State of the art on stylized fabrication
Bickel B., Cignoni P., Malomo L., Pietroni N.
Digital fabrication devices are powerful tools for creating tangible reproductions of 3D digital models. Most available printing technologies aim at producing an accurate copy of a tridimensional shape. However, fabrication technologies can also be used to create a stylistic representation of a digital shape. We refer to this class of methods as 'stylized fabrication methods'. These methods abstract geometric and physical features of a given shape to create an unconventional representation, to produce an optical illusion or to devise a particular interaction with the fabricated model. In this state-of-the-art report, we classify and overview this broad and emerging class of approaches and also propose possible directions for future research.Source: Computer graphics forum (Print) 37 (2018): 325–342. doi:10.1111/cgf.13327

Metamolds: Computational design of silicone molds
Alderighi T., Malomo L., Giorgi D., Pietroni N., Bickel B., Cignoni P.
We propose a new method for fabricating digital objects through reusable silicone molds. Molds are generated by casting liquid silicone into custom 3D printed containers called metamolds. Metamolds automatically define the cuts that are needed to extract the cast object from the silicone mold. The shape of metamolds is designed through a novel segmentation technique, which takes into account both geometric and topological constraints involved in the process of mold casting. Our technique is simple, does not require to change the shape or topology of the input objects, and only requires off-the-shelf materials and technologies. We successfully tested our method on a set of challenging examples with complex shapes and rich geometric detail.Source: ISTI Technical reports, 2018

FlexMaps: computational design of flat flexible shells for shaping 3D objects
Malomo L., Pérez J., Iarussi E., Pietroni N., Miguel E., Cignoni P., Bickel B.
We propose FlexMaps, a novel framework for fabricating smooth shapes out of flat, flexible panels with tailored mechanical properties. We start by mapping the 3D surface onto a 2D domain as in traditional UV mapping to design a set of deformable flat panels called FlexMaps. For these panels, we design and obtain specific mechanical properties such that, once they are assembled, the static equilibrium configuration matches the desired 3D shape. FlexMaps can be fabricated from an almost rigid material, such as wood or plastic, and are made flexible in a controlled way by using computationally designed spiraling microstructures.Source: ACM transactions on graphics 37 (2018). doi:10.1145/3272127.3275076

Reconstructing power lines from images
Ganovelli F., Malomo L., Scopigno R.
We present a method for reconstructing overhead power lines from images. The solution to this problem has a deep impact over the strategies adopted to monitor the many thousand of kilometers of power lines where nowadays the only effective solution requires a high-end laser scanner. The difficulty with image based algorithms is that images of wires of the power lines typically do not have point features to match among different images. We use a Structure from Motion algorithm to retrieve the approximate camera poses and then formulate a minimization problem aimed to refine the camera poses so that the image of the wires project consistently on a 3D hypothesis.Source: IVCNZ 2018 - International Conference on Image and Vision Computing New Zealand, Auckland, New Zealand, 19-21 November 2018

The EMOTIVE Project - Emotive virtual cultural experiences through personalized storytelling
Katifori A., Roussou M., Perry S., Cignoni P., Malomo L., Palma G., Dretakis G., Vizcay S.
This work presents an overview of the EU-funded project EMOTIVE (Emotive virtual cultural experiences through personalized storytelling). EMOTIVE works from the premise that cultural sites are, in fact, highly emo- tional places, seedbeds not just of knowledge, but of emotional resonance and human connection. From 2016-2019, the EMOTIVE consortium will research, design, develop and evaluate methods and tools that can support the cultural and creative industries in creating narratives and experiences which draw on the power of 'emotive storytelling', both on site and virtually. This work focuses on the project objectives and results so far and presents identified challenges.Source: CI 2018 - Workshop on Cultural Informatics, co-located with the International Conference on Digital Heritage 2018 (EuroMed 2018), pp. 11–20, Nicosia, Cyprus, November 3, 2018
