20160307 09:19:10 <elect> how can I have multiple glContext in jogl?
20160307 09:19:30 <elect> if I am using newt, can I have a glWindow with multiple contexts?
20160307 09:39:03 <bruce-> you can make contexts without window
20160307 09:55:15 <elect> and then?
20160307 09:55:26 <elect> I just bind the windows to the context I want?
20160307 09:58:37 <bruce-> I am not sure what you want to do with multiple contexts. I have only used shared contexts to do off thread loading of textures
20160307 09:59:45 <elect> what's exactly a shared context?
20160307 09:59:54 <elect> a context being used by multiple threads?
20160307 10:00:09 <elect> what's the point if only one context can be active a time?

20160307 10:28:38 <Eclesia> hi
20160307 10:30:42 <elect> hi
20160307 10:32:01 <monsieur_max> hi
20160307 10:44:03 <rmk0> elect: a shared context is a context where objects created on it become visible on another context as well
20160307 10:45:16 <rmk0> so you can create and populate a texture on a separate context (and thread), and then use it on the main context when it's loaded
20160307 10:45:54 <elect> can you render while another thread from another context is loading texture?
20160307 10:46:08 <elect> I thought only one context at time
20160307 10:46:19 <rmk0> one context per thread
20160307 10:46:49 <rmk0> it's debatable whether it will actually improve performance... i've heard that a lot of GPUs can't render and copy at the same time
20160307 10:47:01 <rmk0> it's unlikely to be worse, though
20160307 10:48:26 <elect> ok
20160307 10:48:58 <elect> and is it possible to have multiple profiles?
20160307 10:49:23 <elect> one gl3 compatibility and one gl3 core for example
20160307 10:49:28 <elect> in the same app
20160307 10:49:35 <rmk0> yeah, scarily
20160307 10:50:05 <elect> what you mean? Fragile?
20160307 10:50:41 <rmk0> i don't think anyone knows what happens when you create an object that's supported in one context and not the other, and try to share them
20160307 10:50:51 <rmk0> undefined behaviour, almost certainly
20160307 10:54:08 <bruce-> https://lh3.googleusercontent.com/-lMQHY_jkB2w/Vmy6OzVdCFI/AAAAAAAAmuk/M3RUDlbyCH0/w800-h800/tumblr_mkowtanmh91s8o1r4o1_500.gif
20160307 10:54:48 <rmk0> possibly!

20160307 21:09:27 <gouessej> hi
20160307 21:09:59 <gouessej> Who has a Reddit account here?
20160307 21:10:47 <monsieur_max> i have, but not using it
20160307 21:18:16 <dwbrite> I do. What's up? And I'm wondering about a glitch. I'm super new to OpenGL/JOGL and I have a window up using NEWT but when I mouse over to resize there's no resize arrow.
20160307 21:19:23 <monsieur_max> dwbrite: which OS ?
20160307 21:20:31 <dwbrite> Windows 10. The program is basically elect86's JOGL 3 "Hello Triangle" sample.
20160307 21:21:19 <dwbrite> GL3* I guess.
20160307 21:22:09 <gouessej> dwbrite: setResizable(true)?
20160307 21:22:56 <dwbrite> No dice.
20160307 21:25:08 <gouessej> dwbrite: elect is often here, I advise you to contact him tomorrow
20160307 21:26:12 <dwbrite> Alright, thank you for your time.
20160307 21:26:17 <gouessej> dwbrite: Mayve there is a bug in NEWT. Windows 10 doesn't handle the resizing like Windows 8
20160307 21:26:35 <gouessej> dwbrite: I remember that there is a subtle difference
20160307 21:27:42 <gouessej> dwbrite: the resize cursor appears when you leave the component
20160307 21:28:29 <dwbrite> When I leave the component?
20160307 21:30:00 <gouessej> dwbrite: I'll check that tomorrow as I don't have Windows 10 at home (I'm not a big fan of Microsoft products...)
20160307 21:35:30 <dwbrite> Yeah I've been feeling a bit burnt by MS recently. It's just too much of a hassle to swap OSs on my two machines.
