glx

问题 I have some code which includes the headers GL/glx.h , GL/gl.h and GL/glu.h . I do not even know what these are, and Google is not a lot of help because there is so much noise in the search results. So (optionally) what are they, but more importantly, how do I install them on a Mac (Mac OS 10.15.4). I have installed other stuff using homebrew so that would be my preference. EDIT: By renaming the headers to OpenGL/glx.h etc, I can now find gl.h abd glu.h but not glx.h. This answer openGL glx.h

问题 I used glXCreateContext to create the contexts, but the function is deprecated and always results in an OpenGL Version 3.0, where I would need at least 4. Now, if I have understood it right, GLXContext glXCreateContextAttribsARB(Display* dpy, GLXFBConfig config, GLXContext share_context, Bool direct, const int* attrib_list); replaced glXCreateContext . The "new" function allows for explicitly specifying the major version, minor version, profile et cetera in it's attrib_list like this for

问题 I tried searching the web, but I must note that finding materials about this aspect of X programming is not really easy. I use X with GLX to create OpenGL contexts. I already know my current graphics card driver only supports up to OpenGL API version 3.3, but I want my application to be able to try to create a context with any kind of version (as it could run on other computers). My code goes like this : Version <- requested OpenGL Version (by example : 3.3) Create a context : if Version is 3

问题 When swapping between back and front buffers the content in the back buffer becomes undefined. I´d like to define it using the "windowing system", such as GLX, EGL, WGL. Using "native" renderer such as OpenGL (glClear) is my backup plan, don´t bother mentioning it. The reason it is backup is because I don´t want to mess with native rendering contexts. I´ll stick to X/GLX for this question but if you feel inclined to describe how to do it in other Environments then go ahead. From the Xlib

问题 We have an application that we want to compile, auto-build and auto-test on an virtual machine. The virtual machine "provider" has to be able to be cross-platform as we require this operation to be executed on both windows and several linux distrubtions at the same. Our application is dependent on OpenGL, and require a rather new version of OpenGL in order to work properly. We have decent experience with Oracles Virtual Box, where we are able to perform the above action with some effort,

问题 This one is a huge issue: first off, while I know a little bit about the XLib API, I wanted to test and make sure I could actually create an OpenGL rendering context (3.0) before I did anything, thus I just copied and pasted some test code and ran it. When I run the code, my output is as follows: GLX_ARB_get_proc_address GLX_ARB_multisample GLX_EXT_import_context GLX_EXT_visual_info GLX_EXT_visual_rating GLX_MESA_copy_sub_buffer GLX_MESA_multithread_makecurrent GLX_MESA_swap_control GLX_OML

问题 I'd like to create a window with transparent background and then render something onto it using OpenGL. I don't want to use the trick where whatever is behind the window is captured and then painted as a background - I want real transparency (I have composition manager running). I'm not using any GUI library (GTK, QT, ...), just raw xlib and glx. Anyone knows how to do it? 回答1: Take a look at these patches to Neverball and SDL. They seem to be based on NVidia's driver documentation. I haven't

问题 At office we're working with an old GLX/Motif software that uses OpenGL's AccumulationBuffer to implement anti-aliasing for saving images. Our problem is that Apple removed the AccumulationBuffer from all of its drivers (starting from OS X 10.7.5), and some Linux drivers like Intel HDxxxx don't support it neither. Then I would like to update the anti-aliasing code of the software for making it compatible with most actual OSs and GPUs, but keeping the generated images as beautiful as they were

问题 I have a problem as i am currently running Ubuntu Terminal on Windows 10. I also have XMing installed as my X-server(I use XMing for qemu,etc...). And i am trying to run this SDL2 Program. So i have this for main.cpp: #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <SDL2/SDL.h> #include <GL/gl.h> int main(int argc, char *argv[]) { int final_status = 1; SDL_Window *window; SDL_GLContext openGL_context; if (SDL_Init(SDL_INIT_VIDEO)) { fprintf(stderr, "Unable to initialize
