      Parallel architectures, in the form of multi-core or multiple computers, have produced a major impact in the field of information technology. GPU devices, as an extreme example of parallel architectures, have been adapted ...

    • Prototype of an Automatic Registration System for the Remains of Archaeological Sites 

      Ruiz, José Luis López; Alvarado, Lidia Ortega; Higueruela, Francisco Ramón Feito (The Eurographics Association, 2019)
      Data acquisition in archaeological excavations is a time consuming task developed on site that must be completed later with the information stored in the database. In this paper, we introduce the work in progress for the ...

      Fukuoka, Miyu; Ando, Shohei; Koizumi, Naoya (The Eurographics Association, 2022)
      We propose an integrated operation system that combines puppet motion capture and human body movements to easily control various movements of a mid-air CG character. The proposed method addresses the problems in controlling ...

    • Prototyping Care: Two Case Studies 

      Clay, Arthur; Trumpy, Giorgio; Weinmann, Michael; Wetzel, Richard (The Eurographics Association, 2023)
      To enable a richer presentation of cultural heritage and its needs, a shift in how artworks are exhibited is necessary. This paper explores two case studies that highlight the significant role of reproductions in showcasing ...

    • Provably Good 2D Shape Reconstruction from Unorganized Cross-Sections
