[cl-opengl-devel] texture coord array
by Dmitri Hrapof 19 Dec '07

19 Dec '07

Hello! On SBCL 1.0.9 (if it matters) I had to slightly edit EMIT-GL-ARRAY-BIND-CLAUSE, writing "%gl:tex-coord-pointer" instead of just "tex-coord-pointer", otherwise it complained at run-time that "CL-OPENGL::TEX-COORD-POINTER" was undefined. By the way, what's planned for quadrics and nurbs? CLOS classes with finalizers? Sincerely yours, Dmitri

[cl-opengl-devel] disable glut main loop
by Deepankar Sharma 19 Dec '07

19 Dec '07

I am writing a simple game using cl-opengl (a pacman clone) and would like to have my game event loop call the rendering loop. I know freeglut enables a notion like this with glutMainLoopEvent. Is there any way to do the equivalent in cl-opengl ? I did run across the special variable *run-main-loop-after-display* - but it doesnt seem to take any effect. setting this variable to nil still causes the quad in render-to-texture to rotate - am i missing something ?

Hello Mikael, Thanks for the pointers. I will try installing cffi and cl-opengl both from darcs. Is there any reason why the darcs version isnt moved into the official cl-opengl darcs repository ?

[cl-opengl-devel] Problem building cl-opengl
by Deepankar Sharma 16 Dec '07

16 Dec '07

I was recently trying to build cl-opengl on sbcl 1.0.12 / ubuntu amd64. I am using the trunk version of cffi - and some errors pop up while installing cl-opengl. 1) In the file gl/types.lisp - the translate-p keywords for defctype do not seem to be supported anymore in cffi. 2) In the file funcs.lisp cffi::lisp-function-name is used. This is not an available function anymore. Can you please fix this. Another related question is - should i be using the cffi 0.9.2 available on the cffi website ? Regards, Deepankar

[cl-opengl-devel] textures
by Tudor Achim 08 Sep '07

08 Sep '07

Hi, I'm following nehe's tutorials at nehe.gamedev.net, and I'm having a lot of trouble with loading and binding textures. So, I *tried* to approximate what happened in his tutorial: I opened a stream to the bmp file with (setf test (open "/home/tudor/email.bmp" :element-type '(cl-user::unsigned-byte 8))) Then, I made an 1d array of 5000 elements (just so it was 'big enough') and stored the rgb values in it with (read-sequence test-array test) However, when I do (gl:bind-texture gl:tex-image-2d test-array), it says that cl-opengl:tex-image-2d is unbound. What am I doing wrong? Thanks, Tudor

[cl-opengl-devel] Installing cl-opengl
by Gatewood, Walter P. CIV NAVAIR 24 Jul '07

24 Jul '07

I have been through the Practical Common Lisp book online and have selected SBCL to use under SLIME on my Fedora Core 6-64 installation. I have found hints here and there concerning the installation of cl-opengl and I actually guessed the magic incantation once but due to a flash of stupidity I blew away the .sbcl directory. Are there are step-by-step instructions somewhere on the web that would be helpful in getting it to work again? Thanks.

[cl-opengl-devel] Approach taken by cl-opengl for binding creation
by Brad Beveridge 28 Jun '07

28 Jun '07

Hi guys. I really like the cl-opengl bindings, well done! Would somebody care to give a few lines describing how they were made & the underlying philosophy? From reading the code it looks totally hand tailored, apart from the automatic enum generation. Is this an accurate statement? Are the bindings so nice simply because a lot of care was taken? I plan to create bindings for nVidia's Cg API, which I'll post here at some stage in the future. Cheers Brad

[cl-opengl-devel] How are functions ordered?
by Brad Beveridge 25 Jun '07

25 Jun '07

I would like to add some functions to cl-opengl, but I figure that if I am going to send a patch in it might as well be in the style of the current code. It looks like functions are have been added in the order they appear in a book or something? I have probably missed something obvious, but which book do the chapters refer to? Cheers, Brad
