20140605 12:10:54 <bbbruce> I am running into an issue with AWTTextureIO.newTexture, the resulting texture looks like this https://www.dropbox.com/s/kitfx2ql9wiviz8/Screenshot%202014-06-05%2014.09.57.png
20140605 12:11:44 <bbbruce> when that same BufferedImage is saved to png and loaded through TextureIO.newTexture it all looks fine
20140605 12:13:34 <sgothel> probably GL_UNPACK_ROW_LENGTH or similar (texture width in memory)?
20140605 12:15:33 <sgothel> @xerxes: thx for the heads up
20140605 12:17:18 <sgothel> .. or maybe even 'scanlineStride' is wrongly calculated in impl. ?
20140605 12:17:30 <bbbruce> sgothel: yeah it looks like a stride related problem
20140605 12:18:12 <sgothel> maybe you can debug the code .. and double check .. (then post a patch & test) .. thx!
20140605 12:18:57 <bbbruce> heh, yeah I should get myself comfortable with patching the jogl codebase
20140605 12:19:21 <bbbruce> I seem to run into small fixable things often enough :P
20140605 12:19:50 <sgothel> We use 'AWTGLPixelBuffer' and it's 'AWTGLPixelBufferProvider' (i.e. in Screenshot and GLJPanel) to deal w/ BufferedImage textures ..
20140605 12:20:38 <sgothel> it was planned .. to use those in the old AWTTextureIO impl. .. which currently has low prio (not yet deprecated)
20140605 12:22:13 <bbbruce> I find it a convenient way to load a texture from a BufferedImage. What would replace AWTTextureIO?
20140605 12:22:59 <sgothel> TextureIO + AWTGLPixelBuffer*
20140605 12:23:32 <sgothel> AWTGLPixelBuffer* and GLPixelBuffer* has a more versatile buffer handling ..
20140605 12:23:49 <sgothel> reusage, size check incl. stride .. etc
20140605 12:24:23 <sgothel> the AWT version will even reuse the AWT memory for a new BuffereImage w/ diff. image dimensions
20140605 12:25:18 <sgothel> in the end .. it should be used by AWTTextureIO .. but since 'we' don't use it .. low prio ..
20140605 12:25:29 <sgothel> if you like to jump in .. that would be great
20140605 12:28:13 <xranby> one friend of mine have a debut with the music video "förort" (suburb) http://blogg.svt.se/psl/2014/06/04/premiar-dim-out-forort/ its right of common soul
20140605 12:29:16 <xranby> fresh from sweden
20140605 12:30:49 <xranby> ”CryptoFunkSoulMusic”
20140605 12:34:57 <sgothel> Bow-wow-wow-yippie-yo-yippie-yeah :)
20140605 12:35:33 <bbbruce> something I made for last weekend: http://www.pouet.net/prod.php?which=63528
20140605 12:35:46 <sgothel> ^^ now guess whats that from .. ? -> .. atomic d... :)
20140605 12:35:54 <sgothel> sounds nice .. nice music
20140605 12:37:24 <sgothel> @Bruce: .. err .. thats a different type of .. err 'music' :)
20140605 12:37:56 <sgothel> looks nice .. sound matches .. cool
20140605 12:38:50 <sgothel> kudos .. for the demo Bruce
20140605 12:39:28 <bbbruce> thanks, it is made using jogamp :)
20140605 12:39:53 <sgothel> so .. https://jogamp.org/bugzilla/show_bug.cgi?id=1005 ??
20140605 12:40:34 <sgothel> some demo stuff ?
20140605 12:40:38 <bbbruce> hm, interesting
20140605 12:41:12 <bbbruce> any idea what you'd want to show there?
20140605 12:41:50 <sgothel> https://jogamp.org/bugzilla/show_bug.cgi?id=1005#c7
20140605 12:42:08 <sgothel> last year ( see video / slides ) - we did a big showcase of all stuff done w/ jogamp
20140605 12:42:31 <sgothel> we always has Dominik's great demos .. dunno whether he has something for this year ..
20140605 12:42:56 <bbbruce> he goes by demoscenepacifist no?
20140605 12:42:56 <sgothel> demos would be always great to have while showing things
20140605 12:42:59 <sgothel> yup
20140605 12:44:02 <sgothel> one chapter will be Graph-UI and our progress ..
20140605 12:44:12 <sgothel> rest should be showcasing stuff and discussions
20140605 12:46:15 <bbbruce> yeah he makes good looking stuff, my work is usually more minimalistic :) … so to contribute I'd just give binaries/video + permission? or is open source preferred?
20140605 12:46:57 <sgothel> you know the answer :)
20140605 12:47:22 <sgothel> sure .. and artistic (non commercial) license may be useful here ..
