A study of Gaudí’s apartment block on the Passeig de Gràcia: the undulating stone front, the wrought-iron balconies, the courtyard and the roof terrace with its sculpted chimneys. Free-form geometry like this is a hard test for a model built from code.

高第在格拉西亞大道上的公寓：起伏的石砌立面、鍛鐵陽台、中庭，還有屋頂露台上的雕塑煙囪。這種自由曲面對用程式建模是很硬的考驗。
