I use lispbuilder-sdl with cl-opengl, and it works pretty well. Thopter (<a href="http://code.google.com/p/blackthorn-engine/wiki/Thopter">http://code.google.com/p/blackthorn-engine/wiki/Thopter</a>) was built this way, and runs well on Mac as well as Windows and Linux.<div>
<br></div><div>I don&#39;t think you should really need much a tutorial, since the cl-opengl API is pretty much a direct mapping to the underlying C API. But the lispbuilder-sdl documentation does have example code for getting an OpenGL window set up:</div>

Hi Schell,<br>
<br>
A lot of people also use some other library to create the window, get<br>
the opengl context, do user input etc. Of course GLUT is available with<br>
cl-opengl, but a good alternative is lispbuilder-sdl (getting a 3.x+<br>
OpenGL is not yet possible as far as I know with the SDL which<br>
lispbuilder is built upon).<br>
<br>
As for advances in cl-opengl itself, not many in terms of programming<br>
interface, as far as I am aware, though there was updates to allow<br>
access to recent additions to the OpenGL spec, most notably the 3.x<br>
changes.<br>
<br>
If you have any issues getting stuff to work then certainly post them<br>
here on the maillist or maybe drop by the IRC channel #lispgames on<br>
freenode.<br>
<br>
This is the only tutorial resource I am aware of...<br>

&gt; Hi guys, I&#39;m working on a game for the expo competition. Can anyone<br>
&gt; tell me the shortest path to opengl on mac os x? All the posts I&#39;ve<br>
&gt; found are about 2 years old. Have there been any advances on cl-opengl<br>
&gt; since then? I should also mention that I&#39;m completely new to lisp in<br>
&gt; general. This is a trial by fire.<br>
