Assessing 3D geovisualization for the communication of public art

This paper presents the assessment of a 3D geovisualization framework and system for the documentation and communication of contemporary public art. The paper reviews the specific requirements of the contemporary public art and discusses the critical issues connected to the visualization of such artworks. The framework implements a visualization pipeline that relies on both a semantic representation of the artworks and a mixture of graphic elements acquired from reality or designed for the application. The web-based visualization system realizes a geolocalized 3D layout that selects the relevant traits that characterize the contemporary public artworks. The system is implemented in a prototype applied to the visualization of contemporary public artworks of the municipality of Turin (Italy). The assessment is achieved through the evaluation of a number of typical tasks that general audiences engage with contemporary public art, the system has revealed to be more adequate to its design goals.
