Fixed image when panning

So this is a question regarding layers.
I want to have a fixed axis placed on my graphic even when I pan around. How would I go about doing this? Any suggestions would be appreciated.

On your graphic? What is your graphic? A quad? You mean your screen? You want something that stays fixed in your viewport? Does it need to be in 3D? If not…

// render scene

// get ready for 2D projection
glDisable(GL_DEPTH_TEST) // if on

// render fixed axis (with depth buffer off)

Thanks stratton,
I’ll give it a shot and let you know how it goes.
