car race in 3D with C#

Yesterday I was looking at the demo I published in my last article, the asteroid demo, it had a good acceptance because it was made in a very simple way and today I will do the same. This article is a simple straightforward car race game trying to contain the minimum amount of lines of code (LOC). There are 3 cars that begin in a start line, they random change their speeds on the race and the race ends on an end line, quite simple. The user can follow the race with the keys W(forward) S(backward)  and can change the camera takes. At the end of the race a message is shown telling which car was the winner and you are able to reset the race and start over again. The car race is a simulation and the user can’t take control over any car.
Any suggestions to the code let me know, here is the download link

  4. Hello
    The class Winapi its to communicate .NET with windows API

    [DllImport("GDI32.dll")]
    public static extern void SwapBuffers(uint hdc);

    This function calls SwapBuffers contained in GDI32.dll this is unmanaged code. The interop namespace handles this task.
    About SwapBuffers OpenGL doesnt draws directly on the screen instead it draws to a buffer and then SwapBuffers brings it to the screen. This is a techique used to avoid flickering
    If you have any further question please dont hesitate to ask.
    BTW it will be helpful if you become a follower of my blog :)

    1. Tao.Opengl is an OpenGL wrapper it allows programers to call opengl functions from .NET

  6. Hi there,
    excellent work. But I have problem when I load my own 3DS model to your project as "Invalid magic in 3ds file header: 0x00002023" at ContentManager.LoadModels(); in mainForm.cs. What could be the reason? thanks and regards.
