If you or your corporation is a fan of bookmarks, then you'll be happy to know you can now access the details of all of your bookmarks with the XML API. For more details, see here.

I hope someone makes a website with a mapping of your own bookmarks that you can zoom in / out of, would be cool :D.

Since the API is one way is there a practical way to transfer BMs to other people through the API? Like an import method into Eve from the xml format?

Since that would mean the ability to create your own bookmarks out-of-game I would guess no. Imagine automatically making deep safes, perches on gates, insta-undocks on stations you've never visited, etc.

Awesome!

I once asked this... https://forums.eveonline.com/default.aspx?g=posts&m=5246900#post5246900
And now is the time to ask again..

Can we somehow get the inclination of orbits within a solar system?
So we can draw solar systems with the orbits they have in-game - http://i.imgur.com/ZrsigmJ.png
Last time I checked that information wasn't included in the SDE or anywhere else.

Let P and S be celestial bodies where P orbits S (planet/sun, moon/planet, etc.). Let V be a normalized directional vector from S to P. Let C be a circle (y = 0.0) whose radius is the Euclidean distance between P and S. Let Q be a quaternion whose x, y, and z components are the cross product of (-1.0, 0.0, 0.0) and V, and w component is the arc-cosine of the dot product of (-1.0, 0.0, 0.0) and V.

P's orbit around S is C rotated by the quaternion Q and translated to S' origin.

Hope that helps.

Thank you for the reply!

Unless I'm mistaken, it still doesn't help with my issue tho.
I will get a possible orbit, but in many cases not the one displayed ingame.
E.g. for Rens & planet 2 I would get an orbit where the planet is at its highest y value. But this screenshot shows that it actually isn't that way ingame.

Maybe I can phrase it differently:
Orbits in Eve (on the ingame map) are circles on a 2d plane in 3d space. So to define a plane in 3d space we need 3 vectors: a location vector LV and two lineary independent direction vectors DV1 and DV2. In our case, LV would be a null vector, since the sun is at (0,0,0) within its system. Now we can use the vector from S to P as DV1.. but we still lack a DV2 to span the plane on which be draw our orbit.

This is how the client computes the orbits for the map. In your example, we begin with a flat circle (plane) centered at the sun (0, 0, 0) and y = 0.0. We then rotate that circle using the quaternion I described above, and that's the orbit shown in-game.

Certainly there are ways to compute other plausible orbits from the given data, but that's the method being used.

Ah, alright!
Seems like I didn't think your first reply through :S

I'll be working with that, thanks! :)

let me guess, pos code?

how to fix eve: 1) remove ECM 2) rename dampeners to ECM 3) add new anti-drone ewar for caldari 4) give offgrid boosters ongrid combat value

thie orbital setups in eve have always bugged me a bit. orbits being circular for everything, and especially the fact that planets and other celestials (including anchored obects) never *move*, at least during downtime. yes I realize that would be a monumental task to do an update of all the celestial and anchored objects in the downtime every day... just saying it bugs me.

I mean... at least move celestials that have orbital periods that would significantly change over a 24 hour period... close in planets, moons, stations and POCOs for example. planets and other objects out on the edge of a system at dozens (or hundreds) of AU out wouldnt move much at all over the course of the game (though moons might).

would that make bookmarks a royal pain? yes. but it could also raise the game to another level - CCP has already nerfed fleet bookmarks, it could be said that making celestials MOVE would do the same thing just by virtue of making long-term bookmarks useless.
