R: Re: [pgrouting-dev] pgRouting render

[Stephen Woodbridge]

Daniele,

as a follow on to my previous response, I would recommend starting with 
the pgRouting tutorial if you haven't already worked through it:

http://www.google.com/#q=pgrouting+tutorial
http://www.google.com/#q=pgrouting+tutorial+foss4g

so you can understand some of the pieces and how they fit together, then 
you need to decide how you can use these pieces in your desktop 
application or if you need to replace one of them with something better 
suited for your application.
