If you use non-standard libraries, you should at least tell us which libraries you use.[00:07:50] <Madsy> Most of us are glad to help, but not if it means doing a lot of work which you should have done beforehand.[00:07:53] *** vade has quit IRC[00:08:26] <shuffle2> http://cpp.ninjacodemonkeys.org/5067 http://cpp.ninjacodemonkeys.org/5066 http://cpp.ninjacodemonkeys.org/5065[00:08:32] <shuffle2> you cant compile it probably[00:08:41] <shuffle2> it has too many deps as you can see from glwindow.h[00:08:51] <Madsy> *shrug*[00:09:03] <shuffle2> lolz this is why i hate ogl[00:09:27] <Madsy> Problem solving and proper etiquette has little to do with OpenGL.[00:09:42] <shuffle2> probably all you need to look at is the registerwindowclass and the ctor[00:09:49] <shuffle2> because the problem occurs there already[00:10:40] <Madsy> You could start off by telling us what the problem is. What do you want to happen? What happens instead? What does GetError and glGetError return?[00:11:01] <shuffle2> it's probably to do with registerwindowclass, i'm thinking[00:11:03] <Madsy> Err.. GetLastError, sorry[00:11:07] <Madsy> Don't guess[00:11:08] <shuffle2> it returns a handle, but the handle appears to point to nothing[00:11:43] <shuffle2> its not really opengl, it's creating the wgl context[00:11:57] <shuffle2> that's what i'm failing at[00:12:23] <Madsy> You still didn't answer any of my questions.[00:12:55] <Madsy> If the context isn't created, you can disregard glGetError though[00:13:01] <shuffle2> yeah[00:13:04] <shuffle2> thats what i said[00:13:18] <Madsy> ..[00:16:00] *** in2rd has quit IRC[00:17:43] <shuffle2> ... yourself[00:17:49] <shuffle2> i answered your questions[00:18:04] <shuffle2> if you want to compile it then get dolphin-emu svn and ill send a patch[00:18:12] <shuffle2> other than that i told you what's not working[00:18:43] <TheFlash> shuffle2: Read http://mikeash.com/getting_answers.html[00:20:43] <shuffle2> funny, i only have problems like this on oss channels[00:20:53] *** johndoe has joined ##opengl[00:23:05] <Madsy> Yeah, I guess we're all evil.[00:26:04] <TheFlash> We are not OSS.[00:27:24] <shuffle2> well i was refraining from using the broader word[00:27:40] <shuffle2> but nvm, i cant seem to get help here anyways[00:28:27] <TheFlash> Well, I am using my time to search where the heck is that "rasterwindow" class.[00:28:55] <TheFlash> Oh, register.[00:29:03] <quicksilver> registerwindowclass doesn't return anything at all.[00:29:13] <quicksilver> So I don't really understand your problem description.[00:29:24] <TheFlash> Win32.

And can OpenGL be used as commercially as Direct3D(X)?[10:29:08] <zeroflag> Jimathon: how about C# and XNA? or C# and OpenGL? C++ is the _current_ standard in game development, but everyone who has some kind of common sense is trying to get away from it.[10:29:39] *** dvoid has joined ##OpenGL[10:29:47] <MatthiasM> lol[10:30:03] <zeroflag> Jimathon: as someone who has been programming for years and who has recently picked up 3D programming I can say that C#/XNA is a great place to start - and with that background OpenGL and C++ is much easier to learn.[10:30:49] <Jimathon> I already know some C++ and have "accelerated C++" though?[10:31:03] <zeroflag> especially because C# programmers aren't such jerks who won't help you, and there is actually documentation on XNA other than the specification.[10:31:46] <zeroflag> Jimathon: I know too many people who tried to start with C++. they either end up frustrated or delusional and always ignorant to the fact, that there are better options than C++.[10:31:57] <Jimathon> Kk, Does C# and XNA combine well? And what are you saying? When i've picked up on them it should seem "easy/easier" to pick up C++ and OpenGL/DirectX?[10:32:17] <MatthiasM> C# and XNA locks you into MS platforms[10:32:18] <zeroflag> Jimathon: C# is the primary language for XNA.[10:32:39] <zeroflag> MatthiasM: see it as a stepping stone to start learning programming and 3D...