20160316 07:08:05 <elect_> hi
20160316 07:38:04 * monsieur_max (~maxime@anon) has joined #jogamp
20160316 08:30:35 * Eclesia (~husky@anon) has joined #jogamp
20160316 08:31:22 <Eclesia> good morning
20160316 08:32:50 * jvanek (jvanek@anon) has joined #jogamp
20160316 08:33:20 <monsieur_max> hello
20160316 10:06:36 * spaceemotion (~spaceemot@anon) has joined #jogamp
20160316 12:26:42 <Eclesia> Has anyone played with softbody physics ? used for water, gely ... ? I'm searching for good links about this kind of physics
20160316 12:54:36 <elect_> I am interested
20160316 12:54:56 <elect_> but my idea is to port the new bullet to java using compute shaders
20160316 12:55:19 <elect_> but it's a very long term goal
20160316 12:55:25 <elect_> I didn't really started yet
20160316 12:59:31 <monsieur_max> elect_: what about using sumatra project ?
20160316 13:00:11 <elect_> didnt know about
20160316 13:00:12 <elect_> reading
20160316 13:01:01 <elect_> it doesnt seem really alive
20160316 13:01:26 <elect_> last update 2014-03-04
20160316 13:01:36 <Eclesia> small piece of interesting code : http://illogictree.com/blog/2010/08/navier-stokes-fluid-dynamics/
20160316 13:01:48 <Eclesia> (public domain of course)
20160316 13:03:52 <Eclesia> monsieur_max: you have a link ?
20160316 13:09:26 <monsieur_max> well, tracing back from memories : http://blog.jetbrains.com/idea/2015/10/java-annotated-monthly-october-2015/ you have multiple links regarding this topic
20160316 13:11:20 <Eclesia> k, I was thinking it was somekind of physics engine, that's why I couldn't find anything ^^
20160316 13:14:23 <elect_> anyway, compute shader is better
20160316 13:15:10 <elect_> because you can perform it in several place during the pipeline, it recognizes the glsl structures and has access to the whole opengl infrastructure
20160316 13:15:23 <Eclesia> opengl 4.5 no ?
20160316 13:18:45 <elect_> 4.3
20160316 13:18:55 <elect_> or even 4 with extension
20160316 13:19:29 <elect_> would you be interested, Eclesia ?
20160316 13:19:45 <Eclesia> in a gpu based physic engine ? sure
20160316 13:19:48 <bruce-> hm, I should see if I can use compute shaders in OSX
20160316 13:19:54 <bruce-> (maybe with the nvidia web drivers?)
20160316 13:19:54 <Eclesia> if it's public domain ^^
20160316 13:20:03 <elect_> obviously
20160316 13:20:14 <elect_> there is some sort of interested around
20160316 13:20:44 <elect_> but nobody until now bited it again after the old bullet port we have today
20160316 13:21:05 <elect_> if you think about
20160316 13:21:35 <elect_> it makes a lot more sense since everything is on the GPU, get calculated on the GPU, get used on the GPU
20160316 13:22:45 <elect_> no shits about mixing different APIs
20160316 13:22:49 <elect_> pure OpenGL

20160316 13:24:37 <Eclesia> can we write in a VBO with compute shaders ? I think it was always Textures
20160316 13:24:54 <Eclesia> afterall a vbo is just a 1D texture
20160316 13:24:55 <elect_> yes
20160316 13:25:00 <elect_> you can write everywhere
20160316 13:25:02 <Eclesia> cool
20160316 13:25:19 <elect_> vbo, ibo, images, ssab, ubo
20160316 13:25:45 <Eclesia> ssab ?
20160316 13:26:01 <elect_> you just have to put a fence later regarding what you are going to with the buffer later
20160316 13:26:05 <elect_> sorry, ssbo
20160316 15:31:50 * philjord (599cc172@anon) has joined #jogamp
20160316 16:13:05 <bruce-> meh.
20160316 16:13:17 <bruce-> no compute shaders on osx. even with the nvidia supplied drivers

20160316 16:17:55 <Eclesia> who would pay for a mac anyway
20160316 16:18:01 <bruce-> I would
20160316 16:18:12 <Eclesia> :o
20160316 16:22:32 <elect_> \o/
20160316 16:22:48 <elect_> hw & os, bruce?
20160316 16:23:00 <elect_> If I recall properly, apple has 4.1
20160316 16:23:04 <elect_> + ext
20160316 16:23:10 <bruce-> the hardware is nvidia gtx 780m
20160316 16:23:15 <elect_> nice
20160316 16:23:17 <bruce-> so that should support it
20160316 16:23:31 <elect_> it's a pity then
20160316 16:24:19 <elect_> I guess it's a combo between apple being quite lazy in introducing features, defending the prestige of metal and being sure to not have bugs
20160316 16:48:01 <bruce-> yeah, looks like their bets are on Metal
