I'll do that, but to be honest I dont have Orbiter installed atm., and it wont help my problem because right now I'm not concerned with gravity, except for that of the sun and there I use the value that came with the kepler function that is in use only for interplanetary transfers. Once I'll...

wow and thanks a lot for your lengthy answer... I guess I get it figured correctly eventually, right now though, I'm still struggling with it. Please excuse my (maybe) lengthy answer concerning stuff you may already know, it's just that I found over the years that formulating my problem...

:stirpot: Hmm, I'm cooking something and it's not always to my taste... I figured that the lambert solver works just fine, no inverted vectors at all. The reason why it presensts me a total delta-V 108km/s solution sometimes, is that it chooses to take the other way around (always two ways to...

:woohoo: Several days later, and a few grey hair, I have a working lambert solver, ported from the Java Astrodynamical Toolkit... unfortunately precision still wont allow for mars to catch my satellite. I am convinced however, that I have done nearly everything right. I have a few issues with...

Hi, I wrote a small simulation of our solar system using the irrlicht engine. It works very well by now. The planets are positioned by: Finding the julian day since the date of the elements (J2000) Finding the average (or mean) orbital elements of the planet Finding the true anomaly, the angle...

I just stumpled upon this thread. Unfortunately all I have to say is that I remember having a 1/2 year physics course during my schooltime entitled: "Die Physik der Musik Instrumente" which translates exactly to thread title. It mostly concerend waves (wavelengths, frequencies, interference)...

It's all fine now http://irrlicht.sourceforge.net/phpBB2/viewtopic.php?t=32299

the last time I heard the term runge-kutta was when switching dynamics solver models in a 3d application. To break it down again. There is 2 parts. 1. Planets position is calculated by the probably 'normal way' Find the day number or time since the date of the elements Find the average (or...

Hi everyone, first post... Well, I've done something with the irrlicht engine and without writing too much it's probably best to watch and quote what I've already written.. So to start with the what I try to achieve... I wanted to make it a little more realistic... So I started with...
