cho Takada shokai honten have not been implemented, and Yokohama kyoryuchi 30 bankan dai 1 gou oyobi dai 2 gou soko warehouse is unknown.

This study analyzed the expression techniques used in animation and found the possibility of developing them into architectural introduction CG. The analysis revealed the following three findings.

1. Typified six types of expressive techniques, “First person view type”, “Second person view type”, “Mirror image type”, “Time lapse type”, “Bokeh practical used type” and “Free floating type.”

2. “Bokeh practical used type” is used very frequently, indicating that it is a very common type of expression techniques for 3DCG animation.

3. Three expression techniques that cannot be typified were considered and proposed for use in the architectural field.

This study aims to clarify the morphological representation of the sloping roof of contemporary architectures that were published in Japanese architectural magazine “A+U” that publishes articles on world architecture. The rooftop view and section figures were analyzed based on convexoconcave, straight or curved, breakpoints, and symmetry. Subsequently, the section figures were analyzed based on their deformation, the grounding angle, finishing material of their walls or roofs and the presence or absence of eaves. Consequently, 33 types of slant roof designs and 6 combination patterns in contemporary architectures were defined by the relationship of the roof surface figures.
