    • 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 ...

    • Revisiting decomposition analysis of geometric constraint graphs 

      Joan Arinyo, Robert; Soto Riera, Antoni; Vila Marta, Sebastià; Vilaplana Pastó, Josep (2002-02)
      Research report
      Open Access
      Geometric problems defined by constraints can be represented by geometric constraint graphs whose nodes are geometric elements and whose arcs represent geometric constraints. Reduction and decomposition are techniques ...
    • Transforming an under-constrained geometric constraint problem into a well-constrained one 

      Joan Arinyo, Robert; Soto Riera, Antoni; Vila Marta, Sebastià; Vilaplana Pastó, Josep (2002-12)
      Research report
      Open Access
      We present an approach for handling geometric constraint problems with under-constrained configurations. The approach works by completing the given set of constraints with constraints that can be defined either ...
    • Volume cutting to simulate transurethral resection of the prostate 

      Joan Arinyo, Robert; Vilaplana Pastó, Josep (2006-02)
      Research report
      Open Access
      Simulating cutting processes of human tissue is an important feature in virtual reality systems for medical training and rehearsal. In this paper we present a method to simulate the cutting operation in voxel-based virtual ...