[10:32:50] <Jimathon> Okay, thanks.[10:32:59] <zeroflag> MatthiasM: I tried long and hard with opengl and didn't even understand index buffers... it was much easier with XNA.[10:33:06] <MatthiasM> no - learn C/C++ and OpenGL - most existing code is written in these languages[10:33:37] <Jimathon> Matt, you saying don't learn C# and XNA?[10:33:42] <MatthiasM> yep[10:34:09] <MatthiasM> atleast not as a start - only if someone pays you for it[10:34:30] <Jimathon> :/ I just want to learn C++ (well alot of it in the end) and be able to create commercial games (10 years time or something?)[10:34:42] <zeroflag> argh[10:34:46] <zeroflag> good old language war...[10:34:49] <zeroflag> here we go again.[10:34:56] <zeroflag> it's like this:[10:35:27] <zeroflag> C++ is currently the industry standard. C# is the newcommer.[10:35:54] <zeroflag> C++ has a huge and old crowd of programmers who will flood you with "read this and that book" but will never help you.[10:36:05] <Jimathon> I might do like you said, C# && XNA then C++ and OpenGL[10:36:20] <zeroflag> C# has a friendly and patient community which is mostly still learning themselves.[10:36:24] <MatthiasM> lol[10:36:24] <zeroflag> same with opengl and XNA.[10:37:05] <Jimathon> Is ++ similar to #?[10:37:09] <zeroflag> for example you can start by comparing the MSDN (for XNA and C#) to the documentation you'll find for C++ and OpenGL - that's something C++ and OpenGL can not win.[10:37:46] <zeroflag> Jimathon: the syntax looks similar, but C++ is based on C (hence it's slow to work with and overly complicated) while C# has it's own modern compiler system.[10:38:14] <MatthiasM> Jimathon: # is the shit MS invented to lock devs into their platform[10:38:27] <MatthiasM> it's a bad copy of Java[10:38:45] <zeroflag> Jimathon: long story short: a medium-sized C++ project takes about 5 minutes to compile from scratch, and about 10-30 seconds to rebuild and test (execute after you changed something). C# takes 10-30 seconds to build from scratch, and 1-5 seconds to test.[10:38:54] *** Suprano has joined ##OpenGL[10:39:26] <zeroflag> MatthiasM: shut up with your ignorance and idiotic propaganda. if you know ANYTHING about C# you wouldn't talk like that.[10:39:26] <Jimathon> Okay, I think I'll go C# and XNA then, But return to ++ and GL at a later date?[10:39:36] <zeroflag> Jimathon: yes, that is a sound plan.[10:39:41] <MatthiasM> zeroflag: you know why it compiles so fast ?[10:39:56] <MatthiasM> because the compile is not doing any optimisations[10:40:02] <zeroflag> MatthiasM: yes, because it has a compiler that isn't built for 386s and does understand it's code.[10:40:08] <zeroflag> MatthiasM: that is wrong.[10:40:33] <zeroflag> MatthiasM: the first compiler does general, high-level optimization. something that is hardly possible for C++ because there is no "high level".[10:40:35] *** in2rd has quit IRC[10:40:36] <MatthiasM> look at what it does - it create bytecode - just a mostly 1:1 mapping from source code[10:40:49] <Jimathon> Is it possible to create commercial games with XNA?[10:40:50] <zeroflag> MatthiasM: the second compiler does FAR more optimization than C++... for a realistic build anyway.[10:41:33] <zeroflag> MatthiasM: while you can enable SSE3 for your PC because you know it supports it, you can't enable it on a public build because not everyone has such a PC... I don't have to worry about it, the runtime will enable every optimization possible on the target PC.[10:41:46] <MatthiasM> zeroflag: the amount of optimisation built into .net are very few[10:42:01] <zeroflag> MatthiasM: so while you might get better benchmark results on your highly optimized system, I get better REAL WORLD results.[10:42:40] <zeroflag> MatthiasM: C++ is about 10% faster than C# under perfect circumstances: highly optimized C++ with highly demanding algorithms.[10:42:58] <MatthiasM> well - I use Java - which uses the same approch (it was earlier) and has a more advanced runtime[10:43:11] <zeroflag> MatthiasM: in the real world you don't have highly optimized C++ for compatibility and you don't run highly demanding algorithms all the time.