New Stellarium features

As part of the ESA Summer of Code in Space 2011 I improved Stellarium planet rendering (here is a previous post about the project).

More specifically, the following features were added:

1) Procedural perlin noise (fBm) clouds.
2) Bump mapping with normal maps.

The improved rendering code is implemented with GLSL shaders, and requires shader model 3.0 capable graphics hardware.

Here is a video that shows the effects… (Unfortunately not the best quality video since gtk-recordmydesktop was not the best choice for recording!) Anyway, you can see the bump mapping and the clouds! :-)

Many thanks to the Stellarium development team and the ESA SOCIS organization team for giving me the opportunity to participate in the project! :-)
