Extrusion, bevel, chamfer, and lathe tools are widely used in a large variety of computer graphics applications such as architectural designs and industrial prototyping of manufactured goods. However, such modeling is usually based on polygonal...
This article presents a new, unified technique to perform general edge-sensitive editing operations on n-dimensional images and videos efficiently.
The first contribution of the article is the introduction of a Generalized Geodesic Distance...
ℓ1-Sparse reconstruction of sharp point set surfaces
Haim Avron, Andrei Sharf, Chen Greif, Daniel Cohen-Or
Article No.: 135
We introduce an ℓ1-sparse method for the reconstruction of a piecewise smooth point set surface. The technique is motivated by recent advancements in sparse signal reconstruction. The assumption underlying our work is that common...
A PML-based nonreflective boundary for free surface fluid animation
Andreas Söderström, Matts Karlsson, Ken Museth
Article No.: 136
This article presents a novel nonreflective boundary condition for the free surface incompressible Euler and Navier-Stokes equations. Boundaries of this type are very useful when, for example, simulating water flow around a ship moving over a wide...