20140605 12:47:36 <sgothel> (for you to exploit your work)
20140605 12:47:54 <sgothel> and still allow folks to learn .. and use
20140605 12:48:18 <sgothel> but however .. we like to show things .. sure
20140605 12:48:23 <sgothel> JOGL + JOAL ?
20140605 12:49:27 <bbbruce> yep
20140605 12:49:38 <bbbruce> and some framework code so that I have to think less :)
20140605 12:49:53 <xranby> does it work on android?
20140605 12:49:55 <sgothel> you are onsite in Vancouver ?
20140605 12:50:06 <sgothel> (i.e. NEWT w/o AWT ?)
20140605 12:50:32 <sgothel> (and core ES2 or ES3)
20140605 12:50:49 <bbbruce> it is built on GL3
20140605 12:51:02 <bbbruce> it should not be too hard to get it to ES2/3
20140605 12:51:05 <sgothel> maybe try GLES3 .. and NEWT .. yup
20140605 12:51:12 <xranby> bbbruce: great exit!
20140605 12:51:17 <bbbruce> and everything is NEWT yes
20140605 12:51:18 <xranby> love it
20140605 12:51:51 <sgothel> if you are onsite .. you could talk a bit about the development if you like
20140605 12:52:09 <bbbruce> sadly I won't be onsite
20140605 12:52:31 <sgothel> then maybe make a page or two .. see prev. slides
20140605 12:54:03 <bbbruce> I am based in .nl, if you happen to be near someday? :)
20140605 12:55:46 <sgothel> nice NL .. great, will ping you .. once a year at least driving through yup (last time was for FOSDEM in Bruxelles)
20140605 12:55:58 <sgothel> we had a stop in Putten :)
20140605 12:57:11 <sgothel> back in a bit .. reboot

20140605 14:30:59 <sgothel> Offthread: ECB: Deposit interest rate now by -0.1 % -> EUR currency no more a storage 'medium' for value :)
20140605 14:34:50 <sgothel> (so now it's loss := -0.1% - inflation_rate )
20140605 14:35:17 <sgothel> maybe the banks will pay you for taking some money :)
20140605 14:38:20 <xranby> "interesting"
20140605 14:38:41 <sgothel> http://www.zerohedge.com/news/2014-06-05/nirp-has-arrived-europe-officially-enters-monetary-twilight-zone .. etc .. etc ..
20140605 14:39:53 <xranby> the old ghost have usually been that politicals say deflation is "bad" that it will end up with people not willing to spend their money
20140605 14:40:04 <sgothel> well, Denmark, Norway, Sweden .. Switzerland .. etc .. are sort of safe for now .. immigration ? :)
20140605 14:40:18 <sgothel> yup
20140605 14:41:07 <sgothel> but debt inflation will not given anybody security to risk any interest rate for new debt, hence (cheap) money wasn't taken out alot in last years
20140605 14:41:23 <sgothel> at least we didn't ..
20140605 14:41:49 <xranby> i did uh oh
20140605 14:42:15 <sgothel> well .. you are safe I guess w/ your business
20140605 14:42:30 <xranby> it looks good yes nothing alarming aproaching
20140605 14:42:48 <sgothel> Scandinavia looks good AFAIK
20140605 14:43:04 <xranby> motala is now an awesome place to bee
20140605 14:43:11 <xranby> we have a 1.5m cosmo gong
20140605 14:43:15 <sgothel> hehe
20140605 14:43:59 <xranby> https://twitter.com/xranby/status/473192313767084032/photo/1 we had a cosmo celebration with 9 gongs playing all night
20140605 14:44:30 <xranby> for the new cosmo gongs inauguration
20140605 14:44:39 <sgothel> sound
20140605 14:44:46 <xranby> much sound
20140605 14:44:52 <sgothel> sound investment :)
20140605 14:47:11 <sgothel> wonder how NIRP works in regards to fractional reserve .. hmm
20140605 14:47:51 <sgothel> gold backed money ? :)
20140605 14:48:16 <monsieur_max> bbbruce: nice demo :)
20140605 14:49:55 <sgothel> on-topic: anybody got a headache regarding https://jogamp.org/bugzilla/show_bug.cgi?id=741 changes ?
20140605 14:50:18 <sgothel> still working on it .. so it might be good if you can verify the API changes ..
