    • A Frame-dependent oracle for linear hierarchical radiosity: a step towards frame-to-frame 

      Martín Campos, Ignacio Clemente; Tost Pardell, Daniela; Pueyo Sánchez, Xavier (1996-01)
      Research report
      Open Access
      A frame-based oracle for Hierarchical Radiosity (HR) is proposed which takes into account the Gouraud shading interpolated intensity values mapped from the radiosities. The algorithm is based on a linear approximation ...
    • A Global algorithm for linear radiosity 

      Sbert Cassasayas, Mateu; Pueyo Sánchez, Xavier (1993-11)
      Research report
      Open Access
      A linear algorithm for radiosity is presented, linear both in time and storage. The new algorithm is based on previous work by the authors and on the well known algorithms for progressive radiosity and Monte Carlo particle ...
    • A parametric-space-based scan-line algorithm for rendering of bicubic surfaces 

      Pueyo Sánchez, Xavier; Brunet Crosa, Pere (1987)
      Article
      Open Access
      A novel scan-line algorithm for displaying bicubic surfaces is presented. Patches are decomposed on regions of constant sign of the z component of the normal before the scan process. Most of the computations are done in ...
    • Multilevel use of coherence for complex radiosity environments 

      Vilaplana Pastó, Josep; Pueyo Sánchez, Xavier (1993-02)
      Research report
      Open Access
      The performance of radiosity algorithm has been improved in the last years by means of using coherence when evaluating the visibility function for form factor computation. We present here a characterization of the uses of ...

    • Temporal coherence in progressive radiosity 

      Tost Pardell, Daniela; Pueyo Sánchez, Xavier (1993-02)
      Research report
      Open Access
      In this paper we firstly present a study of the use of temporal coherence in radiosity algorithms. We underline the fact that this may be used even in static environments given that the behavior of a radiosity algorithm, ...
    • The Use of visibility coherence for radiosity computation 

      Pueyo Sánchez, Xavier (1993-01)
      Research report
      Open Access
      Coherence has been widely used to improve the performance of visibility computation in traditional hidden line/surface algorithms. The appearance of radiosity algorithms has increased the importance of computing efficiently ...
