OpenGL
Opengl Linux

10 posts in this topic

So, this is a pretty dumb question.

 

But how do I get Opengl 3.3+ running on linux.

 

Atm glxinfo gives me the info: 3.0 Mesa 8.0.5

My graphics driver is Nvidia geforce GT 630M (2GB)

 

I've tried (and still am trying) to get Mesa 9.2.3 running.

I've got problems installing it.

 

I do know that Mesa 10 will be released quite soon, which supports 3.3.

But there have to be different options.

 

I also found the linux x64 (amd64/em64t) display driver on Nvidia website. But I don't know whether it supports opengl 3.3+

 

What I do know is that on my windows partition I got opengl 4.0 running.

Not sure why would you want to use mesa if you have a good graphics card? Just install nvidia's graphics drivers, preferably through your distro's package manager.

The process for getting OpenGL running on any platform is pretty much the same, however, with a GL 3.2+ context , a little more work is involved.

1. Create a system specific window using the system provided api.

2. Create an OpenGL context from the previously provided window device context.

There at one of examples showing how to create OpenGL context....

Some day I will get these problems people speak about using nVidia's installer and I'll share their pain, but for me right now, it can't get easier than sh'ing the installer and let it do its job.

 

What actually never worked for me is the dkms that should, in theory, automagically recompile the driver each time I upgrade the kernel. Probably I'm missing something though...

Thanks for all the responses

 

Mesa is a software renderer http://www.mesa3d.org/

To get OpenGL to work on linux can be an adventure sometimes, since as a developer it's likely you want the latest

In my case I went the hardcore route and failed many times (I had to use terminal shell to fix xorg after completely breaking it)

 

So goes my warning: Installing the nvidia linux driver manually IS NOT WORTH IT

 

Fortunately if you have ubuntu, there are some simple and safe ways:

 

1. Use the nvidia-current branch (which is new enough for most cases)

You will find it in the Ubuntu Software Center

 

2. Use the edgers repo (from terminal):

a) Add the edgers repo

sudo apt-add-repository ppa:xorg-edgers/ppa

b) Update index files

sudo apt-get update

c) Install any of the nvidia packages, such as the very latest (as of this post):

sudo apt-get install nvidia-331

 

I'm using debian weezy.

And yes, I tried to install manually. (so bad)

Somehow I messed up my whole system.

Everything was broken, I could barely login (even through recovery mode)

 

I had to reinstall the system.

 

I'm searching around the web how I could install the drivers.
But each time I try something, x won't run.

Hmm those ppa etc. Nvidia repos never worked for me. I go with default and later update manually. Currently Nvidia is at OpenGL 4.3 or even 4.4.

Mesa does 3D acceleration for many chips.

 

Um, no.  Well, sorta, in that it can use LLVMpipe to JIT the software rendering.  Generally, on Linux, the hardware does the hardware acceleration (using the proprietary blobs or the free driver equivalents).  Like on Windows, you link against the GL API provided by Mesa but the runtime is provided by the hardware vendors (through kernel DRM -- direct rendering module).  That's one reason why installing the nVidia drivers from nVidia is bad: they blow away the Mesa libraries, which means if you're a developer and upgrade the -dev package you will experience open running sores and purulent boils.

Um, yes. Well, sorta. Most of the open source hardware 3D drivers use Mesa as a front end - a bit like Microsoft writing D3D and the hardware manufacturers only needing to write a relatively small hardware specific bit rather than a full 3Dstack like they do with OpenGL.

      Hello

      I am working on a recent project and I have been learning how to code in C# using OpenGL libraries for some graphics. I have achieved some quite interesting things using TAO Framework writing in Console Applications, creating a GLUT Window. But my problem now is that I need to incorporate the Graphics in a Windows Form so I can relate the objects that I render with some .NET Controls.

      To deal with this problem, I have seen in some forums that it's better to use OpenTK instead of TAO Framework, so I can use the glControl that OpenTK libraries offer. However, I haven't found complete articles, tutorials or source codes that help using the glControl or that may insert me into de OpenTK functions. Would somebody please share in this forum some links or files where I can find good documentation about this topic? Or may I use another library different of OpenTK?

      Thanks!

      Hello, I have been working on SH Irradiance map rendering, and I have been using a GLSL pixel shader to render SH irradiance to 2D irradiance maps for my static objects. I already have it working with 9 3D textures so far for the first 9 SH functions.
      In my GLSL shader, I have to send in 9 SH Coefficient 3D Texures that use RGBA8 as a pixel format. RGB being used for the coefficients for red, green, and blue, and the A for checking if the voxel is in use (for the 3D texture solidification shader to prevent bleeding).
      My problem is, I want to knock this number of textures down to something like 4 or 5. Getting even lower would be a godsend. This is because I eventually plan on adding more SH Coefficient 3D Textures for other parts of the game map (such as inside rooms, as opposed to the outside), to circumvent irradiance probe bleeding between rooms separated by walls. I don't want to reach the 32 texture limit too soon. Also, I figure that it would be a LOT faster.
      Is there a way I could, say, store 2 sets of SH Coefficients for 2 SH functions inside a texture with RGBA16 pixels? If so, how would I extract them from inside GLSL? Let me know if you have any suggestions ^^.

      EDIT: I thought this was restricted to Attribute-Created GL contexts, but it isn't, so I rewrote the post.
      Hey guys, whenever I call SwapBuffers(hDC), I get a crash, and I get a "Too many posts were made to a semaphore." from Windows as I call SwapBuffers. What could be the cause of this?
      Update: No crash occurs if I don't draw, just clear and swap.

      Hey devs!
       
      I've been working on a OpenGL ES 2.0 android engine and I have begun implementing some simple (point) lighting. I had something fairly simple working, so I tried to get fancy and added color-tinting light. And it works great... with only one or two lights. Any more than that, the application drops about 15 frames per light added (my ideal is at least 4 or 5). I know implementing lighting is expensive, I just didn't think it was that expensive. I'm fairly new to the world of OpenGL and GLSL, so there is a good chance I've written some crappy shader code. If anyone had any feedback or tips on how I can optimize this code, please let me know.

Or am I just being unrealistic about what I can do? Thanks in advance

      Hi,
      Not sure to post at the right place, if not, please forgive me...
      For a game project I am working on, I would like to implement a 2D starfield as a background.
      I do not want to deal with static tiles, since I plan to slowly animate the starfield. So, I am trying to figure out how to generate a random starfield for the entire map.
      I feel that using a uniform distribution for the stars will not do the trick. Instead I would like something similar to the screenshot below, taken from the game Star Wars: Empire At War (all credits to Lucasfilm, Disney, and so on...).

      Is there someone who could have an idea of a distribution which could result in such a starfield?
      Any insight would be appreciated
