I start to work on WinBasicGL around three years ago (2004) with the purpose to 
make a simple compiler to use with OpenGL APIs. I have written it during my free 
time and is not designed to compete with commercial products, however,
as shown in examples, WinBasicGL is sufficiently powerful to allow you to build
simple 2D/3D graphical applications (demos, games, .. etc.).
The version 1.x is free and everyone can download and use it (license). 

The compiler:

The version 1.x support only a sub set of the standard basic language and not 
all OpengGL 1.1 APIs are recognized by compiler (language references).

Requirements:

 - A Windows operating system (I have tested WinBasicGL only on W2K and WXP). 
 - A 3D accellerated video card. 
 - A decent system.

The next steps:

I'm working ...

1) to write a big DLL which exports a lot of functions and commands (2D, 3D, sound, ...etc) 

2) to improve the compiler by adding:

 - other BASIC construct like "Select/case", "For/Next", "Repeat/Until" etc..
 - new fuctions about event handling (Keyboard, Mouse ..)
 - more IDE functions and options

I hope to release the new features in a few months. 

To keep alive the project, the web site, the domain and so on..;
I will ask for a small fee for the next versions of WinBasicGL.
