The history of the Visual Computing Lab of CNR-ISTI began more than 25 years ago, with the friendship and collaboration of Claudio Montani (formerly CNR-IEI, now CNR-ISTI Director) and Roberto Scopigno (formerly CNR-CNUCE, now head of the VClab).
We have initially focused on scientific visualization, then moved to geometry processing, multiresolution representation / visualization, deformable models, 3D digitization, texturing and mesh parameterization.
Currently, our main application domain is Cultural Heritage (that is a rather natural choice since we live in Tuscany), including virtual museums, restoration, documentation and rapid reproduction.
Only a minority of the lab members have permanent positions, most of members' salaries are paid by several research projects (EC, Regional and National funds).
Research activity has been recently organized under three main threads:
This branch focuses on interactive algorithms and applications for Computer Graphics, mainly focusing on real-time rendering constraints, with the term rendering intended in a broad sense (photorealistic, massive data management, ad-hoc solutions for specific presentation purposes). Solutions are designed for both desktop and mobile devices; the design of multiresolution data management solutions is a basic resource for many projects in this strand. more...
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. more...
Geometry Processing trend includes methodologies for shape analysis and characterization, mesh parametrization and its applications.
First, we aim to apply such techniques for re-meshing, compression and visualization. This includes quadrilateral mesh generation (useful in the entertainment industry, architectural modeling more...
The Visual Computing Laboratory is proud to present the release of a novel C++11 imaging library, Piccante. Piccante is open source and distributed under the LPGL v3 license. Piccante can provide data structures and functionalities for different domains such as HDR imaging, image processing, and computer vision
Roberto Scopigno is the recipient of the Eurographics 'Distinguished Career Award' 2014, an award given every other year to a professional in computer graphics who has made outstanding technical contributions to the field and has shaped computer graphics in Europe.
Roberto Scopigno’s work has had a profound impact on the field of visual computing, and several contributions truly stand out. Of particular importance has been his work on surface simplification, LOD and multiresolution representations for surfaces and volumes. His papers on these topics have been cited widely and stimulated considerable follow-up work. The BDAM algorithm and its 3D extension, Tetra-Puzzles, grew over ingenious novel data structures for hierarchical seamless space subdivision and have inspired new multiresolution applications for the inspection of terrain models and gigantic meshes. He has been engaged in several research projects (funded by EU and national agencies). He is a recognized and reputed world-wide leader in the development of novel algorithms and techniques for Cultural Heritage and for the acquisition, preservation and visualization of digital copies of physical artifacts inherited from the past.
Roberto Scopigno is a recognized scientific leader. He has created a very successful research group at CNR Pisa, and several of his former students have themselves become well-known productive researchers. He has demonstrated a strong leadership in Computer Graphics research in Europe, and he has been a major actor in shaping Computer Graphics in Italy. Roberto has significantly advanced the field through his work and energy, and by setting a personal example.

The results of a cooperation linking the Visual Computing Lab (ISTI-CNR) and two CH partners, the Foundation Palazzo Blu and the Superintendency in Pisa have been presented with a seminar organized at the Museum Palazzo Blu in Pisa on February 28th, 2014.
ISTI-CNR has digitized those coins using Rflection Transformation Imaging (RTI) technology; the set from the Museum Palazzo Blu was digitized with a proprietary dome for RTI acquisition developed by ISTI-CNR. Then, two multimedia kiosks have been designed and installed in the museums.
The one implemented for Museum Palazzo Blu is now also accessibe via web at url: http://vcg.isti.cnr.it/PalazzoBlu/
As far as we know, this is the first example of RTI digitized material made accessible on the web and enriched by an interactive multimedia system able to integrate the RTI data with standard descriptive information.
