    skunks

    3D driving simulation based on Open Dynamics Engine

    Sour*eforge.net has become inaccesible to me because of Cl*udflare. The latest version of skunks is on my site: https://matei.one/. 3D realistic driving (not racing) simulation with software rendering, based on Open Dynamics Engine (which is included in all *.tar.gz files so it doesn't have to be downloaded separately). 10 cars (all electric) and 16 tracks are available in version 5.1.0. Cars and tracks can be easily created and modified. Only SDL 1.2 or SDL 2 required besides standard C library. GNU/Linux and Wind0ws executables are available. If using GNU/Linux and SDL 2, it might be necessary to add -lpthread in the comp file, at line 2.
