SOCiS 2014 is over

First of all I would like to say thank you to ESA and to Marble for this great opportunity. It was fun! I would like to say thank you especially to Torsten Rahn who guided me through the summer and to other people who helped me. I also want to thank to Maxime Perrotin who organized this and to everybody who helped in it. And now, about my work in the summer:
As you may now I worked on a new feature in Marble, supporting panoramas. I think everybody can imagine what this means. You can view for example panorama photos taken by rovers on Mars in Marble. Here is a little showcase:



But if you want, you can use it to other purposes too:


And now more technical informations about my work. I can split up my work to two big parts: reading, exploring, understanding the code and writing, plotting, debugging the code. A lot of time I have to refactor my code because to be more similar in style and in idea to the existing codebase, but I learned a lot from it.

In the summer I worked on the following things:
  • KMLs can be used with <PhotoOverlay> tags. Marble can handle them (on any planet) and mark them on the map with an icon specified by its style.
  • You can click on these marks, it will cause a popup like what will appear when you click on a placemark but it will contain a little preview image. This popup has other special abilitys too. It comes with a new button in the toolbar, which will create a new session for you. This will display your image. So just search for this button:
  • I meantioned before it will open a new session. This was an other fruit of this summer. I have put down the basics for session handling so you can return to your previous session after viewing a panorama. Just search for the "Close Session" button on the left. I'm sure more improvements will arrive in time.
  • And don't forget an other importent thing: when you opened a panorama you can open a new KML which will place its content in your panorama so you can achieve an effect like in Google's Streetview.
I still have more ideas how to improve this, so in the following months I know what will I do.

SoCiS Final Status Report - Cleaning

After a great summer I would like to share with you what I worked on. 😊 But before that I would like to thank everyone who made that possible. Thank you Shane that you was my mentor this summer and guided me through every problem. I definitely learnt a lot and it was fun. 😃 Tnhks for the SunPy community to take me in and for their every help and I also want to thank ESA and Maxime Perrotin to organize this great program!

And now, we can check out the results! 😉

You can find the documentation in the project wiki  and the theoretical background in my previous posts. Now I want to concentrate on the actual usage of the library in case of an actual problem from A-Z.

Lets say that we have a fits file with several RHESSI visibilities and we would like to process it. First we would like to get the xrayvision module (I assuming that SunPy is already installed).

To get the module we have to check it out from GitHub:
git clone https://github.com/sunpy/xrayvision.git
After that we have to i…

It is official, Marble is coming to Android

First, I would like to announce, I have been chosen as a Google Summer of Code student and my task is to provide a working version of Marble on Android at the end of the summer. This is a very important for Marble, because Marble currently only available on Desktop and on same rare mobile platforms (Maemo, MeeGo) but on the most widespread platform (Android), not. It is very sad because it is more and more common in education systems that they use TVs, tablets and smartphones with Android so they can’t use Marble as an educational tool. The supported Android platforms will be Android v2.3.3 (API level 10) and higher, because it will be ported with Qt for Android.
The work has been started. Stay tuned...
