    • An Improved Multiple Importance Sampling Heuristic for Density Estimates in Light Transport Simulations 

      Jendersie, Johannes; Grosch, Thorsten (The Eurographics Association, 2018)
      Vertex connection and merging (VCM) is one of the most robust light transport simulation algorithms developed so far. It combines bidirectional path tracing with photon mapping using multiple importance sampling (MIS). ...

    • Matrix Bidirectional Path Tracing 

      Chaitanya, Chakravarty Reddy Alla; Belcour, Laurent; Hachisuka, Toshiya; Premoze, Simon; Pantaleoni, Jacopo; Nowrouzezahrai, Derek (The Eurographics Association, 2018)
      Sampled paths in Monte Carlo ray tracing can be arbitrarily close to each other due to its stochastic nature. Such clumped samples in the path space tend to contribute little toward an accurate estimate of each pixel. ...

    • Primary Sample Space Path Guiding 

      Guo, Jerry Jinfeng; Bauszat, Pablo; Bikker, Jacco; Eisemann, Elmar (The Eurographics Association, 2018)
      Guiding path tracing in light transport simulation has been one of the practical choices for variance reduction in production rendering. For this purpose, typically structures in the spatial-directional domain are built. ...
