Visual Computing Lab won two Award EG-Italy Awards for the best thesis in visual computing

Sep 19th, 2018

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.

Metamolds: our latest SIGGRAPH paper!

Sep 6th, 2018

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.

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.

Independence day ??? Not in Italy...

Jul 4th, 2015

Today our colleague Matteo (Dellepiane) got married with Paola. It was a great ceremony in Genova (birth town of both Matteo and Paola), in a very nice small church on the top of the cliffs and a wonderful sea panorama. After the wedding ceremony, we had a excellent and long lunch (following Italian traditions) in the hills on the back of Genova. Matteo and Paola are leaving for a wonderful honeymoon travel in Mongolia, all of us envy them a lot.

With the best wishes of all the Visual Computing Lab!!!

Tales from the crypt.

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.
