The recent developments in the fields of photogrammetry and laser scanning, have made possible mass acquisitions of heritage artifacts with a particularly high level of geometric accuracy. A processing of the digital model will be necessary to isolate some characteristics in order to carry on an analysis of the architectural object. In this poster, the potentialities of the curvature maps, extracted from digital acquisitions, are defined to conduct the study on the morphology of architectural elements. The current work focuses on the technical and theoretical issues that will ultimately result in an average surface signature. This will allow to identify the degree of remoteness of each attribute.

In order to decide which preservation strategies one should follow for Cultural Heritage objects made of stone, it is necessary to estimate the impact of different alternative strategies. A useful aid in such a process is the simulation of the stone degradation process. The first step in such a process is to create realistic digital representations of stones. In this work we present early efforts to create 3D voxelized representations of stones from given 2D example-textures of the desired stone-material. The process aims at the creation of 3D stone materials, consistent with 2D samples. The presented work is one part of the PRESIOUS EU project.
