Hello,
I've looked at the eve database and can't figure how the orbits visible in solar system map (F10) are determined.
I can get the X,Y,Z coords of an object in mapDenormalize but to determine the orbits, I need a third point (the center of the system being {0,0,0}) or a tilt value.
Anyone knows?

Are you searching for the sun? It's supposed to be the center point for all orbits... Wasn't the sun position with the other objects' positions? -- Pocket drone carriers (tm) enthousiast ! The Vexor Navy Issue is much more fun than the Myrmidon ! |

Knowing the position of the orbiting element and its orbiting center doesn't give you the orbit circle. It gives you the sphere containing the orbit circle, but you still need the angle (tilt) or a third point. I don't think that information is in the database dump. I believe the map gets that information from res/ui/shared/maps/cachefile.blue in resui.stuff.

You can 1. Look for star and get it's coords as basepoint. 2. Show map abstract, considering that each orbit is a multiplication of planet number by some constant.
These are two ways F11 map working and I do not know which one You looking for. -- Thanks CCP for cu<end of sig> |

F11 maps are flattened, that's not what she's talking about. If I understood correctly, she wants to be able to create a map like this.

Edited by: Jack Toad on 11/10/2007 14:35:32 Take a look to the jide's image. It looks like the third point is on coord axis. Take your X,Y,Z coords and set two of them to 0. Play with them and find the correct combination.
Or maybe the rule is: the point is on the nearest axis

Nothing ever moves. Just randomize the orbital elements within the constraints.
You can probably greatly simplify things by assuming that each object is at apoapsis. Pick random numbers for eccentricity and adjust them if necessary to keep the lengths of the semi-major axes increasing monotonically with orbit number.

Use mapDenormalize.orbitID to find the item it orbits around (star for planets, planet for moons and belts, moons for stations etc.)
Also, mapCelestialStatistics.eccentricity looks like it's worth looking at; might be used to work out the tilt rather than actually being eccentricity (all the orbits on the solarsystem map I've ever seen look circular).
