Dear Babtiste,
nice, that you have some progress.
I am currently working on a new user interface for KiteSim based on QT and QML.
For QML (similar to JavaScript) a 3D component is also available:
http://blog.qt.io/blog/2015/06/05/porting-three-js-code-to-canvas3d/On the one hand this would be nice to integrate into FreeKiteSim, on the other hand
the current approach (doing everything in Python, also the 3D visualization) has
the advantage that students only need to learn Python and can write new simulation
and visualization code.
Best regards:
Uwe
