The Renaissance palace of Ayerbe in Tauste. Virtual to variable display solid model

Abstract

Digital design tools have been inseparable from every element of the professional architectural graphic process for decades. As they spread, emerging digital tools are changing aspects of design, data collection, edition, fabrication, and architectural visualization. Furthermore, with the example of photography as a widespread mean of capturing and representing heritage, the agents involved in the architectural memory transmission process and their possibilities are changing too. This evolution has gone along with the exponential access to personal computers, digital equipment and manufacturing tools.

The models and images generated by these systems open the doors to new expressive possibilities of great precision and economy. The hardware technology used in the presented case, 3 d printers and high definition projectors, are available to most of agents involved or interested in architectural heritage and preservation of its memory. The purpose of this paper is to study the result of superposing several building's images over its printed model, both with a common origin in the same digital model. The printed model adds the advantages of its presence in real space and the video projection its high degree of variability resulting in a direct augmentation of the visual information provided.

The variability of the digital architectural object and the graphic expression that surges from the combinations of these digital tools are studied to represent the building in an utmost informative way. In the case presented here by the authors, the transcendence of the virtual model from digital to physical space is studied aiming to grade its functionality for exhibition, academic or experimental purposes.
