I've searched and searched, and I can't find a way to calculate transversal velocity. The tracking guide I have bookmarked is no longer on the server apparently, maybe they're moving it to the wiki, but anyway, I can't access it. I seem to remember that Transversal of Ship A relative to ship B is Velocity Vector of A - Velocity Vector of B. Is that it? It make sense for it to be something like that. However, transversal is a scalar, AFAIK. So how does that work? And if transversal isn't a scalar, how do you input the transversal parameter into the tracking formula (http://wiki.eve-id.net/Tracking) So I think I'm missing something in the formula. Also, what happens when two ships orbit each other, in terms of direction?

Why would you want to calculate it anyway? The game does it for you and displays the transversal velocity on the screen. Or you could just ignore 'transversal' and use 'angular' on your overview, which gives you the required info in rads/sec, which is what your turrets track in anyway. Just a thought.

Velocity is vector. Speed is scalar (the magnitude of velocity). Transversal velocity is the component of the relative velocity between the two ships that is perpendicular to the line passing throu them.
A more usefull value to watch ingame is the angular speed (often misnomed as angulat velocity) that is measured in radians and can be directly compared to the tracking speed of the turrets.

Exactly what I wanted, ty.

You can get all of these things shown in your overview. Actually knowing your transversal is pretty useless afaik. Angular velocity determines turret tracking and overall velocity determines missile effectiveness.

I know, it's just to compare fits without testing them out in game I gotta know, because angular depends on transversal. Plus, the game displays angular only for him relative to you, not the other way around.

Edited by: Lear Hepburn on 15/03/2009 17:47:53 Well angular=transversal/range, basically. I've managed to plug the whole thing into Excel in such a way that you put in your max speed, your mass and your inertia modifier and it'll tell you the speed you'll get at certain ranges, and the angular you get at that range. The formula is: r = A.m.v^2 / (SQRT ( Vmax^2 - v^2 ) x 10^6)) Where: r = orbit range A = Inertia Modifer m = mass v = speed Vmax = max speed
The 10^6 is the constant you need to divide A by to make it meaningful in this context.
I then use the results in the app I linked in the other thread to check them before using them.

In EVE the angular velocity is the same for him relative to you and for you relative to him. Despite what you see graphically, tracking does not account for ship orientation. Therefore both opponents need to track the same. That's why the angular speed compared to your turret tracking speed is what you want to keep under control. And that's why you want to be able to track better then your opponent: so that you can get an orbit that gives an angular speed that is lower than your tracking but highter than his.

Ah, I thought it wasn't the same for both. OK, ty.
