@nyrath It's also pretty easy (and instructive) to write these sort of short route finders yourself

@nyrath Though I should note that my T2300 map incorporates Gaia DR2 data as might be seen by the route finding:

@nyrath I have the Hipparcos catalogue incorporated as well. For me the significant work was in removing false positive detections in Gaia DR2 (and there were a lot), then merging and de-duping the set with the other common sets. Your empire-spheres seem to be in various orientations - does this imply that each polity uses its own coordinate frame?

@nyrath I've done that too (origin stars sending out colony ships then a world population growth model, followed by trade simulation), and I need to pick it back up as it's only partly complete. I have a frequent context switch problem.

@nyrath Mathematica has a bunch of graph-related functions including community finding that I've used for something similar ( https://reference.wolfram.com/language/ref/CommunityGraphPlot.html?v=14.0 ) , though it might not be the same implementation as the paper (which I'll have to read later today).

@nyrath For Traveller, incidentally, I'm not sure what the meaning of borders actually is. An entire fleet could move through an enemy controlled system - jump in, refuel in cometary halo, jump out, before light speed propagation delay of knowledge of the fleet's presence even reaches the mainworld.

@nyrath In Traveller one of the first things that is said about the setting and is fundamental to the game is that information cannot travel faster than light, except via jump drive, that combined with a lower limit on the size of a jump drive (for 100 DTon ships) puts some of the concerns of your site into play. In practice for me, though, it usually means that a mainworld might be controlled and defended, but the entire system cannot be.

@nyrath It might be, perhaps, a reason to break down and write an Apple Vision Pro app.

@Hcobb @nyrath I think MM might have even intended that jumps are always mainworld to mainworld, which would also eliminate the system defensibility problem, but later editions of the game and supplements clearly allow for jumping to non-mainworld positions.

@nyrath @notasnark Though admittedly niche, the nice thing about a 3d star map is it allows for you to plot the sky from an arbitrary world within the setting (here, for example, Aurore with correctly-positioned stars, camera pointed toward Orion). That can help with setting immersion.

@Robert_Brandt @nyrath I have 1.6 million from DR2, but it's cumbersome to load and work with. I do, however, plot sky charts with it: Here's the path of Borisov (not quite accurate, it was my own orbit determination) - but each background small-point is a Gaia DR2 star.

@mcnees That looks fairly similar to the example that's in the wolfram demonstrations project: https://demonstrations.wolfram.com/ElectricFieldLinesDueToACollectionOfPointCharges/

@mcnees also don’t underestimate the help you can get if you have a support contract, even things like programming help.
