    • Patterns of Creativity in Design 

      Bilotta, E.; Pantano, P. (The Eurographics Association, 2007)
      One of the most remarkable features of the human mind is its creativity. During the course of this talk we shall be presenting some examples of the creative use of scientific models such as Chua's attractors and Cellular ...

    • A Practical Vision Based Approach to Unencumbered Direct Spatial Manipulation in Virtual Worlds 

      Bettio, Fabio; Giachetti, Andrea; Gobbetti, Enrico; Marton, Fabio; Pintore, Giovanni (The Eurographics Association, 2007)
      We present a practical approach for developing interactive environments that allows humans to interact with large complex 3D models without them having to manually operate input devices. The system provides support for ...

    • Preserving Information from Real Objects to Digital Shapes 

      Albertoni, Riccardo; Papaleo, Laura; Robbiano, Francesco (The Eurographics Association, 2007)
      Nowadays, the success of the scientific enterprise largely depends on the ability of sharing resources among the scientific community. This problem is particularly relevant in the field of Computer Graphics and Vision. ...

    • Product Design, Reverse Engineering, Rapid Prototyping - a Case Study in Cutlery Production 

      Magrassi, Grazia; Bordegoni, Monica (The Eurographics Association, 2007)
      Reverse Engineering and Rapid Prototyping are consolidated practices in the industrial product design process. In any case, best practices should be set up according to the type of product and of objectives. This paper ...

    • Ramses: a Visual Steganographic System 

      Battiato, S.; Blasi, G. Di; Gallo, G.; Patti, S. (The Eurographics Association, 2007)
      Steganography is the art of "secret communication". Its goal is to transmit a message (information) hidden inside another visible message. The typical visible message used in many steganographic systems is a digital image ...
