I'm trying to run OpenGL 3 programs but I'm not sure which implementation I'm using and probably set it up wrong. (I'm a DirectX programmer) While trying to run these demos:
https://github.com/tomdalling/opengl-series/archive/master.zip.
I get this exception:
ERROR: WGL: OpenGL profile requested but WGL_ARB_create_context_profile is unavailable
This machine is Windows 7 with a 1023MB NVIDIA GeForce GT 520M (Dell) card. Has anyone else seen this error?
I think I know exactly what the issue is.
Most laptops have two graphics cards: A dedicated card (GeForce GT 520M), and an integrated card (Intel HD).
Your integrated card only supports up to OpenGL 3.1, while these demos are requesting OpenGL 3.2.
All you need to to is go into the Nvidia control panel, go into 'Manage 3D Settings', then set the preferred graphics processor to 'High-Performance Nvidia processor'.
After that, the demos should run correctly.

I want to write a program with OpenGL version 4. The currently installed version of OpenGL is 2.1.0 on my computer. I checked for a way to install the latest version of OpenGL, but in online articles it is said that the only way of updating OpenGL libraries is by updating the graphics card driver software.
I have a laptop with Mobile Intel(R) 4 Series Express Chipset Family graphics card. The last update was released in 2010, and it looks like to be abandoned.
Is it possible to write high version OpenGL software with a bad graphics card? I don't care if my program will be running with low FPS rate or be very sluggish on my hardware. I just would like to know if it is technically possible.
Your graphics card must support the OpenGL 4 version to develop with it. It is mandatory that the hardware (graphic card) is compatible with the OpenGl version you want to develop and the driver installed in your system allows the graphic card to use that version.
Supported cards for openGL 4 (Wikipedia):
Nvidia GeForce 400 series, Nvidia GeForce 500 series, Nvidia GeForce
600 series, Nvidia GeForce 700 series, ATI Radeon HD 5000 Series, AMD
Radeon HD 6000 Series, AMD Radeon HD 7000 Series. Supported by Intel's
Windows drivers for the Haswell's integrated GPU.
In your case your graphic card and driver only allows openGl 2.1.
Nowadays almost any graphic card for 40/50 Euros is capable to run openGl 4 (but change it on the laptop usually is not possible)

We began learning OpenGL at school and, in particular, implemented a .obj mesh loader. When I run my code at school with quite heavy meshes (4M up to 17M faces), I have to wait a few seconds for the mesh to be loaded but once it is done, I can rotate and move the scene with a perfect fluidity.
I compiled the same code at home, and I have very low performances when moving in a scene where heavy meshes are displayed.
I'm using the 3.0 Mesa 10.1.3 version of OpenGL (this is the output of cout << glGetString(GL_version) << endl) and compiling with g++-4.9. I don't remember the version numbers of my school but I'll update my message as soon as possible if needed. Finally, I'm on Ubuntu 14.04 my graphic card is a Nvidia Geforce 605, my CPU is an Intel(R) Core(TM) i5-2320 CPU # 3.00GHz, and I have 8Go RAM.
If you have any idea to help me to understand (and fix it) why it is running so slowly on a quite good computer (certainly not a racehorse but good enough for that), please tell me. Thanks in advance !
TL;DR: You're using the wrong driver. Install the proprietary, closed source binary drivers from NVidia and you'll get very good performance. Also with a GeForce 605 you should get some OpenGL-4.x support.

