Implementing mesh-based approaches for deformable objects on GPU
Ranzuglia G., Cignoni P., Ganovelli F., Scopigno R.
These latest years witnessed an impressive improvement of graphics hardware both in terms of features and in terms of computational power. This improvement can be easily observed in computer games, where effects which, until few years ago, could only be achieved with expensive CPU computation are now shown interactively. Although the GPU has been designed for implementing graphics effects, it is still it basically a processing unit with its own memory, and, being specialized for algebraic tasks, supplies a number of floating point operations per second which is orders of magnitude greater than the CPU. This suggested to the graphics community that the GPU could also be used for general purpose computation and a number of papers have been published on how to hack the GPU to this target. Following this trend we propose a framework for using GPU for implementing techniques for deformable objects represented as generic meshes. The framework only assumes than the global computation is the union of local computations, which is true for all the explicit methods.Source: Eurographics Italian Chapter 2006, pp. 213–218, Catania, Italy, 22-24/02/2006

Portalada: a virtual reconstruction of the entrance of the Ripoll Monastery
Besora I., Brunet P., Callieri M., Chica A., Corsini M., Dellepiane M., Morales D., Moyes J., Ranzuglia G., Scopigno R.
The dichotomy between detail representation and data management is still a big issue in the context of the acquisition and visualization of 3D objects, especially in the field of Cultural Heritage. New technologies give the possibility to acquire very detailed geometry, but very often it's very hard to process the amount of data produced. In this paper we present a project which aimed at virtually reconstructing the impressive (7x11 m.) portal of the Ripoll Monastery, Spain. The monument was acquired using triangulation laser scanning technology, producing a dataset of more than 2000 range maps for a total of more than 1 billion triangles. All the steps of the entire project are described, from the acquisition planning to the final setup for the dissemination to the public. In particular, we show how timeof-flight laser scanning data can be used to obtain a speed up in the alignment process, and how, after model creation and imperfections repairing, an interactive and immersive setup gives the public the possibility to navigate and visualize the high detail representation of the portal. This paper shows that, after careful planning and with the aid of new algorithms, it's now possible to preserve and visualize the highly detailed information provided by triangulation laser scanning also for very large surfaces.Source: Fourth International Symposium on 3D Data Processing, Visualization and Transmission, pp. 89–96, Atlanta, GA, USA, June 18 - 20, 2008

Multiscale acquisition and presentation of very large artifacts: the case of portalada
Callieri Marco, Chica Antoni, Dellepiane Matteo, Besora Isaac, Corsini Massimiliano, Moyes Jordi, Ranzuglia Guido, Scopigno Roberto, Brunet Pere
The dichotomy between full detail representation and the efficient management of data digitization is still a big issue in the context of the acquisition and visualization of 3D objects, especially in the field of the cultural heritage. Modern scanning devices enable very detailed geometry to be acquired, but it is usually quite hard to apply these technologies to large artifacts. In this article we present a project aimed at virtually reconstructing the impressive (7×11 m.) portal of the Ripoll Monastery, Spain. The monument was acquired using triangulation laser scanning technology, producing a dataset of 2212 range maps for a total of more than 1 billion triangles. All the steps of the entire project are described, from the acquisition planning to the final setup for dissemination to the public. We show how time-of-flight laser scanning data can be used to speed-up the alignment process. In addition we show how, after creating a model and repairing imperfections, an interactive and immersive setup enables the public to navigate and display a fully detailed representation of the portal. This article shows that, after careful planning and with the aid of state-of-the-art algorithms, it is now possible to preserve and visualize highly detailed information, even for very large surfaces.Source: ACM journal on computing and cultural heritage (Print) 3 (2011): 14–20. doi:10.1145/1957825.1957827

Processing a complex architectural sampling with MeshLab: the case of Piazza della Signoria
Callieri M., Cignoni P., Dellepiane Ma., Ranzuglia G., Scopigno R.
The paper presents a recent 3D scanning project performed with long range scanning technology showing how a complex sampled dataset can be processed with the features available in MeshLab, an open source tool. MeshLab is an open source mesh processing system. It is a portable and extensible system aimed to help the processing of the typical not-so-small unstructured models that arise in 3D scanning, providing a set of tools for editing, cleaning, processing, inspecting, rendering and converting meshes. The MeshLab system started in late 2005 as a part of a university course, and considerably evolved since then thanks to the effort of the Visual Computing Lab and of the support of several funded EC projects. MeshLab gained so far an excellent visibility and distribution, with several thousands downloads every month, and a continuous evolution. The aim of this scanning campaign was to sample the fac?ades of the buildings located in Piazza della Signoria (Florence, Italy). This digital 3D model was required, in the framework of a Regional Project, as a basic background model to present a complex set of images using a virtual navigation metaphor (following the PhotoSynth approach). Processing of complex dataset, such as the ones produced by long range scanners, often requires specialized, difficult to use and costly software packages. We show in the paper how it is possible to process this kind of data inside an open source tool, thanks to the many new features recently introduced in MeshLab for the management of large sets of sampled point.Source: 4th ISRPS International Workshop 3D-ARCH'2011 3D Virtual Reconstruction and Visualization of Complex Architectures, pp. 205–212, Trento, 2-5 March 2011

MeshLab as a complete tool for the integration of photos and color with high resolution 3D geometry data
Ranzuglia G., Callieri M., Dellepiane M., Cignoni P., Scopigno R.
Even if a precise, detailed geometry is essential for the study and documentation of a CH artifact, lots of information also comes from the color and appearance data. Since a complete reconstruction of the optical properties of an artifact is still hard (or impossible) to achieve, what is normally done is to rely on color data coming from photographic dataset. In this paper, we will describe the tools that MeshLab offers for the generation and processing of color information on a high-resolution 3D model. We will show the basic operations available and present actual projects were these tools have been successfully used. The availability of such advanced color management tools in an Open Source tool is an important instrument for the archeological and CH community. MeshLab is the most complete open source software for the creation and manipulation of high-resolution 3D models of real-world objects.Source: Archaeology in the Digital Era (e-book), edited by Graeme Earl, Tim Sly, Angeliki Chrysanthi, Patricia Murrieta-Flores, Constantinos Papadopoulos, Iza Romanowska, David Wheatley, pp. 406–416.

3D models for cultural heritage: beyond plain visualization
Scopigno R., Callieri M., Cignoni P., Corsini M., Dellepiane M., Ponchio F., Ranzuglia G.
Digital technologies are transforming the way cultural heritage researchers, archaeologists, and curators work by providing new ways to collaborate, record excavations, and restore artifacts. The first Web extra is a video that highlights the Cenobium project, a pioneering Web system for presenting medieval cloisters and sculptures. The second video presents the results of a study using digital 3D technologies to assess the apparent shape similarity of a bronze statuette and drawings, to evaluate a possible innovative attribution hypothesis. The third video presents a very complex restoration project of a statue severely damaged by a recent earthquake in central Italy. The project made extensive use of ICT technologies. The fourth video presents a hypothesis of the original location of some terracotta statues over the old temple of Luni during the Roman Etruscan period in Italy. The fifth video was produced for a 2010 exposition on the Roman Empire held in Tokyo and shows the potential of new visual technologies for presenting works of art and supporting storytelling.Source: Computer (Long Beach Calif.
