Hello all,
My name is Sathya, and I would like to contribute to cl-opengl.
I use cl-opengl on OSX to play with opengl in lisp. I use it by changing the library from freeglut to apple's cocoa-based glut framework. (Although I'm sure I could use apple's X11 + freeglut, X has given be trouble.)
If there's anything in particular you would like help with, I'm here. (It could be anything from OSX based testing to simple bug fixes.)
Thanks

That GLUT will call exit() (and kill your Lisp) very often, doesn't that annoy you? Hey, you could port freeglut to Cocoa (or is it Carbon?), that'd be nice. :-)
Yeah, it annoys me a lot. I'll check if anyone has any prior work done in that direction first, but if not, I'll look into it. The problem is I have little cocoa/carbon experience. Time to learn I guess.

I am sure the thing that stopped me was not being able to call NSApplicationInit()... I did manage to get something going but it kept dropping out with an error, which, on looking it up said I had to call NSApplicationInit() but my CFFI experience is limited and I couldn't work out how to do it.
I looked at Verrazano as well but in the end time pressures made me go for X11. It just worked, I had to make a small change to get it to work on an intel mac though if I remember I just modded the library.lisp file a bit. My finally chaotic glut def looks like:

which, removing the chaff leaves this, I added the :x86 to make it intel friendly!

It has something to do with the functions in interface.lisp, I believe. (I can't remember for sure, but I THINK, if you call glut:init twice using apple's cocoa glut it gives you that NSApplicationInit() error.)
All I had to do (I think, it's been a while) was to use that (:darwin (:framework "GLUT")) line in library.lisp.
My sample code is attached, Sean, although it won't run as it is, unless you install cl-arcball. Remove all of the cl-arcball code and it should run for you. (Or, since I'm also attaching my cl-arcball asdf-install library, you can just asdf-install cl-arcball 0.1).
Note all of the cffi foreign function and foreign type conversion and callback stuff. It's not hard once you read through the code, in my opinion.
