Hi Maciej,<br><br>I was cleaning up my email and discovered that I hadn&#39;t applied your patches (to FieldTrip and reactive-glut) or even responded to you.  My apologies!  And thanks for your efforts.<br><br>I just read through your FieldTrip patch, and it looks like you changed FieldTrip&#39;s interface to use OpenGL floats instead of Haskell Float &amp; Double.  I&#39;m reluctant to shift in that direction, as I would like OpenGL to end up completely hidden behind an elegant, Haskell-centric interface.  My initial attempts to stay with Haskell types failed, due to a strange lack of exporting of some methods in the OpenGL library (preventing me from making instances for Float and Double).  I&#39;ve emailed Sven repeatedly about the issue, but his focus is elsewhere.  Perhaps if he hears from others as well.<br>

<br>I&#39;d appreciate any other ideas for getting unstuck here.<br><br>Regards,  - Conal<br><br><div class="gmail_quote">On Mon, Jun 7, 2010 at 11:12 AM, Maciej Piechotka <span dir="ltr">&lt;<a href="mailto:uzytkownik2@gmail.com">uzytkownik2@gmail.com</a>&gt;</span> wrote:<br>

Patch making FieldTrip compatible with OpenGL 2.4. Additionally<br>
strickten of requirements is added (it should be done as there is no<br>
guarantee library are backward compatible).<br>
