Interactive dissemination of the 3D model of a baroque altarpiece: a pipeline from digital survey to game engines

The dissemination of reality-based models allows a more exhaustive knowledge of the object of study and enables a better access through real-time applications running on common devices connected to the web. In addition, difficult-to-appreciate works of art can become object of specifically designed serious educational games through the possibilities allowed by game engines. The definition of a pipeline that leads from a reliable acquisition of shape, color and BRDF features to a motivating and satisfying interactive experience is the focus of this paper. It will be analyzed, in an interdisciplinary perspective, and will undergo a series of steps aimed at preserving the features of the work of art without compromising its realistic and fluid visualization, as well as the characteristics at the base of the stylistic and artistic quality.
