Check out this blog entry as a nice starting place http://blog.mikael.johanssons.org/archive/2006/09/opengl-programming-in-hask...

Thanks for this... (I too would like to start hacking around with OpenGL!)

Great, thanks. May I just ask, does ShadowMap.hs work on your machine? -- Dr Jon D Harrop, Flying Frog Consultancy Ltd. OCaml for Scientists http://www.ffconsultancy.com/products/ocaml_for_scientists/?e

It compiles fine. Runs imperfectly. The shadow map matrix seems to be off so that shadows aren't quite being cast correctly. (ghc 6.6.1 on MacOSX with a GeForce FX Go5200 if that's relevant.) Additionally the main window lacks a title bar and doesn't receive keyboard events. I've no idea if the problems are with HOpenGL or the example code.

I had a suspicion that the problem might be my forcing antialiasing on globally using nvidia-settings. This has adversely affected my own code (OCaml, nothing to do with HOpenGL). But I tried turning it back off and the ShadowMap.hs demo still displays only a black screen here. I'm on Linux with a GF7900GX but it shouldn't make any difference. As long as it works on someone else's computer, I'll keep fiddling with it here. Thanks! BTW, the other OpenGL demos I've seen are fantastic - great work! -- Dr Jon D Harrop, Flying Frog Consultancy Ltd. OCaml for Scientists http://www.ffconsultancy.com/products/ocaml_for_scientists/?e

Where should I go to get started with OpenGL and Haskell?

Take a look at Gtk2Hs, which has OpenGL bindings.

For example, see http://darcs.haskell.org/gtk2hs/demo/opengl/

The Gtk2Hs OpenGL stuff is only a replacement for the GLUT windowing tookkit. The Gtk2Hs OpenGL stuff still has to be used in combination with the standard Graphics.Rendering.OpenGL modules. The Gtk2Hs OpenGL stuff basically consists of a GL widget that you can embed into other Gtk+ windows and then use the standard OpenGL calls to render into the GL widget. Duncan
