25 Semantic Annotation of Digital 3D Objects (2009)
Marco Attene, Francesco Robbiano, Michela Mortara, Michela Spagnuolo, Bianca Falcidieno
Abstract—In this demo we show two new techniques for performing semantic annotation of 3D digital objects. The first tool, the ShapeAnnotator, is more general-purpose, and concerns a system to...
Mapping independent triangulation of parametric surfaces (2008)
Marco Attene, Bianca Falcidieno, Michela Spagnuolo
Typical methods for the triangulation of parametric surfaces use a sampling of the parameter space, and the wrong choice of parameterization can spoil a triangulation or even cause the algorithm to...
Part-based Annotation of Virtual 3D Shapes Abstract (2008)
Marco Attene, Francesco Robbiano
In the latest years, distributed virtual worlds populated by static and dynamic 3D shapes have grown significantly, and the need to model and process them effectively has become a critical issue. The...
Geometry and Object Modeling – geometric algorithms; (2008)
Due to the focus of popular graphic accelerators, triangle meshes remain the primary representation for 3D surfaces. They are the simplest form of interpolation between surface samples, which may...
Combinatorial 3-manifolds from sets of tetrahedra (2008)
We propose an algorithm to convert a tetrahedral mesh with singularities to a combinatorial 3-manifold using only local modifications. We outline sufficient conditions on the mesh to guarantee the...

3D scanners, iso-surface extraction procedures, and several recent geometric compression schemes sample surfaces of 3D shapes in a regular fashion, without any attempt to align the samples with the...
Semantic Annotation of 3D Surface Meshes based on Feature Characterization (2008)
Marco Attene, Francesco Robbiano, Michela Spagnuolo, Bianca Falcidieno
Abstract. In this paper we describe the main aspects of a system to perform non-trivial segmentations of 3D surface meshes and to annotate the detected parts through concepts expressed by an...

Figure 1: The original model (on the left, courtesy of Cyberware) containing 134,074 triangles requires 4,100,000 bytes, when stored as a WRL file. A dense partitioning of its surface into deformed...
Advanced remote inspection and download of 3D shapes (2007)
Danovaro, Emanuele, Papaleo, Laura, Sobrero, Davide, Attene, Marco, Saleem, Waqar
Shape inspection options in most of the current online shape repositories provide limited information on the shape of a desired model. In addition, stored models can be downloaded only at the...
Remesh: An interactive environment to edit and repair triangle meshes (2006)
Marco Attene, Bianca Falcidieno
Polygonal meshes obtained from acquisition of real-world objects may easily exhibit topological or geometrical defects, which often prevent subsequent processing and analysis to provide satisfactory...
M.: Hierarchical mesh segmentation based on fitting primitives (2006)
Marco Attene, Bianca Falcidieno, Michela Spagnuolo
In this paper we describe a hierarchical face clustering algorithm for triangle meshes based on fitting primitives belonging to an arbitrary set. The method proposed is completely automatic, and...

SwingWrapper: Retiling Triangle Meshes for Better Compression (2002)
Attene, Marco, Falcidieno, B. (Bianca), Spagnuolo, Michela, Rossignac, Jaroslaw R.
We focus on the lossy compression of manifold triangle meshes. Our SwingWrapper approach partitions the surface of an original mesh M into simply connected regions, called triangloids. From these, we...

Automatic surface reconstruction from point sets in space (2000)
Marco Attene, Michela Spagnuolo
In this paper an algorithm is proposed that takes as input a generic set of unorganized points, sampled on a real object, and returns a closed interpolating surface. Specifically, this method...
