ESA SOCIS - Flow Streams in iGlobe

[what_nick]

Hi All,

Here are notes from my interactions with Alex Babescu who is funded by ESA to work on iGlobe for 3 months (the snippets are derived from our Skype conversation).

Ok back to Runge-Kutta and fun stuff like that

Alex Babescu 16/08/11 7:24 AM

I saw the videos from the forum

whatnickd 16/08/11 7:25 AM

I was suggesting you use commons math to do this
http://commons.apache.org/math/userguide/ode.html
Look under integrators
it has a lot of tested algos there

Alex Babescu 16/08/11 7:26 AM

got it

whatnickd 16/08/11 7:27 AM

You will have to co-ordinate on the forums with Jim Miller to grab the sources for his demos
He has a homebrew runge kutta as well
start making some noise on the forums and make your presence felt

Alex Babescu 16/08/11 7:46 AM

ok, but do I still need to have my own svn branch on the nasa server ?

whatnickd 16/08/11 7:46 AM

yep
er I am confusing you ... you don't need to
options are
1: SVN branch on NASA server
2: SVN on Assembla or any other SVN host
3: Mercurial on Bitbucket or any mercurial host
4: Git on github or any git host

pick your poison

Alex Babescu 16/08/11 7:50 AM

I will need to constantly update the revision and check my code still works

whatnickd 16/08/11 7:50 AM

yep that's exactly the problem with making another SVN
mercurial or git let you create a tracking clone to keep updating
you pull from NASA svn code and them push to mercurial/git

Hi Alex, please please start using the forums, don't feel shy about putting things out in public, we will not put you down (at least not too hard) and patrick and others will not be left in the dark regarding what you are doing and our private conversation bubbles in Skype

Alex Babescu 10:11 AM

Hey, right now I'm studying for an exam I have on Saturday, I promise I'll start posting after that.

whatnickd 10:11 AM

I will start an ESA SOCIS thread, post something on it Monday, good luck in your exams

And here we are. Please help Alex out as he gets going on iGlobe, WorldWind and boards the NetCDF train. If you have any additions or criticism of my advice please post on this thread.

Cheers,

whatnick.

I have the following workflow from the OOI CI NetCDF visualisation ideation phase. I would like Alex to go as far as possible along the stream visualisation path, working on the Cyclone Yasi data or anything else we can get our hands on.

Hey,

Do you have a bigger version of that image ? I'm not sure which is the stream visualisation path.

The mercurial repository I've setup is at https://bitbucket.org/bbsc/iglobe

Hi Alex,

Here is the original pdf from which I derived the workflow - http://docs.google.com/viewer?a=v&pid=explorer&chrome=true&srcid=1vjyvTKHZGpQ3wMK8MB7en51fucg-1xIQxtMQWCids58J0gJpNr4m-lhVKU3A&hl=en . It is the manual rendering of Cyclones pipeline used by OOI, we are implementing and automating some sections of it in iGlobe.

I use this extension - http://mercurial.selenic.com/wiki/HgSubversion to track a subversion repository using mercurial, give it a try.

Cheers,

whatnick.
