    • Time Line Cell Tracking for the Approximation of Lagrangian Coherent Structures with Subgrid Accuracy 

      Kuhn, A.; Engelke, W.; Rössl, C.; Hadwiger, M.; Theisel, H. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Lagrangian coherent structures (LCSs) have become a widespread and powerful method to describe dynamic motion patterns in time-dependent flow fields. The standard way to extract LCS is to compute height ridges in the ...

    • Visibility Silhouettes for Semi‐Analytic Spherical Integration 

      Nowrouzezahrai, Derek; Baran, Ilya; Mitchell, Kenny; Jarosz, Wojciech (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      At each shade point, the spherical visibility function encodes occlusion from surrounding geometry, in all directions. Computing this function is difficult and point‐sampling approaches, such as ray‐tracing or hardware ...

    • Visualization of the Centre of Projection Geometrical Locus in a Single Image 

      Stojaković, V.; Popov, S.; Tepavčević, B. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Single view reconstruction (SVR) is an important approach for 3D shape recovery since many non‐existing buildings and scenes are captured in a single image. Historical photographs are often the most precise source for ...
