[cl-opengl-devel] playing with opengl at the repl
by Jose A. Ortega Ruiz 13 Jul '08

13 Jul '08

Hi, I'm currently learning OpenGL, using to that end cl-opengl. It comes without saying that one of the main advantages of using Lisp here is the ability to experiment interactively at the REPL. The examples i've seen so far, though, use a blocking call to GLUT:DISPLAY-WINDOW to run (which is OK for such examples, i don't complain), and i was wondering about what would be the best way to have an OpenGL/GLUT window open and manipulate it from a (non-blocked) REPL, maybe even while the GLUT main loop is running. Threads come to mind (i'm using SBCL on Linux), but probably more experienced readers of this list will have some other (or more concrete) advice/code snippets/configurations/whatever to share? Needless to say, pointers to documentation or examples in any form would also be very welcome. Thanks a lot for your time! Cheers, jao -- Always have a vision.

[cl-opengl-devel] [patch] game mode and init-window position/size
by Dan Torop 06 Jul '08

06 Jul '08

Attached is a patch which enables game mode via a window initarg "game-mode". The enter-game-mode and leave-game-mode calls must be used instead of create-window and destroy-window, hence the somewhat invasive coding. I'm not sure if this is the right approach, another possibility would be to make a sibling class of "window", "game-mode-window"? I also made the display-window :around method for windows set init-window position and size, so that the window isn't created one place then immediately modifed. But the base-window's display-window :around still calls position/reshape window. Apologies, this is sloppy, but I didn't want to muck with part of the code with which I wasn't at all familiar. Hope any of this is of use in some form? Thank you, Dan

[cl-opengl-devel] [patch] fog-color, texture-border-color, gluPerspective
by Dan Torop 06 Jul '08

06 Jul '08

Hello! Appended are a few very minor patches: gl/rasterization.lisp: - in gl:tex-parameter's :texture-border-color use "elt" rather than "aref", to be consistent with other calls in the file - in gl:fog allow :fog-color -- I hope this is done in a manner consistent with cl-opengl style? glu/glu.lisp: - change names of some gluPerspective parameters to match their standard names Thanks for the very useful cl-opengl code! I hope these are worth applying! Best, Dan

[cl-opengl-devel] push-attrib / pop-attrib
by Bastian Müller 06 Jul '08

06 Jul '08

Hej cl-opengl developers, I'm trying to use push-attrib, but unfortunately it doesn't work. (gl:push-attrib :current-bit) -+ Errors (1) `-- (in macroexpansion of (CL-OPENGL:PUSH-ATTRIB :CURRENT-BIT)) (hint: For more precise location, try *BREAK-ON-SIGNALS*.) Unknown CFFI type: CL-OPENGL::SERVER-ATTRIBUTES. ;; external (defun push-attrib (&rest attributes) (declare (dynamic-extent attributes)) (%gl:push-attrib (make-bitfield 'server-attributes attributes))) (define-compiler-macro push-attrib (&whole form &rest attributes) (if (every #'keywordp attributes) `(%gl:push-attrib ,(make-bitfield 'server-attributes attributes)) form)) There's no enum called server-attributes anywhere in the current HEAD. Another problem is that pop-attrib is exported, but is never defined (only the defcfun function (%pop-attrib), no high-level/wrapper method). Any hints? Thanks. kind regards, Bastian
