Who are we? Where are we going?

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:

Interactive Graphics

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...

3D Graphics for Cultural Heritage

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

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...

Tales from the crypth.

Apr 21th, 2015

The VCG lab, as a partner of the European project Iperion, made the 3D reconstruction of the rock-cut church of S. Angelo, Mottola (TA), ITALY.The structure develops on two underground floors both divided into three still well-preserved frescoed naves. The lower floor was primarily used as a burial crypt as evidenced by the presence of several graves, lined up on the floor, and a chapel, which served as a cell for the guardian monk. Aims of the campaign were the acquisition of an accurate three-dimensional model for the metrical analysis combined with a good photographic documentation about the conservation state of some frescoes. But don't worry, you'll soon experience the thrill to visit this amazing crypt with the virtual navigation!

The Alexander Mosaic.

Apr 21th, 2015

The VClab lab, as a partner of the European project Iperion, took part in conservation-oriented analysis of 'The Alexander Mosaic' preserved at the National Archaeological Museum of Naples. The artwork, portraying the battle of Issus between Alexander the Great and Darius III, was discovered in 1831 in Pompeii on the floor inside the House of the Faun, measures 582 × 313 cm and consists of about one and a half million tiny polychrome tiles next to 4 mm of side.The Vcg lab created the three-dimensional model of the mosaic using a structured light scanner. The surface in question, glossy, flat and very smooth, has required the acquisition of a large amount of data.

Superb result for VClab at SIGGRAPH 2015, the computer graphics top conference.

Apr 21th, 2015

The preliminary results of the ACM SIGGRAPH 2015 selection process has been recently announced. Three submissions from Visual Computing Lab have been conditionally accepted. This would be an excellent result, since SIGGRAPH is the premier worldwide event in computer graphics and visual technologies, with an extremely tough selective process.Let us wait for the final acceptation to disclose the title and authors of these works. Those submission are on Geometry Processing (Digital Fabrication e Interactive 3D Modeling for Entertainement Industry). Stay tuned...
