Now I think I could use a library like glx and tell it to not open any window, however I also don't want my code to depend on any windowing system library like X11, because my program simply doesn't do anything with any windows or I/O, I don't see why my program should be burdened by a dependency on X window (as some systems simply don't have X window, they may even have no graphical interface at all). My programs should only depend on an OpenGL driver.
Depending on the operating system you're using and the availability of drivers, you can do pure, headless, GPU accelerated OpenGL rendering using EGL. Nvidia has a nice developer blog about how to do it at -eye-opengl-visualization-without-x-server/
As far as I've searched, the only other option is using WebGL software renderer, that as of today only Chrome supports. Direct3D has the reference driver (which is really unstable) and Swiftshader, which is good and expensive.
I've recently built a new PC and with that a new install o garuda, this time however i've noticed that some games have the "w" icon on the KDE panel/taskbar alongside the game icon, the title is OpenGL renderer, it does not have a window and cannot be closed. The 2 games ive notice it were: League of legends (only when the client is open, when the game begins it goes away until the match ends) and the Isle (which has 2 instances of it). print atatched
I have hardware acceleration to full in my windows preferences, have tried uninstalling drivers, Driver Sweeping them, and re-installing. I have verified that I have the latest forceware drivers (x64 for my system).
If you're on Windows the OpenGL library opengl32.lib comes with the Microsoft SDK, which is installed by default when you install Visual Studio. Since this chapter uses the VS compiler and is on windows we add opengl32.lib to the linker settings. Note that the 64-bit equivalent of the OpenGL library is called opengl32.lib, just like the 32-bit equivalent, which is a bit of an unfortunate name.
Based on the answer from @allquixotic below I made another attempt to run with the wgl option, which I did by leaving that second checkbox "Native opengl" checked. I had tried this before, but it turns out I needed to do this after a reboot for it to take effect. When I run glxgears with this setup, I get a slightly different readout on the console:
GLX is a protocol extension for the X11 client-server protocol. The X11 client-server protocol is the network protocol used for communication between clients (programs that create X windows) and servers (programs that render those windows onto a screen, whether physical or virtual).
In these days of social distancing, game developers and content creators all over the world are working from home and asking for help using Windows Remote Desktop streaming with the OpenGL tools they use. NVIDIA has created a special tool for GeForce GPUs to accelerate Windows Remote Desktop streaming with GeForce drivers R440 or later. Download and run the executable (nvidiaopenglrdp.exe) from the DesignWorks website as Administrator on the remote Windows PC where your OpenGL application will run. A dialog will confirm that OpenGL acceleration is enabled for Remote Desktop and if a reboot is required.
If you get compiler errors pointing to gl.h, this is because there are some things like WINGDI which are used in gl.h but are only defined in some other header files. Include windows.h before including gl.h
If you have link errors, then you need to figure out how to link with your specific compiler/IDE.
Example : with VC++6 (which is very old by now), you go to Project->Settings and click on the links tab.
Add opengl32.lib to the Object/library modules list.
If you use other libs like GLU, add glu32.lib.
Other compiler/IDE mind need to link with opengl32.a
If your project opens other windows and you want GL on the other window as well, in each function that you have, call wglMakeCurrent(hdc, glrc) and whenyou are done call wglMakeCurrent(NULL, NULL)
Example:
This is because a GL context can be current to 1 thread. Since window 1 has a GL context and window 2 has a GL context, both can't be current at the same time. You can either create a window in another thread, this way each context is in its own thread, or if both windows use the same pixelformat, use 1 GL context for both windows. In the 2 window 1 context case, you still have to call wglMakeCurrent(hdc, glrc) wglMakeCurrent(NULL, NULL) because the hdc would be different for each window.
Windows 95b came with GL. It included a GL 1.1 software renderer. Windows NT 4 also came with a GL 1.1 software renderer. There were a few screensavers that utilized GL : for example the screensaver with the maze.
Windows XP changed things a bit. opengl32.dll now utilized Direct3D and since Windows comes with drivers for your hardware, the renderer was fast. The GL screensavers were rewritten to use Direct3D, probably version 8 since Windows XP came with DirectX 8.
