OpenGL

OpenGL (Open Graphics Library) is a cross-language, cross-platform application programming interface (API) for rendering 2D and 3D vector graphics.

Installation

To run any application that uses OpenGL you will need to install driver(s) for your hardware (either GPUs or CPUs)

• mesa is an open-source OpenGL implementation, continually updated to support the latest OpenGL specification. It has a collection of open-source drivers for Intel graphics, ATI, AMD, AMD PRO, and NVIDIA GPUs and also provides software rasterizers, The included drivers in the package are
  • i915 : for GMA 916G as well as the i830, i845 and i865 integrated GPU series.
  • i965 : for Intel’s Gen 4 hardware and later. It is officially supported by Intel.
  • iris : for Intel’s Gen 8 hardware and later. It is officially supported by Intel.
  • r100 : for AMD’s Radeon R100 GPU series.
  • r200 : for AMD’s Radeon R200 GPU series.
  • r300 : for AMD’s Radeon R300, R400, and R500 GPU series.
  • r600 : for AMD’s Radeon HD 2000 GPU series and later. It is officially supported by AMD.
  • radeonsi : for AMD’s Southern Island GPUs and later. It is officially supported by AMD.
  • nouveau : Nouveau is the open-source driver for NVIDIA GPUs.
  • virgl : is a virtual GPU driver for sharing a GPU with a host for virtual machines.
  • svga : for VMware virtual GPUs.
  • zink : is a Gallium driver, it can be used to run OpenGL on vulkan.
  • swrast : Legacy software rasterizer.
  • softpipe : Software rasterizer, a reference Gallium driver.
  • llvmpipe : Software rasterizer, uses LLVM for x86 JIT code generation and is multi-threaded.
  • swr : High performance software rasterizer that uses AVX and AVX2 CPU instructions, also known as OpenSWR.

• nvidia-utils is proprietary driver for NVIDIA GPUs.

• amdgpu-pro-libglAUR is proprietary driver for AMD PRO GPUs.

Verification

To verify your OpenGL installation you can use mesa-demos glxinfo and you should get output like this :

(with different values depending on your setup of course)

From the same package you can also try glxgears , you should see 3 rotating gears.

Switching between drivers

For Hybrid graphics you might want to see PRIME.

You can override used driver using the following environment variable:

By default mesa searches for drivers in /lib/dri/ you can see the list of drivers by

driver is the name of the driver without _dri.so . If it failed it will fallback to llvmpipe.

You can also use OpenGL software rasterizer drivers by setting the following environment variables:

driver is one of softpipe , llvmpipe , or swr .

Development

Using OpenGL in code requires functions loader, read more at Khronos.

How to Install OpenGL on Ubuntu Linux

What Is OpenGL?
OpenGL is a Graphics rendering API which is operating system independent, window system independent and has high-quality color images composed of geometric and image primitives.
OpenGL APIs can use following …

• Gl
  • OpenGL API implementation (http://www.opengl.org)
• Glu
  • OpenGL Utility
• Glut – GLUT (OpenGL Utility Toolkit) – Glut is portable windowing API and it is not officially part of OpenGL.
  • OpenGL Utility Toolkit (http://www.opengl.org/resources/libraries/glut/)
• FLTK
  • FlashLight ToolKit (http://www.fltk.org/)
• GLEW…

Now lets see How to install OpenGL on out Ubuntu OS.

Now because GLUT (OpenGL Utility Toolkit) depends upon OpenGL and a number of other related libraries, if we install GLUT then OpenGL will be automatically be installed.

Run the following commands to install OpenGL.

Now to test if OpenGl libraries are working fine on our Linux, we will create a C++ program and test it.

So create a following C++ Program.

Now give the command below to compile your code.

Now run your OpenGl program with following command

If a window pops up when you run the program, then OpenGL is working on your Ubuntu OS.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. This answer suggests running glxinfo grep OpenGL which if fine, but here is some of that output:. Also the official documentation from nVidia does not mention the answer either! That is the highest legacy version the implementation will support.

There are several possibilities here:. For the core profile, there is simply no way to ask the implementation what it can support, as described in this answer :.

That glxinfo output does not mean that your driver can’t do 4. It actually can. It just means that the glxinfo aren’t aware of the presence of GL 4. The source code for glxinfo will reveal the following logic:. And OpenGL 4. So if you use a glxinfo which was compiled on a source code version before Oct 11 which means basically every distro version right nowit simply will not show 4.

It is 4. But I only know that because I know that driver. Learn more. Asked 2 years, 11 months ago. Active 2 years, 11 months ago. Viewed 6k times. I am trying to figure out which version of OpenGL my graphics card and driver currently support. Startec Startec 9, 13 13 gold badges 64 64 silver badges bronze badges. Possible duplicate of Core profile vs version string?

Only getting GLSL 1. Yep pretty much the same question however, I think that derhass ‘s answer is significantly better. Indeed it is. I learned some myself.

Active Oldest Votes. OpenGL version string: 4. The nvidia proprietary driver falls in category 2. For the core profile, there is simply no way to ask the implementation what it can support, as described in this answer : OpenGL core profile version string: 4.

So it is hard to tell, is it 4. Thanks for your very detailed answer but would you mind simplifying it a bit. You use the terms compatibility core and a new one to me » legacy «. There is no legacy profile. A used the term legacy to refer to versions of OpenGL before the profiles were introduced.

Since a compatibility profile is still compatible to applications using a legacy GL context hence the namea GL implementation might return a compatibility profile context of some higher version when a legacy context is requested, but there is no requirement to do so.

As far as your driver goes: it is capable of 4. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password.Need to find information on the graphics card on your Linux desktop environment?
