GLOBE_3D, a free, open-source, real-time 3D Engine written in Ada, based on OpenGL, is now hosted on SourceForge. A unique feature of GLOBE_3D is that it is unconditionally portable. This you can use exactly the same sources for all possible target platforms (no tricky conditional compilation). This is possible thanks to the combination of OpenGL and Ada, both of which being designed for total portability. The most recent version now offers collision detection.