For Windows Vista, Microsoft had announced that they will update their renderer to GL 1.4. My own experience shows that it is actually a GL 1.1 software renderer. For some reason, Microsoft decided to remove the Direct3D wrapper from opengl32.dll.
I have got another question in my mind When i rendering out project where i do have some objects visibility set to Visible in Renderer switch off but the Visible in Editor is on, i can still see it in viewport that is what i expected, but this Hardware OpenGL renderer avoid these setings and renders it out also.
opengl info prints information about the OpenGL implementation currently in use by MATLAB, such as the version, vendor, and graphics features that it supports. Using this command loads OpenGL. Starting in R2019a, this syntax is no longer recommended. For more information, see Version History.
opengl hardware usesa hardware-accelerated version of OpenGL to render subsequentgraphics. If your graphics hardware does not support hardware-accelerated OpenGL,then MATLAB uses a software version instead.
opengl hardwarebasic usesa hardware-accelerated version of OpenGL, but disables some advancedgraphics features that are unstable with certain graphics drivers.If your graphics hardware does not support hardware-accelerated OpenGL,then MATLAB uses a software version instead.
opengl('save',pref) sets your preferences so that future sessions of MATLAB on this computer use the preferred version of OpenGL. Specify pref as 'software', 'hardware', 'hardwarebasic', or 'none'. This command does not affect the current session.
Hardware-accelerated OpenGL, specified as hardware.All systems support using the opengl hardware commandto switch from basic hardware to hardware OpenGL. However, only Windows systemssupport using the opengl hardware command to switchfrom software to hardware OpenGL. To switch from software tohardware on Linux systems, start MATLAB with the -nosoftwareopengl flag.
The version of the OpenGL implementation. Todetermine the version in use, check the Version fieldreturned by opengl info. To get the latest versionavailable for your graphics hardware, upgrade your graphics driversfrom your computer manufacturer website. For more information on upgradinggraphics drivers, see System Requirements for Graphics.
There are no plans to remove support for these syntaxes at this time. Instead of calling opengl to get the renderer information, call the rendererinfo function instead:info = rendererinfo(ax)Specify ax as any type of axes or a chart that can be a child of a figure (such as a heatmap). The output is a structure containing most of the same information as the opengl function provides.
Unified back/depth buffer. Enabling this option allocates one back buffer and one depth buffer for applications that create multiple windows. Turn on this option to use video memory more efficiently and improve performance.
When using the Octave for Windows installer, the user has the option to selectbetween "System OpenGL" and "Software OpenGL" renderers. This option selectswhether software rendering is used for the OpenGL graphics toolkits("qt" and "fltk"). Software rendering can be used to avoidrendering and printing issues due to imperfect OpenGL driver implementationsfor diverse graphic cards from different vendors (notably integrated Intelgraphics). As a down-side, software rendering might be considerably slowerthan hardware accelerated rendering (and it might not work correctly on 32-bitplatforms or WoW64). To permanently switch between hardware acceleratedrendering with your graphics card drivers and software rendering, use the"OpenGL Switcher" application from the Start menu while Octave is closed.Alternatively, rename the following file while Octave is closed:
octave-home\bin\opengl32.dll
where octave-home is the directory returned byOCTAVE_HOME, i.e., the directory in whichOctave is installed (the default isC:\Program Files\GNU Octave\Octave\Octave-version\mingw64).Change the file extension to .bak for hardware rendering or to.dll for software rendering.
An extension to this would be that the program could be used interactively and with graphical windows from a remote server (like an HPC computer) by using vnc or a similar protocol and having hardware accelerated OpenGL.
I am running it on a laptop which is connected to a HP 3005pr Port Replicator. This port replicator drives my two external monitors and as such windows 10 selects 'DisplayLink' as the video driver. In this mode, when starting PrusaSlicer, I get the error that it requires OpenGL 2.0.
I have a working renderer implemented with Java in JOGL with NEWT. Now I want to implement a Material Editor which should run in a second window. However I can't get a second window up and render in it.
I'm using windows server 2019 and a few quadros in a bare metal server that was working flawlessly without having to change this Group Policy. After some changes to the RDS licencing and re running the RDS wizard this was then disabling the GPU by default.
