trouble correctly identifying 2d (x,y) coordinates.
Hi, I have loaded a font and I would like to display it at (x,y) on the screen efficiently. This is good for displaying FPS and other info. So far, the two ways that I''ve explored are:
1) Change screen to orthogonal projection and use a simple glTranslate(...).
Con: Need to change type of projection, might be slow if changing from perspective/orthogonal projections back and forth every frame.
2) Using perspective project, use glRasterPos2i(...).
Con: Need to do funny calculations that take into account view angle, width and height. I don''t know how to do this
Which is a better way of approaching this problem? Can anybody give me any hints on how THEY did this?
