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! ๐Ÿ™‚

Many thanks to the Stellarium development team and the ESA SOCIS organization team for giving me the opportunity to participate in the project! ๐Ÿ™‚

Stellarium planet rendering improvements.

Here are some screenshots of the new planet rendering in the Stellarium software, implemented as part of the European Space Agency Summer of Code in Space. I implemented a bump mapping algorithm (using normal maps) in GLSL shaders and I integrated it into the Stellarium application (C++). The planets are ellipsoids. There are still many different things to be done for further improving the project, these are just some samples.
