    • A software framework for the development of projection-based augmented reality systems 

      Sunet Pérez, Marc; Comino Trinidad, Marc; Karatzas, Dìmosthenis; Chica Calaf, Antonio; Vázquez Alcocer, Pere Pau (2010)
      Comunicació de congrés
      Accés obert
      Despite the large amount of methods and applications of augmented reality, there is little homogenization on the software platforms that support them. An exception may be the low level control software that is provided by ...

      Pujol Puig, Eduard; Chica Calaf, Antonio (Elsevier, 2023-08)
      Article
      Accés obert
      In this paper, we present an adaptive structure to represent a signed distance field through trilinear or tricubic interpolation of values, and derivatives, that allows for fast querying of the field. We also provide a ...

    • Easy authoring of image-supported short stories for 3D scanned cultural heritage 

      Comino Trinidad, Marc; Chica Calaf, Antonio; Andújar Gran, Carlos Antonio (European Association for Computer Graphics (Eurographics), 2020)
      Text en actes de congrés
      Accés obert
      Visual storytelling is a powerful tool for Cultural Heritage communication. However, traditional authoring tools either produce videos that cannot be fully integrated with 3D scanned models, or require 3D content creation ...
    • Effective visualization of sparse image-to-image correspondences 

      Andújar Gran, Carlos Antonio; Chica Calaf, Antonio; Comino Trinidad, Marc (European Association for Computer Graphics (Eurographics), 2020)
      Text en actes de congrés
      Accés obert
      Finding robust correspondences between images is a crucial step in photogrammetry applications. The traditional approach to visualize sparse matches between two images is to place them side-by-side and draw link segments ...
    • Error-aware construction and rendering of multi-scan panoramas from massive point clouds 

      Comino Trinidad, Marc; Andújar Gran, Carlos Antonio; Chica Calaf, Antonio; Brunet Crosa, Pere (2016-09-30)
      Article
      Accés obert
      Obtaining 3D realistic models of urban scenes from accurate range data is nowadays an important research topic, with applications in a variety of fields ranging from Cultural Heritage and digital 3D archiving to monitoring ...
