[clean-list] OpenGL

[Arjen van Weelden]

Hi Jeff,

I wrote some preliminary Clean binding for OpenGL myself. You can 
download them from my website:
http://www.cs.ru.nl/A.vanWeelden/index.php?p=downloads

It uses the Win32 API to create the rendering context (written in C), 
but it shows the use of Clean's FFI to call OpenGL functions. It does 
not use callbacks from C to Clean, which you would probably like for 
more advanced programs or bindings to GLUT.

I have made an attempt to mimic Haskell's FFI in Clean to support such 
call-backs and some other useful things such as MVars, marshalling, 
(foreign) pointers, and stable pointers. It is also available from my 
website. This work has been much inspired by Diederik's work on the 
Apple platform.

Combined together, I hope that these two unfinished examples (without 
documentation, of course) will give you enough information to write 
OpenGL bindings in Clean. Although I not have same amount of time and 
energy as you do, I will try to help.

best of luck,
	Arjen
