20141118 09:10:44 <gouessej> Hi
20141118 09:10:58 <gouessej> xranby: Good change :) You're right
20141118 09:11:10 <gouessej> xranby1: Good change :) You're right
20141118 09:12:22 <gouessej> zzuegg2: You probably do something wrong with your buffer, It happens when there is an attempt of reading beyond the "end" of a direct NIO buffer

20141118 10:52:37 <zzuegg2> gouessej: i see, the only thing is it happens randomly. but i will investigate
20141118 11:31:14 <eclesia> pfff, why does nearly all 3d format use different coordinate systems..

20141118 14:32:37 <rmk0> i'm calling glReadPixels on a GL returned by a swing GLCanvas
20141118 14:32:51 <rmk0> it prints "function is no-op" to standard error and otherwise does nothing... why is this?
20141118 14:42:19 <rmk0> .. i can't even see the string "function is no-op" in the jogl codebase
20141118 14:51:42 <rmk0> alternately, is there a good way to dump the contents of a GLCanvas to a PNG file, if glReadPixels isn't going to work?
20141118 14:55:55 <zubzub> you could do it on display server level
20141118 14:56:15 <zubzub> if you're on X and you can get a hold on the window handle
20141118 14:56:25 <rmk0> no, it's got to be platform independent
20141118 14:57:09 <rmk0> i've no idea why glReadPixels is suddenly "broken"
20141118 14:57:24 <rmk0> i can't even work out what's causing the "no-op" message to be printed
20141118 14:57:25 <zubzub> isnt glreadpixels ancient?
20141118 14:57:47 <rmk0> it's still in the latest opengl
20141118 14:57:51 <zubzub> maybe it needs some more ancient boilerplate setup for it to work(?)
20141118 14:58:02 <zubzub> glbegin stuff or something
20141118 14:58:03 <zubzub> dunno
20141118 14:58:08 <rmk0> nope
20141118 14:59:15 <rmk0> it looks like the message comes from mesa
20141118 15:02:32 <rmk0> what the hell...
20141118 15:02:52 <rmk0> it's apparently all OpenGL function calls
20141118 15:17:29 <rmk0> .. suspect this is a threading issue
20141118 15:24:59 <rmk0> yes, it was]
20141118 15:29:52 <rmk0> if you make any OpenGL calls from the wrong thread, mesa will give you that useless error
