PS. I've investigated existing APIs and I'm not seeing anything that looks useful. Lots of support for drawing lines and arcs and so on, but not for plotting individual pixels.

I highly recommend OpenGL. Even if you are just filling texture maps for now, you have a future proof way to do far more sophisticated graphics.

...just... the irony of using OpenGL to write a software ray tracer. ;-)

Oh, and the irony of using OpenGL (an API of unimaginable complexity) just to write pixels to the screen. Isn't that kind of like using a thermonuclear device to crack a nut?

OpenGL is used as a pixel-plotting mechanism relatively often. You wouldn't be doing anything new if you did it that way. I say someone binds SDL[1]. (If it hasn't been done already.) - Jeremy [1] - http://libsdl.org

Interesting! I just wanted to reply (although Andrew Coppin must have unsubscribed by now...) that I have an application that plots pixels using OpenGL (it's actually not that hard, just visit the new Haskell OpenGL page, and look at the examples given, e.g. http://darcs.haskell.org/packages/GLUT/examples/RedBook/Image.hs). But the SDL stuff seems easier... Thanks, Peter Verswyvelen Roel van Dijk wrote:

I use those SDL bindings to plot pixels with OpenGL and play with 3D stuff in Haskell. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

I tried this library on Win32. A very nice initiative indeed. Currently, I found the following problems: - as mentioned in the WIN32 readme file, the library does not seem to work with GHCI. Firstly, it seems to look for incorrect DLLs. When I copy SDL.DLL to both SDLmain.DLL and SDL.DLL.DLL, then GHCI starts the Test app, but it hangs as soon as the window is displayed. This behavior is similar to what I initially had with SOE/Gtk, but that got fixed in the latest release of Gtk2HS. Maybe the author of Gtk2HS (Duncan?) and HSSDL ("lemmih") could exchange information on how to get it running under GHCI? - the documentation contains links to non-existing files. I had to rename Graphics.IO.SDL.<name>.html to Graphics-IO-SDL-<name>.html, then the docs worked. Cheers, Peter Verswyvelen Luke Palmer wrote:

YEEESSS!! W00t11 I've been looking for that for a long time. I get so sick of glut... Thanks.
