<nine_milli> isnt that what glgenbuffer creates?[03:02:14] <derhass> you'll also need a VBO if you plan to use vertex arrays[03:02:29] <derhass> but glGenBuffers will be far from sufficient[03:02:36]

<nine_milli> i dont want to stray too far from es2 cuz im just testing until angle is finished[03:04:45] <derhass> why are you using modern GL if you want to match GLES2?[03:04:52] <derhass> GL2.x

you're using 3.2 or 4.1[03:11:55] <derhass> but why on earth do you do that?[03:12:08] <derhass> osx supports GL2.1[03:12:13] <nine_milli> thats the lowest one i saw[03:12:15] <btipling> it supports up to 4.1[03:12:26] <derhass> btipling: but not in compat profile[03:12:31] <btipling> right[03:12:35] <derhass> and compat/legacy is what nine_milli needs[03:12:41] <btipling> ohh[03:12:45]

Widgets draw themselves only when changes are made to them. Ultimately they're just textures being drawn, but they're procedurally drawn at an earlier time.[03:52:01] <Xeek> Stragus: my concept is probably the same as yours. I'm not generating these widgets rectrangle by rectangle every frame.[03:52:21] <Stragus> Ah good, so they are stored as textures after all[03:52:50] <Xeek> yeah, they dont reconstruct until something like resizing happens, which most widgets can't do in a game ui anyway.[03:53:16] <Xeek> I've alrady written a UI that works this way, was very pleaed with it except that it used the SDL renderer instead of raw GL[03:53:27] <Stragus> You shouldn't need to re-generate the graphics, unless the corner size changes[03:54:13] <Xeek> Stragus: thats if I'm less flexible and confine the rendering of widgets based on regions (like corners and edges). I'm just not willing to do that[03:54:57] <Xeek> Stragus: unless I do something like have multiple textures for each widget[03:55:19] <Stragus> That consumes a lot more texture bandwidth, and a lot more memory if you end up having 200 text fields of different sizes[03:55:48] <Xeek> really though. I'm not expecting a lot of change. it should be fine[03:56:09] <Xeek> the worst widget for changes occurring would be something like a label[03:57:45] <Xeek> edit control updates and redraws 2 rectangles and text ... I dont think the framerate is even going to feel it.[03:58:19] <Stragus> Eheh, all right.
