20160218 12:33:10 <gouessej> Hi
20160218 12:33:29 <gouessej> The trusted certificates expired a few days ago
20160218 12:33:45 <gouessej> Someone must renew the certificate and sign all JARs anew
20160218 12:34:11 <gouessej> xranby: Who can do it? Sven is busy
20160218 12:39:00 <gouessej> rmk0: Is it something that you can do?
20160218 12:40:35 <xranby> gouessej: hi! afaik only sven can sign using sven's certificate
20160218 12:41:45 <gouessej> xranby: yes he has the private key required to generate the P12 key store and then the JKS key store
20160218 12:42:11 <gouessej> xranby: I contacted him but I assume that he's very busy nowadays
20160218 12:43:24 * philjord (599cc172@anon) has joined #jogamp
20160218 12:51:34 <gouessej> xranby: This is the kind of trouble it causes: http://forum.jogamp.org/code-signing-cert-expired-td4036295.html
20160218 12:52:11 <xranby> i have seen it.. 2.3.2 is stillsigned with the new certificate
20160218 12:52:15 <xranby> as i understood it
20160218 12:54:34 <xranby> the only workaround we can offer at the moment is to use the security exception mechanism
20160218 12:54:36 <xranby> https://www.java.com/en/download/faq/exception_sitelist.xml
20160218 12:55:51 <xranby> if the user wants to use the old release
20160218 12:56:16 <xranby> the user also have the option to sign the release themself
20160218 12:57:42 <xranby> i think this only relates to oracles closed source javaws
20160218 12:58:21 <xranby> afaik icedtea-web would ask the user if the user would like to run while warning that the certificate have expired
20160218 13:04:24 <gouessej> The new certificate seems to be expired too

20160218 13:11:25 * Eclesia *clap clap clap*
20160218 13:12:22 <rmk0> john chapman gets all the credit, is his variant of the algorithm
20160218 13:12:37 <rmk0> he didn't use a bilateral filter though
20160218 13:12:52 <elect> bravo
20160218 13:12:57 <rmk0> http://waste.io7m.com/2016/02/18/ssao_0.png
20160218 13:13:04 <rmk0> don't know about you... but i kind of like the noisy version
20160218 13:13:27 <bruce-> I also like the noisy version
20160218 13:13:54 <rmk0> the blur pass is separate and optional, obviously
20160218 13:13:57 <bruce-> but the noise does not really work well you start shading the surface
20160218 13:14:31 <rmk0> will take a picture of the fully shaded version with noise
20160218 13:14:46 <bruce-> http://fileunderpopular.com/preview/facade-4.mp4
20160218 13:14:54 <bruce-> hm, that is more than a year ago that I worked on that
20160218 13:15:06 <bruce-> really want to get into 3d rendering again
20160218 13:16:04 <rmk0> nice
20160218 13:16:27 <Eclesia> 4 devs here => 4 engines. we aren't efficient ^^
20160218 13:16:57 <bruce-> but mine has a funny name!
20160218 13:17:47 <rmk0> and i'm infuriating to work with!
20160218 13:18:57 <Eclesia> and i won't tolerate anything beside rewriting from scratch in public domain
20160218 13:19:27 <xranby> and i only care about blood analyzers running on cheap system on a chip solutions
20160218 13:19:41 <rmk0> http://waste.io7m.com/2016/02/18/unfiltered.png
20160218 13:19:48 <rmk0> that's half-resolution SSAO without filtering
20160218 13:19:51 <bruce-> wow, just imagine our powers combined
20160218 13:19:56 <rmk0> gets a bit rough in the distance due to aliasing
20160218 13:20:42 <xranby> we have one hidden developer gohai who work in the twilight zone to make jogamp deployments work on embedded devices
20160218 13:21:03 <xranby> testing jogamp on free software driver implementations
20160218 13:21:37 <xranby> gohai's interest is to have processing 3 running on all embedded arm soc's for use in art
20160218 13:21:48 <bruce-> interesting
20160218 13:22:46 <bruce-> I am currently writing documentation for my "creative coding" library
20160218 13:23:13 <xranby> gohai makes great progress collaboarting with the mesa3d and raspberry pi foundation at the moment to resolve the driver messup on the raspbian distribution https://jogamp.org/bugzilla/show_bug.cgi?id=1290
20160218 13:23:27 <bruce-> it is sort of supposed to fill the gap between processing sketches and building something a bit larger
20160218 13:24:18 <elect> really nice bruce
20160218 13:24:50 <elect> what was that?
20160218 13:28:40 <bruce-> elect: that video is from a simple 3d engine I wrote on top of said creative coding library. It exposes shaders PBR style materials, uses ssao and variance shadow maps
20160218 13:29:40 <bruce-> oh and it uses freemarker to generate shaders based on active lights and user defined shading
20160218 13:30:56 <elect> what's the main difference between standard materials (diffuse, ambient, specular, shininess, emission) and pbr?
20160218 13:31:04 <elect> just more realism?
20160218 13:31:25 <bruce-> it expresses the materials in terms that actually exist in the real world
20160218 13:31:41 <elect> and by a computational point of view?
20160218 13:31:53 <elect> heavier/lighter?
20160218 13:32:06 <bruce-> depends on the chosen approximations
