Description du sujet du stage/Internship description (une dizaine de lignes/about ten lines) :
| One of the most popular methods in flow visualization consists
of placing a set of streamlines which are always tangential to the
flow in order to emphasize the global field coherency. Beside, high quality placement of streamlines has recently proven
relevant for other applications such as non-photorealistic rendering
or curve-based surface remeshing. The goal of this internship is to elaborate upon an algorithm for high quality placement of streamlines on triangulated surfaces. Although a high quality streamline placement has no formal definition, it is admittedly related to the uniformity of streamlines as well as to the spacing with respect to the desired density. In particular, we will investigate the possibility to avoid the need for any parameterization stage, and will resort to a 3D Delaunay triangulation restricted to the input surface instead.Targeted applications are anisotropic remeshing of surfaces and visualization of flow fields on surfaces. |
