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.
