lol[11:26:59] <Yaniel> no problem[11:27:15] <Yaniel> just remember that the answer may take time too :P[11:27:41] <Yaniel> anyway, a good start would be describing what you are trying to do in genereal[11:29:23] <Dariusz> ok got it(I think) so I'm trying to understand the GL in order to load a 2 separate openGL applications under 1 program. Imagin max/maya/blender/etc when you open the program you have viewport/viewports that are all showing thesame data. What I want is to have 2 viewports showing different unrelated to each other data. Normally in my head I have classSomething, if I do classSomething a, classSomething b, I have 2[11:29:23] <Dariusz> instances of that class - ie 2 sets of data. But with openGL all I do is glGenBuffers()/bindBuffers/BufferData, but I never specify which GL "engine"? I'm a bit lost...[11:30:34] <Stragus> glViewport(), draw stuff there. glViewport(), draw other stuff there.[11:30:38] <Dariusz> or is it glGebUffers(1) ? I can have glGenBuffer(1,dataA) glGenBuffer(2,dataB), that makes 2 different "partitions"? in engine and then when I use paingGL() I specify which partition to paint?[11:30:58] <Stragus> Buffers store data, it's totally unrelated to viewports[11:30:59] <Dariusz> glViewport(0,0,width,height) I don't specify source there do I ?[11:31:12] <Stragus> You draw whatever you want in each viewport[11:31:18] <Yaniel> what do you mean by viewport now[11:31:23] <Dariusz> humh[11:31:25] <Yaniel> a subrectangle of your GL window[11:31:31] <Yaniel> or a completely separate window[11:31:39] <Yaniel> (within the same app)[11:31:52] <Dariusz> ok so say I have glGenBuffers(1,dataA) glGenBuffer(2,dataB), how can I now display 2 glwindow with each showing different dataA/B ?[11:32:11] <Stragus> Buffers store data, it's totally unrelated to viewports[11:32:13] <Yaniel> no[11:32:35] <zid> Sounds like an 'ask your operating system documentation' problem[11:32:39] <Dariusz> or w QOpenGlwidget[11:33:13] <Dariusz> the problem I have is that I never create openGL object[11:33:33] <Yaniel> I think you are just misunderstanding the entire OpenGL architecture[11:33:33] <Stragus> I think you should learn OpenGL and it will make a lot more sense...[11:33:36] <Dariusz> or else I would do openGL engineA, openGL engine2. engineA.loadMesh() / engineB.loadMesh()[11:35:30] <Dariusz> I'm lost[11:35:43] <Dariusz> how do you specify in viewport which data it should display ?[11:36:02] <Stragus> glViewport(), glDraw*(), glViewport(), glDraw*()[11:36:04] <Yaniel> you are probably confusing a few components here[11:36:28] <Yaniel> you have a QOpenGlWidget, which has a GL *context*[11:36:35] <Dariusz> as far as I know to display triangle, I need to send data to gpu "buffers" and then use paintGL to display it[11:36:52] <Yaniel> the context is thread-local so when you activate it all gl commands happen on it[11:37:11] <Yaniel> this is basically the same as a separate gl window[11:37:21] <Dariusz> humh[11:37:40] <Yaniel> within the context you can tell gl to only render on a part of the framebuffer (view area)[11:37:41] <Dariusz> I'm not sure if I use QT Gl implementation tho[11:37:53] <Yaniel> that is what glViewport does[11:37:59] <zid> I'm assuming the answer on windows would just be to call wglMakeCurrent twice per frame[11:37:59] <Dariusz> oh[11:38:05] <Yaniel> so if you want to draw say, a minimap[11:38:11] <Yaniel> then you could use this[11:39:13] *** ratchetfreak <ratchetfreak!~ratchetfr@ptr-82s3g7n8nco8egy36si.18120a2.ip6.access.telenet.be> has joined ##OpenGL[11:39:50] <Dariusz> so you are saying if I call a glGenBuffers() in my class, then that sets the data for that class only, and when I call it in other class it sets the data in other class and there is no cross "share" between the 2 classes despite me not creating 2x gl engines?[11:40:12] <Stragus> Your classes have absolutely nothing to do with GL resources[11:40:29] <Stragus> If you create a buffer in a GL context, it doesn't care from which class/whatever you use it[11:40:47] <Dariusz> yep[11:41:11] <Dariusz> so if I do glDrawArrays(GL_TRIANGLES,0,3), this will draw all that gl has in its buffers?[11:41:12] <Yaniel> to make things more confusing, you opengl contexts can share resources[11:41:47] <Yaniel> that will draw one triangle with whatever buffers are currently bound in the current context[11:41:56] <Dariusz> hmmm[11:42:29] <Stragus> You really should learn OpenGL before trying to plan you code[11:42:33] <Stragus> your* code[11:43:04] <Dariusz> is this not what I'm doing now?[11:44:02] <Stragus> There are good resources to learn OpenGL in the channel's topic[11:44:03] *** Murii <Murii!~Murii@79.113.205.114> has quit IRC (Quit: WeeChat 1.4)[11:44:21] *** Murii <Murii!~Murii@79.113.205.114> has joined ##OpenGL[11:45:30] <Dariusz> well I was following this serries https://www.youtube.com/watch?v=Dyue3MzJDss&list=PLRwVmtr-pp06qT6ckboaOhnm9FxmzHpbY&index=5 (total 300 vids if u add game math stuff) but he never touched down on the buffer/qt/etc[11:45:46] <Dariusz> so I dunno, its why I'm asking here to fill in the blanks that he left[11:45:56] *** YungMoonHodler <YungMoonHodler!~me@unaffiliated/boscop> has quit IRC (Ping timeout: 256 seconds)[11:46:17] *** ratchetfreak <ratchetfreak!~ratchetfr@ptr-82s3g7n8nco8egy36si.18120a2.ip6.access.telenet.be> has quit IRC (Read error: Connection reset by peer)[11:46:32] *** YungMoonHodler <YungMoonHodler!~me@2a02:810c:c7c0:1965:dcfb:9e3:d33e:207b> has joined ##OpenGL[11:46:32] *** YungMoonHodler <YungMoonHodler!~me@2a02:810c:c7c0:1965:dcfb:9e3:d33e:207b> has quit IRC (Changing host)[11:46:32] *** YungMoonHodler <YungMoonHodler!~me@unaffiliated/boscop> has joined ##OpenGL[11:46:45] *** ratchetfreak <ratchetfreak!~ratchetfr@ptr-82s3g7n8nco8egy36si.18120a2.ip6.access.telenet.be> has joined ##OpenGL[11:47:12] <Dariusz> ok solved, Qt window handles creation of context and then all is bind to that window/class.
