Open Source C Simulation Games for Linux

Stellarium renders 3D photo-realistic skies in real time with OpenGL. It displays stars, constellations, planets, nebulae and others things like ground, landscape, atmosphere, etc.

A UNIX/Windows/Linux remake of the DOS-game "stunts", providing modern features like openGL graphics, 3D sound and internet multiplaying. Design your own tracks, choose your opponents and try the most spectacular stunts you've ever seen.

CTruck 2D is a 2D, oldstyle, physically realistic 2D truck game. Predecessor of the CTruck3D vehicle simulator series. I wrote it from zero in C (+OpenGL&GLUT). It has ascii-art and nice graphics version, and a special funny version It's a very basic thing: there are free rigid bodies and springs with strong attenuation/damping. It's very simple and very short code, and collisions of bodies with ground are good and stable. A good simulation of this kind, however requires Lagrangian method. I proposed the Lagrange_motocross as an alternative of this kind. The code is not much longer but the it's overall more complicated, and collisions are a bad issue.

Elite Zero is a simulation game in the broadest sense of the word. The aim is to simulate natural and economic processes while providing an enjoyable game. The idea comes from the "Elite" series by Ian Bell and David Braben.

SSF aims at providing an easy to use and efficient framework for physics sim & visuals in small scientific simulations in real-time, as well as games, which are inherently real-time applications.
