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:
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...
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...
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...
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...
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...

Matteo Bracci and Thomas Alderighi have won both the two the EG-Italy Awards for the best Bachelor and Master thesis in visual computing
Matteo's thesis described the development of HexaLab an innovative WebGL application for real time visualization, exploration and assessment of hexahedral. The system runs directly in a web browser and targets both users and scholars who employ hexahedral meshesfor Finite Element Analysis, and allows to readily inspect and check mesh quality, assessing its usability for simulations.
Thomas's thesis described MetaMolds a novel technique for the fabrication of digital objects through reusable silicone molds. This new method allows for the automatic generation of special 3D printable structures, called Metamolds, that are used as a rigid mold for the silicone mold parts, automatically determining the mold shape given an input digital object.

This August we presented our latest paper about Computational Fabrication at SIGGRAPH 2018, Vancouver. Our paper has also been selected for the official trailer of the technical papers program!
In the paper, titled "Metamolds: Computational Design of Silicone Molds", we presented a novel technique for the fabrication of digital objects through reusable silicone molds. The method allows for the automatic generation of special 3D printable structures, called Metamolds, that are used as a rigid mold for the silicone mold parts, automatically determining the mold shape given an input digital object.
The technique we proposed is automatic and doesn't require any previous knowledge by the user, and is able to reproduce objects with complex shapes.
Please, for more details, or to have a look at the paper, refer to the public page of the project!

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.
