[cl-opengl-devel] Simple texturing help
by Charlie Burrows 29 May '08

29 May '08

I was trying to translate the Nehe openGL example 6 to cl-opengl but I was having some trouble so I cut it down to a single quad with a texture. I'm sure there are many mistakes even in this small example. Could someone take a look at it and give me some pointers. http://paste.lisp.org/display/61397 Thanks, charlieb

[cl-opengl-devel] Two patches...
by Charlie McMackin 04 May '08

04 May '08

The first patch updates the gl.spec and generated bindings. For me, this fixed compile errors with recent ATI/AMD drivers and sbcl 1.0.15 The second patch are my proposed changes to cl-glut. Hopefully it makes for a more friendly save-lisp-and-die functionality for the programmer. It does make one "radical" change however: (glut:init) is no longer called on load. Instead, I made it part of initalize-instance on base-window. Last I made a cosmetic change to base-window, it's my understanding that when you supply :initarg on a slot, it's better to initialize It's value in :default-initargs of the class versus :initform in the slot.... I hope my understanding is sound with that one. Thanks again to _3b on #lisp for his suggestions on the core saving fixes. Any mistakes in the implementation are my own. It works for me though :D Charlie Mac

[cl-opengl-devel] CL-GLUT bug with saving a core
by Charlie McMackin 01 May '08

01 May '08

Dear list, Long time no hear ;) Today I believe I've run into what might be a bug with cl-glut while trying to SAVE-LISP-AND-DIE on sbcl 1.0.15. Running a core saved with cl-glut and my program resulted in freeglut errors like: freeglut ERROR: Function <glutCreateWindow> called without first calling 'glutInit'. _3b on #lisp (Bart B?) though (glut:init) might need to be called on when the core is loaded. When I tried this I got dumped to ldb immediately with illegal pointer errors. I am unsure of the quality of my fix, but I added the following to my :toplevel function and everything worked. (eval-when (:load-toplevel :execute) (setf glut::*argcp* (cffi:null-pointer) glut::*argv* (cffi:null-pointer)) (glut:init)) Saving the core also saves the pointer values of *argcp* and *argv* at the time of saving. If this is The Right Way, I can try writing it up to be put in init.lisp proper... Charlie Mac

[cl-opengl-devel] Patch for 2d mipmap generation and more mouse buttons
by Johann Korndoerfer 07 Mar '08

Hi the attached patch does two things: 1) it adds glu:build-2d-mipmaps 2) as suggested earlier this month, more mouse-buttons are now recognized (:wheel-up, :wheel-down and :button4 to :button7) i'd be happy to see it applied cupe { hunk ./glu/glu.lisp 95 -;;; TODO: gluBuild{1,2,3}DMipmaps; gluBuildP1,2,3}DMipmapLevels +;;; TODO: gluBuild{1,3}DMipmaps; gluBuildP1,3}DMipmapLevels + + +(defcfun ("gluBuild2DMipmaps" %GluBuild2DMipmaps) :void + (target %gl:enum) + (internalformat %gl:int) + (width %gl:sizei) + (height %gl:sizei) + (format %gl:enum) + (type %gl:enum) + (data :pointer)) + + +(defun build-2d-mipmaps (target internal-format width height format type data) + (let ((internal-size (gl::internal-format->int internal-format))) + (if (pointerp data) + (%gluBuild2dMipmaps target internal-size width height format type data) + (cl-opengl::with-pixel-array (array type data) + (%gluBuild2dMipmaps target internal-size width height format type array))))) hunk ./glu/package.lisp 43 + #:build-2d-mipmaps hunk ./glut/callbacks.lisp 183 - :right-button) + :right-button + :wheel-up + :wheel-down + :button4 + :button5 + :button6 + :button7) }

[cl-opengl-devel] GLUT handling for a mouse wheel
by Charlie McMackin 07 Mar '08

07 Mar '08

Having a GLUT window die on me because I accidentally scroll the mouse wheel down finally drove me mad enough to go track the problem down. I'm not sure if this is the correct way to do it, but weighing in at one line sexp it sure feels good. I picked :wheel-down but I guess any keyword can be put in it's place. the change: in glut/callbacks.lisp add (:wheel-down -1) to the mouse-button-state cenum. Charlie Mac

[cl-opengl-devel] division-by-zero error

(argh, forgot to cc the list!) sorry, should have included more details in the first mail. I'm running debian stable, using the closed-source nvidia drivers and built sbcl from source myself. ok well, using (sb-int:with-float-traps-masked (:invalid :divide-by-zero)) as suggested by Luís allows me to load cl-glut-examples, but the issue still occurs if i try to run an example (i.e. rb-hello) backtrace from there is = (SB-VM:SIGFPE-HANDLER #<unavailable argument> #.(SB-SYS:INT-SAP #XB79FB36C) #<unavailable argument>) 0] backtrace 0: (SB-VM:SIGFPE-HANDLER #<unavailable argument> #.(SB-SYS:INT-SAP #XB79FB36C) #<unavailable argument>) 1: (SB-VM:SIGFPE-HANDLER #<unavailable argument> #.(SB-SYS:INT-SAP #XB79FB36C) #<unavailable argument>)[:EXTERNAL] 2: ((FLET #:WITHOUT-INTERRUPTS-BODY-[INVOKE-INTERRUPTION]11)) 3: (SB-SYS:INVOKE-INTERRUPTION #<CLOSURE (FLET SB-UNIX::INTERRUPTION) {B79FB105}>) 4: ((FLET SB-UNIX::RUN-HANDLER) 8 #.(SB-SYS:INT-SAP #XB79FB36C) #.(SB-SYS:INT-SAP #XB79FB3EC)) 5: ("foreign function: call_into_lisp") 6: ("foreign function: funcall3") 7: ("foreign function: interrupt_handle_now") On Thu, Mar 6, 2008 at 2:30 PM, Bart Botta <00003b(a)gmail.com> wrote: > (oops, forgot to reply to the list, sorry about the extra copies) > > > Just as a guess, you might try deleting .fasl files in cl-opengl and > cffi directories, if that doesn't help, will need more information: > > > On 3/5/08, James Baker <cycle.code.media(a)gmail.com> wrote: > > "division-by-zero" issue, I'm using both cffi + cl-opengl from darcs > > and sbcl 1.0.15. > > > What OS/platform/graphics card drivers? > > > > > > (SB-VM:SIGFPE-HANDLER > > #<unavailable argument> > > #.(SB-SYS:INT-SAP #XB79FA9EC) > > #<unavailable argument>) > > 0] > > > > What does it say if you type backtrace at that prompt? > > -- > -b- >
