Good morning,

I am trying to draw a object or a text like data information close to the top left corner of my window. The problem is that I dont want that object or information be affected by the zoom of the camera. When I click to zoom, I lose the values or the object drawed in the mentioned place.

This kind of thing (often called as "HUD") is usually done this way:

Draw function:
[font="Courier New"]


SetupHUDProjection(); [color="#2e8b57"]// usually with glOrtho set to match the window size
SetupHUDModelview(); [color="#2e8b57"]// usually set to identity.

[font="Arial"]This way the HUD (texts, GUI, minimap, radar, whatever) won't be affected by transformations (zoom, rotate, pan, whatever) and will always be (if you want it to be) pixel perfect.[/font]
