Abstract
In recent years, the rising popularity of 3D models in the field of Cultural Heritage has brought additional geo-spatial formats for its documentation, making necessary to test new approaches in managing, publishing and studying heterogeneous data in an integrated way. Nowadays several computer applications and IT instruments are available for the management of cultural, archaeological and environmental heritages. The large size and complex nature of data makes it difficult for heritage experts to manage them for run more complex spatial analyses. Furthermore, it is also more difficult for citizens to access 3D models aimed at tourism and education. In this paper, we analyze recent low-poly methods aimed at reducing the size and complexity of 3D models applied to the case study of an historical building of Bari (Italy). The main idea is to create simple geometries (through low-poly algorithms) to significantly reduce the number of polygons in the reality-based environment and publish the model on the web. After the comparative evaluation of different low-poly algorithms and the generation of a test model, a PostgreSQL DBMS and a front-end PHP interface were developed to allow users to analyze and query the model.
