Thanks for stopping by. So here is my little gravity application. It’s very early in development so don’t be surprised to find bugs, as with all development projects I know how to use it to avoid problems. Click on the image below to launch the app (you’ll need flash player), you can download that from here : http://get.adobe.com/flashplayer/ .
Here’s a brief tutorial of how to use it. I’ve defaulted some of the values so that it starts at 3% zoom and a large enough orbit line thickness so we can see what’s going on. Before you do anything, turn on the “Show Orbits” check box. Then hit the Load button. This pulls in the starting values for planets.

Check out this post for more details on how to use the application : https://danthaiwang.wordpress.com/2010/11/05/pldm-orbiter/
If you’d like to play around with the starting values (that get loaded in via XML) then download the application from here : pldmOrbiterApplication.zip Inside the zip you’ll need to run the index.html. You can manipulate the starting data by editing the XML in the folder ‘saveddata’. Once you’ve saved the file ‘Remove All’ bodies from the stage and then press load again to see your changes.
My goal is to try to get tiny planets orbiting from a long distance away.
Let me know your thoughts. dan@pldm.co.uk
