Paneling building facades is one of the essential procedures in building construction. Traditionally, it has been an easy task of simply projecting paneling patterns drawn in drawing boards onto 3d building facades. However, as many organic or curved building shapes are designed and constructed in modern architectural practices, the traditional one-to-one projection is becoming obsolete for the building types of the kind. That is primarily because of the geometrical discrepancies between 2d drawing boards and 3d curved building surfaces. In addition, curved compound surfaces are often utilized to accommodate the complicated spatial programs, building codes, and zoning regulations or to achieve harmonious geometrical relationships with neighboring buildings in highly developed urban contexts. The use of the compound surface apparently makes the traditional paneling pattern projection more challenging. Various mapping technics have been introduced to deal with the inabilities of the projection methods for curved facades. The mapping methods translate geometries on a 2d surface into a 3d building façade at the same topological locations rather than relying on Euclidean or Affine projection. However, due to the intrinsic differences of the planar 2d and curved 3d surfaces, the mapping often comes with noticeable distortions of the paneling patterns. Thus, this paper proposes a practical method of drawing paneling patterns directly on a curved compound surface utilizing Geodesic, which is faithful to any curved surface, to minimize unnecessary distortions.

지난 회에서는 형태와 형태이면에 있는 구현의 논리를 모두 다룰 수밖에 없는 파라메트릭 툴의 성격에 대하여 간략하게 이야기 해보았고 이를 반증할수 있는 곡면상의 패널링의 예를 살펴 보았습니다. 삼차원 곡면으로 인해 발생하는 패널들의 시각적 왜곡 및 구축상의 어려움을 해결하고자 왜곡이 발생하는 물리적인 이유를 이해하고 이를 미적분의 개념을 빌어 해결해 보았습니다. 오늘 살펴볼 예도 이와 비슷한 미적분의 개념을 빌리게 되지만 문제의 해결을 위함이 아닌 자연 현상을 시뮬레이션 하고 시뮬레이션의 결과로 얻어진 데이터를 설계에 반영하기 위함이라는데에 차이가 있다고 할 수 있겠습니다. 오늘 살펴볼 내용은 Harvard GSD에서 대학원 설계 수업의 일환으로 제가 진행하였던 파라메트릭 디자인 워크샵의 결과물이며 추후에 이를 실무에 이용하게 됩니다.
