linux[09:41:19] <immibis> last time I looked at android opengl, you had to initialize it in java. that was when 2.3 was new[09:44:10] <macroprep> so all 3 platforms would STILL require openGL to actually be initialized for the current process right?[09:46:08] <immibis> yes?[09:46:13] <immibis> otherwise how does it know where you want to draw?[09:47:26] <macroprep> cus SurfaceFligner or

how to seperate the initialization code from the rendering code https://github.com/tsaarni/android-native-egl-example/blob/master/src/main/jni/renderer.cpp[09:51:28] <Yaniel> and more tedious than difficult[09:51:52] <immibis> why don't you know that?[09:52:03] <macroprep> and as far as i know this si the only example that DOES NOT initialize it using java[09:52:07] *** snyp

the differences between EGL and GLX and WGL?[09:54:15] <macroprep> eg glClearColor, glShadeModel and all the rest would be part of setting up the renderer as apposed to the context, window, and stuff

joined ##OpenGL[09:57:30] <macroprep> wish there where wrappers that would handle all this for me in a few lines like in the cube's main() `glutInit(&argc, argv); glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH); glutCreateWindow("red 3D lighted cube"); glutDisplayFunc(display);`[09:57:52] <Yaniel> that code does exactly that[09:58:32] <Yaniel> it just also sets some global GL state in the init function[09:58:57] <Yaniel> which is not exactly wrong, but in anything bigger than a hello cube you should not trust global state to be what you expect when rendering[09:59:39] <immibis> macroprep: sounds like GLSurfaceView[10:03:40] <macroprep> so how would i get it to display two windows/surfaces/whatever, in 2 threads[10:05:17] <macroprep> would i just do pthread_create(&_threadId, 0, threadStartCallback, this); but provide width and height for each? or would it be more complex than that[10:06:06] <macroprep> cus it uses global variables[10:08:14] *** snyp <snyp!~Snyp@202.83.17.8> has quit IRC (Ping timeout: 244 seconds)[10:09:07] <immibis> you would create a window/surface/whatever and create another window/surface/whatever[10:09:21] <immibis> it's not opengl's problem how you do that[10:09:36] <immibis> make sure to set the context correctly in each thread[10:10:16] <macroprep> but i want to use a single window[10:10:54] <macroprep> so i dont have

be fully replaced?[10:43:53] <Yaniel> since VBOs were introduced[10:44:34] <Yaniel> so technically GL1.1[10:44:44] <Yaniel> which introduced EXT_vertex_array[10:44:52] <Yaniel> (clientside arrays)[10:45:04] <mkoncek> wikipedia states 1.4 as ARB and 2.1 as a part of GL[10:45:24] <Yaniel> 1.5 added ARB_vertex_buffer_object for GPU-side buffers[10:46:13] <mkoncek> "The vertex buffer object