[10:43:31] <zeroflag> MatthiasM: end of the day C# will be just as fast as C++, but a LOT easier to write and port to different platforms.[10:43:41] <Jimathon> I'm guessing you can combine C# and XNA nicely?[10:44:00] <zeroflag> MatthiasM: wrong. the java runtime is what C# was in version 1.1... we're at 3.5/2.0 now.[10:44:09] <zeroflag> Jimathon: as I said, it's the native language for it.[10:44:22] <MatthiasM> zeroflag: lol - c# version only cleaned up the shit they created as 1.x[10:44:27] <zeroflag> Jimathon: you just add reference -> Xna -> go for it.[10:44:45] <zeroflag> MatthiasM: what the hell are you talking about?[10:44:58] <MatthiasM> zeroflag: the first API was a bad clone of win32 API[10:45:11] <MatthiasM> they even used the same error codes for the network functions[10:45:28] <zeroflag> oh, guess why?[10:45:32] <MatthiasM> now they cleaned it up a bit and found some kind of design[10:45:51] <MatthiasM> but it took years - but the runtime they run on is still poor[10:46:00] <zeroflag> that's nonsense.[10:46:09] <zeroflag> the runtime is very solid and powerful.[10:46:24] <zeroflag> the APIs might not be perfect but they are FAR better than anything C++ or C has to offer.[10:46:29] <MatthiasM> so - what type of GC do they run ?[10:46:36] <zeroflag> and the libraries are portable.[10:46:46] <zeroflag> depends on the runtime.[10:48:20] <zeroflag> I think mono recently implemented a new GC...[10:48:29] <zeroflag> but even with the old GC they could compete with java...[10:48:31] <MatthiasM> mono is 5+ years behind anything else[10:48:39] <zeroflag> you think?[10:48:50] <zeroflag> mono still beats java on language features. :P[10:49:11] <MatthiasM> yes - even a naive on the fly .net -> java bytecode translater outperforms it[10:49:13] <zeroflag> here's a clue: List<int>[10:49:18] <MatthiasM> lol[10:49:48] <zeroflag> or how about list.Find(item => item.IsSomething);[10:50:23] <zeroflag> unlike java, C# has real generics and real lambda expressions.[10:50:32] <zeroflag> and before you start about templates and C++...[10:50:42] <MatthiasM> well - language features alone doesn't mean that you can write better apps[10:51:02] <zeroflag> typeof(List<>).Specialize(someRuntimeType).CreateInstance();[10:51:27] <zeroflag> I admit, those are my own extensions, but they all build on the C# type system.[10:51:43] <zeroflag> some language features do.[10:51:45] <MatthiasM> and?

show me your app running on a mac[11:00:30] <MatthiasM> or your C app on a ppc :DD[11:00:32] <zeroflag> I will as soon as I find someone who can help me with the opengl backend.[11:00:55] <zeroflag> but I could create a backend to run on the xbox...[11:01:21] <zeroflag> or I could swap in the Axiom backend and run it on linux...[11:01:44] <MatthiasM> can you do it without changing any of your code ?[11:01:50] <zeroflag> heh.[11:01:57] <MatthiasM> I can with Java :)[11:02:00] <zeroflag> see, now I know that you know far less about software design than me...[11:02:03] <MatthiasM> not even recompiling[11:02:06] *** Ingenu has joined ##OpenGL[11:02:15] <zeroflag> there's a difference between portable code and platform independent code.[11:02:34] <zeroflag> and there's a difference between java's approach to both and C#'s approach...[11:02:35] <Jimathon> XNA mod tool like nices[11:02:56] <Jimathon> *looks nice[11:03:20] <zeroflag> java just puts a ton of limitations on the programmer, reduces performance, and then runs regardless if the platform is a windows vista, or a nokia phone...[11:03:30] <MatthiasM> zeroflag: if you have to modify your code - then it's not fully portable - if you only have to recompile then it's portable - if you can just run it then it's platform free[11:03:55] <zeroflag> C# itself runs on any platform you want, but it CAN use native platform libraries to get the best performance...