I am trying to figure out how I can determine my current absolute location after I have performed a translation and rotation. I am in 2d ortho mode, so hopefully this should simplify things…I’m thinking this may be to do with matrices but I don’t know where to start.
Also, Ortho mode has nothing do with it. You should be applying your translations and rotations to your ModelView matrix, not your projection matrix (i.e. after calling glMatrixMode(GL_MODELVIEW))
