20160317 12:16:22 <Eclesia> So after all the talking on a physics engine on gpu, who is really motivated AND have some time for it ?
20160317 12:46:43 <elect> first part I am ok
20160317 12:46:55 <elect> second is kind of unavailable
20160317 12:48:53 <elect> but if this takes off I can offer at work to spend resources on that
20160317 12:49:01 <elect> = me
20160317 12:49:04 <elect> :s
20160317 12:49:34 <elect> this is the entry point https://github.com/bulletphysics/bullet3/blob/master/docs/GPU_rigidbody_using_OpenCL.pdf
20160317 12:51:11 * monsieur_max (~maxime@anon) has joined #jogamp
20160317 12:51:45 <elect> cool thing about compute
20160317 12:51:57 <elect> we complete skip all the shits about having another api
20160317 12:52:18 <elect> opencl context initialization, target devide, compiling, etcc
20160317 12:52:34 <Eclesia> I agree, let's forget opencl
20160317 12:54:12 <dwbrite> Good morning
20160317 12:54:19 <elect> hi
20160317 12:54:26 <dwbrite> I passed all my tests :)
20160317 12:54:38 <elect> did you have any doubts ^^
20160317 12:55:30 <dwbrite> I actually did have my doubts, but it turned out I was ready. I aced every single one!
20160317 12:55:36 <Eclesia> I have a bunch of code for physics, geometry computation, integrator, .... but with some bugs ^^
20160317 12:55:50 <elect> where do they come from?
20160317 12:56:15 <Eclesia> that's a question for who ?
20160317 12:56:32 <elect> you :p
20160317 12:57:03 <elect> have you already some experience?
20160317 12:57:24 <Eclesia> depends, I found a 2D physics engine called Traer in public domain, and everything I've read tutorials and buyed books
20160317 12:57:38 <Eclesia> but as I said : it doesn't work well
20160317 12:57:41 <elect> I guess most of the concepts are transportable
20160317 12:58:17 <Eclesia> if we can't make it work on cpu, no chance we are going to make it on gpu
20160317 12:58:43 <elect> I kind of share your point of view
20160317 12:58:57 <Eclesia> gpu is just to speed up thing so the engine has to do things right first
20160317 12:59:07 <elect> but take in account they re-wrote bullet3 from zero because the cpu version obviously didn't scale well on gpu
20160317 12:59:20 <Eclesia> sure
20160317 12:59:35 <elect> what we can do
20160317 12:59:41 <elect> is replying the gpu version on cpu
20160317 12:59:52 <elect> for debugging
20160317 13:00:12 <elect> althought we have some level of debug on the gpu
20160317 15:46:50 <zubzub> Eclesia: are you going to make a fluid shader?
20160317 15:46:56 <zubzub> are you going to solve the age old problem
20160317 15:47:10 <zubzub> of fluid collision with a fixed shore/river bank in games
20160317 15:47:26 <zubzub> where now it's just a straight line
20160317 15:48:06 <zubzub> (it has bothered me ever since quake 1)
20160317 15:48:17 <zubzub> (and still not a single game has properly fixed it)
20160317 15:48:54 <zubzub> sure we have character heads with thousand of hairs
20160317 15:49:00 <zubzub> but a river shore
20160317 15:49:05 <zubzub> that's just an intersection of 2 surfaces
20160317 15:49:37 <Eclesia> zubzub: of course, I can solve everything and send you a beer for free ;)
20160317 15:49:51 <zubzub> if you solve it, I'll send you a beer
20160317 15:49:54 <zubzub> how about that :p
20160317 15:50:12 <Eclesia> I don't like beer
20160317 15:50:27 <zubzub> that's because you never tasted belgian beer
20160317 16:32:26 <monsieur_max> zubzub: send the beer, i live close to Eclesia and i love beer, especially belgian ones :)

20160317 16:38:34 <Eclesia> monsieur_max: cool, so you do the easy task of fluid physics and shorelines ;)
20160317 16:39:17 <monsieur_max> Eclesia: i'll do the task of consuming the fluid sent by zubzub
20160317 16:40:47 <monsieur_max> Eclesia: but well, would love to help you, but i got really too much work ... will probably port my game engine to monogame, which means a lot of work
20160317 16:50:30 * monsieur_max (~maxime@anon) Quit (Quit: Leaving.)
20160317 17:04:05 <Eclesia> end of day, going home. I will try to convert the clothe (in 2d physic) to 3d this evening.
