Option for spacing link origins #10

Closed dominicfollett closed 5 years ago

@skieffer Is there an option that allows you to space the originating/terminating position for a link?

E.g.

For node 10, I'd like those links to be spaced further apart across more of the box's real estate.

I'm using your fork of Adaptagrams C++ library.

For the final routing, HOLA uses a Router, from libavoid. This has a parameter called idealNudgingDistance that would control the spacing you want. At present there's no way to set that parameter in the Router that HOLA uses, so you'd have to hack it. Look somewhere around line 410 in hola.cpp. I think the default value is 4 (pixels), so try setting something a bit larger. Might look something like this:

ra.router.setRoutingParameter(Avoid::idealNudgingDistance, 8);

Gotcha, thanks! Maybe I can submit a PR once your fork is merged.