[11:04:00] <MatthiasM> java performance is better then c# - esp in the enterprice applicaion area[11:04:23] <zeroflag> so if I use the XNA backend with the XNA window handler, it'll run on windows and/or xbox...[11:04:57] <zeroflag> if I use a OpenGL backend with a SDL window handler, it'll run on linux, windows and on any platform that can provide the libraries.[11:05:09] <zeroflag> MatthiasM: but not on 3D programming.[11:05:18] <MatthiasM> zeroflag: for Java I use LWJGL - it provides OpenGL and OpenAL on windows, linux, mac and solaris - for 32/64 bit and x86/ppc[11:05:50] <MatthiasM> and that is one API - not 10 different - it's even the same lib[11:05:52] * zeroflag giggles[11:06:26] <zeroflag> ok, so how do you integrate your LWJGL with any native UI?[11:07:02] <MatthiasM> LWJGL creates a OpenGL display - from there it's just OpenGL calls[11:07:11] <zeroflag> it's the same thing that makes java applications look ugly and slow on windows: it's not native, it's java.[11:07:30] <MatthiasM> or you can embed a OGL display into a Swing frame[11:07:41] <zeroflag> yeah, and swing is ugly and slow, as I said.[11:07:44] <MatthiasM> well - try it :)[11:07:49] <zeroflag> I have.[11:07:51] <zeroflag> and it is.[11:07:59] <MatthiasM> http://twl.l33tlabs.org/ :)[11:08:00] <Mazon> in 1998 ?[11:08:01] <zeroflag> that's the thing I'm talking about...[11:08:21] <MatthiasM> Mazon: hi :)[11:08:25] <zeroflag> java is very compatible, but it isn't native anywhere.[11:08:35] <MatthiasM> it is - if you want[11:08:40] <Mazon> so the dlls are just for fun ?[11:08:55] <zeroflag> no it isn't, especially not without sacrificing a lot of it's features.[11:09:10] <Mazon> you are aware that AWT ISSSS native components?[11:09:44] <Ingenu> encapsulating native components might not lead to best performance[11:09:46] <zeroflag> Mazon: did I mention "not without sacrificing a lot of its features"?[11:09:54] <Ingenu> that said, we're off topic, aren't we ?[11:09:58] <MatthiasM> zeroflag: until you can show me on C# app that runs on different operating system and uses some 3D HW - without changing the app's source code - it's not portable[11:10:09] <zeroflag> we are, very much so.[11:10:25] <zeroflag> MatthiasM: then go have a look at Axiom.[11:10:30] <Mazon> ingenu: aye, just trying to kill a rant[11:10:54] <zeroflag> MatthiasM: it's 3D, and if you use the opengl backend it runs very well on windows, linux and (if you're lucky) even on macosx...[11:11:07] <Ingenu> JAVA vs C# sounds a bit like OpenGL vs Direct3D to me[11:11:24] <Ingenu> :p[11:11:26] <zeroflag> there's no OpenGL vs Direct3D IMO.[11:11:46] <MatthiasM> Ingenu: well - I'm not aware of a working D3D interface for Java[11:11:53] * Mazon notes that axiom doesn't work on solaris :p[11:11:57] <zeroflag> both have dreadful APIs but OpenGL is portable and plain C. so OpenGL wins on the "bad but at least"-front.[11:12:32] <zeroflag> Mazon: how so? it's still a *nix, you can get X and OpenGL drivers as well as Mono, so it'll work.[11:13:02] <zeroflag> XNA isn't half as portable, but at least the API isn't as dreadful.[11:13:29] <zeroflag> so OpenGL for the professionals, XNA for beginners and for simplicity. Direct3D for people who don't know better.[11:14:08] <Ingenu> not really, D3D for games, XNA for beginners/tests, OpenGL for heavy industry only[11:14:18] <MatthiasM> and C# for people who belive that it's a compiled language who claim Java is interpreted :DD[11:14:38] <zeroflag> well, without the OpenGL redesign you are right... sadly...[11:14:50] <Ingenu> JAVA isn't compiled for sure, that's why SUN sued MS in the past[11:14:51] <zeroflag> with the redesign OpenGL should get back into games...[11:15:02] <Ingenu> (I know of HotSpot ty)[11:15:09] <MatthiasM> Ingenu: like C#[11:15:21] <zeroflag> MatthiasM: both are (JIT) compiled languages.[11:15:30] <MatthiasM> zeroflag: there won't be a huge API change - read the opengl website[11:15:55] <zeroflag> I thought they just delayed it? :\[11:16:04] <Ingenu> more or less[11:16:08] <Ingenu> there's the deprecation thing[11:16:09] <zeroflag> geez, we need a new portable API...