Hmm, no reply until now. :-(

A related question:  I plan to let "my" students write some HOpenGL based 
applications in a practical course whose intend is to train them in 
functional and logic programming.  One of these applications should simulate 
a flight over a landscape whose surface is modelled via fractal brownian 
motion.  So the program needs to display a rather large amount of geometric 
primitives and needs to do this rather fast because the thing is animated.  
Now my question:  Is Haskell in conjunction with HOpenGL overstrained with 
this problem or can I expect the application to run fast enough to not make 
the students laugh about Haskell's speed. :-)  Of course, the program should 
be run only on graphic cards with 3D acceleration.

I'd be happy about quick replies. :-)

Best wishes,
Wolfgang
