Some Tutorials : DirectX, OpenGL
I wrote these tutorials back in 2004, when I was in my 4th year of graduation.
First version of DirectX 9.0 released in December 2002. There were not many tutorials available on this topic back then. After the publish of these tutorials I got so many positive feedbacks from different part of the world, which was really encouraging.
