Henk-Jan van Tuyl commenting Andrew Coppin
... (about HOpenGL and H.Platform) ...
Uh... yes, you might be right about that. However, AFAIK you still need something with which to create a rendering surface in the first place. (Not sure if HP includes GLUT...)
As you can see in the HP documentation at http://lambda.haskell.org/hp-tmp/docs/2011.2.0.0/index.html , both OpenGL and GLUT are present.
Or simply download and execute the examples before raising doubts... (the Haskell translation of the NeHe tutorials, etc.) No need for speculation. Now, I have a personal pedagogical comment. A few months ago I gave to some 30 students an assignment (a family of, with freely chosen variants). A long one, to complete in 2 months or more, and the subject was - the implementation, coding and running some nice 3D scenes with HOpenGL. I teach Haskell for years, usually the projects, which should be "applied" are devoted to some exercices in AI / games, compilation, text processing, graph manipulation, lazy numerics, etc., you know the song. This time I decided to propose something more visual. The results? A true DISASTER! They did "something", all of them, and all their realisations were the nec plus ultra of mediocrity... Since my students were as clever and laborious as always, and I didn't drink much vodka during this process, I asked them what happened? The short "standard" assignments went smoothly as always... The answers (concentrated) were as follows: The OpenGL bindings in Haskell are hardly "functional". You make us sweat with generic functional patterns, laziness, exquisite typing, non-determinism monad, parsing tools, etc., and then you throw us into this ugly imperativism ! Nobody liked your assignment, it was no pleasure for us, and our results are the consequence thereof. Where is Haskell?? Of course, we had to execute the typical syntactic gymnastics, but without understanding the functioning of all those "variables", and other stuff relevant to the stateful OpenGL engine. Perhaps, if we had before a semester of OpenGL, and at least two months of a true course/tutorial (not your pseudo-tutorial on the Web...) we could be more productive. That's it... I don't want to generalize, but there is a huge work to do in this context. All the best. Jerzy Karczmarczuk Caen, France
