Sagrada Familia Nativity facade - 3D modeling from point clouds

Works carried out by Modelical for the Junta Constructora del Templo de Sagrada Familia.

You have probably heard of the basilica of the Sagrada Familia in Barcelona, a project by Antoni Gaudí. Surely you are aware that it is a building begun in 1882 and that it is still being designed and built, with the latest technologies available. What you may not know is that until 2018 the Nativity façade, which is a UNESCO World Heritage Site, had no reliable documentation describing it, either in two or three dimensions.

On the occasion of the restoration and cleaning works, a topography team was commissioned to survey the entire façade with point clouds and photogrammetry. From this work, Modelical's commission was to 3D model the whole set, both with NURBS surfaces and meshes, and extract 2D documentation of plan layouts and sections describing the facade.
