REASSEMBLY OF ROCK SEGMENTS, THE CASE OF AREOPAGUS HILL

There are no specifications and/or standards for the restoration of collapsed masses of rocks, as in most cases the rocks bear no historical/archaeological value and their restoration would require significant budget and resources. But plenty of colossal statues, ancient temples, tombs and whole cities are carved on the surface or even expand in the interior of solid natural rocks. These so-called rock-cut monuments are located all around the globe and, in most cases, are made on a grand scale. Earthquakes, rock’s faults, erosion and karst can lead to massive rock collapses.The purpose of this paper is to establish an integrated methodology for the relocation of detached rock segments to their original positions. Specifically, the proposed methodology is based on the case of the Areopagus Hill and involves the generation of 3d models of the rock segments, their virtual reassembly and their utilization for the reconstruction of a part of the peak of the hill

INVESTIGATING 3D RECONSTRUCTION METHODS FOR SMALL ARTIFACTS

Small artifacts have always been a real challenge when it comes to 3D modelling. They usually present severe difficulties for their 3D reconstruction. Lately, the demand for the production of 3D models of small artifacts, especially in the cultural heritage domain, has dramatically increased. As with many cases, there are no specifications and standards for this task. This paper investigates the efficiency of several mainly low cost methods for 3D model production of such small artifacts. Moreover, the material, the color and the surface complexity of these objects id also investigated. Both image based and laser scanning methods have been considered as alternative data acquisition methods. The evaluation has been confined to the 3D meshes, as texture depends on the imaging properties, which are not investigated in this project. The resulting meshes have been compared to each other for their completeness, and accuracy. It is hoped that the outcomes of this investigation will be useful to researchers who are planning to embark into mass production of 3D models of small artifacts

An Ongoing Experimentation for VR, AR and MAR of a Design Museum

This paper traces the experimental path for the virtualization and enrichment with augmented and mixed reality of some modern design objects of the Design Museum of Milan Triennale. The workflow deals with an ongoing experiment with some trainees of Politecnico di Milano and considers to explore strengths and weaknesses of low cost technologies for digital survey in the contemporary design domain, the uses of these technologies for the realization of virtual museums and settings, the relationship that can emerge between storytelling and the creation of virtual museums containing virtual models and the interactions that the latter can have with the user
