[Qgis-developer] [AniMov] AniMove toolbox

SEXTANTE "passes" all data to backends using files, in a way that is
transparent to the user and the developer. Basically, it passes the
datasource filename and let's the external app open and process the
data. But, it is transparent and convenient to use because if the data
is in a format that the external app does not understand, it will save
the QGIS data to a new compatible file and pass the path to that new
file. That allows to connect you app with GRASS data, WFS services, or
any other source that QGIS (but not your external app) can use as
input. In short, much cleaner and easier for you to implement :-)

The philosophy of SEXTANTE is to make it easier to implement
algorithms, taking away all the data handling and GUI stuff and
letting you concentrate on the algorithm itself.

You can use the current R implementation in SEXTANTE to make a new
script (or several), but you could also, with a bit more effort,
create your own algorithm provider extending the R one, which would
give you more control. Please, ask me if you have questions.

Hope this helped to give you a bit more insight into how SEXTANTE works
