Hi all,
I'm having a lot of trouble using renderString from Graphics.UI.GLUT.Fonts. All my attempts to render a StrokeFont have so far failed. Using a BitmapFont I can get strings to appear but they demonstrate the odd behaviour of translating themselves a distance equal to their length every time my displayCallback function is evaluated.
My requests are: * Does anyone know how to keep the position fixed? * Are there any good examples of (working) GLUT code available on the web, I'm finding it very hard to make any progress at the moment. Certainly not at Haskell speed :(
I am using the following code:
import Graphics.UI.GLUT main = do getArgsAndInitialize createWindow "" displayCallback $= update actionOnWindowClose $= ContinueExectuion mainLoop
update = do clear [ColorBuffer] renderString Fixed8By13 $ "Test string" flush

I had a similar problem with stroke fonts. Try scaling by a low number (such as 0.01) and see where that gets you. The problem was it was rendering them at a size much bigger than my coordinate space that I just couldn't see them. I'm not convinced you need that $ there either but I don't suppose it hurts. Charles
