[lisp-game-dev] cl-opengl mac os x
Hi guys, I'm working on a game for the expo competition. Can anyone tell me the shortest path to opengl on mac os x? All the posts I've found are about 2 years old. Have there been any advances on cl-opengl since then? I should also mention that I'm completely new to lisp in general. This is a trial by fire. -- Schell Scivally schell@efnx.com (efsubenovex@gmail.com) http://efnx.com http://github.com/efnx
Hi Schell, A lot of people also use some other library to create the window, get the opengl context, do user input etc. Of course GLUT is available with cl-opengl, but a good alternative is lispbuilder-sdl (getting a 3.x+ OpenGL is not yet possible as far as I know with the SDL which lispbuilder is built upon). As for advances in cl-opengl itself, not many in terms of programming interface, as far as I am aware, though there was updates to allow access to recent additions to the OpenGL spec, most notably the 3.x changes. If you have any issues getting stuff to work then certainly post them here on the maillist or maybe drop by the IRC channel #lispgames on freenode. This is the only tutorial resource I am aware of... http://3bb.cc/tutorials/cl-opengl/index.html On Sun, 2010-07-04 at 11:23 -0700, Schell Scivally wrote:

I use lispbuilder-sdl with cl-opengl, and it works pretty well. Thopter ( http://code.google.com/p/blackthorn-engine/wiki/Thopter) was built this way, and runs well on Mac as well as Windows and Linux. I don'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: http://code.google.com/p/lispbuilder/wiki/UsingLispbuilderSDL#Using_OpenGL Hope that helps you get started.

There are chances that cl-opengl works without any modifications, since it only needs OpenGL libraries installed. All you have to do is to clone the repository (http://github.com/3b/cl-opengl) and link the .asd file to ~/.sbcl/systems. Then just require and hack. You might need GLUT though, look at freeglut (http://freeglut.sourceforge.net/). Also, check out glop (http://github.com/patzy/glop), these are new bindings for opengl but you'll need X11. I can't help you more than that since I'm not a OS X user, all I can do is to wish you good luck.
I use cl-OpenGL under MacOSX with sbcl all of the time. I had trouble when I first tried it through SLIME with a threaded version of SBCL. I think it works since I updated my cl-OpenGL install. I'm working on a tutorial for GLSL through cl-opengl. At the moment though, I just have some older GL stuff in cl-opengl on my site: http://nklein.com/ -- Patrick <pat@nklein.com> On Jul 4, 2010, at 1:23 PM, Schell Scivally <efsubenovex@gmail.com> wrote:
