    • Two-Level Grids for Ray Tracing on GPUs 

      Kalojanov, Javor; Billeter, Markus; Slusallek, Philipp (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      We investigate the use of two-level nested grids as acceleration structure for ray tracing of dynamic scenes. We propose a massively parallel, sort-based construction algorithm and show that the two-level grid is one of ...

    • Walking On Broken Mesh: Defect-Tolerant Geodesic Distances and Parameterizations 

      Campen, Marcel; Kobbelt, Leif (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Efficient methods to compute intrinsic distances and geodesic paths have been presented for various types of surface representations, most importantly polygon meshes. These meshes are usually assumed to be well-structured ...

    • Wavelet Rasterization 

      Manson, Josiah; Schaefer, Scott (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      We present a method for analytically calculating an anti-aliased rasterization of arbitrary polygons or fonts bounded by Bezier curves in 2D as well as oriented triangle meshes in 3D. Our algorithm rasterizes multiple ...
