help!starting with opengl

Hi, i just decided to start using opengl, but i have no idea how to start… what do i need to download…?

humm, On Windows (95 OSR2, 98, NT, 2000) only a Compiler, Visual C++ is the first choice, but you can use Delphi, C++ Builder or Visual Basic, the library opengl32.dll is included with OS.

On Linux (UNIX) begin whith Mesa.
