I only know a tiny bit of OpenGL, and I was wondering if anybody who knows some OpenGL programming could answer a question, to help me prepare. In order for me to produce these widgets in OpenGL, does OpenGL provide functions to draw 2D shapes onto the screen in front of the 3D view (like a HUD), or do these have to be drawn in 3D and anchored to the camera or something?.
