how to keep a GUI on-screen without moving or resizing it according to camera movement

Hey i'm trying to make a GUI lib with SFM开发者_如何学CL, and everything's done except one problem: Making the Interface stay still even when the camera moves or zooms in.

This would be easy to fix if zooming wasn't possible, but zooming out means scaling the contents of the Interface up, which causes it's text/images to become blurry.

Does anyone have a way to get around this issue? (preferably only using SFML, but if i must i can add OpenGL stuff....)

Stop using the same camera and perspective matrices for your GUI as you do for your scene.

In the case of SFML apply a different view, then restore the old one.
