    • Improved Half Vector Space Light Transport 

      Hanika, Johannes; Kaplanyan, Anton; Dachsbacher, Carsten (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      In this paper, we present improvements to half vector space light transport (HSLT) [KHD14], which make this approach more practical, robust for difficult input geometry, and faster. Our first contribution is the computation ...

    • Manifold Next Event Estimation 

      Hanika, Johannes; Droske, Marc; Fascione, Luca (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present manifold next event estimation (MNEE), a specialised technique for Monte Carlo light transport simulation to render refractive caustics by connecting surfaces to light sources (next event estimation) across ...

    • Portal-Masked Environment Map Sampling 

      Bitterli, Benedikt; Novák, Jan; Jarosz, Wojciech (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present a technique to e ciently importance sample distant, all-frequency illumination in indoor scenes. Standard environment sampling is ine cient in such cases since the distant lighting is typically only visible ...
