This thread is focused on the use of cutting-edge Computer Graphics for the support of Cultural Heritage. This includes not only the presentation of artifacts to the public, but also the development, experimentation and dissemination of new algorithms and tools to help the experts (art historians, restorers, archeologists) in their everyday work.
The “3D Graphics for Cultural Heritage” thread works in close collaboration with the other threads of the Laboratory, sharing the results of the research in order to adapt and improve them for this specific context. For any clarification or information, please contact Matteo Dellepiane firstname.lastname@example.org
The Laboratory has a strong tradition in the context of 3D Scanning. This was exploited both in creating tools for data processing and visualization of data, and in practical experience in the context of important acquisition campaigns. Some recent major 3D scanning experiences are:
The acquisition of the Ruthwell Cross, in collaboration with the Visionary Cross project.
The scanning of Insula V in Pompei, in collaboration with University of Lund
3D Scanning and acquisition of color appearance in the context of the analysis of the fractures in the lower part of Michelangelo’s David.
One of the main fields of research in the last few years has been in the necessity to add highly detailed color information to 3D geometry. In particular, the most recent works address the issues of:
Automatic registration of images onto 3D models.
Preserving fine details in color projection.
Registration of video sequences onto 3D models.
SVBRDF approximation from video sequences.
RTI images are a valid alternative to 3D acquisition in some CH scenarios. The Lab has experience in data acquisition and visualization of RTI images.
Geometry processing techniques can be applied to a very interesting field of application: the analysis of chisel marks and the small details of artworks
Another research topic of the Lab is Computer Graphics used for the study, digital reconstruction and visualization of the ancient colour of artworks, especially focussing on the issue of polychrome marble surfaces as, for example, Roman sarcophagi (I-IV century AD).
One of the strong points of the Lab is the application of cutting-edge technologies in the professional work of Restorers and Art Historians. Some recent results include:
The integration of 2D and 3D data for documentation and analysis: Photocloud
Support to restoration and reassembly of fractured objects.
Monitoring of excavation sitesusing 3D-from-images.
The Lab promotes the use of Freeware and Open Source tools (in particular MeshLab) through the participation to International Schools and Workshops, but also through activity:
In the web: MeshLab Video Tutorials.
Through university courses.
The Visual Computing Lab promotes the activities on ICT & CH by participating to the organization of scientific events and the management of scientific journals:
