For the purpose of making the public at large more aware of the management and construction process of some of the major public works carried out in Spain, in this case the 1812 Constitution Bridge over Cadiz Bay, the Fundación ACS and the Real Academia de Bellas Artes de San Fernando, are collaborating in the creation of this website and also in the setting up of a 3D video on display from 18 April 2016 in the academy’s museum at Calle Alcalá,13 in Madrid.
Drone flights carried out at the 1812 Constitution Bridge enabled us to take a host of photographs that were then used for photogrammetric reconstruction of bridge structures.
Working with this data on our equipment, we have been able to build up a 3D reconstruction of the bridge structure. We then used the photogrammetric data to hone the virtual models and add photorealistic textures to the picture.
The purpose of the Autocad drawings is to define the parts to be built and offer accurate technical information on bridge construction. The virtual images are then used in multimedia content; this means they must be comprehensible at a glance.
3D computer graphics offer a wealth of expressive resources for various levels of public expression. They serve not only for illustrating the basic and executive projects that have to be input during the pre-construction phase but also for presenting an executed project to the media.