[11:16:18] <jezek2> zeroflag: btw there is SWT which uses native widgets in Java[11:16:34] <MatthiasM> and SWT is a can of worms for portability[11:16:36] <Ingenu> but all in all, it's a battle that has been fought already, D3D for games is a fact, only iD Software keeps using OpenGL[11:16:36] <zeroflag> jezek2: did I mention sacrificing features?[11:17:05] <Mazon> what IS sacrificing features ?[11:17:25] <zeroflag> Mazon: like portability.[11:17:27] <Ingenu> can I watch the sacrifice ?[11:17:36] <Ingenu> oh no, it's not a real one... :p[11:17:37] <zeroflag> Ingenu: if you bring the dagger.[11:17:41] <Mazon> thats not sacrificesd - I think we established thar ?[11:17:46] <MatthiasM> let's sacrify zeroflag :)[11:17:57] <Ingenu> go play L4D guys, there's been an update[11:18:06] <Ingenu> kill zombies, will make you happier[11:18:15] <Mazon> actually, I hate zombie games :p[11:18:38] <MatthiasM> the l4kd was nice :)[11:19:05] * Mazon still doesn't understand the attitude against interpretet code[11:19:14] <Mazon> even Apple is doing it in their OpenGL stack[11:19:44] <MatthiasM> it's just that nearly all C# users think that they don't use interpreted code :)[11:20:17] <Mazon> well, says more about them ..[11:20:28] <zeroflag> cool.[11:20:32] <zeroflag> mono runs on Wii. oO[11:21:33] <Mazon> well, then does java[11:21:46] <zeroflag> I don't care about java.[11:21:54] <zeroflag> java is the wrong language for games, so just drop it.[11:22:07] <Mazon> I dont care about mono but that didn't prevent you from talking about it ;)[11:22:23] <zeroflag> true, wrong channel. oO[11:22:32] * Mazon nods[11:22:49] <jezek2> zeroflag: hmm interesting there are many games in java already, why you think it's wrong? :)[11:23:29] <zeroflag> don't know? because of java's dreadful interface to existing C APIs?[11:23:38] <Mazon> jezek2: already made up his/her mind - so let it go[11:23:56] <zeroflag> because of java's compatibility>performance approach?[11:26:47] <jezek2> it's not problem, proved by many games :)[11:27:25] *** zeroflag has left ##opengl[11:28:03] <Ingenu> all that valuable internet bandwidth wasted... ;p[11:35:53] <Mazon> bits are meant to be wasted ![11:35:54] *** Gorgoroth has joined ##OpenGL[11:38:00] *** korff_home has quit IRC[11:38:45] *** korff_home has joined ##OpenGL[11:44:01] *** dolphin has quit IRC[11:44:15] *** elite01 has joined ##opengl[11:44:18] *** dolphin has joined ##OpenGL[11:44:19] *** elite01 has joined ##opengl[11:48:16] *** Burga has joined ##OpenGL[11:48:30] *** Jimathon has quit IRC[11:53:53] *** groton has joined ##OpenGL[12:01:27] *** sohail has quit IRC[12:02:39] *** Yustme has joined ##OpenGL[13:05:07] *** strombom has quit IRC[13:23:57] *** Xmas| has joined ##OpenGL[13:32:28] *** LtJax has joined ##opengl[13:35:35] *** yno has joined ##OpenGL[13:35:47] <yno> hi[13:37:41] <FireKitten> hi :)[13:44:49] *** UUncia has quit IRC[13:46:21] *** _THEGOD__ has joined ##OpenGL[13:46:24] <_THEGOD__> hi[13:46:49] <_THEGOD__> is there something for deleting any tecture loaded to vga buffer ?[13:47:08] <_THEGOD__> because it looks like y graphics card has limited buffer for textures .[13:47:35] <_THEGOD__> do i hawe to spesify all textures one by one ?[13:47:42] <_THEGOD__> using glcleartextures ?[13:47:53] <_THEGOD__> i hope there is a easy way.[13:47:59] <_THEGOD__> to delete anyting on buffer .[13:48:09] <_THEGOD__> including missing parts.[13:48:18] <_THEGOD__> i dont want to leawe anything on buffer.[13:48:24] <_THEGOD__> hello .[13:48:29] <LtJax> hello[13:48:37] <_THEGOD__> hi.[13:48:56] <LtJax> there's no glClearTextures or something similar[13:49:04] <_THEGOD__> hm...[13:49:08] <_THEGOD__> wait.[13:49:11] <LtJax> the driver should however clear all the resources up one you delete a context[13:49:30] <LtJax> also, things are automatically swapped in and out of the graphics card's memory[13:49:43] <_THEGOD__> context ?
