I have been programming small 2D games in delphi for quite some time, i have written many small games, and i am getting bored of them. I want to start programming in 3D and i have decided i will begin to learn OpenGL, but i don't know where to start. Can anybody mention any sites with tutorials on beginning OpenGL. Is OpenGL the same in Delphi(Pascal) as it is in C++ for example. Do I need any special files?
