Fast Polyhedral Cell Sorting for Interactive Rendering of Unstructured Grids
Direct volume rendering based on projective methods works by projecting, in visibility order, the polyhedral cells of a mesh onto the image plane, and incrementally compositing th...

Novel Depth Cues from Uncalibrated Near-field Lighting
We present the first method to compute depth cues from images taken solely under uncalibrated near point lighting. A stationary scene is illuminated by a point source that is move...

Combinatorial statistics on type-B analogues of noncrossing partitions and restricted permutations
We define type-B analogues of combinatorial statistics previously studied on noncrossing partitions and show that analogous equidistribution and symmetry properties hold in the ca...
