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 at VC Lab spreads several themes:

3D/2D Digitization

This is a consolidated topic of interest for the lab, with many results produced concerning both 3D digitization (scanning systems, algorithms for raw data processing, etc) and 2D methods (here our activity mostly focused on advanced 2D media, such as Reflection Transformation Images and panoramic images). more...

Geometry Processing

Our activity on Geometry Processing 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...

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 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...

3D Fabrication

The main aim of industrial prototyping is to create a tangible representation of an arbitrary digital geometry. In this thread we mainly focus on solving the limitations of current 3D printing technologies. Moreover, we are also interested in leveraging the potential of computational fabrication techniques for the creation of advanced functional artifacts. more...


Hexalab: visualizing complex hexahedral meshes on the web

Jul 9th, 2018

The Visual Compuing Lab has released another tool to the community: HexaLab, a WebGL application for real time visualization, exploration and assessment of hexahedral meshes that runs directly in a web browser (just go to 'HexLab').

This advanced visualization tool targets both users and scholars who employ hexahedral meshes for Finite Element Analysis, and allows to readily inspect and check mesh quality, assessing its usability for simulations.

HexaLab can be used to perform a detailed analysis of the mesh structure, isolating weak points and to generate high quality images using advanced global illumination effects and sophisticated shaping of the elements. To allow effective interactive analysis of the meshing, we support a wide variety of visualization and volume inspection tools like slicing, peeling, quality filtering and minecraft style picking of individual elements.

Finally to promote reproducible research and simple access to the state of the art in this field, HexaLab also offers integrated access to a repository containing all the publicly available meshes produced with the most recent papers for hex mesh generation.

Best paper award at ACM Web3D Conf.

Jul 5th, 2018

We are proud to announce that our paper, 'A Compact Representation of Relightable Images for theWeb', has been conferred with the Best Paper award at the the 23rd Int. ACM Conference on 3D Web Technology!

Congratulation to our collegues Federico Ponchio, Massimiliano Corsini and Roberto Scopigno.

Tensegrity sculpture inaugurated

Sept 29th, 2017

During the last Researcher Night we have officially presented to the public a large Tensegrity structure. It have been built as a proof of the soundness of our approach we introduced in our last Siggraph Asia paper. This Tensegrity sculptural structure was so appealing that the director of the research area decided to permanently place it in the main garden.
