Is the rendering and geographic parts of this geographic engine separate?

[WREQI]

I have done a lot of post-processing development for rendering layers in my own project. Is the rendering and geographic parts of this geographic engine separate? I want to embed this geographic engine into my project to support geographic functionality. But when I look at the example API, the three rendering part is also built into the framework. Can the geography engine part be separated and integrated into my project?

Hi, sorry for the very late reply. What parts would you want to take from iTowns? I'm having trouble seeing exactly what you're trying to separate, is it the projection math perhaps?
