Solar Visitor :: The Source
Warning: installing Ogre and its dependencies is not an easy task. Depending on where you put the libraries and media the text configuration files plugins.cfg and resources.cfg need to reflect this. It is much easier to make do with the binaries.
That said, if you already have Ogre installed then be encouraged to build from source.
This release is made for Ogre 1.2.5. A Makefile is provided for Linux builds.
The program uses 3D objects (spheres with textures) made in Blender. The binary releases contain these objects in Ogre format as .mesh files. The package below contains the .blend files but you will still need a binary release to obtain the .png textures.
Ogre is available on the most common platforms - Windows, OS X and Linux. I would be interested to know how it goes on the Mac.
