• Good evening everyone!

I was wondering if there is something equivalent of  GL_NV_blend_equation_advanced for AMD?
Basically I'm trying to find more compatible version of it.

Thank you!

• Hello guys,

How do I know? Why does wavefront not show for me?
I already checked I have non errors yet.

And my download (mega.nz) should it is original but I tried no success...
- Add blend source and png file here I have tried tried,.....

PS: Why is our community not active? I wait very longer. Stop to lie me!
Thanks !

• I wasn't sure if this would be the right place for a topic like this so sorry if it isn't.
I'm currently working on a project for Uni using FreeGLUT to make a simple solar system simulation. I've got to the point where I've implemented all the planets and have used a Scene Graph to link them all together. The issue I'm having with now though is basically the planets and moons orbit correctly at their own orbit speeds.
I'm not really experienced with using matrices for stuff like this so It's likely why I can't figure out how exactly to get it working. This is where I'm applying the transformation matrices, as well as pushing and popping them. This is within the Render function that every planet including the sun and moons will have and run.
if (tag != "Sun") { glRotatef(orbitAngle, orbitRotation.X, orbitRotation.Y, orbitRotation.Z); } glPushMatrix(); glTranslatef(position.X, position.Y, position.Z); glRotatef(rotationAngle, rotation.X, rotation.Y, rotation.Z); glScalef(scale.X, scale.Y, scale.Z); glDrawElements(GL_TRIANGLES, mesh->indiceCount, GL_UNSIGNED_SHORT, mesh->indices); if (tag != "Sun") { glPopMatrix(); } The "If(tag != "Sun")" parts are my attempts are getting the planets to orbit correctly though it likely isn't the way I'm meant to be doing it. So I was wondering if someone would be able to help me? As I really don't have an idea on what I would do to get it working. Using the if statement is truthfully the closest I've got to it working but there are still weird effects like the planets orbiting faster then they should depending on the number of planets actually be updated/rendered.

• Hello everyone,
I have problem with texture

• Hello everyone
For @80bserver8 nice job - I have found Google search. How did you port from Javascript WebGL to C# OpenTK.?
I have been searched Google but it shows f***ing Unity 3D. I really want know how do I understand I want start with OpenTK But I want know where is porting of Javascript and C#?

Thanks!

Hello,

Does anyone have any up-to-date statistics on what percentage of the x86 based desktop PC market is occupied by non-Microsoft operating systems, and thus for which the use of OpenGL would be basically mandatory? Also, do most of you OpenGL programmers compile with GCC and if so, what is your preferred IDE? If you produce work for both Windows and Non-Windows, do you use VC to compile for windows and/or use DirectX for windows, while using OpenGL for the rest, or do you just use the GCC/GL combo for all your work?

Last month's Steam Hardware Survey indicates that 5% of Steam users run Macs. Perhaps this isn't the greatest indicator of overall Mac/Linux marketshare among gamers, but I'd expect that 5% figure to be a reasonable ballpark for the size of the market you are looking at.

Also, do most of you OpenGL programmers compile with GCC and if so, what is your preferred IDE?[/quote]
I gave up on cross-platform C++ IDEs a long time ago. Visual Studio is the gold standard, and XCode is not bad once you get used to it, but integrating the two together in a single project is a pain - and I seldom find other IDEs to be worth the hassle.

If you produce work for both Windows and Non-Windows, do you use VC to compile for windows and/or use DirectX for windows, while using OpenGL for the rest, or do you just use the GCC/GL combo for all your work?[/quote]
I have no interest in writing all my code twice. OpenGL works well enough on Windows as well.

http://www.netmarketshare.com/operating-system-market-share.aspx?qprid=10 has some data about OS market share, which I'd assume would be at least fairly accurate, although with linux, dual booting, etc it's impossible to tell exactly.

I program with openGL, using MSVC on windows and GCC/Eclipse on linux

I develop for both Linux and Windows pre-8 and primarily OpenGL, but since I use a non-platform-dependent API for these platform-specific parts, which is then compiled (or linked at run-time using DLL's/SO's) into platform-dependent source using macros, I can easily compile for a new platform, say Direct3D or MacOS, should I wish to do so later on. This is a common way of hiding away platform-dependent source. For reference, L. Spiro has posted a neat little article regarding the compile-time macro solution: http://lspiroengine.com/?p=49.

P.S. I fancy CodeBlocks too much to let VS get in my way on Windows :-)

macs have at most 5%, but you can only use OGL 3.x
linux based systems have at most 1%, and latest OGL

For cross platform development you need to use cross platform libraries, and build with non-cross platform IDEs and compilers. For cross platform libraries your best choice IMO would be SFML + OGL + GLEW (and other libs like freetype, freeimage, assimp etc. if needed)
For example I chose cmake to create both a makefile (so yeah gcc/g++) on Linux and a Visual Studio solution on Windows. As far as I know it works for mac too.
On linux your best choice is cmake and kdevelop IMO, but 100 developers will give you 100 answers to this question. You still have other IDEs like Eclipse and Qt Creator.
In my experience OGL has been enough for everything, so I don't see why you'd use DX even on Windows (why would you develop the same thing twice?).