That's your problem right there. The open source "Noveau" drivers for NVidia GPUs that are part of Mesa are a very long way from offering any kind of reasonable HW acceleration support. This is because NVidia doesn't publish openly available documentation on their GPU's low level programming.
So at the moment the only option for getting HW accelerated OpenGL on your GPU is to install NVidia's proprietary drivers. They are available on NVidia's website; however since your GPU isn't "bleeding edge" right now I recommend you use those installable through the package manager; you'll have to add a "nonfree" package source repository though.
This is in stark contrast to the AMD GPUs which have full documentation coverage, openly accessible. Because of that the Mesa "radeon" drivers are quite mature; full OpenGL-3.3 core support, with performance good enough for most applications, in some applications even outperforming AMD's proprietary drivers. OpenGL-4 support is work in progress for Mesa at a whole and last time I checked the "radeon" drivers' development was actually moving at a faster pace than the Mesa OpenGL state tracker itself.
Ok so I'm trying to use the tutorials at: http://arcsynthesis.org/gltut/ but I keep getting an error message that pops for like a second saying "Unable to create OpenGL 3.3 context (flags 1, profile 1)", there's also a bunch of pdb files missing. I did download the newest drivers for both graphics cards on my laptop (that is both the Intel(R) HD Graphics 3000 and the NVIDIA GeForce GT 540M) and I did launch a software called "OpenGL Extensions Viewer", and it displays that I should be able to run OpenGL version 3.1
NOW, I guess is that some would now say that perhaps my card can't run 3.3, but:
1) My card is said to support 4.0 :
http://www.notebookcheck.net/NVIDIA-GeForce-GT-540M.41715.0.html
2) There are people who say that "Any hardware that supports OpenGL 3.1 is capable of supporting OpenGL 3.3. "
OpenGL 3.+ glsl compatibility mess?
3) And finally... A YEAR AGO, I GOT IT TO RUN! Seriously, I got it to work after 2 months of trying. I'm even using some old project files from that time and they sadly won't launch anymore because of the same mistake... I did format since then.
I recall that last time, it was a whole series of things that I tried... like disabling one graphic card to be able to update the other... or maybe it was that I used some different diagnostic, which someone online advised saying that "if that program detects that the OpenGL isn't working properly, it'll fix it".
Right now I'm busy with other homework, so if anyone at all has any suggestions what this could be about, please tell!
I'm developing a 3D stereoscopic OpenGL app specifically for Windows 7 and nVidia Quadro K5000 cards. Rendering the scene from left and right-eye perspectives using glDrawBuffer(GL_BACK_LEFT) and glDrawBuffer(GL_BACK_RIGHT) works fine, and the 3D effect is displayed nicely.
While this works, I'd like to use nVidia's nSight Graphics local debugging. However, I get the error "Cannot enter frame debugging. nSight only supports frame debugging for ... OpenGL 4.2. Reason: glDrawBuffer(bufs[i] = 0x00000402)"
If the calls to glDrawBuffer are removed, nSight local debugging works.
Going through the OpenGL 4.2 spec, DrawBuffer is described in section 4.2.1
So, two questions:
1) Is there some other way (besides DrawBuffer) to specify BACK_RIGHT or BACK_LEFT buffers for drawing to quad-buffers?
2) Is nSight capable of doing frame-level debugging on quad-buffered stereoscopic setups? If so, how?
I want to start with my webGL project and minimal require is my graphic card support openGL 2.0.
Problem exist because i have intel laptop with integrated intel 965 graphic media accelerator and driver is up to date and it support openGL 1.5.
Is there any solution how to update my graphic carf to support 2.0? Is this possible?
Okay. just stay patient actually because ANGLE is coming. It seems to me that your hardware is able to run directX 9 and ANGLE is a project from google to allow webgl support from directX. But as the others say, you can't upgrade opengl drivers just like that. Or you could try MESA in the firefox build.
For more information, see Learningwebgl.com.
Sadly no. With a little more effort you can still develop against opengl 2.0 but you'll need to use another machine (or just buy a better graphics card) to test anything 2.0 specific (pixel shading for instance).
Ok, that's not entirely true. You could download the mesa library and compile it for win32 and get some of the opengl 2.0 functionality emulated in a software renderer but it would be very slow.
It's possible that updating drivers might help some, but probably won't make that jump. Otherwise, you could use something like Mesa3D, which does the rendering in software. It can be slow, but does support up through OpenGL 2.1 (including shaders), if memory serves.
If there's no other way, you could try http://www.mesa3d.org/ . I haven't followed this project for quite some time, but apparently they currently provide OpenGL 2.1 software rendering.
I just updated drivers my HP 6710b with Mobile Intel 965 Express Chipset -- and now WebGL is working in Firefox 4 RC1!
I put instructions on this site.
It is not pretty but it works!
angleproject is your best bet. Check out which exact 965 card you have from here (search for 'intel gma' in wikipedia), which also lists the OpenGL support version for these cards. It might take a couple of months though before you can use angleproject to accelerate your WebGL application.
I have a slightly newer 4500MHD, and I have the same problem. WebGL works on Firefox 3.7a4, but fails in the later versions a5 and a6. I had to use the latest drivers from Intel which claim to support OpenGL 2.0. The Microsoft drivers don't ship with OpenGL support.
I have reported a issue in the Firefox https://bugzilla.mozilla.org/show_bug.cgi?id=570474. It looks like support for Intel cards might be fixed by the time the releases are in beta.
