  • Marques, Ricardo; Bouville, Christian; Ribardière, Mickaël; Santos, Luís Paulo; Bouatouch, Kadi (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    The Monte Carlo method has proved to be very powerful to cope with global illumination problems but it remains costly in terms of sampling operations. In various applications, previous work has shown that Bayesian Monte ...
  • Dutra, T. B.; Marques, Ricardo; Cavalcante‐Neto, J.B.; Vidal, C. A.; Pettré, J. (Wiley, 2017)
    Most recent crowd simulation algorithms equip agents with a synthetic vision component for steering. They offer promising perspectives through a more realistic simulation of the way humans navigate according to their ...
  • Marques, Ricardo; Bouville, Christian; Bouatouch, Kadi (Wiley, 2018)
    This paper proposes optimal quadrature rules over the hemisphere for the shading integral. We leverage recent work regarding the theory of quadrature rules over the sphere in order to derive a new theoretical framework ...
  • Bahrehmand, Arash; Batard, Thomas; Marques, Ricardo; Evans, Alun Thomas; Blat, Josep (Elsevier, 2017)
    Computational design is one of the most common tasks of immersive computer graphics projects, such as games, virtual reality and special effects. Layout planning is a challenging phase of architectural design, which ...
  • Marques, Ricardo; Bouville, Christian; Bouatouch, Kadi (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    We propose a theoretical framework, based on the theory of Sobolev spaces, that allows for a comprehensive analysis of quadrature rules for integration over the sphere. We apply this framework to the case of shading ...
  • Marques, Ricardo; Bouville, Christian; Ribardière, Mickaël; Santos, Luís Paulo (Wiley, 2013)
    Quasi-Monte Carlo (QMC) methods exhibit a faster convergence rate than that of classic Monte Carlo methods. This feature has made QMC prevalent in image synthesis, where it is frequently used for approximating the value of ...