20140605 14:51:01 <sgothel> NativeSurface: Using pixel units
20140605 14:51:01 <sgothel> - getWidth() -> getSurfaceWidth() * RENAMED *
20140605 14:51:01 <sgothel> - getHeight() -> getSurfaceHeight() * RENAMED *
20140605 14:51:01 <sgothel> GLDrawable: Using pixel units
20140605 14:51:01 <sgothel> - getWidth() -> getSurfaceWidth() * RENAMED, aligned w/ NativeSurface *
20140605 14:51:02 <sgothel> - getHeight() -> getSurfaceHeight() * RENAMED, aligned w/ NativeSurface *
20140605 14:57:00 <hharrison> sgothel: what kind of verification are you looking for?
20140605 14:57:42 <sgothel> like: (a) do you like it?, (b) does it work for you?, (c) better solution?
20140605 14:58:06 <sgothel> at least - just giving another heads-up here .. triggering adoption :)
20140605 15:00:02 <hharrison> I'm still in camp b)
20140605 15:00:09 <sgothel> :)
20140605 15:00:20 <hharrison> Wish I was in c)
20140605 15:00:33 <hharrison> ;-)
20140605 15:00:38 <sgothel> so you still verify .. yup, me too .. i.e. fixing some bugs
20140605 15:01:13 <sgothel> all graph-ui demos don't work when using the CALayer :(
20140605 15:01:35 <hharrison> interesting....what's the failure mode?
20140605 15:02:01 <sgothel> undefined output .. scrambled or random
20140605 15:02:12 <sgothel> when I reparent to top-level w/o CALayer .. it works
20140605 15:02:26 <sgothel> (i.e. using NewtCanvasAWT)
20140605 15:02:42 <sgothel> other demos work fine .. so some special issue
20140605 15:04:15 <sgothel> graph text w/o employing AA: >= 300 dpi == perfect AA (tablets), ~280 dpi == ok'ish (OSX), ..
20140605 15:06:22 <xranby> sgothel: did you see the new apple anoucements? (object c drivers etc)
20140605 15:07:03 <sgothel> I glanced over the hype of 'new' 'close to the metal' and proprietary APIs .. yes :)
20140605 15:07:12 <sgothel> (AMD, NVidia .. and Apple)
20140605 15:07:37 <sgothel> well, IMHO .. all possible via OpenGL as well, as long you choose the right API entries ..
20140605 15:07:53 <sgothel> (-> GL 4.1 stuff / instanced .. etc etc)
20140605 15:08:20 <xranby> "3 reactions to Metal. AAA engine programmers: Yay!. People using Unity etc: Whatever. People writing cross-platform themselves: WTF?"
20140605 15:08:31 <sgothel> have to finally move perf framework from jogl-demos to jogl, enhance them .. and run it ..
20140605 15:08:49 <xranby> i feel like the WFT camp
20140605 15:08:57 <xranby> WTF
20140605 15:09:14 <xranby> interesting
20140605 15:09:16 <sgothel> Sven: It's a media hype - it's summer - they like to differentiate themselves from competitors ... :)
20140605 15:09:25 <xranby> so we will have a benchmark demo in !
20140605 15:09:30 <sgothel> in short: all bullshit
20140605 15:09:57 <sgothel> yeah .. was based on ES2 stuff (memory transfers and VBO)
20140605 15:10:06 <sgothel> need to pump it up .. w/ new techniques ofc
20140605 15:10:52 <xranby> http://elhigu.github.io/opencl-testsuite/ <- opencl driver testsuite
20140605 15:11:15 <sgothel> https://www.opengl.org/registry/specs/ARB/multi_draw_indirect.txt <- was mentioned explicitly ..
20140605 15:11:44 <sgothel> implying: https://www.opengl.org/registry/specs/ARB/instanced_arrays.txt and https://www.opengl.org/registry/specs/ARB/draw_indirect.txt
20140605 15:11:48 <xranby> only intels drivers passes the tests, hope they will make faster graphics cards
20140605 15:12:28 <bbbruce> I must say that I am quite surprised with the performance of the HD4000 :)
20140605 15:13:25 <sgothel> right .. me also w/ AMDs latest APUs (and open source drivers).. cool stuff
20140605 15:19:15 <monsieur_max> bbbruce: same here, rather powerfull for a gpu that is on most of new laptops
20140605 15:20:38 <sgothel> http://www.zotac.com/en/products/mini-pcs/zbox-nano-series/product/zbox-nano-series/detail/zbox-nano-aq02/sort/starttime/order/DESC/amount/10/section/specifications.html <- AMD HD8510G best price/performance .. for example
20140605 15:20:59 <sgothel> will add one in our jenkins matrix
20140605 15:21:37 <sgothel> afk .. food
20140605 15:31:54 <xranby> sgothel: thank you the NIRP heads up
20140605 15:32:18 <xranby> Europe Gets Negative Interest Rates
20140605 15:32:34 <xranby> what does it mean.. your piggie bank now eats your money
