You know glVertex2f(), glVertex3f() and glVertex4f() functions have upper and lower boundaries of -1.0f and +1.0f.

And, can you tell me what boundariesglVertex2d(x, y);
glVertex2i(x, y);
glVertex2s(x, y);x and y parameters have for the functions above?

And one more thing... What is the 4th parameter of glVertex4?() is for?
