      Khlebnikov, Rostislav; Voglreiter, Philip; Steinberger, Markus; Kainz, Bernhard; Schmalstieg, Dieter (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We propose a technique to build the irradiance cache for isotropic scattering simultaneously with Monte Carlo progressive direct volume rendering on a single GPU, which allows us to achieve up to four times increased ...
    • Stability of Dissipation Elements: A Case Study in Combustion

      Recently, dissipation elements have been gaining popularity as a mechanism for measurement of fundamental properties of turbulent flow, such as turbulence length scales and zonal partitioning. Dissipation elements segment ...
    • Extended Branch Decomposition Graphs: Structural Comparison of Scalar Data 

      Saikia, Himangshu; Seidel, Hans-Peter; Weinkauf, Tino (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We present a method to find repeating topological structures in scalar data sets. More precisely, we compare all subtrees of two merge trees against each other - in an efficient manner exploiting redundancy. This provides ...
    • Mandatory Critical Points of 2D Uncertain Scalar Fields 

      Günther, David; Salmon, Joseph; Tierny, Julien (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      This paper introduces a novel, non-local characterization of critical points and their global relation in 2D uncertain scalar fields. The characterization is based on the analysis of the support of the probability density ...