People,

Thank you for your responses. I feel that there is merit to using D3D on Windows because the drivers are updated more frequently and the customer service from the graphics card manufacturers is much better. The fact that companies like Blizzard use D3D on Windows and GL on Mac is a form of proof of this concept.

I have decided to download and use Code::Blocks with the latest GCC collection. I do not really want to pay the $500 for MSVC12 unless it is totally necessary. I want to do some emperical research into why MSVC is considered the "Gold Standard." One possibility is that coders are "raised" on Microsoft code from past decades and they just don't want to change the way they do things. For example, most game writing books are written using D3D and very Windows-centric code. The other possibility is that MSVC offers features that increase the productivity of programmers and/or aid in creativity. My hypothesis is that the former is true, but I am going to download and use GCC on Windows now to prove that. Another thing I am going to do is setup my rig to dual boot into Linux and learn Linux as well as I can. I believe that Windows 8 is the beginning of a long-term migration of non-Mac x86 users to the "free" space. I don't think it will happen fast, but I actually believe that the game development community itself (namely indies, but larger companies eventually) will be the catalyst for the change. If Windows becomes a closed system like it is rumored to become, then there will be no more bastion of censorship-free and middleman free game development platforms (other than web, but there are many limitations on web-games). Thus, game developers will move to Linux to gain the freedom (financial and otherwise) offered by the platform, and some gamer will want to play a Linux only game and move over, and then another, and then another. Unless I am mistaken, there is no reason at all why Windows should be the dominant platform other than network effect and historical reasons. To me, this is not enough of a reason to choose the platform for development. If Linux had a 50% share think of how much better of a world we would be living in. Microsoft would be forced to be more standards compliant and all cross-platform development would be made easier, not to mention the better coding practices that this diversification would encourage. I believe that the Linux community, while small, could be the best place for Indie developers to focus now because of the exponential growth that it is poised to experience. When it blows up, the big guys will be there very quickly, so there are benefits to be had of getting into the space now. Just my two cents. -Dave Ottley #### Share this post ##### Link to post ##### Share on other sites It's true that once I developed games under MS platform, and I have a DirectX programming experience of 3 years. But I will further look into the mystery of CG, I give up MS and D3D, and move into Linux. Now I use Ubuntu and QtCreator as my developing environment, recently I am learning OpenGL Super Bible, the sample code works fine. #### Share this post ##### Link to post ##### Share on other sites If Linux had a 50% share think of how much better of a world we would be living in. Microsoft would be forced to be more standards compliant and all cross-platform development would be made easier, not to mention the better coding practices that this diversification would encourage. I think that's a very optimistic and unrealistic viewpoint. Split shares of a market has shown us time and time again in the technology field that not only do standards-compliant products not become more the norm, they tend to become less the norm as the competitors independently develop and implement a 'standard' to get a leg up on the other guys who are waiting for a committee to approve and tweak things just right. Internet Explorer vs. Netscape Navigator/Communicator. Horrible divergent html paths that have yet to be resolved 15 years later. iOS vs. Android. Virtually no interoperability between the two dominant mobile platforms.. 3rd party options that will individually compile to each is about as close to bridging that gap as exists. Maybe HTML 5 will grow into being closer to a true cross platform solution. Not so 50/50 examples: OSX vs. Windows. MySpace vs. FaceBook then FaceBook vs. Google + MS Office vs. Lotus Notes Java vs. C# Verizon Wireless vs. AT&T (cmda vs. gsm) (hey, you got one here, they're both headed to LTE as the 4G solution) Hotmail vs. GMail Mercurial vs. Git So while I definitely don't agree that more standards would be drawn up and agreed to, I definitely do want Linux to continue to grow and thrive. I think having competition where people/companies are taking different approaches at the same problem is a great free-market style approach that leaves us with options and with better products as a result. One little story on that note is I recall how confused and then annoyed I was with GMail tagging instead of using folders. And now when I attempt to clean up my Hotmail account, I feel like I have so much less control having to choose 1 folder to put stuff in rather than being able to apply multiple tags and then view any tag that I care to. Tags > Folders all the way. #### Share this post ##### Link to post ##### Share on other sites I have decided to download and use Code::Blocks with the latest GCC collection.

It's actually the case that the latter of your two possibilities is true; MSVC - while admittedly lagging behind in standards compliance (it's getting better though) - is ahead on productivity and is widely considered to have the best debugger currently available on the planet. The entry level is very accessible too - Express editions will cost you absolutely nothing and are quite well-featured.

The express editions are free, and perfectly usable.

Don't look at me then. I'm from a very Mac/linux centric worldview, and even I admit that Visual Studio is the gold standard of IDEs.

Seriously, download the express edition and give it a whirl - XCode comes somewhere close in terms of usability (especially since Apple threw out GCC and adopted Clang instead), but no other IDE is even in the same league.
