Basically i have my 3D game world and a 3D compass model (which rotates as you move the game world around, and therefore allowing you to always know which direction you are facing).
The problem is i need to ‘attach’ this 3D compass to my screen so it is always in the corner of the viewport, regardless of where you point the camera. Something similar to drawing my menus in 2D/ortho mode would be nice. Or am i going to have to use some complicated maths?
Thanks in advance
