      Biasotti, S.; Marini, S. (The Eurographics Association, 2006)
      The paper describes a method for recognizing similar sub-parts of objects described by 3D polygonal meshes. The innovation of our method is the coupling of structure and geometry in the matching process. First of all, the ...
    • 3D data segmentation using a non-parametric density estimation approach 

      Castellani, U.; Cristani, M.; Murino, V. (The Eurographics Association, 2006)
      In this paper, a new segmentation approach for sets of 3D unorganized points is proposed. The method is based on a clustering procedure that separates the modes of a non-parametric multimodal density, following the mean-shift ...
    • A study on textures and their perceptual visual dimensions as application for flexible and effective scientific visualization 

      Taponecco, F. (The Eurographics Association, 2006)
      The use of textures is fundamental in several areas of Computer Graphics, Computer Vision and Image Processing. In this work, we focus on their main relevant attributes, in order to define and design textures as effective ...
    • Use of Shader Technology for Realistic Presentation of Train Prototypes in Virtual Reality 

      Gironimo, G. Di; Papa, S. (The Eurographics Association, 2006)
      The aim of the paper is to make up a virtual showroom and work-through of a train model in order to allow railway companies showing new trains prototypes, in phase of concept, and present their new design in more exhaustive ...
    • Preparation of Finite Element Models: The Use of an a Posteriori Mechanical Criterion 

      Ferrandes, R.; Marin, P. M.; Léon, J-C.; Giannini, F. (The Eurographics Association, 2006)
      A geometrical model needs to be simplified to perform a FE (Finite Element) analysis. Several tasks of shape processing are required during the FE model preparation phase. An appropriate geometric model and a suitable set ...
