====== General ======

[[http://viennamesh.sourceforge.net|ViennaMesh]] provides interfaces to a collection of different external libraries and wraps their algorithms for meshing applications. But currently there is no algorithm to generate a mesh based on (3d) image information. [[http://www.cgal.org|CGAL]] provides such an algorithm which should be integrated in ViennaMesh.

Multiple segments within a mesh are important for scientifc computing, especially for simulation.[[http://viennamesh.sourceforge.net|ViennaMesh]] wraps [[http://doc.cgal.org/latest/Mesh_3/index.html#title14|CGALs]] mesh generation algorithm using polyhedral domains but without support for segmentations. An orcale for multi-segment polyhedron domains should be implemented to add support for multi-segment mesh generation using CGALs meshing framework.

====== Prospective Student ======
This project is currently unassigned. 

====== Requirements ======

The student should be familiar with C++ and template programming.

====== Milestone Tasklist ======
We envision milestones, each containing its own list of tasks to be completed to be able to claim the assigned salary. 

===== Milestone 1 =====

  - **Learning:** Getting familiar with the [[http://viennamesh.sourceforge.net/|ViennaMesh]] meshing library
  - **Learning:** Getting familiar with [[http://doc.cgal.org/latest/Mesh_3/index.html#Chapter_3D_Mesh_Generation|CGALs 3D mesh generation]]
  - **Design:** Software design for a ViennaMesh algorithm which generates a mesh based on 3D images. (how does the input data structure look like? which file formats for 3D images can be used? ...)



===== Milestone 2 =====

  - **Implementation:** Wrap CGALs mesh generation algorithm for 3D images



===== Milestone 3 =====

  - **Learning:** Getting familiar with [[http://doc.cgal.org/latest/Mesh_3/index.html#Chapter_3D_Mesh_Generation|CGALs 3D mesh generation]]
  - **Implementation:** Implement a CGAL orcale for polyhedron domains with support for multiple segments.
