May 5, 2008 [00:00:15] <StephaneLenclud> It's object code so it's a bit all over the place[00:00:57] <StephaneLenclud> When I render only a mesh with one cylinder it works just fine[00:01:31] <StephaneLenclud> when I put one cylinder inside the first one it's broken[00:01:54] <rnx> then make a minimal testcase[00:02:44] <rnx> not sure what the screenshot is supposed to look like[00:02:55] <rnx> but that sure looks like depth issues[00:04:00] <rnx> if you try to draw the two cylinders one after the other sorting obviously won't help[00:04:19] <StephaneLenclud> I'm using glBlendFunc(GL_ONE, GL_ONE);[00:04:43] <StephaneLenclud> and glColor with alpha 0.2[00:04:51] <StephaneLenclud> no material[00:05:00] *** mastro has joined ##OpenGL[00:05:42] <rnx> i recommend you learn a bit about how the depth buffer works and about the issues with alpha and sorting[00:05:59] <rnx> http://www.sjbaker.org/steve/omniv/alpha_sorting.html[00:06:10] *** thesquib has quit

work?[05:31:24] <vasoq> viewer.cpp:(.text+0x26e): undefined reference to `glClear' and many similar things[05:31:32] <HuntsMan> did you do -lGL?[05:31:40] <vasoq> i'm not 100% my makefile is right...

files into the final executable[05:37:57] <vasoq> that fixed gl references but i still have issues with glut and glu... by the way i googled a lot but can't find a clear answer esp regarding makefiles[05:38:34] <HuntsMan> as i said, link also glut and glu[05:38:48] <HuntsMan> and BTW this is not specific to makefiles[05:40:00] <vasoq> i know, i had read something similar[05:40:23] <vasoq> i didn't realize -lGL and -lGLU meant link gl and link glu, but it compiles now :)[05:40:37] <vasoq> just enough to give me a blank screen :([05:41:50] <nathan_> lol[05:44:37] <Madsy> You are using

it's common[05:47:30] <vasoq> common enough that my home university uses opengl and so does this university in germany[05:48:11] <Madsy> Well it's pretty fucked up if they introduce you straight to
