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?
One way is to wrap the drawing action with preservingMatrix : http://cvs.haskell.org/Hugs/pages/libraries/OpenGL/Graphics-Rendering-OpenGL... (re-exported from the main GLUT module, if I read the docs correctly) This pushes the transformation state to a stack, executes the action, and restores the transformation state from the stack. More useful when you have complex scenes/subscenes/subsubscenes etc, but should work here too.
