Thanks! I'll dive into it, Hope your talk is filmed! Any plan to come to EuroScipPy? Guillaume Le 06/04/2015 11:10, Tiago de Paula Peixoto a écrit :

Hi all,
I'm using graph-tool to model mesh-like elements (cells in a biological tissue). As the model evolves towards more complicated geometries, I'd very much like to access some of the underlying GCAL objects not ported to graph-tool (such as faces). For now I rely on a somehow cumbersome dual propertymaps/pandas data manipulation.
I was wondering how this could go, but don't know from which end I shell read the code in graph-tool. Also would some kind of plugin architecture be possible (i.e. compiling the relevant Cpp bindings as a shared object compatible with graph-tool)? It is entirely possible to write such C++ plugins for graph-tool; I do it all the time for my own stuff. However, this is still entirely undocumented.
I plan to write this documentation, with a least a simple example, soon. (I will give a small graph-tool tutorial talk in the next NetSci in June, and I want to have this done by then.)
In the mean time, you can peak at how the PageRank code is implemented, which is fact a rather complete yet not too long example of how to extend graph-tool:
The C++ part:
https://git.skewed.de/count0/graph-tool/blob/master/src/graph/centrality/gra... https://git.skewed.de/count0/graph-tool/blob/master/src/graph/centrality/gra...
The python part:
https://git.skewed.de/count0/graph-tool/blob/master/src/graph_tool/centralit...
You need to know how to use the BGL and Boost python.
Best, Tiago
