Extrusion and revolution mapping
Akram Halli, Abderrahim Saaidi, Khalid Satori, Hamid Tairi
Article No.: 132
DOI: 10.1145/1857907.1857908

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...

Geodesic image and video editing
Antonio Criminisi, Toby Sharp, Carsten Rother, Patrick P'erez
Article No.: 134
DOI: 10.1145/1857907.1857910

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...

1-Sparse reconstruction of sharp point set surfaces
Haim Avron, Andrei Sharf, Chen Greif, Daniel Cohen-Or
Article No.: 135
DOI: 10.1145/1857907.1857911

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
DOI: 10.1145/1857907.1857912

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...
