4 scenes are rendered with 7 different hemispherical estimators:

  • Mutliple importance sampling (MIS)
  • Adaptive light sample distribution with sample-from-light(ALSD-L).
  • Adaptive light sample distribution with multiple importance sampling(ALSD-MIS).
  • multidimensional hemispherical adaptive sampling with sample-from-light(MDHI-L).
  • multidimensional hemispherical adaptive sampling with multiple importance sampling(MDHI-MIS).
  • Population Monte Carlo Hemispherical Integral Sampler (PMC-HI)
  • Population Monte Carlo Hemispherical Integral Sampler with the population Monte Carlo image plane sampler (PMC-IP-HI)
