I put the result of running

/System/Library/Frameworks/OpenGL.framework/Headers/OpenGL.h
/System/Library/Frameworks/GLUT.framework/Headers/glut.h

through OpenMCL's interface translator (on an OSX 10.2 system) at:

<ftp://clozure.com/pub/darwin-gl-interfaces.tar.gz>


That's hopefully adequate to enable people to do:

(use-interface-dir :gl)

and refer to OpenGL/GLUT constants and functions via OpenMCL's FFI.

I don't know enought about OpenGL to know if that set of translated
header files is complete; it seems to be about equivalent to what
OpenMCL's provided for GL under LinuxPPC.

That's a ways from having a good lisp interface to OpenGL, but it's
presumably a necessary step.

What needs to be done in order to get something to actually appear
on the screen seems to depend on R'ing TFM; I'll try to do so soon.
