Hi!
I have a 320X240 full screen and a bitmap of 16X16 size.I want to texture map the bitmap on a quad so that it fills exactly 16X16 pixels but I don’t know how to make a 16x16 quad.I know to make vertex only vith vertex{2,3}{v}{sidf}.Is there a way to work around?
Thanks to the people who have helped me!
You can switch to orthographic viewing, then use glVertex2i() to draw your quads.

Can you be more concrete please?I need an example.

An OpenGL application should never try to refer to certain pixels on the screen and there isn’t really a way to do so. You can, as Anitox said, use orthographic projection, but OpenGL is entirely resolution-independent. Have a look at glDrawPixels() and glBitmap(), maybe they solve your problem.
