KSP 2D-Tool

Introduction:

KSP 2D-Tool is, as you can guess, a tool made for ksp.

Made on GeoGebra, this tool provide you basic information on Kerbol System.

Pictures:

Where to find it?

You can find it right there: -->HERE<--

Or by clicking on the title of this thread.

You can also go to the project page to download it and/or add a comment: KSP 2D-Tool.

How does it work?

• Move the system: hold shift and use the left mouse button.
  
• Zoom: hold shift and use the mouse wheel.
  
• Time: Grab the different sliders to set the date you want, the tool will automaticaly move the planets for you.
  

Planned feature:

• Earth time: adding a switch to us Earth time.
  
• Protractor tool: a tool to see different angles between 2 planets.
  
• Trajectorie tool: an easy tool to show the trajectorie and position of your probe (without SOI change).
  
• Ttransfert tool: a tool to set the transfert to another planet at the actual time or at the economic time.
  
• A suggestion? say it and I'll see if I can do it, basicaly, everything sould be possible but more or less hard to do, if too hard, I won't, if not interesting, I won't too, else, why not.
  

Updates:

Update 2 [11/03/2015]:

-Add Moons to the Kerbol system

-Add a button to show/hide Moons

-Add a button to show/hide planets orbit path

Update 1 [14/01/2015]:

-Release of the 2D-Tool

-Add planets to the Kerbol system (not the moons)

-Add Time sliders to set the date you want to see

Few words about the project:

I staretd this project in november 2014 for my own use.

After posting it on DasValdez twitch chat, I got a good return from other people and decided to post it here for everyone.

I'm actually a french student learning maths and other stuff in a french university. By that, I mean that I won't have a lot of time to work on it and/or answer at every possible questions on the forum.

But don't worry, I like maths, physic, game and programming, so I'm not dead even if I'm not here a lot, and I really want to finish this.

Also, tools need javascript (not java dw) coding, so I need to understand GeoGebra way to think.

I also plan to do a tutorial about the maths I use but if you want to see it on your own, download the project (see above) and learn how GeoGebra and the 2D-tool work.

Little word for moderators:

GeoGebra obligate me tu use a specific licence (CC-BY-SA) and I don't have any choice on that, if there is a problem about it, say it and I'll remove my post.

This is not a tutorial.

It should probably be moved to Tools and Applications.

You're right but it's not an add-on for in-game purpose either.

Actually, it's my first post so I wasn't sure. I'm not sure I can move the post anyway, may a moderator read this and decide.

[B787_300]

Moved for you, Please try to be sure your post is in the correct Subforum

[Drew Kerman]

very cool. Can it use Earth time as well?

[Aerosfilis]

Thanks B787

I'll try to be more careful next time

very cool. Can it use Earth time as well?

Good Idea!

I'll add it to the Todo list. I think I'll work on that after implementing the moons, which I'm trying to be done for today, I've free time \o/

EDIT:

So I'm working to add the moons.

Adding them is quite easy but I think I'm gonna add a button to toggle their visbility and that ask a bit more work since it's the first time I'm using GeoGebra with script.

yea it's pointless to have them visible when you're looking at the entire system, really. Perhaps instead of a button, they only become visible at a certain zoom level

[Aerosfilis]

Geogebra doesn't use a "Zoom level" it just change the graphic window's values (Xmax, Xmin, Ymax, Ymin).

That means I have to define the "zoom".

Actually I found an easy way to show/hide with a check box without needing script.

I'll try to add an auto hide another time, when I learn how work GeoGebra object (for scripting).

Also, I'm trying to find the right value for all the moon.

The reference body change each time and it turns out KSP doesn't do that as easly as I though and the wiki isn't up to date for every value so I need to verify them...

In the end, I'm spending more time to add the moon than it took me to add the check box for their visibility x)

EDIT:

And sometime I'm just stupid so I've to redo something I though wrong but was good x)

[Aerosfilis]

Wow thanks!

That should help!

Do you know if the mean anomaly is on UT 0s or UT "When you start a new save" (9223200s) ?

Else Everything seems ok so far. Just be stupid sometime so took me a while and it's not really if I've been 100% on it ^^

EDIT:

Quick test done, seems to be on new save time.

If you know so I can be sure.

Maybe they consider UT 0s as the time at the begining of a save...

Edited January 16, 2015 by Aerosfilis

[Drew Kerman]

I don't really understand what you mean, but the UT is the orbital epoch. In other words, these are the positions of all the bodies in the Kerbol system when you first start a new game

[Aerosfilis]

ok that answer me, just got it wrong

Already did everything as if it was that so nothing to change

[Aerosfilis]

Hi everyone,

Sorry it took me so long to do the first update, and a small one on top of that.

Actually, I did a quick update few weeks after starting this post but I got some issues att the end.

I was probably too tired since I did all in one row, after couples of hours.

Anyway, I finally had time to end that.

Update 2 [11/03/2015]:

-Add Moons to the Kerbol system

-Add a button to show/hide Moons

-Add a button to show/hide planets orbit path
