XCTruck3D _Truck 1.0

A truck/car simulator, with realistic physics and oldstyle graphics: it displays pixels throught the X Window System, while the 3D graphics is done by the program itself without external libraries. The environment is a hilly terrain:total freedom to drive around.A remake of the classic "Terep 2". Written in the C programming language: although the code is 40 pages long, it's simple. CTruck3D _Open runs on Win too.Trailer can be detouched pressming 'm' so to drive a normal car. There's an OpenGL version too: see the CTruck3D _Open project, and an ASCII-Art version too (Term_ CTruck3D): theese have Windows versions too. This is also a good dydactic software because the code is easy to undersand,and the drawing procedures and physics sim procedures are written from 0 so it's clearly visible and understandable how a complete 3D game is done in C, starting from a blank page of Gedit (any plain text editor). Only basic knowledge of C is required to understand it and/or modfy it. 
XCTruck3D _Truck is a completely free software. You can free download and use it as long as you like.
